    Why bother?

    Most, are CR3032's, please give us the batt model.

    They are cheap to replace, if you are questioning it's performance -> Replace it and be done.

    I think it is VBAT. The voltages look OK.

    The question is - when the computer is turned on and powered up (and, heck, even if there is just power supplied to the PSU) - is VBAT power actually supplied by the battery, or is it supplied by the PSU?

    >>Could you please suggest a better test? I have no issues wish it now and time would begin to be off bit if it was dying. I tried to remove it when i was hanging hard drives but dell has a maverick spring type clip and I tried pushing it every way. It is the positive part of continuity on the board so I did not want to break it.

    I don't know if VBAT is supplied by the PSU when the PSU has power or not - so the VBAT reading may very well be the battery itself, I don't know. The only way to test that would be to run the software test again with the battery removed and see if VBAT still shows 3.2v. The only other way I know to check the batteru for sure would be to remove it and test it with a voltmeter and, as stated, if you are going to do that, might just as well replace it with a new one.

    I understand and thank you.
