The Compbatt service is a kernel driver. If the Compbatt fails to load or initialize, the error is logged and the computer attempts to restart with the LastKnownGood configuration. If the LastKnownGood configuration fails, Windows 7 startup also fails, and the boot process halts with a Stop error. If you disable this service, Windows 7 will fail to start. Do NOT change this service startup configuration if your computer is working.
