I'm replacing the CMOS battery on a newly acquired Toshiba Tecra 550CDT. I see it has two batteries on the motherboard, a 2.4v 30mhah battery I think is the CMOS battery and seems readily available on eBay, the second is a 7.2v 30mah battery I'm not sure what it does? It seems I saw something somewhere it's possibly for sleep, but can't find that now. I assume it's safe to leave it unplugged.
I also notice it seems like the pins and connector has a little bit of what I assume is green corrosion that has made it up the wires. I'll clean it up, some vinegar and alcohol?
