When your notebook encounters keyboard, touchpad, or power management-related issues, resetting the EC may help resolve the problem.

Please refer to the following steps to reset the EC:

1. Turn off the computer.

2. Remove the power source.

3. Press and hold the power button for 30 seconds to reset.

4. Reconnect the power source and start the computer normally.

Note:

1. If the battery is removable, you can also reset the computer by removing the battery for 15 minutes before reinserting it.

2. After resetting, the notebook computer cannot be turned on by pressing the power button; this is normal and it means that the EC was reset successfully. The power adapter must be connected to start the battery when powering on for the first time after resetting, otherwise the battery cannot be used to power on the notebook computer.
