How to Choose a Replacement Laptop Battery

When buying a laptop battery pack, you will probably only have one or two choices that fit your computer. Choose the HP elitebook 8530w battery with the longest life available for your computer. There are several different kinds of discount laptop batteries; because the technologies of each are very different, a laptop must be designed specifically for the type of Apple a1185 laptop battery it uses. Most laptops are only designed to use one type of battery technology.

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 Top 7 Ways to Track Hot Trends on the Internet

Mag.ma 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 Mag.ma, 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 Top 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 Top 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 Top 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 Top 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 Top 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

Cell Phone Battery on the iPhone 5

After the iPhone 5 craze dies down, you’ll have ample time to see how well you actually like the device.  Is it the phone that has all of the feature you have dreamed of?  It is very close, but it all really depends on what you need.

iphone battery Cell Phone Battery on the iPhone 5

For those who are considering the jump to the iPhone 5, what is holding you back?  There will always be a few glitches that arise as a result of the release of a new electronic product or program.  For most high volume users, the most common gripe will be the short amount of time the battery will last before needing a charge.

Nobody wishes to get an irritating signal as “low battery” in midst of an important phone call or text message.  Text messaging on your iphone is not as hard as the new phone you will get next.

Several lawsuits have been filed regarding the iPhone battery.  Users get upset when they discover that the iPhone battery is sealed and can not be changed.  The iPhone’s battery cannot be changed.

Swapping phone batteries is common, so iPhone owners feel a warning should be issued.  Nonetheless, keeping a recharging dock in more than one location (whether at home or in the workplace).  This is a way to get around the iPhone battery issue.

The iPhone 5 will probably have two options–the 6 GB version or the 8 GB model with greater memory.  Compared to what features come with an iPod, this what is a little small.  The 20gb model may cramp some users’ style, and there is currently no memory expansion option.

Apple vastly approved sites and is possible to download a high volume of files from pirate sites.  One can download films, television programs, music, pictures, and games, among other content.  Users complain that iPhones tend to download information too slowly.  Most iPhone users find delayed downloads to be infuriating, however if you plan ahead, you will be able to make it less frustrating by devising a schedule.

Cell phone users used to be few and far between.  When they are unhappy with the service of one provide, they will easily walk on to the next.

How will the search tools in the iPhone 5 work with all the features available on the device?  Will the browser have the option to automatically remember passwords?  The iPhone 5 is the best model, and all problems are addressed.

Apple Claims New iPad’s Battery Charging is Normal

new ipad battery iphoneaccessories supplier.com  Apple Claims New iPads Battery Charging is NormalThe new iPad‘s battery performs within the normal parameters of an iOS-based device, thank you very much. At least that’s the story Apple is telling in the face of criticism of the way the company’s latest tablet deals with battery charging.

Apple told All Things D and aussiebattery on Tuesday that there’s been some “confusion” about the way the new iPad charges up its battery when users plug it into a wall socket.

When the tablet reaches a nearly 100 percent charged state, the new iPad displays the battery as being fully charged, Apple’s Michael Tchao told the tech site. When that happens, the battery actually continues to charge all the way to 100 percent—but if it remains plugged in, it decharges a little, then charges back up fully, then back down again, and so on until the user unplugs the tablet.

Tchao billed that process as a boon to new iPad owners.

“That circuitry is designed so you can keep your device plugged in as long as you would like,” he told All Things D said. “It’s a great feature that’s always been in iOS.”

Apparently, Apple has been doing the same thing to manage the battery charging of several iOS-based devices, including iPhones, iPod Touches, and iPads, for several product generations. It just hadn’t gone noticed by many folks until a DisplayMate analyst grokked that his new iPad wasn’t fully charged even though the display indicated that it was, according to All Things D.

So basically, plugged-in iOS devices cycle between a completely charged state and a slightly decharged state, but Apple doesn’t reflect this in the Toshiba Satellite pro a120 battery status on its devices because it could “distract or confuse users,” according to Tchao.

DisplayMate’s Ray Soneira may have noticed the discrepancy between his new iPad’s actual battery charge and what the display was telling him it was, because the device takes a lot longer to power up its much bigger battery when plugged in than its predecessor, the iPad 2.

As PCMag lead mobile analyst Sascha Segan noted last week, “the new iPad appears to charge very slowly,” even though it’s actually charging just as fast as the iPad 2—naturally, because it uses the same power adapter. But as Segan points out:

The iPad’s 42.5 watt-hour battery is unusually large for a tablet. It’s more like a laptop battery. Both the 11-inch MacBook Air and Asus‘s Zenbook UX21 have 35 watt-hour laptop batteries. The previous iPad and the Asus Transformer Prime, the two major competing tablets, both have 25 watt-hour batteries.

But the new iPad comes with the same power adapter as the previous model, putting out 10 watts of power. That’s much less than the standard MacBook Air power adapter, which puts out 45 watts to charge a smaller battery.

The result is that the new iPad appears to charge very slowly. It’s charging just as fast as the previous iPad (it uses the same power adapter, Toshiba Satellite L300 Laptop AC Adapter), but it’s filling a bucket almost twice as big with the same trickle of water.

What that could mean is that the amount of battery charge that a plugged in, fully charged new iPad decharges itself by per its design would be quite a bit more noticeable to users than with earlier iPads (and iPhones and iPod Touches), because the amount of time it takes to cycle back to a fully charged state is just that much longer.

Of course, Apple has been taking some flak related to the new iPad’s battery life that extends beyond just the way the third-generation tablet charges up. As Segan also noted last week, the new iPad’s promised battery life of ten hours (actually ten hours, 54 minutes in PCMag testing) is possible—if you cut the screen brightness to 50 percent. At full brightness, the new iPad’s glorious and pixel-loaded Retina display burns through the tablet’s extra-large battery twice as fast.

 Google Nexus 7 teardown reveals better battery than Kindle Fire

Google Nexus 7 Google Nexus 7 smaller but longer battery life than Kindle Fire

A full teardown of the new Google Nexus 7 has revealed the tablet is packing a seriously impressive battery under the hood.

The Nexus 7 comes with a 4,326mAh, 16Wh battery which can reportedly last a whopping 9 hours, 50 minutes, according to the chaps over at iFixIt.

This might not seem impressive when you consider the Amazon Kindle Fire packs a 4,400mAh battery, but even though its got a bigger power laptop battery pack, you can only squeeze seven and a quarter hours out of it.

On par with iPad

With the quoted battery life almost topping ten hours, it places the Nexus 7 battery in line with the new iPad, which sports an 11,500mAh, 42.5Wh juice pack, with the 3G iPad offering 9 hours 52, and the 4G model providing 9 hours 37 minutes of life.

If you like to tinker with your hardware, then you’ll also be pleased to know that the battery is relatively easy to access on the Nexus 7, with the rear plastic case able to pop off and Original Toshiba PA3534U-1BAS Battery reached without needing a screwdriver – something you can’t do with the iPad range.

The Google Nexus 7 is an impressive tablet, with its quad-core processor, 7-inch HD display and Android 4.1 Jelly Bean operating system, which is being powered for longer by this decent battery.

Review Dell Latitude D620 Notebook and Dell Latitude D620 Battery

Intermediate. The Dell Latitude D620 is – as the name implies, an intermediate notebook between the Dell D420, a very mobile 12 inch subnotebook, and the D820, a standard 15 inch business notebook. Its 14 inch display provides a good overview at still restricted dimensions, and is also available with a resolution of up to 1440×900 pixels.

b72ff4485c Review Dell Latitude D620 Notebook and Dell Latitude D620 Battery

Case

Also the Dell Latitude D620 tries to stress its business character by a silver and gray play of colors.  Generally, this notebooks looks decent and business-like, so, it succeeded regarding this matter.

This business aspect is again accentuated by the choice of material. The generous use of magnesium does not only give the D620 a high-quality haptics, also the stability of the case profits in total.

The base unit is very flexural rigid and resistant against applied forces. Although, sometimes creaking noises are possible, looking for deflections is a waste of time.

Also regarding the display, it gets apparent that this issue was treated important by Dell. The display’s frame is designed in a slight Clamshell design, and the cover is out of magnesium. So, the Dell Latitude D620′s display robustness is really noteworthy.

Furthermore, the display is equipped with a central transport hook, which secures the closed position of the display.

Most of its ports are provided at the backside of the case. Thereby, the 4 USB 2.0 ports and the serial port are base equipment. Furthermore, the D620 provides an integrated Smartcard slot, which is of special interest regarding security, and access restriction.

Input Devices

The D620 proves that a clearly structured keyboard does not really require a 17 inch notebook. The function keys at the top edge of the keyboard were grouped, and also the cursor keys were slightly moved to the bottom.

Furthermore, despite of the F-keys, which were slightly shortened, all of the keys have a good size. An enter key which extends over two rows and a big space bar, which though was moved a little bit to the right, are available.

Typing is affected by an early stop and possibly fast typing is rather noisy. However, in total the keyboard is alright.

Also the touch pad does not have any anomalies. Its surface is comfortable and also regarding precision and response there is nothing to criticizes.

Besides a touch pad, the D620 also provides you with a track point, whose blue plastic cover is, to our opinion, not really ideally formed. Those many sharp knobs really don’t feel good at the fingertips…

The D620 provides you with hot keys for controlling the volume above the keyboard and with a switch for activating/deactivating the wireless function  at the left side of the case.

Color Diagram

As already mentioned in the introduction, the D620 is available with different display versions. E.g, the standard version, which was used in our reviewed sample: A WXGA display with a resolution of 1280×800 pixels and non-reflecting display surface. But,e.g., also a 1440×900 WXGA+ version, for users who require more overview, is available.

The display’s maximum brightness was measured 142.7 cd/m² during our review. The illumination is only 71.7%, because the brightness heavily diminishes at the upper edges, due to the display technology used. These results are together with an average brightness of 124.9 cd/m² slightly below-average.

The color diagram depicts an ideal red and green color curve, but also the usual lowered blue color curve. So, red colors dominate.

Distribution of brightness

The minimum brightness (black value) of 0.6 cd/m² together with a maximum brightness of 142.7 cd/m² gives a rather good calculated contrast ratio of 238:1.

Operating this notebook outdoors is limited by the only moderate brightness of its display. However, its non-reflecting surface has absolutely an positive impact regarding this aspect.

Horizontally, the D620′s display can by all means be called stable to the vantage point. However, vertically, we observed troubles, especially when looking from the bottom side to the upper side. You can face a heavy darkening and the gray levels change therewith. Looking the other way round, from top to bottom, the colors hardly change, however, the contrast also diminishes.

Depending on the demands, the Dell Latitude D620 Notebook Battery is available with a number of different processors and also with two different video solutions. Thereby, the most powerful CPU solution is the currently most powerful Intel processor, the T7600 with 2.33 GHz. Regarding graphics, you can either choose the Intel 950 video card or a NVidia Quadro NVS 110M video card with turbo cache.

So, regarding CPU performance there are hardly any improvements possible. The “weakest” CPU which can be chosen the T7200 with 2.0 GHz and even more the T7600 Chip provide first-class performance for applications.

However, there is a big difference between the two available video cards. The Quadro NVS 110M video card is so to speak the somewhat more powerful and properer for 3D video card and an alternative to the Intel 950 GMA video chip. However, you cannot expect records from neither of them. The performance of the NVIDIA Quadro NVS 110M video chip is about in between a X1300 and a Geforce 7200 video card.

Whatever equipment you finally chose, the D620 is and stays an office notebook. Office applications as well as Internet applications are no problem for the Latitude. If you like to use multimedia applications, you should chose the D620 with the available NVidia video card. But, this still won’t make a 3D computer out of it.

The 80GB Samsung hard disk of the reviewed notebook rated good regarding transfer rates, but slightly below-average regarding access times. Typical Dell, you can choose between a variety of different hard disk models. The available capacity is up to 100GB for 7200 revs models and a maximum of 160GB for 5400 revs models.

Emissions

Loudness

We observed that the fan runs all the time even in idle mode (without load). However, its noise is not disturbing and with a noise level of about 32.5 dB it can also only be clearly heard in absolutely quiet environments.

Under load the fan turns a little up, but, its maximum noise level of only 37.5 dB is still alright.

Temperature

Not only the noise emissions, also the surface temperatures of the case are without any anomalies. The maximum temperature at its top side was only 33.6°C, at the bottom side was also alright with 38.4°C. So, there are no problems regarding mobile use.

The reviewed notebook came with an 56 Wh lithium ions battery. As an alternative you can choose a 9 cells dell d620 battery with a capacity of 85 Wh. This should enhance the battery runtime by about 50%.

The measured battery runtime of the 6 cell version was in between a minimum of about an hour and a maximum of a little more than 4 hours.

Furthermore, the D620 can be equipped with an Ultrabay supplement battery. Having a capacity of 4320 mAh or 48 Wh, it is able to enhance the Dell Latitude D630 Battery runtime by about 40%.

In total, the duration of unplugged usage is noteworthy, if all available resources are utilized.

Verdict

The Dell Latitude D620′s good workmanship and the high-quality materials used could throughout convince us. The case appears very compact and robust and therefore, fit for daily mobile use.
We also liked the input devices, because of the overview and the user-friendly layout they provide. Only the D620′s track point has a somewhat unergonomic form for which you might need some time of adaption.

The matt display has an adequate brightness, but a poor illumination. Other basic data like contrast and stability to the vantage point were alright. Furthermore, of interest: A 1440×900 WXGA+ display with higher resolution is also available for the D620.

The performance of the notebook depends on the chosen configuration. It is moderate with a T7200 CPU and an Intel GMA 950 video chip, but its can be improved by choosing a high-capacity configuration consisting of a T7600 CPU and a Quadro NVS 110M video card. This equipment makes the Latitude D620 a powerful office computer.

The emissions are alright, too. The noise emissions as well as the measured surface temperatures are all together without any anomalies.

Furthermore, it is possible to make the D620 fit for a longer unplugged operation by taking some steps. The battery runtime of the standard 5 cell dell battery is sufficient for about 1-4 hours, depending on the demanded performance.

Additionally, you can upgrade to a 9 cell main battery (~+50%) and additionally use an Ultrabay supplement battery (~+40%).

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.

Self-Contained Battery Concept Charges Itself

This rechargeable battery concept couldn’t be simpler. Grab the top and bottom of the dead battery and wind it up! The spring inside the battery housing then turns and charges the power cell inside. Designed by Yeon Kyeong Hwang and Mieong Ho Kang, these wind-up batteries could charge anywhere without external power.

laptop batteries charge Self Contained Battery Concept Charges Itself

The top half of the battery is the actual power cell, described in the design as Ni-mH. The bottom half twists and loads a spring inside the barrel, which as it unwinds turns a generator that charges the laptop battery. Of course, the battery can also be charged with an external battery charger to save you from having to wind it up all the time.

Assuming the concept would actually work from an engineering standpoint, it looks simple and brilliant. Already you can purchase devices that run on wind-up power, such as radios and flashlights. Turning the lever stores energy in a large metal spring. As the spring unwinds, a generator creates power to receive emergency radio information or your favorite stations.

The concept pictured is a AA battery, which would be relatively easy to wind up. Not sure how this idea could be adapted to other batteries, such as a square 9-volt. Maybe a wind-up external charger for all battery types? This would be great but the advantage of the Charge Battery is that it’s self-contained. Built-in grips on the sides of the Dell Latitude D620 Laptop Battery make it easy to wind outdoors or anywhere.

Hopefully this concept can be manufactured for use. If more electronic products used this old-fashioned technology we wouldn’t have to search for our battery chargers so often.
