When starting the motherboard, it says “CMOS checksum bad”, and it doesn’t even go into bios, what should I do?

Question

Iron

I didn’t use the motherboard for a very long time and then I was impatient to take a powerful computer for myself and in return to assemble the old one (there is a burnt percent) I assembled everything and run it and then it gives me what is in the photographs and I can’t even go into bios (motherboard asus p5pl2-e)

Answer 1

Change battery

Answer 2

Yelling about the usb device. Pull everything out of the usb ports, if it doesn't help, you'll probably have to reflash the bios via a usb flash drive (there are instructions on the internet)

Answer 3

kmos checksum usually due to problems with the battery, replace and set the correct time,
then reflash the bios, it would be desirable 8)
