I have an HP Compaq nc6400 running Windows 7. The battery shows Fully Charged (100%). When I try to use it without the AC power it runs for less than a minute and shuts down.

I did find the Power Options and changed the Critical Battery Level and Low Battery Level. They were 98 and 99 percent respectively. I changed them to 10 and 20 percent respectively but that did not have any affect.

In Devices, Battery - I had two Microsoft ACPI-Compliant Control Method Battery entries. Something I read told me there would be three entries under Batteries, one of them the Microsoft ACPI-Compliant Control Method Battery. I uninstalled both of them. When I restarted the computer the two entries were back.

I suspect the battery is shot and I don't have another to try. I just want to know if there is anything else I can try before I buy another battery. It just puzzles me that it shows 100% rather than a red x through the battery.

Thanks for your help
