Lenovo W530 DISPLAY Doesnt work, EXTERNAL DOES- but: duplicate doesnt

Hello,

 

I own a Lenovo W530 (Machine Type 2438).

After installing Windows 10 the Lenovo Solution Center recommended a battery update, which I did, but didnt work. Since that I had some problems with my BIOS, but they stopped (re-enter date) .

 

About two weeks ago, my battery was empty and my laptop crashed.
When restarting it my display didn`t work any more. I thought that my display / display cable broke (i had reordered a display a week before due to stripes on my lcd caused by dumb cleaning).

After the new display didnt work I noticed that one cable of the intern display connection broke:

so I ordered a new intern display connection Smiley Very Happy

 

After installing it, it didnt work too and I observed, that I can connect and work via an external monitor problemless, but when trying to "duplicate" the laptop screen to the monitor it stays black, as the display does...

 

What do you recommend? Smiley Happy

 

Best regards!

Welcome to the forum!

 

Did you remove the main battery before you replaced the panel and the LCD cable?

 

Try booting with the internal LCD only, then after booting get a flashlight, point it to the screen and check if you can see a picture.

Thank you

I didn't get a picture :/

First I also thought about a broken BIOS battery, but since BIOS works without any problems I don't know what could be wrong?

 

An external monitor is working, so I think my GPU is working too - additionally both are recognized by the device manager.

 

Why don't I get a picture on my external monitor when selecting "duplicate desktop"?

I think, that my Intel Graphics is broken..

Now I would like to change my main GPU from the Intel to the NVIDA. How can I enter BIOS with an external monitor?

I was talking about the main battery, not the BIOS battery. If you swapped the screen without removing it, the backlight fuse on the motherboard can burn, which would as result produce a black screen.

 

This is provided that the new screen and cable work properly (and that you followed the instructions for replacement correctly Smiley Wink)

 

Edit: to boot into BIOS with the external monitor is the same procedure. Press F1 immediately after powering on your notebook.

Smiley Happy I hope i did Smiley Very Happy

 

 

the screen doesnt work since my battery pack was empty once..
so it shouldnt have anything to do with the swap of the display.

(when flashing with the flashlight at it i didnt get any image)

 

why cant i get an image on my external monitor when choosing "duplicate" but when choosing "2 monitor only"?

 

also with a GPU finder I only get the RAM of the NVidia but not of the integrated Intel?

I guess it's just showing the same result as the internal LCD, since this is one is black the replicaton will also result in a black screen

The Intel graphics uses part of the normal RAM, while the Nvidia has dedicated RAM for itself.

Have you tried the key combination Fn+F7?

are you sure that it is just a replication?

wouldn't that function use much more of the GPUs Capacity than just visualizing the data which the system "wants" to show on the main screen?

 

 

..

The combination FN+F7 wont work too Smiley Sad

 

PS: I added a picture of the "GPU finder"

Could the reason be a reed switch fault, due the color calibrator isnt finding an screen?

 

Or could the display's fuse has blown?
