Vostro 420, CMOS Checksum error
Hello, everyone I need your advise.
Every Time I unplug my computer Dell Vostro 420 I got CMOS checksum error this happen after I clean up the computer using clean air from air compressor.
I've replaced the battery by a new one but still the same issue.
I bought another battery package and I've replace the battery 3 times but still the same issue.
