2. Investigation sequence and solutions.
1.Power adapter and battery.
First, check that the power adapter is plugged in properly and that the power plug is securely plugged into the power outlet. If there is no problem with the power adapter, try replacing the battery, as a drained battery or damaged battery may also cause the laptop to not turn on.
Workaround: Replace the power adapter or replace the battery.
2.External devices and interfaces.
Sometimes, problems with external devices or interfaces can also cause the laptop to not turn on. Disconnect all external devices (such as printers, mice, keyboards, etc.), and then try to turn them on again.
Solution: Disconnect the external device and turn it back on.
3.Residual static electricity is discharged.
Prolonged use of the laptop may result in the accumulation of static electricity, which can affect the normal booting of the computer. Press and hold the power button for about 30 seconds to release the residual static electricity from the notebook. After that, don't connect the battery, directly connect to the external power supply, wait for more than ten seconds, and then press the power button to turn it on.
Solution: Restart the computer after discharging the residual static electricity.
4.Motherboard and other hardware issues.
If none of the above methods can solve the problem, it may be caused by a short circuit in the motherboard, a loose wiring of the boot button, an abnormal switch, or other hardware problems. In this case, it is recommended to send the notebook to a professional repair center for inspection and repair.
Solution: Seek the help of professional technicians for repair.
3. Summary. When the Lenovo laptop presses the power button and does not respond, we can check the power adapter and battery, disconnect the external device, release residual static electricity, etc. If none of the above methods can solve the problem, it may be caused by a problem with the motherboard or other hardware, and it is recommended to send the laptop to a professional repair center for inspection and repair.
