Forgot to say: The motherboard is Aaeon HSB-811P. And the manual tells this: "The HSB-811P CMOS memory has an integral lithium battery backup for data retention. However, you will need to replace the complete unit when it runs down."
I assumed it was because the battery is soldered and really difficult to replace. But perhaps a motherboard gets destroyed if it looses the battery for a while?
Any help is truly appreciated, I don't normally mess around with this type of stuff. Do you normally replace soldered batteries or just throw the whole board when the battery runs out? Is there perhaps some actions required after the battery has been replaced?
Hi, my post was somehow deleted. Please let me know if it's inappropriate and was deleted by someone, if not there is some problem with forum engine.
Anyhow, I have a NLX motherboard that will not boot. It started to be a bit slow and needed a couple of tries before it finally booted. Later it would not boot at all either showing "CMOS checksum error" or black screen and a series of intermittent beeps.

Have replaced the BIOS battery which was completely drained but the issue is still the same. Any ideas what to do? Besides to replace the motherboard. I'll double check the PSU voltages tonight but have tried two different PSUs with the same result so I think there's something else.
Really grateful for any hints or help.
