If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.
Thanks Sir,
But the battery is just 4 months old & none of the factors listed by yourself confirm to its behaviour. Moreover having already mentioned, the HP battery check tool confirms it to be perfectly ok.
Pls re-analayze the issue & oblige.
Does the battery show 100% charge and how long does it take to charge up from a near flat battery condition?
When you run the laptop from a fully charged battery how long before you run out of battery power?
If the time taken to charge and discharge the battery is short then the battery is probably faulty even though it is not old.
this may be the problem from the cooling faun,pls cheek the faun rotation is working properly.
why post to 2011, ?
fans not faun
check not cheek
his battery is bad, 7 years ago
and failed 5 more times since, due to excessive deep cycles.

Thanks once again Sir & Sorry for reverting late being out of town.
Yes,it shows 100% charge & it takes about 45m-1hr to get fully charged. Further, the question of running out of battery doesn't arise because it turns off abruptly especially when the ac adaptor is plugged out. thereafter even if the battery is above 90% charge, it doesn't start up. Moreover, power drain has already been tried for your reference.
