toshiba X75 laptop.
Wont boot. Black screen. From reading around i have a problem where i have no post. It was intermittently not booting until it doesnt now.
Tried:
Removed HD, RAM, dvd drive, wifi adapter.. still no boot.
Tried all the tricks with taking battery out, holding power button, etc.
tried warming up the case really hot with a hairdryer. Was considering putting it in the fridge to see if the opposite is my issue. Unsoldered pins etc.
Think I’m narrowing it down to motherboard.
Sometimes i get a fan, most times i dont. If i get a fan it will boot, every now and again.
any other way to diagnose motherboard? I dont have an external monitor, but conisdering that sometimes it boots up fine im taking the monitor to be fine.
Just practically taken the motherboard out to get the serial number, sonim happy to swap it, if i can get a confirmation its that.
Interestingly after i took a lot of bits off it and started it offered me f2 to get to bios. Did that. Reset system time, booted. Now wont again.
How do I verify the power supply brick is supplying the right juice?
If I manage to get a boot should I try to flash bios? Or would that compromise swapping motherboards if it gets to that.
Thanks.
