Troubleshooting

Symptom-first fixes for a Chromebook that won’t behave. Start with the problem you can see: a Chromebook that won’t turn on, a black screen, a device that is frozen or unresponsive or one stuck on the Chrome logo. Each guide lists the likely causes, then the fixes in the order worth trying, from a hard reset to recovery mode. Brand-specific versions for Acer, ASUS, Dell, HP, Lenovo and Samsung are linked from every main guide.
