My Lenovo tab 2 A10-70F is 2 years old. Yesterday, for the first time ever, it would not turn on - there was no vibration or anything to signify that the On button is working. I plugged it in overnight and today - when I press the On button, again there is nothing. I have been reading online forums and the best solution seems to be to take the back off the Lenovo, disconnect the battery and drain the system for about 30 seconds, by pressing the On button with the battery disconnected. Then reconnecting the battery, testing by turning on before replacing the back - and then replacing the back. I am looking for another possible solution that does not involve taking the back off the tablet. Is there any other solution other than returning the tablet to the factory? It is no longer under the one year warranty.
