BIOS trying rebellion

Yup battery.... good luck with that

Some motherboards are simple just replace the 'coin' battery with an equal.

Others not so much, they opted for a rechargable nicad hard and soldered to the mobo.

If it is the battery, I'll be happy, it is a normal CR2035 in an open capsule. I test it later this afternoon.

Yea, its query the RTC to get the correct time and date, but if the batt is dead the clock don't work.

Earlier pentium series socket 7 mostly but some later models as well. I guess they all realized their folly as the simple failure of a battery could render the mobo useless. I have personally repaired a couple of such boards.

Of course mobo's have batteries not only to keep time but to keep the settings of the bios.

Wow I've never comed across such motherboards.
Even in my prehistoric Amstrad Pc 1512 (around 1987) the computer used standard alcaline batteries for bios.
