When the CMOS battery in a PlayStation 5 dies, you’ll still be able to use it to play games, according to a new report.
A new video from Hikikomori Media declares that a PS5 with an expired or missing CMOS battery will not stop the launch of any PS4 and PS5 games on the console. The CMOS battery powers a PlayStation’s internal clock, so when a game is started, the internal clock verifies the date and time on a remote server to make sure you can play that game.
Previously, when a CMOS battery died or was removed, the PlayStation console would ask that you manually plug in a date and time. It would then try to sync them online. If the PlayStation Network wasn’t working properly at that time, then the console won’t connect, making any games unplayable. This applies to all digital games, as well as PS4 physical games and a number of PS5 ones. However, this appears to no longer be an issue.
This means if there was ever a problem with the PlayStation Network being down (permanently or not) in the future, players could still access their games regardless if the CMOS battery was dead. Sony released an update to PS4’s back in September to correct this problem.
