My best guess would be, under System Devices in Device Manager, "Microsoft Composite
Battery." However, you can't delete this one - just update the driver. You could
try that, and, if that doesn't change anything, do an SFC (system file check) on
the files identified as associated with that driver, which I believe are battc.sys
and compbatt.sys, both in c:\windows\system32\drivers.
