How do I bypass my tablet's locks?

摘要

Q The touchscreen on my wife's Lenovo Tab3 7 Essential tablet has somehow been disabled, and now she can't log in and use it. Unfortunately, we don't have a manual, so I have no way of knowing if I'm doing the right thing. Is there any way I can access the settings to unlock the tablet? Baz Petterson DWe can't say for certain what's going on here but if literally nothing happens when you touch the screen, it could be a hardware fault. The first thing we'd try is a 'soft reset', which forces the tablet to restart and should resolve any software glitches. Hold down both the power and volume down buttons (on the right-hand side of the tablet) together for at least 10-20 seconds. If you get this right, the tablet will eventually reset to display a very basic-looking text menu.
