AnyOne Know anything about batteries?

My battery needed to be charged since it had 40% charge left so i shut off the computer. I let it full charge. About an hour and a half later tried turning on the laptop and it would not turn on.

Try reinserting the battery. of nothing happens, then most likely you need to replace your battery as the circuit inside the battery might be fried already.

My Gateway laptop, NE56R1u, shuts down automatically when unplugged even though fully charged?


Dear Leslie,

I had the very same problem with a HP Pavillion DV4 laptop and the problem was inside the battery - one of its cells became defective and the charge did not last more than a few seconds - it also showed a 100% charged icon but the battery was depleted in seconds.

Before buying a brand new battery you could check with a friend that has a similar laptop if he/she can lend you his/her battery for a few minutes and check whether the laptop keeps on or not with that other battery. In the case it remains on, it is the battery for sure, and you will need to buy a replacement one. Check the link below, for one option.

Hope you may find this information useful!

Best regards,

Miguel L. Martins

How To Extend Your Laptop's Battery Life


Hi... This is Vikas Sharma From M/s Computer Solutions, Patiala - Punjab, India

Im Going to give you one good advice that if you want to make your laptops battery life batter and want that your battery should run and give proper backup then use the battery as much as possible and when laptop shown the message that battry low or less than 5% then charge it back full. do it atleast once in a week.

Acctually the purpose is that when you charge and discharge the battery full all the cells used and charged and discharged. when you charge your battery when it is having i.e. 40% or 30% etc. charging to full and then you use the battery upto i.e. 40% and again you charge it then the remaining 40% cells are not charged and discharged then they become useless and again and again this process dead the cells that are not in charging and discharging position. This is the one big reason for battery problem.

so I suggest that charge and discharge the battery for better results.

Thanks Take Care

Battery


This is the procedure for solving consider replacing your battery problem. Start by running the command prompt with administrator privileges. This will give the full control over the command prompt. There are those commands that can only be executed when you are using the command prompt with administrator privileges. Change the destination path showing on the command prompt to be set to C:\ then type the command POWER -ENERGY( to change destination path to C:\, type CD\ ). This command will make the computer scan the battery status and after 60 seconds, a report will be generated and saved in C:\. Simply open the energy report and scroll to check the battery information. Look for the design capacity and the last full charge, note the difference in this figures.
For my laptop, these were the details
Battery Information
Battery ID: Hewlett-PackardPrimary
Manufacturer: Hewlett-Packard
Chemistry: LION
Design Capacity: 88800
Last Full Charge: 36467

To remove the message consider replacing battery fully charge your laptop battery then unplug the charger to use the laptop on battery power. Use it until the laptop to automatically shut down. Still with the charger unplugged, power on the laptop again. Do this until the battery is totally empty. Now plug in your charger and charge the battery fully. Then perform the commands steps again by running the POWER -ENERGY command. Make sure you note the differences in the last full charge details. Continuously perform these steps until the figures in the last full charge are more than 40% of the design capacity.

I donot know what is wz my battery but it is show 100% but in real it is like 15% plus it is only stay like 15min while it is unplugged


Hello,

This is a sign that you need a new battery. If you can not get a new battery try calibrating the old one. Here's how:

1. Charge the batter to full. (I know you stated it is like 15% but charge it till it shows full.
2. Unplug the AC adapter and let the battery drain. (If your notebook shut down b/c of low battery, keep powering it on until it will not come on anymore.)
3. Once drained, charge it again to full power and repeat the process at number 2.
4. Finally, charge the battery again. This time it should be recalibrated to hold a full charge close to the factory setting.

Good Luck

I have got acer aspire 5520 the problam is when i charge my laptop it says the battery is full so i unplug charger then it stays on 99 percent then after about 20 mins it will go off and when i switch back...


it sounds like your laptop's battery has a reduced charge cycle. I recomend charging it to full then letting it die 3 -5 times. (to completely die means that it wont turn on at all. usually this takes a couple of times turning on to be sure.) this should reset the internal memory there by restoring its charge capacity.

Battery will not charge


I purchased a Genuine Dell Battery, It arrived dead with 1 test light on battery itself at 0% charged, It only lasted 2 mins before the laptop died running on battery, It doesn't charge the Dell battery at all The replacement battery only shows a 1% charge every 7 hours or so, nor do I have a yellow, green, orange light, The only time I get a light on the battery led is if i'm running on batteries and the battery level is below 10%, Its orange for low battery.
Thanks in advance to anyone who could help me.
