Your Chromebook may sometimes pop up a screen that says, “Your system is applying a critical update. Please do not turn it off.” Unfortunately, Chrome OS never seems to finish applying the update. It often gets stuck in an endless update loop.
Even if you wait for two or three hours and then restart the device, you won’t get rid of the “Applying a critical update” screen. Some users said that Chrome OS might sometimes take days to finish installing the update. If you can’t wait that long, let’s see what else you can do to fix this problem.

Fix: Chromebook Is Applying a Critical Update
Unplug All Peripherals and Force Restart the Device
Make sure to disconnect all the external devices connected to your Chromebook. Unplug your headphones, mouse, external hard drive, and so on. Then press and hold the Power button until your device shuts down. Wait for one minute, power up your Chromebook and check if the issue is gone.
You can also unplug your router and leave it unplugged while your Chromebook is booting up. Check if you notice any improvements when restarting your Chromebook in offline mode.
Reset Chromebook Hardware
If your device is still applying critical updates, press the Power button until it shuts down. Then wait for one minute. Press and hold the Refresh and Power buttons. Release the Refresh key when your device starts up. Check if your laptop boots up correctly.
Reinstall Chrome OS
Other users managed to solve this problem by reinstalling Chrome OS.
- Press and hold the Esc, Refresh, and Power buttons on your keyboard to enter Recovery Mode.

- Follow the on-screen instructions to reinstall the OS.
- Remove the recovery drive when prompted. Your Chromebook should restart automatically.

I have tried all of the above and it still just keeps coming up crucial update then shuts down and then repeats its message in infinite bucle.
If these steps do not work try replacing the Daughter Board in the unit. This seemed to solve this issue for me when all else failed.
I saw the message on update saying “Your system is applying critical update”
Ive everything! And it still wouldn’t turn on. I don’t have a usb. But i literally did everything it said and it still turned on to the ‘critical update’ screen.
I have tried the above and made a recovery os usb drive however the screen goes on to installing a critical update screen and then the screen goes black turns off then comes back on and continues this cycle all the time, as the screen is doing this the power seems to be turning off and coming back on as well?
Any ideas
We tried all of the above, Any more ideas?
I resorted to pressing Esc/Refresh/Power. I didn’t have a USB drive with Chrome OS on it so I chose the option to Power Off. The laptop started after that, so problem solved so far. I still need to check if this happens again if it tries to apply that same critical update. Maybe there was a bug which has now been fixed by Google?
Thank you.
I have tried all of the above and it still just keeps coming up crucial update then shuts down and then repeats its message. Also disconnected the battery.
