I started noticing my battery life span dimmishing months ago. It got to the point that the battery would not charge anymore. I ordered a new battery on thanksgiving day and it didn't work. The new battery had 60 minutes and it was counting down. The charge would hold if the AC cord was plugged, but it would not charge. Battery went down to zero % and I returned it thinking the battery was defective. I now have the new one and it's doing the same thing. The icon shows it's charging, but it will not increase the percentage at all with the old, the first or last replacement. I have to have the AC cord plugged in, in order for it to work.

Even with the advancements in portable laptop batteries, they still only have a specific life span. The battery will charge the entire time you have it plugged in and these charging times are called cycles. Even the best battery you can by will only perform optimally over a certain number of recharge cycles. When you start noticing that you no longer have the same amount of time on a full charge, your battery is on it's way to needing replaced. Some suggest that you allow the battery to run down as often as possible to extend the battery's life, but with today's battery, often won't make a difference.
You will need to buy a new battery, there is no way old one will be OK. To see if it works, remove battery, and use wall adapter ONLY, PC should work fine. If not maybe Flat CMOS, replace, If replace and still NO go.must be bad motherboard (maybe try charge battery 5 hours left alone)
Remove battery and ac ADAPTER from the laptop
Press and Hold the power button for 40 sec(No battery and No Power chord)
Connect the battery back to laptop
turn on your computer,
Login to windows
check the battey backup
Connect the Adapter back and check the the battery life
sir/mam you`re battery pack is need to re-pack or change the Battery pack.if you want to safe and long life Battery Pack if you use the unit inside youre house use only a charger then remove the battery pack from unit do not use both supply,like a battery with charger.if baterry full only battery,if you charge the battery charge only..

When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.
Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.
Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.
Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.
It could be that your battery is defective/worn out. If the computer just shuts off immediately (doesnt try to hibernate/standby) then you're likely looking at replacing the battery. They can suddenly do things like this if a cell shorts out in the battery or due to common wear. But first, here are a couple of things you can try.
1. Try reseating the battery (pull it out and put it back in). Sometimes something that simple can fix the problem. 2. Try to calibrate the battery. Your computer may come with instructions on how to do this, but if not you can do it manually. Turn the computer on but go into BIOS (press F10 at the compaq logo screen). Don't load your operating system Unplug your computer. If it turns off at this point, your battery is already toasted. Replace it. If the computer keeps running, let it go until it finally shuts off due to battery drain. Then plug it back in and let it recharge completely. This will let the microchip in the battery learn its charge potential and may allow you to get more life out of it.
Note: Calibrating these batteries is good practice but it shouldn't be done very often. If your calibration doesn't work after 1 or 2 tries, you probably still are looking at a dead battery.
