    • Check the fit between the tab on the battery and the screw standoff on the chassis closest to the CMOS battery.

    • There should be almost no gap between the battery tab and the standoff. The clearance circled in green is acceptable. The clearance circled in red is not acceptable.

    • If there is too large of a gap, screwing in the main battery will bend it and put stress on it, which could cause damage.
