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

[Yioryos Asprobounitis]

I did find some time open up mine.Nothing loose, burned or otherwise strange in the macro-inspection.
The microSD has the all the files and partitions and no errors (checked with an adapter in a Fedora machine). The XO-1.5 screen works fine on my XO-1.
Anything else I could check, or just fight my son for the other XO-1.5?   :-)

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

I doubt is related to the build but just in case...

I clean installed os205 on an a working XO-1.5 (#SHC00500908).

On first boot it froze about 4sec into the boot process, I think at "loading mass storage devices" or something relevant.

On hard reboot (with power button for 5sec) the backlight blinks for a split second but the screen stays dark. The power light comes on but not the processor and wifi lights. No chime either.

Reseting the EC by battery removal, get the familiar blinks but no change in behavior.

Is the XO-1.5 bricked?

Is there anything that I can do (replace micro-sd? make sure screen ribbon is fine? other?).

Any ideas

Thx
