Won't Turn On
Kobo E-reader
Severity: CriticalWhat Does This Error Mean?
A Kobo that will not turn on usually has a drained battery. Charge for at least 30 minutes, then hold the power button for 15-20 seconds to force a restart. If nothing happens, try a different cable.

How to Fix It
-
Plug in and charge for at least 30 minutes.
A completely dead battery needs time to accumulate enough charge to boot.
-
Hold the power button for 15-20 seconds.
This forces a hard restart. Wait for the Kobo logo to appear.
-
Try a different USB cable.
Newer Kobos use USB-C. Older models use micro-USB. Make sure the cable supports both data and charging.
-
Try a factory reset if the Kobo boots to a blank screen.
Hold the power button and the light sensor (top center) together for 15 seconds. This triggers a factory reset — you will need to set up the device again.
