QUOTE (battery @ Jul 10 2012, 04:22 PM)
I have an older Gateway MX6447 laptop. I have an interesting situation with the laptop charging light and the XP power indicator icon. The light on the front of the laptop shows that it is charging the battery. However, the icon just shows that it is on AC power. It will show charging, but only until it thinks the battery is 53%+/- full charge.
I know that this machine does have a battery refresh utility. Should I just run that? Or, should I just go ahead and by another Lenovo ThinkPad T520 Battery?
I am not sure if this is related or not, but I have noticed at times that the battery charging light, will turn off and will eventually turn back on. Not flashing, per se with any frequency, but still turning on and off. Does this mean that my ac adapter maybe it at its life span as well?
not sure if your laptop battery has a button on some do some don't.
fully charge the battery well as much of a charge as it will take.
remove the bettery from the laptop and look for the test buttom push and hold that button, it shoudl ight the leds to its power charge rate for example if its half charged only half the leds will light, continue holding the button in for another 5 to 10 seconds it should then go to test mode and no lights should show at all.
if it does light then the battery has faults the more lights the bigger the faults.
laptop battey's have a limited service life and they do with age not fully or discharge to the correct rate.
if your machine has a battery refresh utility i would run that.
but you can also clear memory effect from a battery the following way.
fully discharge the battery till the laptop go dead.
recharge the battery at the fastest rate, with a laptop that means charge but do not use the laptop charge for 14 hours no matter what the battery or laptop tells you.
start the laptop on the battery only and run till it goes fully dead again.
do this three times to clear a memory effect from a battery.
if that fails to improve things then you will have to think about a new battery.
with the lights doing that the battery is telling the charger its lost as little power and the laptop goes back in to charge mode.
then the control board in the battery say's fully charged and shuts down again.
its like a top up charge to keep it at 100% or what the battery thinks is 100%
