My guess would be the CMOS battery.  That's what makes it so your BIOS and other settings in ROM don't get lost when your laptop is powered off.

These are easy to replace in desktops, but laptops they can be a pain to get to depending on the laptop.

It is NOT the CMOS battery.

The info below may be useful for you.

You’re getting a 601 battery error.
You may need to replace the battery on your laptop.

First, go into device manager and uninstall the battery and restart the computer.

This will uninstall and reinstall the driver that controls the battery.

Do a hard reset.

Turn the computer off.
Remove the power cable and the battery.
Hold down the power button for 15 sec while booth power sources are removed.

This should reset the hardware in the computer.

Also here is a link that will walk you through the steps to test and calibrate the battery.
