Seems like a hardware failure indeed.
Just to be sure on the "time" battery, you could try and remove the main battery while power is unplugged and wait an hour.
If the clock is still on time the time battery should be OK.
Anywhoo, did you try Deepthought's idea to boot from a USB key with a live Linux Lite? Maybe there's a little life left in the patient
