i forget to power off my laptop when i sleep.after i wake up i saw my laptop totally black and cannot open the screen
It should be a charging problem.Connect charging pin with laptop.If charging will work you will see a blinking charging light.After 2 hrs it will work for sure.Hope it will work
It is in sleep mode Touch the touchpad. If problem didn't get solved remove the battery of your laptop. Then keep pressing the power button of your laptop for 1min. Then insert the battery and press the power button normally
