Hey all,

I'm looking for schematics for Toshiba Satellite C70-B, motherboard AR10SU-6050A2631701-MB-A01. Any help would be appreciated.

Re: Toshiba C70-B charging troubles

I measured all 5 mosfets going to the IC at 200ohms mode. ACFET, RBFET, BATFET, LODRV and HIDRV all show open line between S&D, S&G and G&D, so no shorts there.

I also checked the diodes, capacitors and resistors around the area, no shorts to ground. Resistor values seem good, except the 2 R020 resistors showing 0.3Ohm instead of 20mOhm, but I don't really have precision equipment to measure those. Diode between REGN and PHASE also okay.

I have a Toshiba Satellite C70-B (Motherboard AR10SU-6050A2631701-MB-A01) with, I presume, issues with its charging circuit. I had a dead battery for a long while and had to keep the AC connected to be able to use it. I decided to finally replace the battery, but the replacements are not working. The amber power LED blinks repeatedly and the laptop refuses to start. I tried multiple replacement batteries, they all show the same behaviour.

Here is what I know so far:

AC only - OK. Power LED burns white and laptop boots.
AC + dead battery - OK. Power LED burns...
