Lenovo a7-30 won't turn on, stuck at black screen

Hello.

Yesterday I have bought this Lenovo tablet 2 a7-30.

when I try to turn it on, it shows the Lenovo logo and then it shows black screen for about 5 minutes and then it shuts down.

I can access the recovery and I tried to factory reset it however that didn't help.

Also when the tablet is charging, it shows the battery icon but the whole screen is glitching and is showing random colors and lines.

any idea how can I fix it?

thank you

If you can turn your tablet on but it won’t get past the logo screen, then this is usually easier to fix than if it won’t turn on at all. This typically means that there’s a problem with the software on your tablet, which is an easier fix in general. Here’s what you should do if this happens.

Restart your tablet

The first thing that we always want to try with any tablet is to simply restart it, or perform a factory reset.

To do this on a Lenovo tablet, you’ll first want to hold down the power button. Whilst you’re doing this, also hold down the volume up button at the same time. This should bring up the system recovery screen. Here, you’ll be able to choose to factory reset your tablet.

Start it up in safe mode

Another thing that you can do to try and get your Lenovo tablet started again is by trying to start it up in safe mode. This is just a special mode that devices like tablets and computers have that can be used as a diagnostic point to identify fix any of the problems with its operating system.

You can launch safe mode in a Lenovo tablet by;

The first thing that you’re going to want to do is make sure that your phone is turned off beforehand, and it isn’t stuck on a screen but still on.

Then, hold down the power button to turn the phone back on again, and the Lenovo logo appears on the display.

Very quickly hold down the volume down button, which should activate safe mode on your tablet.

If you want to turn safe mode off, then you should just repeat this process.

Greeting,
