W540 - Blank screen after undocking/sleep

2014-10-23, 19:49 PM

Hello folks.... I have a Lenovo W540 which has a simple problem that is frustrating me to no end. Whenever I undock the laptop, or bring it out sleep, the screen remains blank.

 

I end having to put it back in the dock (or RDP to it), which allows me to view the screen content on the external monitors.

 

I have updated all the drivers using the Lenovo driver app, and even applied the docking driver update. Nothing seems to help. I've searched the forums, but all that I have found is a suggestion to downgrade the video driver, which I dont really want to do.

 

Anybody else have this issue? Any ideas?

 

Thank you!!

 

//EDIT to add that this is Windows 8.1. Important information ;)

 

 

Solved! See the solution

Exact same problem here.

 

It looks like the only way to brink the device's lcd back is to boot the machine. Then it will work until the next time it falls a sleep while docked.

I'm running Windows 8.1 with latests drivers.

i have the same issue. 

and another more anyoing issue. when i turn my computer off (real shutdown, not hibernate or standby/sleep) and try to turn it on after a few hours the displays stays black. but the system is botting in background. when i attach an external monitor i can see the system is started normally. the only way to get the lcd back to life is unplugging the running machine and release the battery. so it'll turn off really hard. plugging the charger again and use the power button will bring the display back.

 

it is really annoying. i have the machine since 5 days and have this problem every morning!!!!!!!

please help asap, otherwise i will buy another fabricate and return the lenovo.

I started having this problem just this week after updating my drivers and the dock firmware to try and fix issues I was having with external monitors, and things actually seem worse than before.  Maybe there is a problem with some of the latest updates...

Unfortunately, no resolution as of yet. Some people are reporting similar (but not necessarily the same) issues and attempting to resolve by installing older sets of video drivers.

 

Before I venture into downgrading drivers, which I am less than excited about doing, I'd love to know if that has actually fixed the issue for anyone.

 

This is getting really annoying, and although multiple people are reporting the same issue, I cant find any confirmation of the issue from IBM. As soon as I figure out the solution, I will be sure to post it.

Exact same problems.  I wonder where did you guys purchase the machine? I have a Window 7 Pro and it happened after a couple system updates.  I wonder it has something to do with the display setting/power setting. The first time they repaired my hard drive.  It fixed the problem for only two weeks. I will ship in to get it repaired(second times!!!) Will update once I get back from Levono.

I purchased mine in Sweden (Dustin.se). 

When the W540 goes into sleep and wake up, it only detects the external monitor (the rgb output), the internal LCD screen is lost (not visible in the Device manager).

Only way is to reboot to get it back.

I have the exact same issue. Laptop goes to sleep, when it resumes I can only use the external monitor and the native one is not present in Device Manager. Scanning for hardware changes does not bring it back. Confirmed I am on the latest BIOS and drivers. This is a VERY annoying issue and I am hopeful that a fix comes soon.

I have this problem, but only when rebooting. Sleep works without issues, but when turning on the computer with an external monitor connected, only the external is usable until rebooting.

I have this same issue. They told me to return it under waranty and they would swap out the motherboard. I have a feeling this is a software issue, not a hardware issue, but I will give it a try anyways.  I have tried everything including older drivers and nothing has worked.
