I have a laptop which has LX6 motherboard with following symptoms

When I plugged Ac adapter adapter LED blinked few times and on ( it indicates power). if i put battery then its turn into orange which means charging the battery.
PU4 -3.3v and 5v are ok
CN4-
4th pin NBSWON1# 0v
3rd pin LID_EC# 3.3v

I flashed Main and EC BIOS but nothing. What should I do next..?

Нужны замеры. U7(EC) 95, 6, 16 пины. Генерация на кварцах Y4 и Y5.

Если так при не нажатой кнопке, то вариантов не много:
оборван резистор R292.
замкнута кнопка power.
неисправен EC контроллер.

I translate post from orbit to you:

If power switch button not pressed (no short cut):
- R292 not connected (defective)
- EC controller defective
- check resistance from power switch to ground
