I bought this ancient laptop (Toshiba T2000SX) on flea market. It uses two batteries (second one is for BIOS):
-pa8725u (14.4V 2.2AH NiMH) shows 0,45VDC
-XZ0072P09 (6V NiCad) shows 0VDC
They are dead, but I'd like to just try to recharge them. Of course there is no original AC power supply. So, can I use standard AC/DC converter (1000mA max)? Or maybe the 9V NiMh recharger? Should I just connect + to + , set voltage to 12VDC and let it charge for a while?
There is power connector on side of laptop, it says 18VDC. It has 4 pins but I don't have pinout.. if I obtain it, can I try it with 12V ATX PSU?
