here is what the store IT help line suggested.
Greetings Elizabeth,
I understand you have a problem with your computer. If you could enter the BIOS right away and then press F10 to save your changes and exit. See if that might resolve the problem, if not you might have a bad battery on the motherboard, or another problem with the motherboard itself.
If you still have trouble after saving the settings, I would recommend returning the motherboard for another one.
Thank You,
