There could be multiple reasons why your device is not turning on. Consider checking to see if your charger is working properly by testing it on a separate device. If it is not a defective charger, then there may be more serious issues such as a faulty motherboard or display screen. For more information regarding a defective motherboard or screen damage, please refer to the Garmin Nuvi 2589LMT troubleshooting page [[Garmin Nuvi 2589LMT Troubleshooting|here]].
