1. Turn the laptop off.

2. Disconnect the charging apparatus.

Notes:
1. If an EC reset hole does not exist, or if the outlined procedure fails, then power off the laptop and press and hold the power button for 30 seconds.
2. If the battery is removable, then remove the battery and wait for 15 minutes before placing the battery pack back in its original position.
3. The location of the reset hole can be learned about in the manual. Manuals for all devices are available on MSI's official website.
4. To confirm that the EC reset is complete, press the power button and make sure that the system will not power on; if the system boots up after pressing the power button, return to step 3 and perform the EC reset again.
