A Please take out the lithium battery (some models can't take out the battery, please skip this step) and use the transformer to supply power directly.
B please remove all external devices, including USB/ memory card/network cable /HDMI, etc.
C. Did you expand the hard disk or memory before the problem occurred? If yes, please restore the factory default status first.
Solution 2:
The power indicator light is not on, which may be that the transformer can't supply power or the main components are abnormal and can't be connected.
A. Please confirm the transformer connector, as shown in the figure below, whether the power cord end/socket end/computer end is loose, or try to replace the socket.
B please check whether the transformer wire is damaged. if it is damaged, please replace the transformer for testing.
C. please refer to the solution 1 for troubleshooting.
