Whenever I turn on APM (control panel - power options), Windows 2k says my laptop battery is critical, running at only 1% power It doesn't seem to detect plugging in a power source either - it still thinks it's running from the battery. However, my battery and power supply still seem to function. The battery charges as normal, and I get a good couple of hours useage out of it (as normal!) Any suggestions as to what might be causing this, and how it can be fixed?
