Re: Sony Vaio VPC-SB26FG cannot power on
Does anyone know how to change model/serial number in BIOS? Like a DMI tool?

Re: Sony Vaio VPC-SB26FG cannot power on
I swapped the motherboard and it's now working
. Thanks for pointing out the problem is on the MB. When you are swapping the board, make sure the dip switches match.

Re: Sony Vaio VPC-SB26FG cannot power on
I checked those pins in the photo before while connected to MB and they were all at 0 V but the connection to the battery had 3.3 V which tells me the power board seems fine but the MB is shorted somewhere.Leave a comment:

Re: Sony Vaio VPC-SB26FG cannot power on
I just ordered a new motherboard. I'll get back to you after replacing the board. Sony should recalled these boards. They definitely have poor voltage protection circuit, and unfortunately all components are integrated on the board. Basically you are swapping the whole computer lol. I am an EE but I don't have proper equipment to fix this board but the schematic is neat. Good job.
Could you post the link to the other forum?Last edited by chat007; 07-24-2013, 08:24 PM.Leave a comment:

Re: Sony Vaio VPC-SB26FG cannot power on
I have the same problem. It was working on the battery and I plugged the AC connector and it just died on me. I checked and the power board supplies 3.3 V to the battery. Which board should I replace? Motherboard or power?Leave a comment:
