Lenovo Z50-70 Screen flickering white horizontal lines.

Please help me.. I'm getting a bit annoyed by my Laptop screen. got a Lenovo Z50. It suddenly happened once when I started my laptop up and now it just keeps on doing it and never stops. I never hit it or dropped it, and never opened it either. I really hope someone could help me.

Re: Lenovo Z50-70 Screen flickering white horizontal lines.

Hello _BrenT_

Thanks for using the Lenovo forums.

Seems like this will potentially be an issue with the connection cables by the looks of it.


I would recommend that you attempt a factory reset, if the issue should persists after this, then it would confirm a hardware issue with the unit.


Note: Please back up all your data as running this reset will delete any data on your machine

1. Turn the machine off and press the recovery button which is located usually next to the power button. If you have a desktop machine you will need to power the machine back on and keep tapping the F2 key.
2. Use the arrow keys and press enter on system recovery. ( Desktop users can skip this)
3. Select “restore from the initial backup” and then “Next”.
4. Click “start” and accept the warning messages.
Length of time can vary depending on the speed of the machine.

 If these steps do not work I would recommend, that you call your local Lenovo support line for a possible service. Below is the link to the phone list where you can find these numbers


Hope this helps, let us know how you get on.
