How long will it take for kobo arc to turn on if its been dead for months I plugged it into the charger but it sill will not turn on?

If your Kobo Arc has been dead for months, it may take some time to recharge fully. Typically, it could take at least 15-30 minutes of charging before you see any signs of life. If it still doesn’t turn on after a few hours of charging, the battery may be deeply discharged or damaged, and you might need to try a different charger or cable. If issues persist, consider contacting Kobo support for further assistance.
