My laptop display screen has suddenly gone black- how can I fix this? Thinkpad E470

Hey everyone. I have a Lenovo Thinkpad E470 and the screen suddenly went black. The computer is still viable because when I connect to an external monitor it works. However, I cannot get the display to work. I have noticed that the screen has had strange behavior in the past- it would briefly go black when plugging in a power source on occasion (albeit rarely), and if the battery was low, the screen would go black and even if I plugged it in, the screen sometimes remained unresponsive until I reset the computer. But restarting the computer always nullified the issue. I always figured maybe it was a loose connection or something but the black screen seems to be something others have encountered as well, so I'm not sure what the problem is. Today, I was in the midst of using the laptop when the screen suddenly went black (I don't recall it ever going black in the middle of use while plugged in). I have been unable to return functionality.

 

I have noticed that other people seem to have had similar problems with this model, so I am wondering if there has been any solution that's been discovered. Unfortunately, this model does not have a pop-out removeable battery, so I can't remove the battery and drain the energy for a reset, but I did let the battery run down as much as possible (the green light would come on for half a second but other than that, the power was dead). This unfortuately did not solve the issue.

 

If there is any insight that can be shared, I'd greatly appreciate it.

I had the same problem, but i fixed it bu downloading the CRU (Custom Resolution Utilty). When it's done downloading open the folder or rar/zip file and there will be 4 files:

1 CRU, for creating the custom resolutions

2 reset-all, use this only when you want to start with the base resolutions

3 restart, this is for any 32-bit system, this will restart al graphics drivers, ps when you use this and the screen stays black press f8 for recovery mode

4 restart64, this is for any 64-bit system, this will restart al graphics drivers, ps when you use this and the screen stays black press f8 for recovery mode

 

Solution:

First off, if you haven't, read the text above this one. If you're done proceed.

Double click the restart.exe file, if you have a 32bit system use "restart", if you have a 64bit system use "restart64". This wil restart all graphics drivers, this should fix your problem.

 

I hope this fixes your problem! Good luck.

And we're back...
