The Sony PS4 game console was launched in 2013, and it has been nearly 8 years. Several users reported that offline games cannot be played after the CMOS button battery on the motherboard of this game console fails.
Twitter user conducted a test and manually removed the battery and reassembled the game console. The game could not be loaded, and an error message with the modern number “CE-30391-6” was issued.
After removing the CMOS battery of the Sony PS4, neither the digital version nor the Blu-ray version of the game can be played offline, prompting the user to connect to the PSN network.
If you want proof of the #cmos issue with ps4's then heres video. I took out the battery and put the ps4 back together. The result, no physical or digital games work offline without connecting to Sony's server. ALSO may cause game install data corruption @dark1x @Dachsjaeger pt1 pic.twitter.com/ltCmh6M6rH

After successfully connecting to the Internet, the game can be opened and run normally. The service life of CMOS batteries can be as long as 3-5 years or more. The battery is used to power the timing chip on the mainboard.
Currently, the Sony PS4 series of game consoles have been on sale for many years, and the first batch of users will face a large number of CMOS battery failure problems, and users need to replace them by themselves.
