I have problems turning on my Lenovo Tab M10

Connect the charger to the socket and to a wall socket.

When the battery charging icon is displayed, charging is in progress.

When your tablet is turned on, you can always see the battery power level. The larger the coloured section of the battery icon, the more remaining battery power.

Press and hold On/Off until your phone is turned on.

Key in your SIM PIN and press arrow right. The default SIM PIN is 0000.

If an incorrect SIM PIN is entered three times in a row, your SIM will be blocked. To unblock your SIM, you'll need to key in your PUK. O2’s help guide will tell you how to get your PUK. Please note: If you key in the wrong PUK ten times in a row, your SIM will be blocked permanently. In this case, you need a new SIM from O2.

Press and hold On/Off.

Press Power off.

Press OK.
