1. Check the Lid

The lid is closed, but the electronic lock cannot retract properly, preventing the lid from opening.

(1) Press the left side of the lid until the electronic lock retracts.

(2) If you find warping or deformation that hinders the safety lock from resetting, push down on the side to ensure that the lid is completely closed, and then restart the device.

(3) Attempt to restore the lid once the safety lock has been unlocked.

(4) You can refer to the following video for adjustment. However, make sure to place a soft material underneath to avoid scratching the enclosure:

2. Check for foreign objects

(1) Remove the left upper cover.

(2) Check for any foreign objects and remove them.

3. Check the safety lock

(1) Refer to the tutorial in the note for guidance. Check if you can control the safety lock as intended.

(2) If not, check the mainboard cable:

• Remove the left upper cover.

• Inspect the cables on the main control board for any signs of breakage, or unplug and reconnect the cables to make sure of a secure connection.
