If the rechargeable 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 and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.

If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems.
1. The battery itself is dead.
2. the battery bay is loose
3. the battery itself is loose
Hope this helps...
It seems that the issues is with the battery itself, not the cppu.
To double check, you can do the following:
1. Disconnect adapter and run battery completely dead. 2. Reconnect adapter and let charge for at leasst 12 hours OR until battery displays 100% charge.
If it still won't charge to 100%, then you know for sure the battery is defective/worn out.. If you want to know more about this, look on wikipedia for: "Laptop Battery Lifespan" or "Laptop Battery Memory Charging".
But I'd say it's safe to assume that it's time for a new replacement battery for your Notebook PC.
