Hi

I can't say this will work but i remember somewhere i read try replacing

the onboard battery and see if you get the error message after that.

This link might help also.

Good Luck

I took out the button Cell Battery and tested it with my volt meter, which read around 3 Volts. I then put it back into the motherboard. After that i loaded up the Dell Diagnostics again, and ran the same test. All test passed. Thank you!
