Chrome OS Update v91 Backfires on Some Chromebooks


Users would agree that Chrome OS is one of the best performing operating systems out there. The minimal hardware requirement and blazing performance of the operating system have made it the favourite for many. In case if you’re feeling that your Chromebook is dragging, the developers at Google might be to blame. If it’s not, then it might be good for you to know that a recent Chrome OS update backfired on some Chromebooks. Various reports indicate that users are facing minor to significant performance drops in their Chromebooks after the update.

Many uses have taken the issue to Reddit. Also, the ongoing Chromium Bug Tracker would give you an idea of the extent of the problem. These users have reported that after updating their device to Chrome OS 91.0.4472.147, the CPU usage is maxing out even when idle. Users said that the issue came in right after their PC was updated. Lucky for us, there appears to be no solution for the bug, neither has Google acknowledged the bug.

A user has reported that the CPU usage hits all the way up to 100%. He also said that the clock speed was dropping as low as 0.80GHz(800Mhz) after the update, something we’ve missed since 2000. Lucky for you that you’ve got a chance to relive the 90s if you own a modern Chromebook. According to Android Police, most reports are from users who own Chromebooks using 10th Gen Intel chips. AMD models are least affected, but remember that they’re in the race to catch up with the blue team.

We highly recommend that you hold off the update until Google comes up with a solution. But as always, they must first acknowledge these performance issues. In case if you’re an early updater, there is something that you could try to restore your Chromebook to its former glory. You could patiently try switching to the beta channel, or if you’re a pro, we highly recommend that you downgrade your Chromebook to the previous stable version.


  1. Google has got to stop letting the “work experience kid” get near the upload the update button. Who do they think they are Microsoft?
