Earlier this year, reports were circulating that the PlayStation 4’s internal clock had to potential to essentially brick millions of consoles. Thankfully, those who are still using their PS4’s as their main system won’t have to worry, since the issue appears to have been fixed with firmware update 9.0.
The console’s internal clock is tied to playing games and unlocking trophies. When playing a game, the PS4 checks this clock to make sure it hasn’t been tampered with, before it can allow users to play. This is to prevent players from changing dates to make it look like trophies were unlocked earlier than they actually were.
However, if the CMOS battery powering the clock dies and the PS4 isn’t connected to the internet, the PS4 has no way to check the internal clock. This results in the console being unable to play games at all.
Thankfully, the issues appears to have been resolved. As its been reported on Twitter and verified by YouTuber Modern Vintage Gamer, who actually tested these reports. Modern Vintage Gamer removed the CMOS battery while running a PS4 on the new firmware and confirmed the issue was fixed.
Eventually, Sony will shut down PSN support for the PS4, like they almost did with the PlayStation Vita and PlayStation 3 digital stores–a decision Sony later took back. If this issue wasn’t fixed and the PSN support was shuttering, millions of consoles with dead batteries would just be unplayable.
