Lenovo Z51-70 sometimes black screen after sleep

I have a Lenovo Z51-70.  Sometimes the screen stays black when you lift the lid up.

 

I know that a lot of other people have had this problem.  HDMI out shows the machine has booted.  Rebooting the machine clears the problem until the next time.  Windows 10, fully patched.  I have the latest Bios, and both of the latest graphics drivers.

 

Can someone point me at a systematic guide, of the 'first try this, then try this' type?

 

Regards, Stephen

Re: Lenovo Z51-70 sometimes black screen after sleep

Hello StephenB-2000

Thanks for using the Lenovo forums.


Try to download the Chipset drivers for the unit from the support page.

 

Make sure to reboot after an update on the unit.


Also, Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

See if this is able to help at all, let us know how you get on.

Updating the chipset drivers did not help.  But thanks for the suggestion.  Somewhere, someone must  have developed a systematic approach to this problem.

Time to mark this issue as 'not solvable' and put it down to experience.  Lesson: never buy Lenovo.
