disconnect all external devices from laptop, including charger ,USB mouse . let battery power completely drains off.
now press and hold power button for 120 seconds and release the key.
now connect charger for30- minutes charge it .then switch on the laptop, immediately press escape key , select enter setup, reset bios settings to default and then save and exit.
As reference information given to you by others, If you disconnect all external devices from your laptop, plug in the power supply and charge for 20~30 minutes and it still can not boot. I would like to suggest you to bring back your laptop to our service center.
