My laptop battery won't hold the charge.

Is the battery a genuine Dell battery? 3rd party batteries can be high quality or crap, just depends on the maker. Regardless, when you attempt to charge it, does it at least take a charge even though it won\'t hold it? Or does the battery refuse to accept a charge at all? When you plug in your laptop, does the charge light come on? Does the the battery level icon on the lower-right corner of the screen show it\'s plugged in? I know, lots of questions.

If your battery does not hold charge, and you don't want to buy a replacement, then there is not much can do other than to keep using your laptop with the charger. All batteries have a time life span.

On what kind of PC Laptop?

It most likely needs a new battery, but you could try giving the battery a full charge first:

1. Power off the laptop and disconnect the power adapter.
2. Re-seat the battery (remove/reinsert)
3. Reconnect the power adapter and let it charge overnight. (6 hr+)
4. Disconnect the power adapter.
5. Power on the laptop (run under battery power only)

If it doesn't boot up and shuts down immediately, it's probably time to see about a replacement battery.

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.

a problem with the battery or a charger.

Battery could be dead and won't hold another charge. Batteries only last for so long until you have to replace them. If you laptop is ok with the AC Adapter & Power Cord meaning it boots and allows you to work in windows, then the battery is definitely dead.

Will the laptop power on with the AC Adapter and Power Cord plugged in? If so, the battery is probably dead and won't hold a charge. Batteries don't last forever.
