Lenovo IdeaPad Z370 powering issue

[yobbgsm]

Hi Mates,

Any idea about this cranky machine? When power button is on, led light on power button lit then off. Looks like no power, so I disassemble and clean the board, re-applied thermal grease on the cpu. When I put it back it turns on but after pressing the power button at least 3 times. Laptop is ok when turned on, I don't find any issue. The only problem was the difficulty to turn it on again. Sometimes need to press the power button at least 6 to 10 times before it power up.

Any thoughts are greatly appreciated.

Thank you.
