On Lenovo M625q thin clients, the error message "Chroot icachroot.service still not usable after timeout" may occur sporadically. This error can cause a significant delay when logging in via the SAW login screen.

To resolve this issue, updating the BIOS/UEFI to version M1WKT51A or newer is recommended.
Updating the BIOS/UEFI to a version newer than M1WKT27A should resolve the timeout error and improve the login speed for users on the Lenovo M625q.

Steps

   • Check the current BIOS/UEFI version on the Lenovo M625q device.
   • If the version is older than M1WKT51A, proceed with the update.

The error is caused by outdated BIOS/UEFI firmware that fails to initialize the icachroot.service within the expected timeframe, resulting in login delays.
