“Your Chromebook is locked due to a known issue” error message

Known issue

Some users can’t sign in to their Chromebook. The error message on the screen includes a countdown timer showing the length of time that users need to wait before they can sign in. During this time, users need to keep their Chromebooks powered on and connected to power. Users should not turn off their Chromebooks.


Option 1—Reset Chromebook to factory settings immediately

If users can’t wait the specified amount of time, they can reset their device to factory settings. Resetting erases all the information on the device’s hard drive, including all the files in the Downloads folder. For information about how to factory reset a Chromebook, go to Reset your Chromebook to factory settings.

After you factory reset the device, make sure that the Chromebook's OS has been updated to the latest version. For details, see Update your Chromebook's operating system.

Option 2—Save files by first keeping Chromebook awake for 48 hours

Some users might have files that they need in their Downloads folder that are not backed up to Google Drive or an external storage device.

On Chromebooks that are showing the error message:

  1. Make sure that charger or adapter cables are fully plugged in to the Chromebook and the power outlet.
  2. Sign in as a guest.
  3. Update the Chromebook’s settings so that it stays awake:
    1. At the bottom right, select the time.

"A registration certificate could not be obtained" error message

Known issue

You will see this error message when forced re-enrollment is enabled on a Chrome device. This error occurs when auto re-enrollment fails because the device is connected to a network with TLS or SSL inspection that does not have the hostname "" allowlisted.


Users can switch to the manual re-enrollment screen by clicking X in the top-right corner of the error screen. Or, the administrator can allowlist the hostname on the proxy server to allow Chrome devices to automatically re-enroll.

Some Chromebook batteries don't recharge after prolonged storage

Known issue

Lithium ion batteries typically drain slowly when left uncharged for long periods of time, such as during school breaks. The Chromebook models below may discharge so deeply during storage that it affects the battery’s ability to be recharged:  

  • CTL J2 / J4 Chrome for education device
  • CDI eduGear Chromebook K Series
  • HiSense Chromebook 11
  • Poin2 Chromebook 11


For instructions on how to store these devices for a long period of time, see Storing Chromebooks long term.

Limitation on number of saved hidden SSID networks a Chrome device can scan and connect to

Known issue

The number of manually saved and managed hidden SSID networks that a Chrome device can scan and connect to is limited by what the WLAN chipset supports, which can vary between Chrome device models.

This can be verified on a Chrome device in dev mode with the following command:

$ /usr/sbin/iw phy | grep -i ssid

As an example, entering this command on an Acer Chromebook C720 would result in the following:

$ /usr/sbin/iw phy | grep -i ssid
        max # scan SSIDs: 4

In this example with an C720 gives us the answer 4. One is consumed by the scan, so it is advised to have a maximum of three hidden SSID networks saved on the device, either by managed network policy or manually added.


We encourage customers not to use hidden SSID on their access points.

Important: Please tag these cases with - "FR: Support for more hidden SSIDs than the hardware supports".

Users need to enter CAPTCHA challenge for Search

Known issue

This issue can occur if your organization routes all search requests through a single IP using a proxy. Google Search might detect these requests as potential spam and abuse, which triggers a CAPTCHA challenge.


  • If you use the DefaultSearchProviderSuggestURL policy, change the URL to {google:baseURL}complete/search?output=chrome&q={searchTerms}.
  • Run a malware check on your network.
  • Stop users from using Hola VPN.

Device management

Can't re-enable a disabled Chrome device

Known issue

If you have tried to enable a device running Chrome OS, but the device stays stuck in disabled mode, check the serial number.

To find and check the serial number:

  1. Turn on the device.

  2. Before signing in, press Alt+V.

  3. Compare the serial number you see on the screen to the serial number printed on the device. Some refurbished or otherwise modified Chrome devices might have incorrect serial number stickers.

  4. If the serial numbers don’t match, the printed number is incorrect. If you use the printed number in the enable command, the command will fail.


We recommend that you ask the manufacturer to replace the device. If you continue to use the device, use the serial number found on the screen (not on the device’s sticker) to manage the device.

For more details, see View Chrome OS device information.
