Change the battery cell is not a good choice

Change the battery cell is not a good choice

cell

When we want to repair our laptop battery, we often see some laptop battery maintenance introduce the change battery cell service. You just spend 30$ or less to repair original laptop battery by change the battery cell. As buy a new original laptop battery may cost you 200 $ or more. It looks great but it is really worth?

It has some risk when changing the original Dell Inspiron 1520 Battery cell. The batteries can be changed, it is very simple because the battery inside is just some series and parallel battery packs. But the corresponding protection board can not be replaced.Most of the protection boards are added secret infomation the time in the factory , only can be debugged in Dell laptop battery production plant.

Battery Protection Board are based on the corresponding matching Dell Inspiron 1521 Battery packs to debug a good, if the random replacement of batteries while protecting the panel without doing the appropriate debugging shield of protection features may fail, so the risk is relatively large.

Another point, if a single change batteries, then is a bad, because the internal resistance of the old and new Dell Inspiron 1721 Battery do not like the efficiency of the battery pack will drop a lot, but for the life of the new batteries also have a significant impact, and we manufacturers to replace the batteries are replaced all the batteries.

Generally laptop battery life is 1-2 years, so the Dell Inspiron 1720 Battery in the warranty period, warranty or replacement directly to vendors, it is better to buy a new battery replacement when out of the warranty period. After all, the cell-change battery may damage your expensive laptop.

Differentiate Laptop Hard Drives

 

Laptop hard drives don’t spin as fast as their desktop counterparts, and this is down to the need to limit power consumption. However, it’s only when you take on intensive multimedia work and the likes of high-end games that you’ll really notice any kind of difference in everyday use HP F4809A. Do note, though, that you can get portable machines with drives that spin at 4,200rpm and 5,400rpm, and if you must get optimal performance, then it’s the latter you should opt for. You may end up paying extra for something that doesn’t make an awful lot of difference, though.

As for capacity, this - as you’d expect - is led by what you actually want to do with the machine. If it’s a simple, robust office and Internet computer you’re after, then you could be fine with just a 20GB hard drive, although you may opt for 40GB as the price difference isn’t too much. Only if you’re looking at heavy multimedia work or gaming should you really look much higher, and 80GB units aren’t too costly Compaq Evo N610C Battery.

The majority of portable machines rely on graphics technology that’s fully integrated into the laptop’s motherboard. Thus, while they’re fine for office applications, DVD playback and suchlike, they struggle when it comes to gaming PB992A.

That’s why graphics giants ATI and nVidia have invested so heavily in providing portable versions of their powerful desktop graphics technology. Their products, in terms of power, lag a generation behind their desktop counterparts, but for the vast majority of modern games Pavilion ZV5000 Battery, that’s not going to cause too many problems ,although clearly it’s a lot more difficult - yet not always impossible - to upgrade laptop graphics boards further down the line.

Buying Second-hand charger Tips

Buying Second-hand charger Tips

Buying a second-hand battery charger can save your money. Everyone loves a good bargain. Donot let your good deal become a bust by observing these simple rules of caution.

How many hours operated This may seem like an unreasonable request. Although no one will be able to tell you exactly how long they have been run. The owner should be able to tell you how it was second-hand and how often. Doing some basic calculations will give you a ballpark idea. For example a battery charger that charged a battery overnight once a week for ten years would be 8 hours x 52 weeks x 10 years would be 4160 hours. This figure is really useful to compare two or more chargers that you may be looking at but you can use it as a feel for just how good of a bargain you may be getting. The reason behind this is that the longer an electronic device is run the more likely it is to fail. Just like the human body as we age the more likely something is to fail. Two items that add to the shortening of an electronic devices life is high voltage and constant turning off and on. VGP-BPS5 Chargers provide and do exactly these two things.

A unit that is turned off and on many times will not run quite as many hours due to the stress of heating and cooling on the components. Constant temperatures help prolong electronics. If you have ever been in a room full of VGP-BPS8 computers such as servers the administrators will have the room at a constant cool temperature. It is the same idea.

How clean is it This may sound silly bit it is actually quite important. Electronic devices love to attract dust and dirt. Years of sitting in a garage can build up layers of dust and plug up vents. This covering can make VGP-BPS2 chargers heat up higher than they are supposed to and possibly shorten the life of your device. Although this is impossible to detect by buying through ebay or some other site as most sellers will have cleaned up the devices on the outside. It is, however, useful for buying from Craigslist or a yard sale or some other avenue where you can actually see and touch the device.

Age may determine options This almost goes without saying, but it is worth keeping in mind. The age of the machine can determine what bells and whistles it has. If you need just a basic laptop battery charger that you don鈥檛 mind putting on a timer yourself or can watch the time to shut it off then this shouldn鈥檛 matter. However if you need a charger that automatically changes over to trickle mode after a 80% charge then you need to keep age in mind.

Buying a second-hand battery charger can be a bargain. Most everyone can agree that a bargain can be found buying second-hand. There is always a risk, however. Keep these tips in mind when buying from Ebay, Craigslist, yard sales or anyplace place to buy second-hand.

The Sony External VGP-BPS8 laptop battery review

The Sony External VGP-BPS8 laptop battery review

I owned my Sony VGN-FZ for about 1 years. Now its original battery is nearly dead (just work about 30 minutes). Though the new battery can last about 2-3 hours when fully charged. I asked Sony Customre service if they can replace or repaire the battery for me. They said they can do nothing as the battery out of its warranty (just advise me to calibrate it).

As my work need to travel to everywhere in London, so I need a battery replacement urgently. I can not find anything from sony.com except “No match documents was found for your search. Please try with different keyword(s).” I serched in Google.com and find many original VGP-BPS8 batteries, but I cannot belive them(my last original latitude d620 battery which buing from a online shop is just a second-hand battery). So I choose a website : http://www.discount-laptop-batteries.co.uk which sell the Sony VGP-BPS8 replacement.

After view the battery detail info and website shipping return policy, I decide to buy the external 7800mAh VGP-BPS8 battery. As it is 3000mAh more capacity than my 4800mAh. I think it can last longer but the 10400mAh one is too big and heavy. I ordered the battery in October 15 and received it in 25. It cost me 95.89 pounds and 10 pound shipping fee.

To my superise the package was sent with a CD, I do not know what it is. But When I installed the Sony VGP-BPS8 battery my laptop cannot recognize the battery. So I sent a email to the customer service about this, now they replied me in time (just after 10 minutes later). They said that I must update my Bios driver with the CD to help my machine run the battery. I did this and finally my laptop can work without the adapter.

My notebook power management shows it actually 7800mAh and can last 4.5 hours. Now I can go everywhere with my VGN-SZ. Something I want to say is that the battery is a little heavy . The battery sticks out of the laptop .. so get used to the new look of your laptop. Haha. Also you can buy the VGP-BPS8 battery in their partener website: http://www.discount-laptopbattery.com

Some customer review may useful to you in Amazon (Original Sony laptop battery):

1) The laptop battery on FZ doesn’t charge up all the way or maybe it’s my laptop.
2) The battery sticks out of the laptop .. so get used to the new look of your laptop.
3) The battery stopped charging after only one week of purchase. The vendor (Infinite-Surplus) wouldn’t return the battery and asked me to go through Sony which wasn’t a great experience

I expected this battery to last longer (< 3 hrs) and didn’t realize how it’s design fits with the FZ series laptop. It props up the base of the laptop but is off-center due to the placement of the battery compartment. Make sure you lock the battery in, because it’s designed to be used as a handle for the laptop and works well that way.

HP Envy 15 review

There are laptops and then there are laptops. The Envy 15 has fallen into that second category ever since we got our hands-on: it’s the first PC we’ve seen that really equals the MacBook Pro’s unibody design and it packs a scorching-fast Intel Core i7 processor for Pavilion DV5000 Battery , ATI Mobility Radeon HD 4850 graphics and Beats speakers. On paper, this is easily the hottest laptop we’ve seen in some time, but has HP really managed to deliver on that promise? We spent a few days with this $1,800 monster, so read on to see if it lives up to the hype.

Yes, we know — at first glance, the Envy 15’s aluminum body and rounded edges bear more than a little resemblance to the 15-inch MacBook Pro. But HP’s latest is actually a bit more daring than the Apple and Compaq EVO N400c Battery, with a floral-like pattern of laser-etched divots arrayed across its lid. Not to worry, no one’s going to get the impression that this thing is sissy — especially because the magnesium-alloy frame is incredibly solid. It’s surprisingly thin and light for a 15-incher at 5.2 pounds and one-inch thick, but it lacks an optical drive, which is built into the slightly heavier MacBook Pro and  HP HSTNN-LB31 . (You can buy an external standard DVD drive for $75 or a Blu-Ray for $225 when configuring online).

The Envy 15 packs plenty of muscle with a 1.6GHz Intel Core i7-720QM processor, 8GB of RAM, an ATI Mobility Radeon HD 4830 and speedy 7,200rpm hard drive. It’s a powerful system, but that Core i7 generates a lot of heat — more on that later. Ports-wise it’s pretty much all laid out on the right side of the laptop with a hybrid audio plug for headphones and/or a mic, a eSATA / USB combo jack, two USB ports Compaq EVO N410c Battery, HDMI and Ethernet, while an SD card slot is nestled on the front bottom lip. (The Envy 15 actually comes with its user manual on a 2GB SD card, which we… read thoroughly. Right after we popped it into our camera.)

The 15.6-inch, 1920 x 1080 resolution screen under the lid is incredibly nice on the eyes, and although it’s not as intensely bright as the Envy 13, we found it to still be super crisp. Watching a downloaded 1080p clip of a Killers’ concert made us feel like we were front row at the show Compaq Evo N600C Battery ; we could see the beads of sweat beaming off of Brandon Flowers’ forehead. We would have preferred if the screen had a flush glass bezel, rather than the thick raised plastic border that surrounds it, however. Above the screen is a a “nightvision” VGA camera that uses infrared LEDs to provide illumination in dark environments. We’ll let you, kind reader, imagine what this could be used for, but we will report that the cam lives up to its promise; a Skype call made in the dark was actually visible and our face was illuminated and discernible.

What blows the HD video experience out of the water on the Envy 15 are its stellar Beats Audio speakers. (All the Envys have Beats speakers, but you can also get a $2,299 Beats-branded bundle that comes with a special black paint job, a pair of HD headphones, an ultra mobile audio interface, HP Pavilion dv4 Battery ,  and Traktor DJ software.) By far the best-sounding speakers we have heard on a laptop in a long time, that same Killers clip sounded incredibly full with a surround quality that was better than any typical cheap headphones or speakers we’ve heard.

We’ll admit that we’re happy to see the keyboard deck is void of any finicky brightness or volume touch controls, though you can change those settings with function keys. There’s also a column of dedicated shortcut keys for opening the browser or e-mail client HP Pavilion zd8000 Battery. Overall we enjoyed the typing experience; the keys themselves feel sturdy and had a nice bounce as we wrote this review on them. But HP, why no backlight?

The award for most improved touchpad goes to HP’s ergonomics team. The trackpad itself is the same glass multitouch unit with integrated mouse buttons found on the Envy 13, but the software’s thankfully been updated since our last experience with it — it takes a bit of getting used to, but most of the issues have been sorted out. Pinching to zoom gestures were responsive, but two-finger scrolling was still a bit choppy in Firefox and Internet Explorer and HP Pavilion dv9000 Battery.

Still, we generally plugged in a mouse when we used the Envy 15 — the trackpad might perform adequately now, but the palm rest got hot. Uncomfortably hot. And this wasn’t just when the system was under a lot of stress: the wrist rests and bottom would heat up with just a browser open, and temperatures got hot enough after an hour that we took it off our lap and set it on a table HP Pavilion dv2000 Battery . We surmise this is a result of the Envy’s very thin design and hardcore performance parts — there could just be too much going on underneath its short-on-space-hood. We aren’t the first to complain of the heat either, users who have purchased the system also find it quite toasty.

Software, performance and battery life

When you boot up the Envy 15 you have two choices – you can enter the instant-on HP QuickWeb OS or head right into Windows. The pre-boot environment is a nice touch and we had no problems getting connected to a WiFi network to check our Gmail HP Pavilion dv6000 Battery ,  but we doubt we’d spend much time in this interface when it takes just 20 seconds more to get into Windows 7. Speaking of Windows 7, we continue to wonder why HP feels the need to brand the entire operating system with its colors and themes. More peeving is the amount of junk on the system itself, including Norton pop-ups, semi-automated HP Pavilion dv8000 Battery software updaters/assistants and HP’s MediaSmart toolbar and software — after a while we were longing for our pristine install of 7 Home Premium. We’d even go as far to say that it would take less time to install a clean version of the OS rather than uninstall each of HP’s preloaded craplets.

Software complaints aside, multitasking was incredibly snappy; running iTunes, TweetDeck, Skype, a number of tabs in Firefox all while a DVD played in the background was no challenge for the Core i7. Though not a likely scenario, playing a 1080p video in QuickTime with a DVD playing in HP’s MediaSmart software didn’t cause either of the videos to lag HP HSTNN-IB17 . As for gaming, our WoW gnome his new 1080p life, running around quite happily at 35fps. Of course, playing games meant the system once again got insanely hot — we simply couldn’t use the Envy on our lap while slaying orcs.

Performance comes with battery sacrifices, however. While writing this review in Google Docs with a few additional Firefox tabs open, the system lasted just under two hours on a charge HP 510 battery . That’s pretty abysmal for a larger laptop: the Core i7-equipped Dell Studio 17 gets close to three and a half, while the 15-Inch MacBook Pro gets just about 4 hours. And without the ability to switch off the discrete graphics, there are no battery saving measures. We’d be more forgiving if the power brick weren’t so damn large and heavy. It’s the kind of charger that belongs underneath a desk, rather than stretched across a bed. Sure, you can always get HP’s neatly designed nine-cell slice which fits right on the bottom of the laptop, but that will cost you an extra $125 bucks, and add additional weight and size.

Wrap up

We don’t mean to sound like a broken record, but we’re just as conflicted about the 15-inch Envy as we were about its 13-inch little brother. The multimedia and gaming experience blew us away — rarely do we see such performance out of a laptop this sleek and thin — but all that power results in incredibly high temperatures and below-average battery endurance. If you’re willing to put up with hot metal and less than stellar battery life for a pretty awesome multimedia experience HP 530 battery , the Envy 15 may be worth a try, but in the end it’s hard for us to recommend a laptop that actually became uncomfortable to use and hampered our everyday computing experience. Unfortunately for HP and us, these sorts of dealbreakers seem to be a common trend across its products these days.

3 Auto-Backup Solutions for Your Flash Drives

People are increasingly turning to flash drives, little pen-sized blocks which somehow manage to store a briefcase full of information, to carry their work or personal details around with Dell PC764 . While they’re satisfyingly convenient, their petite dimensions ironically contribute to the worst thing about them: flash drives are frustratingly easy to misplace.

Whether it’s your favourite playlist or sensitive information, here are a few auto-backup solutions to ensure that you never find yourself hanging in unexpected circumstances.

1. How to Auto-Backup with Windows

SyncToy is a native Microsoft Tool that allows you to backup information located on your storage mediums with a single click. It works by “pairing” two folders in different locations and updating the files in each so that they have the same content inside as Inspiron 6400 Battery .

It even comes with three options: updating the files from Left to Right without overwriting them, updating and overwriting them, or updating bi-directionally. By Inspiron 1420 Battery   itself, SyncToy doesn’t automatically backup your files, but it comes with a handy tutorial which teaches you how to use Window’s very own Task Scheduler to do exactly that.

2. How to Schedule your Auto-Backups

As far as freeware comes, GoodSync is among the best you can get. It makes an effort to be classy (has a nice interface), Dell GD761 is user-friendly, and does exactly what it says it will do. Like SyncToy, it makes use of the Left and Right concept to simplify the learning process.

Unlike SyncToy, GoodSync has a built-in synchronization setting which allows you to schedule when you’d like your backups to happen. This means that Latitude D620 Battery backs-up your flash drive automatically as long as it’s plugged into your computer at the specified time (set it to whenever you frequent your computer).

3. How to Easily Customize your Auto-Backups

If you’re prefer a more classic touch or just want to keep things simple, DSynchronize is a great tool with a clean interface which flattens the learning curve. All the Inspiron 640m Battery  appropriate checkboxes and buttons are where they’re supposed to be, and its simplicity stands out so much that you get the hang of it simply by “muddling” through, or experimenting by yourself.

Like GoodSync, it has a built-in timer, and even makes useful options like Autostart and Shutdown at the end available on the front page of Dell Inspiron E1405 Battery  so you don’t need to dig into the “Preferences” folder every time you want to tweak your…well, preferences.
