After you have tried what @shiham said if that dosen’t work then open the device. unplug the battery and then plug it in. if the device doesn’t power up then while plugged in still do the wash sequence Esc, Refresh, and Power. If it does not come up after that the board is bad. If it does then proceed with the wash. After the machine comes up plug in the battery and test by closing the device and opening it again.

Plug in your chromebook.

Hold down the Esc, Refresh, and Power buttons until the charge light turns to solid red.

Leave it charging for at least 4 hours. Charge light will turn green.

Now it can be turned on.

try the step in the link

Hi, have a acer C771. both orange and blue lights flashings. Checked power supply and its ok. Tried another and same results. Removed battery and checked voltage with multi meter and completely drained. Connected power supply without installing battering and same lights are flashing and will not turn on. Performed the "wash" and is now asking for recover usb or sd card.

Is there not a reset button? Will this turn on without a battery? I don't see a cmos battery in the unit. Where to I get the recovery if needed?

thank you

On the Acer chrome book the charge light and power light are both steady blue but nothing on the screen. What’s wrong?
