F11-for-XO1.5 Release 10.1.1 Release Candidate 4- Hardware issue?

[Tiago Marques]

Hi all,

My XO-1.5 B2 just entered this state last night. The only difference is that
I was using it, writing e-mail, and then it rebooted itself. After that it
would no longer boot so I tried to run memtest. It crashed on the second
test with a random character on the right side of the screen and then it
would no longer boot, the screen just flashes.

Should I disassemble it to inspect it? I have some experience repairing
motherboards with cold solders, bad caps, etc.

Best regards,
Tiago
