Indications the Chromebook may be in deep sleep mode:
- Chromebook has been unused for a long period of time (over a weekend, for example) - regardless of whether it was charging or not
- If it has been confirmed that it was charging or is still connected to power, the Chromebook still doesn't wake up/turn on.
- Power light on side is on or blinking, but pushing power button itself doesn't seem to do anything.
The Dell Chromebooks we use in district have a tendency to go into a very 'deep' sleep mode. When the Chromebook is in this mode, it behaves as if something is wrong and opening the lid or pressing the power button will not turn the device on.
When the Chromebook is plugged in, the light will blink indicating that it appears to be charging but will still not simply turn on.
Resolving this usually takes about a minute once you know the steps.
What to do to resolve this:
1. Make sure the Chromebook is actually completely off.
If the Chromebook is plugged in, unplug it. Then hold down the power button for about 15 seconds.
2. Plug the power cable back in. Hold down the "refresh" key while pressing the power button. You may want to be sure you've held down both for about 5 seconds and then releasing both keys.
The refresh key is just over the "4" key. It looks like an arrow bent into a circle.
3. The Chromebook should start up but it may take longer than normal that first time.
Booting from "deep sleep mode" may take longer than a normal start up. Once you see the "Chrome OS" logo, you know things are back to normal.
