lenovo laptop battery Instructions
First, note that the details of the using.
In the actual use of the process, many of the details have not been noted, has affected the life of your lenovo battery. For example when the AC-powered laptop at the state shutdown, waiting for the power indicator light and the bottom of the screen all the lights off after the exchange with the plug pulled (not later than 5 seconds). After the lights go out because the power supply board are still working, this time will begin to pull the plug on the battery, thereby accelerating the battery more quickly fell to the charging power to set the starting value, thereby reducing the battery charge with the cycle, affecting the battery's life.
In addition, when using AC power supply, the adapter plug the input plug and output plug (unload) the correct sequence of operations is: First the AC adapter's output plug into the power jack plug, and then plug into the input plug power outlet; and should be removed when the input should first unplug the plug, then pull the plug then the output. This will prevent the adapter has been damaged in a no-load state.
Second, in-use maintenance and storage.
1, the battery charge times by their limited life span, so there are places in which AC power, they should make full use of AC power to minimize the number of thinkpad x40 battery charging to extend battery life;
2, when the electricity is 3% to 5%, it is timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge and damage to the battery, charging the machine can be in any state, side by side rechargeable battery also will not hurt ;
3, power is not fully depleted before (ie electricity at 5 ~ 100%), not to recharge the thinkpad x40 battery, otherwise they will reduce the charge to increase with cycle number of charge cycles and shorten the battery life;
4, if the battery a long time (several months) do not, remove the saved backup from the machine; if the battery a long time unused, it should be set to 30% of electricity consumption to 50% in storage; Do not put the battery temperature and cold environment, the battery performance will be temporarily reduced. Should be at standby mode to save battery life and storage of the state placed in places of lower temperature for the thinkpad x40 battery, the best temperature range is about 10 ~ 20 degrees Celsius.
Third, on the activation of the battery deal.
Just purchased a new Thinkpad batteries to activate processing, ie 100% charge and discharge, in fact, a random Thinkpad help to say "re-engineering of your thinkpad x41 battery every month, that your battery is 3% or less, which will increase your battery capacity ", is intended to adjust the battery management chip and charge control chips in the normal value of each register. Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample thinkpad x41 battery power, and if the chip has not been opportunity to once again read out the full curve, calculated results can also be allowed.Therefore, the need to calibrate the deep charge-discharge.
Extend Your lenovo Laptop Battery Life With BatteryCare
How many of you out there know about proper lenovo laptop battery care? There are so many urban legends and myths regarding batteries that it is hard to know what is real and what is not.
MakeUseOf had an article 20 Ways To Increase Laptop’s Battery Life which mentioned a number of useful tips. This time we introduce to a rather different app called BatteryCare which can help you understand the ways of battery guruness….is that a word? Probably not but hey it sounds good!
Way back when, it was very bad to leave your laptop plugged in and charging after the battery was charged. Nowadays this is not the case because the computer switches to a trickle charging mode when the battery hits 100%. BatteryCare not only gives you a glimpse at a glance of your available power including the time you have left it also does some neat tricks that can help you extend your thinkpad t60 battery life.
After downloading and installing this small application you will have a new system tray icon. Mine is all the way to the left. It tells me that my thinkpad t60 battery is 95% charged and can operate for 2 hours and 36 minutes at the current rate. This is a HUGE improvement over the normal battery meter you see in the middle of my system tray.
The first trick it can do is change your power settings to a different profile depending on if you are plugged into power or not. These profiles can turn down your screen’s brightness or turn off Bluetooth.
To setup a power profile you can visit your Power Options in your Windows control panel. Once you have them set up or you decide to use the built in ones, click on the BatteryCare icon and open the application. You will see the screen below.
Next up, hit the options button and then Power Plans. Simply check the box that says Automatically select Power Plans. Then choose the plans you want to switch to when you are on battery or AC power. When you are done click accept - yes, it is that easy!
While we are in the options let’s see what other choices we have. Under advanced options you can be notified when a Full Discharge is necessary to improve the performance of your thinkpad t400 battery and extend the laptop battery life. The program tells this by noting how many discharges your machine has had since it started running. You can manually adjust this number if you are not running this against a new battery, do this by setting the Discharge cycles count manual adjustment number at the bottom. I set mine to three. When you reach your set number you will be prompted to fully discharge your battery.
By clicking on the detailed information tab you can see the lenovo thinkpad t60 battery manufacturer as well as designed capacity and total capacity, this can tell you if your battery has degraded. Thankfully mine is fine.
Even after leaving the app running for several hours some of my numbers were at zero but for the sheer power of changing profiles on the fly and the detailed battery meter this app is AWESOME! Thanks guys keep up the great work. Their website also has some awesome information on debunking the lenovo laptop battery myths.
We’ve also discussed two alternatives to the Windows laptop battery meter which is something else you can consider.
Dell Inspiron E1505 laptop Batteries problem
I bought the Dell Inspiron E1505 about two years ago. Like so many of the others who bought this laptop, my Type gd761 , KD476 , 85Wh battery died just after the one year mark. The problem started when the battery light began flashing. The battery has a usage button on it which indicated that the battery was fully charged, however, every time I put the battery in the laptop, the light started to flash again. I found dozens of blogs and tech sites like this one where Dell users have voiced the same issues with this computer and its battery. (Just enter, "Problem with Dell Inspiron E1505 Battery" into your browser to see what I mean) All Dell will offer as a solution is to tell me to buy a new replacement battery.So I bought a new one on http://laptopsbattery.us/dell-inspiron-e1505-battery.htm
This battery started off incredibly strong, kept my Core2Duo Inspiron E1505 going for a solid 4-5 hours per charge, enough time for me not to need the charger as I studied on campus.
This Dell Inspiron E1505 battery--9 Cell Replacement Battery features lithium technology, which ensures maximum battery life and maximum power. It also features no memory effect that lets you recharge partially drained batteries without reducing performance.
The overall performance of this laptop was marginal at best, despite what anyone else thinks of it. My older Inspiron 1100 is a much better laptop and has never had any issues with it's battery. I was enticed to buy the more expensive battery when I got the E1505 because the Dell wen site said it would last longer. Obviously, that is not true. Dell Customer Service will not take ownership of the problem that I am many others have had with this laptop. I've bought five computers from Dell in the past seven years or so. The E1505 was the latest purchase. My older Dell computers all work much better than the E1505. Personally, the E1505 is a useless piece of junk to me, if I cannot use it as a portable computer. Instead, it remains landlocked to a wall outlet if I want to use it.every year for a new inspiron E1505 battery. I either expected my money back, a free battery or a comparable replacement for the E1505, any of which I know I will never receive from Dell. They don't really listen to their customers. I used to be a big Dell supporter, but not any longer. Dell sucks as far as i am concerned! My next system will come from HP. I won't buy anymore Dell products and I'd suggest anyone else to avoid buying a Dell computer unless you also want a headache, or you enjoy being ignored by Dell when you have a problem with their products.

Dell inspiron E1505 laptop Review
Dell Inspiron e1505 is 15.4" widescreen notebook featuring the impressive new Intel Core Duo CPU. A virtually identical Inspiron 6400 is available through their business site. Outside it looks the Inspijust likeron 6000 it replaces, but the new hardware inside makes for impressive performance. In traditional Dell style, the inspiron E1505 is well rounded, quite customizable and available at a competitive price, but doesn't offer anything radical.
The Dell Inspiron E1505 is powered by an Intel Core 2 Duo T5500 processor,li-ion dell e1505 battery, 1GB of RAM (MAX 2GB), 80GB Hard drive, ATI Mobility Radeon X1300. It comes with also 8X DVD+/-RW dual layer burner, 15.4-inch LCD screen with a resolution of 1280×800, WiFi 802.11b/g and a 5-in-1 card reader. It gets 4 USB 2.0, a FireWire, S-Video, VGA, Ethernet ports.
Inspiron E1505 Laptop Description:
v.92 56Kbps Modem, 10/100 Ethernet and 802.11b/g Wireless
Screen:
I chose the highest screen option which is WSXGA+ (1680x1050) Ultrasharp with TrueLife (glossy). The Ultrasharp screen is listed at having significantly higher viewing angle, higher resolution, and slightly higher brightness. The wide viewing angle was my main interest. However, it seems about on par with most other mid- to high-end notebooks. It makes me think the lower screen options would be disappointing.
The screen is very sharp with nice saturated colors and high contrast. It is close, but not quite as bright as others I have reviewed. There is some light leakage near the bottom of the screen.
Processor and Performance
My Photoshop tests reveal that the Core Duo is almost exactly TWICE as fast as a single core Pentium M of the same clock speed for common tasks photographers do. Video editing and other high end tasks display similar results.longer battery life,dell e1505 battery,give your laptop more power.
Below is the popular Super Pi benchmark result for calculating Pi to 2 million digits. This program only uses ONE of the CPU cores, so I could do other tasks and barely affect the benchmark score.
Battery:
With the smaller option 6 cell battery and a powerful new processor, I didn't have very high hopes for battery life. However, the Dell inspiron e1505 battery lasted longer than expected. At maximum brightness, it played a DVD for 2 hours and 30 minutes. Under normal light tasks, with WiFi on and almost maximum brightness, the battery lasted almost three hours. Dimming the screen all the way and shutting wireless off squeezed almost 4 hours of total battery life. I could burn the battery in about 90 minutes or less if I really tried. Gaming would likely burn it this fast.
A bigger laptop battery might be a better choice than two batteries. Lithium-Ion cells wear out even if you don't use them.

How to increase your Dell laptop battery life time
Dell Latitude D830 battery life time can be increased or decreased depending on the applications and tasks that you have your laptop doing. This article will tell you how to increase your Dell Latitude D830 battery life time.
Dell Latitude D830 battery life time can be increased or decreased depending on the applications and tasks that you have your laptop doing. For example, if you are playing a DVD movie, much power is being used, shorter time will your Dell Latitude D830 battery be used. If you are burning a CD-R/CD-RW or playing a full screen 3D video game, much power is being used. All these things take more power and in effect lessen the amount of time that you have in “portable” mode.
It is best to try to plug the laptop into the wall if possible in these situations. Remember that you can also get car power adapters for your laptop; this will charge your Dell Latitude D830 battery and power your laptop while you are on the road. Programs that take little power (giving you longer laptop battery life) include word processing programs like Microsoft Word or Corel Word Perfect, Microsoft Excel, Microsoft Access, Outlook Express, Internet Explorer, AOL, CompuServe, or any similar programs. Even the colors displayed on your screen can affect your Dell Latitude D830 battery life. Lighter colors take more power to produce. External connections such as USB Mice, USB Scanners, Memory Cards, Zip Drives, etc. all take more power from your precious Dell battery life. Keep these things in mind when power is of the essence.
Here are some tips to extend the life of your laptop battery:
1. Power down the display
Lowering the brightness may give you as much as an extra hour of runtime. And to increase even more the lifetime of your laptop battery lower the screen resolution and color depth. This will decrease the workload on the GPU, thus extending the battery runtime.
To change this settings follow the steps below:
2. Turn off unused devices
Many new notebooks provide a hard-wired On/Off switch for the Wi-Fi radio for this reason.
To save even more power go to the Control Panel, select System-->Hardware-->Device Manager, and disable the following items: Ethernet adapter, infrared transceiver, and Bluetooth radio . You should do this beacause having Bluetooth enabled and not using it actually consumes quite a bit of power.
3. Decrease hard drive activity
Defragmenting your hard drive regularly will decrease the frecuency with which your hard disk has to spin, therefore the dell inspiron E1505 battery will last longer. This is due to the fact that defragmentation optimizes the placement of the data on the drive and when a program makes a request for certain data it can be found more quickly.
To defragment your hard disk follow the steps in this article.
Another way to decrease hard drive activity is to set your paging file to a fix value, and this value should be around 1.5 times the amount the RAM you have installed on your computer.
To set the paging file go to the Control Panel and click through System -> Advanced -> Performance Settings -> Advanced -> Virtual Memory Change.
4. Disable startup items
Startup items are programs that load into memory every time Windows boots up and cause other open applications to spill over virtual memory and adds to the CPU load, shortening battery runtime. Here is how to remove some of them that are not necessary.
5. Condition the battery
Battery memory is where the dell inspiron b120 battery becomes conditioned to run for less time than it is designed to run. Say for example, you run your computer on latitude d830 battery for an hour and then you plug it back in to let it recharge. The battery will become conditioned to run only an hour before it runs out of juice.
To correct Battery Memory problems, you must completely drain the dell battery and recharge it. To completely drain your dell xps m1330 battery, you must go into your Windows Control Panel and select Power. Then you must turn Power Management Off. Next, you must go into your BIOS and make sure that if there is a power management setting there, that you turn it off as well. In most cases, once you are inside the BIOS, you will highlight Power Management and press Enter. Then locate the item Hibernation at Critical Battery, and by using the Minus sign, change the setting to Off. Once these steps have been completed, then use your Escape key to return to the top level menu, and select Save Settings and Exit.
Once you have completed turning off the power management in both the BIOS and the Operating System, you must unplug the computer, turn the computer on and let it run until it completely runs out of electricity. Then you should charge the battery for 12 hours. At the end of the charging cycle, then run the computer again until the inspiron e1505 battery is dead, and then charge the battery for 12 more hours. You should repeat this process four times, before returning the computer to its original power management settings.
A great little tip to keep in mind is that if you do keep your laptop plugged in for an extensive period of time REMOVE the battery. Let it discharge and give it a break. This will extend your battery life quite a bit.
Another way to condition your battery is to keep it cool. It's best to use (and especially charge) your batteries at room temperatures. Extreme conditions can drain your battery quickly.
