And after you changed the battery and reset date and time, did you <u>Save</u> and Exit?
And note following Alzeimer to emphasise, you only momentarily (a second or two) move that jumper to short the two pins, then you are supposed to move it back. Shorting the two pins removes all power from the CMOS memory module, thus resetting any custom settings the CMOS module had saved for the BIOS.
Hello Sir and Alzeimer, first of all thanks for the input.
I'm pretty use I've done everything correctly, have even tried a different power supply thinking it might be defective but no go. Once reset has been done I of course go back into the BIOS and save the setting, on next power down the CMOS is lost again.
