When a computer function works in another app, user account or port, keep the repair inside the failing context. For Chromebook account and settings sync, first verify the exact account and sync categories on another trusted browser.
What this covers
- Chromebook account and settings sync with this exact failure state
- Diagnosis across local profile versus Google Account sync, policy and network
What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleName the failing app, user account, port or peripheral and one that still works. Expected behavior: restore the intended bookmarks, apps and preferences for the signed-in profile.
Isolate the component boundary
ReversibleVerify the exact account and sync categories on another trusted browser. Swap only the app, account, cable, port or user profile while keeping the computer unchanged. Boundary to separate: local profile versus Google Account sync, policy and network.
Correct only the proven cause
ReversibleEnable the needed category or remove/re-add the profile only after local files are backed up. Repair the isolated app, user profile, driver binding or physical path.
Verify and stop safely
ReversibleRetest both contexts after sign-in and one cold restart. Do not remove the owner profile or Powerwash with unbacked-up Downloads.
