I have an HP Pavilion DM1-3101ea laptop with an integrated AMD E-350 APU. Basically the same as DM1Z, if it is of any help. I have Ubuntu 12.04 on it. The problem appeared as follows: i tried to send it to sleep mode but it didn't work. After a short period of time the fan started spinning up. At this point i turned it off by holding the power button.
I came back to it after a while and, after i turned it on, I was brought to the following state: the fan and HDD spin up, completely blank screen, as in no power goes up to it, not even the LED backlight. The Caps Lock LED flashes 5 times, and the HP blink codes page states that this is "General system board failure". To be noted that they have different codes for CPU, GPU and BIOS failure.
What I have tried:
-
resetting the BIOS by disconnecting the BIOS battery and holding the power button for 30 seconds
-
booting it up with no HDD, WiFi card
-
booting it up with an Ubuntu Live USB stick and external VGA monitor + same & disconnected LVDS cable
-
booting it up with disconnected LVDS cable, no Live USB, no HDD and no WiFi
-
swapping around the RAM modules and slots
What I got was the same blink code.
Any ideas as to what might help?

The only thing you haven't tried is maybe trying a different A/C adapter. I doubt it would make any difference. I'd say you've eliminated everything except the system board.
Replace the system board.
