Lenovo ThinkPad W540 Series :: Displays Are Flickering Off And On Randomly

Feb 20, 2014

I just got me a W540 with docking. It is connected with two Samsung 24inc screens. They are connected with two display ports kables from the docking. I also have a wireless logitech mouse and keybord. And a Jabra headset connected.I have reinstalled it with windows 8.1 And now I have a serious issue that both screens turns off randomly while I work. They go black for 15 sec. And then re-appear. It seems like the computer looses all USB connection also while this happens. I sometime get an error msg. saying that I connected a USB device that cant be recognized. But most of the time nothing happens.

All 3 of us at work who has a W540 has this issue. So it must be known by Lenovo. I have an ongoing case with the support. But dosnt look like we are getting anywhere. They gave me this to try: URL...We think it could be a driver issue with the USB or that the computer is swiching between the Intel and the Nvidia gfx card.I think I have tried about everything, but can not figgure this one out. I have all the latest drivers from Lenovo installed. Tried to use a wired mouse and keyb. no change, tried with a DVI and Displayport to the screen. No change.
 
Here is a link to Lenovos System report on my W540. URL...

Lenovo ThinkPad W Series :: LUT On W530 For Calibrating Two Displays

Dec 13, 2013

I am looking to update my laptop used for photography. The ideal replacement looks to be the ThinkPad W530 with a dock and display screen. As the W530’s will be used away from home it and monitor will need to be calibrated.
 
I have been told I can only do this if the graphics card, NVIDIA Quadro K2000M, supports has more than one LUT to both laptop and stand alone monitors be calibrated.

Lenovo ThinkPad W Series :: W540 Won't Wake Up?

Sep 7, 2014

My new W540 has the latest bios & software updates.  It won't wake up from sleep...or rather the display won't come on.  When I push the power button (pulsing green), it goes to solid green and the fingerprint scanner light turns on, but no screen.  I scan my fingerprint and the scanner light turns off, but still no screen.  The only way to bring it back to life is a long press on the power button and a reboot.
 
Nothing plugged into any of the ports.  It does this regardless of whether it's plugged in or on battery.

Lenovo ThinkPad W Series :: New W540 Will Not Shut Down Or Reboot

Sep 7, 2008

I waited a long time for this new W540.  Downlkoad all the newest drivers and did all the updates and now this POS will not shut down.  Just goes to a black screen and have to hold the power button to force a shut down.

When I try to reboot the screen goes to black right after the home screen with a twirling cursor.  Had to send my new W530 back for hard drive failure and now this W540 is screwed, too!

Lenovo W540 ThinkPad W Series :: Won't Wake Up From Sleep

Oct 31, 2014

When I put my laptop to sleep or it sits idle for a period of time and goes to sleep on it's own it stops recognizing the laptop monitor.  It will still display on other monitors connected through the docking station, but not the laptop.  It doesn't matter if I put it to sleep while on the dock or off the dock, it never recognizes the monitor.  
 
I have an Intel HD Grpahics 4600, and an NVIDIA Quadro K1100M video cards.  I've checked drivers for both and they both say they are up to date (9/29/14 for Intel, and 09/12/2014 for NVIDIA).  I have also updated every possible thing in the Lenovo System Update.
 
This problem occured after switching from windows 7 to windows 8.1.I have also lost the ability to control the brightness of my laptop monitor through my computer at any point in time.  The function keys don't work, and the setting is not shown on my power manager.

Lenovo ThinkPad W Series :: W540 Is Running Even Though Lid Is Closed

Sep 9, 2014

I got my w540 in about 2 weeks ago, and finally had a chance to start migrating everything to it last week.  I bring my laptop(s) to and from work everyday and right now I'm bringing a w520 and my new w540.  But everyday since I started bringing my w540 home with me when I get home the laptop is running when I take it out of my bag. 
 
So yesterday and this morning, I made 100% sure the laptop was in sleep mode and nothing was running before I put the laptop in the bag.  I get to work 15 minutes later and the laptop bag is about 150 degrees because the w540 is running even through the lid is closed.

Lenovo ThinkPad W540 W Series :: BSOD During CD Boot?

There is no UEFI/BIOS options to set the 'SATA Controller Mode' accordingly, nor does the [F7] text mode option work.

Lenovo ThinkPad W Series :: W540 Dock Compatibility?

Oct 7, 2009

We have three dock posibilities:

- basic dock
 
- pro dock
 
- ultra dock
 
They differentiate by the number of ports and by the power adapter supplied with them. I had an opurtunity to try my W540 on pro dock, which normally has 65W or 90W power adapter. The computer warned me about insufficient power, and did not charge on dock, everything else worked fine. The I disconnected 90W and connected my original 170W power supply to the doc. Everything is working normally since.
 
So, my question is: Since I don't need all the ports on the ultra dock, nor on the pro dock. Would basic dock work with W540 and 170W power adapter too?

Lenovo ThinkPad W Series :: W540 Won't Charge While Running

Nov 18, 2014

My W540 recently became unable to charge while the laptop is running.  When the laptop is off, the battery will charge completely.  As soon as Windows (or Linux) boots, the charge terminates and the computer starts running off battery power.  The computer will boot without the battery installed, but the computer turns off as soon as either operating system is booted (a few seconds after the desktop appears).
 
I have tried a different power adapter without success (both adapters are Lenovo 170W supplies) and also put a different battery in (also genunie Lenovo battery) but the issue still remained.
 
The laptop is still under warranty, could it be the charging circuit on the motherboard?  Will I have to ship the laptop back to Lenovo for repair?  I am out at sea and might have to wait a while to get back into port to be able to ship the unit back to Lenovo, so I would like to investigate other options.

Lenovo X Series ThinkPad :: 2014 - X1 Carbon Flickering Screen

May 25, 2014

Just received my new X1 model#  20a70037-US last week and right out of the box the screen was already flickering. When the laptop is booting up in the POST screen you see a bunch of little white dots all over and as soon as you get to the windows login screen the flickering begins. Just like on this video I found online [URL] ....
 
I uninstalled the Intel drivers and now it's flickers less and the laptop is somewhat usable. I should be receiving my replacement unit this week, can't wait to have this laptop working 100%.

Lenovo ThinkPad W Series :: W540 - Multi Monitor Configuration

Sep 25, 2014

I have a W540 Laptop with 170W Ultra-Dock.  I have setup 3 external monitors, but can't seem to get my 3rd monitor to run at 1920x1080.  Whenever I set it to that resolution and I move a window to that monitor, the window flickers and shakes.  
 
I have my right monitor at 1920x1080 (VGA), my middle monitor at 1080x2560 (DisplayPort), and my left monitor at 1440x900 (HDMI) - this is the monitor that I can't get to work at 1920x1080.  
 
Wondering if there is a max number of pixels that the graphics card can handle?  I am using a NVIDIA Quadro K1100M 2GB graphics card.
 
I read on a review of that graphics card that it can support 4 monitors and up to 4K resolution (although not sure if it meant that all 4 monitors could be at 4K - I'm thinking not)
 
How to make this work?

Lenovo W540 ThinkPad W Series :: Won't Boot From USB Flash Drive

Mar 29, 2014

I just got a new Lenovo W540.  I installed a new Samsung EVO SSD inside to replace the stock mechanical hard drive.  I'm now trying to boot from a flash drive to clean install Windows.  I've done this so many times before on other laptops and desktops without a problem.  For some reason now it will not boot from the flash drive.  It shows it as available in the BIOS but it looks like it reads it for just a second and then goes right back to the screen that allows me to choose which drive I want to put to.The same flash drive works fine in other computers to boot to.I did check to make sure the USB drive was not excluded in the BIOS and it is not.

Lenovo ThinkPad W Series :: Numeric Keypad On W540 Not Working

Sep 6, 2014

I might have seen the numeric keypad keys work once since getting this machine, but now can't get the keys to produce numbers.  Some of the keys initiate other actions not associated with numeric data entry.  
 
I tried removing the wireless dongle for my Microsoft wireless mouse but no improvement  --  I simply swapped this MS mouse from my old W510 without doing any formal install.  
 
This doesn't appear to be a hardware problem since the keypad keys have some effect  --  just not the intended effect.

Lenovo ThinkPad W Series :: W540 - Microphone Mute Is Not Working

Sep 17, 2014

I have a new W540, and the microphone mute button does not work properly. When I press fn+f4. the red LED turns on, the slashed out microphone appears on the screen, and the volume settings for both the "Microphone" and "External Mic" are muted in Windows. However, audio from the microphones still capture audio, and it can be recorded on applications like Audacity and Skype.
 
Manually muting the microhphones via the Sound dialog in Windows has the same effect. The LED and OSD come on, but the microphone does not stop recording. As of now, I have found no way to mute the microphone outside of muting sound input in each individual applicaton.

Lenovo ThinkPad W Series :: W540 - Boot From Second Hard Drive?

Jan 29, 2014

I've recently got an ultrabay adapter and wanted to know if I could run two separate OSs, one from each hard disc.
 
Effectively, I would like to have one version of windows on the internal HDD for general day to day stuff and one as a programming environment and be able to select which to boot from at start up.
 
I know I could just use a VM, but some of this stuff (Siemens PCS7) can put quite a strain on the system and I'd rather not have that overhead.
