New wireless hard drive for iPad now available

You can get it drivin’. You can get it flyin’. You can get it loungin’ in a hotel … Matter o’ fact, I got it now. Movies streaming from a wireless hard drive.

A new wireless hard drive from Seagate is set to revolutionise the way travellers store and share movies, photos and info while they’re on the move.

The GoFlex Satellite hard drive is much like a standard USB hard drive, except that it has an inbuilt battery that lasts for five hours between charges, and high speed Wi-Fi built in.

As a result, anything a traveller has loaded on to the hard drive is available to their laptop, iPad, iPhone, iPod Touch or Android-based smartphone.

The Wi-Fi built in to the hard drive is the fastest available — the “N” type — which Seagate says will allow up to three iPads to stream a movie at once from the hard drive.

(On the flip-side, it’s no more than three — Seagate is limiting the maximum number of devices that can connect to the hard drive to three at any one time — a precautionary measure to ensure good performance for each user.)

Laptop users can access files on the hard drive directly on their computers without an app — it comes up in My Computer or the Mac OS X “shared devices” list as a networked hard drive.

It also comes with a compact A/C wall charger, as well as a car charger for use on the road. (Nice that Seagate is not going down the path of providing nothing but the USB cord for charging, as Apple has done with iPods nowadays.)

HP 485041-003 battery – Brand New 4400mAh Only AU $60.85

Toshiba portege m500 battery – Brand New 4400mAh Only AU $60.31

Dell studio xps 1647 battery – Brand New 4400mAh Only AU $72.05

It comes with a three year warranty, too — longer than most bits of tech, and especially good for travellers who might be subjecting the drive to a bit of rough and tumble.

The capacity of the hard drive is 500GB, which should be enough for 300 movies at 720P HD resolution.

Seagate has made a special app for iPad/iPhone/iPod Touch which provides a menu system for accessing stuff stored on the hard drive. You can already download it from the iTunes App Store though the drive itself won’t be available until July.

The one big downside of the drive is that because it creates its own Wi-Fi network (which isn’t connected to anything except the hard drive), any laptop or iPad connected to it can’t access the internet via Wi-Fi.

To get on the net, you have to disconnect from the hard drive’s Wi-Fi network and reconnect to another Wi-Fi hotspot, or a 3G network.

Seagate says it is planning to fix this with a software update, making it possible for the GoFlex Satellite hard drive to act as a Wi-Fi extender for an existing Wi-Fi network such as one of the compact travel routers that many travellers user to set up a Wi-Fi network in their hotel room or one of the many MiFi type 3G/Wi-Fi modems.

Top 7 Ways to Track Hot Trends on the Internet

As the Internet progressively moves towards real-time information, the need to know what’s popular right now is becoming increasingly important.  Here are the best ways to track trends of all types, so you’ll always be in the know about what’s hot on the Internet.

1. How to track popular Internet video trends

magma 7 Ways to Track Hot Trends on the Internet is the definitive source when it comes to tracking what’s hot for Internet videos.  It aggregates all the hot videos from sites like YouTube, Vimeo and Daily Motion, takes into account social media buzz, links, positive reviews, how fast views are growing, then and shows you a selection of videos which are up and coming.

Because it tracks chatter from around the web and links to the video as well, using, you’ll usually be able to watch viral videos very early on rather than waiting for it to hit the masses.

2. How to track hot Twitter trends

trendistic 7 Ways to Track Hot Trends on the Internet

Trendistic is one of the most visual ways to track Twitter trends out there.  What I really like about it is that it helps you understand popular trends, and the tweets that were happening at that particular point in time when the topic became hot.  Many other services just show you what’s hot and the current tweets about that topic (you can also get that here), so there is little retrospective understanding about what actually happened when the topic was trending and became viral.

It also offers up some great tools like hourly/weekly/monthly charts, and the ability to embed these charts into your own website.

3. How to track popular search trends

googletrends 7 Ways to Track Hot Trends on the Internet

Google Trends Hot List shows you the hottest searches on the web right now.  Close to real time, this is probably the single greatest indicator as to what people are searching for now.  Google trends of course also allows you to track buzz of any given keyword across time.

Trendy Bing uses Google Trends hot list, but the results are published in Bing instead of Google.  The result is a slightly richer experience with videos and photos to complement the search results.

4. How to track popular image trends

diggimages 7 Ways to Track Hot Trends on the Internet

Digg Images is my favorite location when I want to find out what images are taking the Internet by storm.  While Digg showcases all the most popular content of every genre be it videos/news/tech, the image section is particularly unique as there are few sources online which really capture what images/photos are really popular now.

5. How to track popular news trends

newsmap 7 Ways to Track Hot Trends on the Internet

Newsmap is a fantastic visualization tool when it comes to determining what news is hot right now.  It aggregates Google News and makes the more popular (the more written about) stories larger and more prominent, so in one glance, you’ll be able to see what’s hot.  You can also customize it by topic and location to give you an even more focused look.

6. How to track popular feed subscription trends

feedcompare 7 Ways to Track Hot Trends on the Internet

Website subscription can be considered the ultimate gauge of reader loyalty.  These are people who have signed up and subscribed to your news/blog feed, and want to be notified every time something new comes out.  In terms of measuring loyal readers, this measure makes more sense than raw traffic.

Feed Compare is a free way to compare and chart RSS subscription of most websites (if they use feedburner).  Just type in the websites you want to compare, choose the timeframe, and just compare away!

7. How to track your email trends

mailtrends 7 Ways to Track Hot Trends on the Internet

No, there isn’t a service which allows you to track what people are saying on email :)  There is however, one called ˜Mail Trends’ which allows you to track what you are saying on Gmail.  It allows you to get more insight on key email stats for example:

  • Distribution of messages by year, month, day, day of week and time of day.
  • The top senders, recipients and mailing lists you’re on.
  • The distribution of thread lengths and the lists and people that result in the longest threads

Try it, the results may surprise you.

Do you track any other popular trends?  Or do you have different ways of tracking them?  Tell us in the comments :)

New Android Smartphone HTC sensation reviews

Alongside the Samsung Galaxy S2, the HTC Sensation has been laid down as the benchmark for Android success. On paper, this is an absolute stunner, chock-full of the very latest tech and the best software available. But how does it stand up to rigorous testing? Read our review now to find out.

First impressions

HTC Sensation

To hold the HTC Sensation is to realise just how far the Taiwanese mobile maker has come in just a few short years. The build feels, well, sensational. Its rounded back means it sits easily in the hand, especially important considering the vast 4.3-inch screen sitting on top.

Ultimately though, this takes its cues from HTC’s other Android devices, with the same three-tone rear as the Desire S, the same soft keys down below and the wide, tapered earpiece up top.

That’s not a criticism, more that HTC clearly prefers evolving the look of its phones rather than going in for extreme design overhauls. Add in new HTC Sense software, Full HD video and an ace camera, and you’re looking at a real winner. If you’ve already got a HTC phone, you’ll love this.



htc sensation back

As mentioned above, the curved rear makes this phone a delight to handle, whether tapping out texts in portrait mode, or watching video and browsing web pages in landscape. In comparison to its key Android rival, the Galaxy S2, it feels more considered.

The latter is neat, but lacks design flourishes, while the Sensation’s edge-to-edge glass, well-placed and obvious soft keys and HTC’s standard battery cover make this a better bet.

That said, this does once again show that Android phone makers are still not quite up to the standards of Apple and Jony Ive. The iPhone 4’s sharp looks still can’t be beaten, but HTC certainly comes close with the Sensation.



The Sensation’s key features are all about tweaking and amping-up the Android experience. The 1.2 GHz processor means things move at lightning fast pace, whether that means flipping from app to app, or just scrolling through web pages. 1080p HD video recording is very slick, with images looking beautifully defined.

As ever, with mobile phones and pocket camcorders, the sound isn’t quite up to snuff. That’s an issue if you’re making a lengthy masterpiece, but not so bad if you’re making quick clips to load up on YouTube. The on board editing smarts aren’t as good as those on the Galaxy S2, however. It’s simply a case of trimming footage before uploading it, rather than being able to cut and move shots. This can be done by snagging a third-party editor from Android Market, but is a shame considering video is at the front and centre of this device.

The eight megapixel stills camera is a real winner, however. With dual LED flash, it’s great for taking snaps for social networks and works as an ample compact replacement on nights out, working well in low light. The Instant Capture feature also means you don’t end up missing a shot while the camera tries to catch up with you. It’s a major breakthrough when it comes to camera phones.




Android 2.3’s skills are very much in evidence on the Sensation, with personal hotspot and beefed up keyboard smarts. But it’s HTC Sense 3.0 that steals the show. The active lock screen now lets you dive directly into the camera, email, SMS or phone functions without having to unlock the phone fully. The web browser has been given a makeover too, with multi window access. In practice, this is great, giving a slick approach to the web unseen on other Android devices.


Ease of use

HTC Sense 3.0 makes the Sensation one of the breeziest phones to use on the market. Issues could arise if this affects the upgrade path of the underlying Android software, but for now the custom skin makes everything tick along brilliantly. The UI is a doddle to understand and there’s no sluggishness thanks to the 1.2GHz processor. The Sensation is truly stunning.



  • Android 2.3 Gingerbread with HTC Sense 3.0
  • 4.3 inch, 540 x 960 capacitive touchscreen
  • 8 megapixel camera with 1080p HD video recording
  • 3.5mm jack
  • Wi-Fi, HSDPA, 1GB storage and microSD expansion

Overall: 9/10

11 Best Tablet Alternatives to the iPad

Top 15 Ultimate Tips to Extend Your Laptop Battery Life


HTC planning one something unique tablet

HTC is planning a tablet — and it claims to have a real trick up its sleeve to challenge the likes of the iPad, Asus Transformer Prime and Google Nexus 7.

HTC told PC Advisor that a tablet is definitely on the way, and that it will have “something unique to offer”.

HTC’s only entry into the tablet game so far has been the HTC Flyer, pictured above, one of the earliest 7-inch tablets. Despite the name, the Flyer never took off. But with the success of the Amazon Kindle Fire in the US and the coming of the Nexus 7, compact 7-inch tablets are much hotter now than they were then — could HTC be looking at building another dinky slate?

The fact the latest version of Android has arrived works in HTC’s favour. The Flyer used Gingerbread, an older version of Google’s Android software that wasn’t designed for the larger screen of a tablet. But version 4.1 Jelly Bean works across phones and slates. Arriving this month on the Nexus 7, Jelly Bean is here in good time to make an appearance on a new HTC device.

At least the Flyer had a decent tablet interface, in the form of a tweaked version of HTC Sense, the interface for HTC phones.

But most importantly, what’s the unique feature set to be? The Flyer was unusual at the time for including a stylus. That’s no longer unique, however: the Samsung Galaxy Note comes with an S-Pen stylus, and even Apple has worked on souping-up the humble pointer into a fancy digital pen.

The market-leading iPad provides the tablet template, and in order to stand out, many other tablets have had to come up with their own gimmicks. The Sony Tablet P folds in half, the Microsoft Surface has a kickstand, the Transformer Prime docks with a keyboard, and the BlackBerry PlayBook… er… makes an excellent doorstop.

I’m interested to see what HTC comes up with. The Flyer was a false start, but HTC makes great phones — like the excellent One X and Sensation XE — so an Android tablet could be just the ticket.


Top 10 reasons why the HP TouchPad is better than the iPad

Make no mistake: the iPad is a great device for what it is. But here at Top10, we are trained by ninja monks to look past Steve Jobs’ reality distortion field and recognise a better product when we see it. The HP TouchPad, which runs on the same webOS platform as the ill-fated Palm Pre, looks the part and may finally give what is doubtless a fantastic OS its due. Here are ten reasons why.

1. Faster, smarter

HP TouchPad Snapdragon processor

The TouchPad is the first device to use Qualcomm’s latest, snappiest Snapdragon processor yet – the APQ8060. This comes paired with an Adreno 220 GPU and 1GB of RAM – four times that of the iPad – to deliver the most powerful multitasking tablet yet, with unmatched 3D graphics processing for gaming and buttery smooth video playback in HD. The iPad can’t touch this.

2. UI to die for

HP TouchPad UI and multitasking

webOS has a user interface that makes Honeycomb look like a bad metaphor for Windows 95 and makes iOS feel a been-there-done-that. Not only does it ooze elegance, it scales beautifully on the TouchPad’s massive screen. Take the virtual keyboard, for example, which is resizable in small, medium and large to cater for even those who grew up near a nuclear plant. The iPad, meanwhile, only comes in extra large iPod Touch.

3. Front-facing camera

HP TouchPad video calling

Unlike some devices, the TouchPad doesn’t cut corners with obvious features just so HP can fleece you for your roubles with another slightly updated version of its tablet a year later. No, that’s Apple’s job. A front-facing camera with video calling, is it so much to ask? HP, says no.

4. No multimedia apartheid

HP TouchPad Kindle and Flash

Apple may treat Flash like a redheaded stepchild, but the rest of the world knows better. Flash is ubiquitous and the dominant multimedia platform on the web. While we certainly have high hopes for the wondrous HTML5, we can’t fathom why you’d keep Flash out in the meantime. HP TouchPad supports Flash AND HTML5. Who says the two can’t co-exist?

5. It talks to your phone

Not only does the TouchPad automatically sync data with the Pre 3 (that would be HP’s upcoming, all-improved threequel to the Palm Pre), meaning you’re never too far from all your important data, it even receives calls and messages right on the device.

Why get up from your comfy sofa when you can answer your call and receive messages on the TouchPad? Did we mention it takes video calls too?

6. Just Type

Just Type takes the concept of universal search and gives you something better. Want to see if there’s any new mail from your chum? Just Type. Want to tweet how great your day has been? No need to launch the Twitter app. Just Type. I’m sure you can see where this is going.

If this were a feature in the iPad, it would be hailed the second coming. With webOS, innovation is not a feature, it’s just there for you to enjoy.

7. Sharing is caring

HP TouchPad Touch-to-share

Speaking of innovation, and we do not use the word lightly, the TouchPad also features what HP calls ‘Touch-to-share’.

Suppose you’re browsing a website on your TouchPad and need to go out but can’t take the tablet with you. No worries. Simply touch your Pre 3 on the TouchPad and it will automatically load up the page on the handset. And you can do the same with documents, pictures, anything the Pre 3 can handle. Touch the iPhone 4 anywhere and it might as well cough and die.

8. Look mom, no wires!

HP TouchPad TouchStone wireless charging dock

Like the Pre, the TouchPad has its own wireless charging dock, the TouchStone. And by ‘wireless’ we mean no connecting bits to the tablet itself. Just place it on the dock and it will start charging, even when it’s inside its case. And while it charges, it will go into Exhibition Mode, which can display anything to your liking, be it a slideshow of your family photos, agenda of the day or your social network updates.

9. Wireless Printing

HP TouchPad wireless printing

You don’t become the world’s largest technology company without selling a few printers along the way. And HP has sold millions, no wait, tens of millions – all of which will be compatible out of the box with the TouchPad.

10. ‘True multitasking’

HP TouchPad multitasking

This is not just some marketing jargon HP keeps throwing around. It’s actually true. There really is no mobile OS out there that does multitasking better than webOS. No one even comes close.

The ever-mesmerising ‘cards’ metaphor in webOS gives you an actual view of the apps you’re running, not just a set of icons of apps in limbo. Open an app related to one you were looking at before and it will automatically get ‘stacked’ with that app. If you need to, you can always relocate it to another stack or give it its own space. Switching between apps is simply a matter of flicking through the cards or stacks of cards and tapping the one you want to open. And once you’re done, just flick it upwards to throw it off the screen. That simple.

HP’s product manager Sachin Kansal sums it up best: “in webOS, multitasking was not an afterthought”. We couldn’t agree more.

Top 5 Best iPhone & iPad Apps for Exporting and Importing Your Photos

With so many wireless iOS networking apps for the iPhone, iPad, and iPod touch available, there’s very little reason to connect any of these devices to iTunes, except to update the software. Besides, importing and exporting photos using iTunes has never been one of the best features of Apple‘s mobile device process. Let me introduce you to 5 useful apps for importing and exporting photos to and from your iOS device(s).

1. DropBox

The 5 Best iPhone/iPad Apps for Exporting and Importing Your Photos

First off, if you’re an iOS device user, you should definitely have a file sharing DropBox account and app. Dropbox is one of the best ways to sync files between computers and mobile devices, because all your files can be accessed, over Wi-Fi and 3g, via your online account. The latest version of DropBox now allows bulk upload of photos and videos to your account. With the Dropbox installed on your Mac, it’s really easy to drop image content into a folder and then download it onto your iOS device, and vise versa. Another benefit of having Dropbox is that you can connect to your account from within many of the leading wireless file sharing apps, such as they ones I’m describing in this article.

2. PhotoSync

The 5 Best iPhone/iPad Apps for Exporting and Importing Your Photos

What I like best about PhotoSync is that it allows you to selectively choose photos and movie files that you want to sync between your iPhone and iPad, and any computers on your Wi-Fi network, or with a BlueTooth connection. You can even directly import photos from your iOS into your iPhoto and Aperture libraries. PhotoSync also includes a free Mac client for exporting images from your computer to your iOS device(s). And like many photo syncing devices, you can use PhotoSync to transfer files to your Dropbox and Flickr account.

3. RemoteSnap

The 5 Best iPhone/iPad Apps for Exporting and Importing Your Photos

RemoteSnap almost instantly transfers your images directly to your Mac or PC over Wi-Fi—as you snap them on your iPhone, or select existing images from your iPhone Camera or Photo Library. To use RemoteSnap, you will need to download app to your iOS device, and then install the free “RemoteSnap Server” client on your Mac or PC. The setup is very easy. With RemoteSnap’s instant transfer feature, you could set up a Hazel automation to automatically open and display images as they are sent via RemoteSnap, which means others can view your images as you take them.

4. PicBox

The 5 Best iPhone/iPad Apps for Exporting and Importing Your Photos

If you would rather not waste time selecting photos in your iPhone Camera Roll to upload to Dropbox, download a free copy of Picbox, which automatically copies entire Camera Roll of photos and/or videos to your Dropbox account with one single tap. On top of that, Picbox keeps track of which images it has already uploaded to your account. It does not erase your original images on your Camera Roll, it simply copies them to your account.

5. CameraSync

The 5 Best iPhone/iPad Apps for Exporting and Importing Your Photos

As you may have noticed, each of the apps I have described do basically the same thing, but in a slightly different way. But for a completely hassle-free uploading of pictures and video from your Camera Roll to your Dropbox, iDisk, FTP server, Amazon S3 bucket, Flickr or account—CameraSync will automatically begin the upload process right after you open the app. CameraSync can do all the uploading in the background, which means you can switch away from the app and do other things on your iPhone. CameraSync will also keep track of which images and videos it has already uploaded.

Yes, CameraSync and PicBox are nearly the same, the only difference is how fast you want the upload process to begin.

Well, the above are my picks for the top photo syncing apps. Let me know which ones you prefer.

Dell latitude d620 laptop battery buying tips

Things to remember order Dell Latitude D620 battery

Every laptop battery is given a power rating in order to show you, the consumer, about how long your Dell Latitude D620 battery should last before it needs to be recharged. These electrical specifications are given using volts (V) and milliAmps (mAh). For example, you may see your Dell Latitude D620 Laptop Battery is given a rating of: 11.1V, 4400mAh.

Volts and milliAmp hours are used because they measure the amount of energy used by a Dell Latitude D620 battery. A volt (V) is a measurement used for the amount of pressure the positive and negative electrodes produce in a laptop battery pack during the process of discharging energy. Amps (A) measure the amount of resistance the energy in your Dell Latitude D620 battery produces in order to power a laptop.

You may also notice that increasing the size of the pipe and shower head without having to open the faucet all the way will produce similar results.This is an example of the amount of resistance in the flow of energy. Measuring this resistance is measured in terms of amps. In terms of a Dell Latitude D620 battery, the amount of resistance is dependant on the size of the Dell laptop battery and the amount of energy inside.

Laptop ratings are given in terms of amp hours (Ah). Amp hours measure the length of time a Dell laptop battery will discharge energy before it needs charging. In order to adequately measure v, manufacturers use milliAmp hours (mAh). This means that every 1000mAh is equal to 1Ah. What does this mean for your new Dell Latitude D630 Battery? If your original Dell Latitude D620 battery is measured at 2500mAh and your replacement Dell laptop battery is measured at 5000mAh, then your Dell Latitude D610 Battery run time will double.

Keep in mind that technology constantly changes. Your old Dell D620 battery may be rated at a lower run time than a newer one because of technological advancements that have produced longer lasting laptop batteries.

One way of conserving Dell Latitude D620 battery is to go to your Power Management settings icon in the Control Panel. You can shut off settings or programs you do not use. Also consider dimming your screen and shutting off your wireless card when you don’t need it. In this way, you can save your Dell Latitude D620 battery a lot.

Things to Know Before Buying a Replacement Laptop Battery

There are many laptop batteries manufacturers, and even more retailers to buy your laptop battery from. However, your biggest concern in purchasing a laptop battery will be to choose the battery that fits your computer. For this you will need to know the make and model number of your laptop; if you don’t know this offhand or don’t have the necessary paperwork, check the inside of your laptop’s battery compartment while the computer is off and unplugged. There you should find the model number, along with some other information. You may also find the part number of your laptop battery, located on the casing of the battery itself.

How to Choose a Replacement Laptop Battery

When buying a laptop battery, you will probably only have one or two choices that fit your computer. Choose the battery with the longest life available for your computer. There are several different kinds of laptop batteries; because the battery technologies of each are very different, a laptop must be designed specifically for the type of battery it uses. Most laptops are only designed to use one type of battery technology.

Lithium-Air Batteries Set to Increase Efficiency

Research is underway on a new class of rechargeable powerpack known as a lithium-air or lithium-oxygen battery. These devices could store more than 10 times the energy found in current lithium-ion batteries, which would greatly extent the time required between recharging cycles. Because lithium-air uses freely available oxygen as a cathode reactant, the weight of the battery significantly decreased.

Lithium air battery MIT

These power cells could even beat the energy density of hydrogen fuel cells, making one efficient lithium-air car battery able to store the equivalent energy of a tank of gasoline. The battery technology is not yet commercially available, although it’s actively being developed in several places.

The Massachusetts Institute of Technology (MIT) has developed a lithium-air battery with three times the energy density of any existing battery on the market today. One prototype is pictured above. MIT researchers state that some of the issues that must be dealt with before commercialization of these new laptop batteries is safety in operation and insuring that the battery is robust enough to survive many charging cycles.

Although MIT has discovered that electrodes with gold or platinum show a much higher level of efficiency than simple carbon, lithium in metallic form is highly reactive to water. This poses a problem should water make its way into the oxygen inlet of current lithium-air prototype batteries. Researchers are working to better understand how the chemistry of these substances affects longevity through discharge and recharge cycles as well.

Some companies have stated a ten-year goal for full commercialization of lithium-air battery technology. MIT researchers believe that small portable electronics will be the first to benefit from the improved batteries, with products such as electric cars taking advantage of the devices after they come down in price and become more widely available.

Need to Activate the New Laptop Battery?

In fact, the activation of the battery work in the factory should have been completed, notebook battery factory a little carried by the natural loss of power is to avoid damaging the battery. Activation of the battery protection circuit should be in no manner, and can be lithium laptop batteries with protection circuit itself, the purpose of the circuit design blocks is to avoid over-charging and discharging the battery, usually when the battery is fully charged, the charging indicator light extinguished the moment, the battery is not charging the state, then this time you then plug the battery charger to charge the above do not have any meaning. We can see from the Hp presario cq60 battery on the status of the battery is charging, there is a simple way to determine if the Hp probook 4310s battery is charging, the battery charge is going to be distributed in a certain degree of heat, after an hour when the Hp nc8430 battery is full (battery charger do not pull the power plug is temporarily down), you go touch the battery, this time you will find that the battery is at room temperature, it is because the battery charge status at this time has not, of course, there will be no heat generated.

How to Charge Laptop Battery?

Whether to use lithium batteries or Ni-MH Laptop battery, these batteries are a memory effect, Ni-MH battery memory effect significantly, lithium also has memory effect, but its memory effect compared to nickel-metal hydride smaller only. We have not heard of the so-called memory effect lithium argument, but that is exaggerated in some js to say, the purpose is wrong to guide consumers. Since the lithium Aspire 3680 battery has memory effect, then in charge should try to run out of rechargeable electric, Do not want to charge when the charge went, so although it convenient to use, but will shorten battery life. However, we did not need to completely run out of power again so charged, so too much trouble. Although this protection because the battery is not under the protection of the circuit will not destroy the Aspire 4710 battery, but nothing special needed. In fact, less than 3% of the electricity charge on it, the memory effect is an objective reality, but compared to natural wear and tear, it is not what it is.

Need Remove the Battery When using an External Power Supply ?

In fact, this depends on when you use an external power supply is not required to charge the battery, rechargeable battery is directly related to the life, in general, lithium battery charge and discharge times are fixed, the charge number to only 500 or so, at most not more than 800 times. Each of our battery to recharge a battery, the corresponding, thus reducing a number of charge cycles. But now many notebook manufacturers are taken into account the vulnerability of cells in increasing protection for the battery technology does not meet certain conditions will not be charged. Even so, when you use the computer for a long time when an external power supply is recommended that you disconnect the battery because the battery temperature is also the bane of one of the laptops in use will have a certain temperature, which is very harmful to the Travelmate 4200 series battery. Of course, if you are not sure of your battery, then I suggest you to pull down your battery and then use an external power.
