Try power:
Plug the PC into power first. If that does not work, wait for 5 to 10 minutes in case the battery needs to charge to a certain level.
Check the power, adapter, and cables:
- Verify that the AC power adapter is correct for the system.
- Plug the AC adapter into the computer and a power outlet. If the computer has a power indicator light, check if the light comes on.
- Do not use a power bar.
- Make sure the cable is securely plugged in.
- Try a different cable.
- Try a different outlet.
- Does the PC make a sound (for example, fan noise)? If so, check light settings and increase the brightness level.
If the laptop still does not power on, try a power drain:
- Unplug the power and disconnect external devices.
- Remove the battery if the battery is removable.
- For laptops with an internal battery (not removable), use the pin hole reset.
Laptops with an internal battery may have an emergency pin hole reset button on the bottom cover (see emergency-reset hole in the User Guide for more information).
Use a straightened paper clip in the reset hole to reset the laptop. - On other laptops (without a pin hole reset or Novo button), press and hold the power button for at least 10 seconds.
- If the reset works, then there may be an issue with the power button. Contact support.
- After the power drain, reattach power cables, and power on the computer.
Note: If the power light is blinking, the laptop may be in sleep mode.
