Compaq Prolinea 4/33, Compaq 102-System Board Failure

[Compgeke]

After a fairly good night I decided to power up my Compaq Prolinea 4/33, to get a nice 102-System Board Failure message. With a POST code reader connected it has error 92, which is a CMOS read\write test failure. After a few reboots and a new battery I still have the same 102 error.

Anyone have any advice or has this system passed it's time? If there's nothing that can be done, would it be possible that baking the motherboard in the oven for a couple minutes (similar to HP laptop fix) fix the problem if it's just solder?

Is the CMOS socketed, if so remove it and stick it back in.

On this only the BIOS chip is, and as far as I know the BIOS and CMOS aren't on the same chip (or are they...?).

It seems I brought this system back from the dead by...washing the motherboard.

First boot, it's complaining that it's missing everything as this here is literally just the power supply, motherboard, ISA riser card and a POST code reader.

Next thing to do is check the power supply fan, as I'm noticing it has a slight rattle to it.
