laptop Acer swift SF314-41 Repair

[OvO]

my laptop has a weird problem. it has a power on issue.
Once the laptop has been powered on, it can restart/ wake just fine on battery power or Adapter, ONLY If i have not closed the LID/LCD even once.
If i have closed the LID /LCD (even momentarily). it will not power-on/ wake-up on battery power no matter the battery percentage.

but once i open the LID and connect it to the adapter (even momentarily) it will wake up gain and I wont experience any issues till i close the LCD.

i do not know where to look for repair.

The close screen function is powered from two sides, battery and charger, now battery side is not working.
Probably so that some signal is pulled down and should be popping back up when the lid opens.

Can also be just a setup.
When lid is closed the machine goes to too deep sleep.
Or setting is so that stay off when power goes out and it's not functioning as expected.
