Such as mobile phones, audio, etc., do not be placed next to the display, so as to avoid magnetic interference.
Step 9 The computer needs to carry out dust removal maintenance for half a year.
It is best to do a dust removal every few months. If you don’t know what to do, you can ask a professional maintenance person how to remove dust from the chassis to avoid damage to hardware or electric shock.
Step 10 The computer cannot be used overnight.
