1. Please turn off the power and disconnect the laptop, and then press and hold the computer power button to discharge and reset the motherboard.
2. Press the power button again after reset. If the problem persists, it is suspected that there is something wrong with the computer hardware. I suggest you take your computer to the local Lenovo service station for maintenance.
You can contact the service station staff to consult the price.
The following is the query link of Lenovo Service Station:/Lenovo/WSI/Station/ServiceStation/default.aspx.
For more detailed consultation, please contact Lenovo Service WeChat Engineer:
