low voltage POST only means battery problems?
No doubt the watch battery on the motherboard long since lost its juice. However, I'm not quite sure what error I saw on boot, I think it was before POST and I think it mentioned low voltage . A quick search of dmesg shows nothing with regards to voltage , so it was probably before POST . I'll do what's feasible with regards to looking at the power supply, but any suggestions? It's a mature PC (meaning quite ancient with a retail value of zero or fewer dollars).
