This is the bin files, you must remove it and flash it with programer.

The one chip is placed near the intel chipset and the other near the kbc controller.

Here bios for Toshiba C850D and brd + schematic for DK10ABX-6050A2509701-MB-A02 and DK10FG-6050A2491301-MB-A02

I had toshiba satellite c850d which had no power or lights at all.. 0.2v to bios chip and nothing to EC aswell when plugged in and power button pressed.

hye rippergr this issue is about bios. please do reprograme the bios first with a good one. u must have eeprom programmer. but after u got 3v and 5v alw.
if u no 3v 5v dont flash but u need check where missing volt from schematic. for your reference please check couple of capacitor ,coil and mosfet in one place. so over there maybe 3v 5v section. just my suggestion
