Toshiba Equium A60 - Refuses to power up/detect power after bad BIOS flash.
Posted on 2006-05-09
A friend of mine had this laptop and his friend attempted to update the BIOS and when they finished the machine is dead. He said that something went wrong during the flash.
I was expecting that there would be something on the display even if the BIOS is screwed. None of the lights, light up to indicate the machine is aware that it has power. I tested the power supply with a DMM and it is putting out 19.4~ V which is good and healthy. Then I got the screen off and checked at the motherboard to see if it has power at it and it does but still no indication that it has power and does not attempt to start.
I had the motherboard out to see if maybe there was a jumper to reset the system after a problem like this or a battery backing the BIOS or some way to reset the board. There were no jumpers but there is a battery. The battery is soldered to the board and is reading 3V. I desoldered the battery and kept it off for a few minutes then soldered it back on, reassembled the system and its still "Dead". Ive fixed laptops many times before, replaced parts, etc.. and ive dealt with difficult BIOS situations such as "The Award BIOS boot block" and others but I really dont know where to go with this system. I couldnt see any signs of burnout/damage on the board.
The machine is in immaculate condition and barely used, I cant understand why it wont start. Any ideas?
