(PC/ Laptop) Laptop-screen suddently very dark.


Recommended Posts

First of, pardon any spelling mistakes that i might make.

I have a really odd problem with my Laptop, Lenovo Z500, which i simply can't fix on my own. After a few minutes of normal pc usage on my external monitor yesterday i realized that my laptop-screen had suddently become very, very dark. My first thought was that i might have accidently changed the brightness whilst playing or something, but the brightness would not change at all.

(Now, before you come up with silly things like these; Yes, i have tried to switch it off and back on. Yes, i have tried to fix it using the energy-settings. And yes, i have tried to roll back/ reinstall both my nVidia and Intel HD driver.)

The problem did not vanish, and my laptop screen is so dark that i can barly see anything. The external-screen still works fine, and the problem did not occure when i started the laptop but a few minutes after . Thus i might take the guess that this is a software/ settings problem, but i simply can't find any serious solution to this problem anywhere. I really hope that some of upcomming patches for Windows or some new GPU-drivers might fix this soon, but i do not want to send my beloved laptop to a expensive repair. Please, help me!

My System: Intel Core i5 - 3230m (2C / 4T @ 2.6 - 3.0 Ghz) 8 Gb of DDR3 Ram GPU 1: nVidia GT 740m GPU 2: Intel HD 4000 HDD: 1 Tb SSHD OS: Windows 10, 64-bit all up to date.

Sounds to me like a hardware problem... If the external screen works, but your 'internal' one doesn't, how could it be the software causing trouble?

 

If you still have warranty, I'd suggest RMAing your laptop.

Hmmm, i've read that a couple of places now. But why should anything of my Hardware just stop working during normal usage? The Laptop was just standing there as always and i did nothing special, and i've never dropped it or something like that. It worked well for the first couple of minutes and then when it suddently became very, very dark after i had playd Skyrim for like 5 minutes (trying out a lot of key-combinations on my keyboard becaus of an ENB...) .

Now, i've had this problem about 1 and a half year ago, but back then i was still using Win 8 and i managed to fix it somehow...

Hardware can just be faulty. Not all video cards (of the same model) are the same. Some can be overclocked way further than others, for example. There's always the chance your video card came with a faulty component, and that the results of that are only showing now.

 

And you know, if you do still have warranty, you'll probably get a brand new laptop... Which is always nice, eh.
