Step 3.
Took out the screen and checked it to a secondary Gen 2 i have, screen works like a charm.

Hi all,
As the title suggests, how can I be sure that my EC chip is really dead?

There is a 3V3 on a keyboard... -

Here is what happened:
At one point i was fixing a setting on the laptop to make the laptop properly recognize the NVMe drive i put in months ago. All worked until all of a sudden the computer blue screened.

Hi there, I need help with the diagnostic on this board (NM-D563 Rev2.0).
I could not find schematics nor boardview for it.
The laptop was working, playing game when it suddenly crashed. Thermal paste is good and fans are clean. Since then, when power gets plugged in the laptop tries to come on (led lights light up, on off button lights up CPU and GPU warm up) for a minute or so before shutting down. No Display, no beeps no flashing led
There's no liquid damage. I've checked the board under the microscope and can't find any damaged components. I've checked...06-24-2025, 04:26 AM
