Possible causes:

(1) The ventilation ports are blocked.

(2) The fan is covered with dust.

(3) The usage environment is improper (such as using it on the bed).

(4) The fan is faulty.

Solutions:

(1) Ensure that there are no obstructions at the bottom and side ventilation ports.

(2) Use a cooling stand.

(3) Clean the fan regularly (it is recommended to have professional cleaning once a year).

(4) Avoid running large software/games under high load for a long time.

(5) Check if there is a sound of fan rotation at the bottom shell outlet position. If not, it indicates that the fan is faulty and causing the laptop to overheat.

If the fan fails, please contact the after-sales team through the After-sales E-mail to follow the next after-sales policy.
