PLEASE SUPPLY RELEVANT INFORMATION:
Operating System Version: Win98
Problem Application Name & Version:Power management
Problem Hardware Make & Model:Compaq Presario 1244
Error Messages:


The advance power management for my 1244 will not allow the Ni-MH battery to work properly. Sometimes I get an hour of battery and sometimes its good for about 6 minutes. I diabled all power management, including BIOS and booted to a command prompt and pulled the plug. The machine shut down in about 15 minutes. I removed the battery and tested it. The output was 10.75v - about right for a 9.6v battery under no load. I then connected a 12 volt lamp across the terminals and it has been lit now for 3 hours. Is there any way to update my power management or verify that the battery is either fully charged when the charging light goes out or fully discharged when the low battery alarm is triggered?

I recently ordered a new battery for it but am reluctant to use it when it arrives. Any help would be appreciated.

I would say that the battery is dying. I douct i thas anything to do with the power management. How old is the battery? Eventually when they get old they jsut don't work well anymore.

I'd give the new battery a try when it arrives and see if it makes any difference.
