i need help with my laptop is suddenly shut-off
when i use the laptop with AC charger plugged
it's never shut down , playing game burn the laptop with render ,working for hours
**************no problems ************************
the problem just happens when it's on battery
it's suddenly power off without any warning
and it's not power on until i wait like 5 minute
then it's power on
and when i put my hand on the usb plugs i feel little electricity shock
i hope it's not short to ground in the motherboard
i'm very tired from this problem

is there any fix to this problem plzzzzz ?
