Hearty greetings to everyone, trust you all are doing excellently well.
Please, I have the above problem, the laptop turned on after the switch was activated but it will turns off in less than 2 seconds.

The things i have done:

2. Not a power switch problem, it behaves the same without the switch ...06-10-2024, 05:05 AM -

The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this... -
Had one of these come in for repair with a blown battery and a WiFi issue, battery has been replaced with genuine battery (twice) and won't take a charge works fine on AC, WiFi issue gone away. Looking for a schematic so I can trace the charger circuit UM562F is only one I can find, this is the 562AI model.Had a unit come in for repair — 562AI model — with a blown battery and WiFi issue. WiFi fault has cleared, but battery won’t charge despite replacing it twice with genuine parts. Device operates fine on AC power. Suspect charger circuit fault. Only schematic I’ve found so far is for...06-26-2025, 02:41 PM -
