1. Unplug the external equipment and self-upgrading hardware equipment of the machine to eliminate the influence of external equipment and upgrading equipment;
2. Check the indication of power indicator and boot indicator.
A. If the indicator light is not on, it is recommended that you check whether the power adapter or battery has good power supply or sufficient power. You can use the same type of power adapter or battery to replace and test it separately to eliminate the power supply problem.
B. If the indicator light is on, I suggest you switch videos with Fn F4 to see if the problems you encounter can be solved. If the problem cannot be solved after switching, it is recommended that you turn off the power supply, remove the power adapter, battery and external equipment, and leave it for about half an hour before turning it on. If the problem still exists, you can contact Gold Service Center for on-site hardware maintenance.
