Turn off the power supply and press the discharge button, which is also a temporary solution. But the most fundamental solution is to remove the dust from the keyboard by removing the panel, and cover the PS4 with a dust cover when not playing. It would be better if we could get into the habit of cleaning up soot regularly.
The ps4 game CD is the main running carrier of the game machine, and the host adopts the self-priming CD-ROM drive. Put the CD into the CD-ROM drive port, push it gently, and the CD will be automatically sucked into the CD-ROM drive.
After the recognition is successful, you can start the game. Press the ps key in the handle to choose to exit the CD or press the exit key of the host, the CD will automatically exit, and the CD needs to be wiped regularly.
