We are starting to see some situations that you see a blank screen when you open a Chromebook (particularly on newer Chromebooks with the numeric keypad).
?
These are situations where "Recovery mode" is useful:
¡ñ Blank screen, chromebook unresponsive
¡ñ Chromebook comes to you at an OS version higher than 126, and an "update" doesn't automatically roll it back
¡ñ Cryptohome corrupted
?
To enter recovery mode:
Press and hold
Esc + Refresh

? , then press Power

.? Let go of Power.?
? ? ?
On some Chromebook models: Press and hold
Esc + Maximize ?

, then press Power

.? Let go of Power.
When a message shows on the screen, let go of the other keys.

If you see a message for a Recovery Device:??Press CTRL D
?
Please remember when you are finished with your Chromebook to select Shut Down?rather than just closing the lid.
