Pls need your assistance, I have a company laptop that won't open, when i plugged in the charger, the power button will blink 3x, and when I try to press and hold the power button while the charger were plugged in, it only blinks 3x, and also try unplugged the charger, it doesn't do anything when i press and hold the power button.

Already tried closing and opening the lid multiple times but still unsuccessful


And this laptop is non removable battery, and no hole for reset as well

P.s. it already happened before and i was able to open for over an hour, patiently pressing the power button and closing/open the lid.

Hope you can help
