Q: L540, ext. 4K Display high CPU

Hey @all,i'm new in the forum, but i am using Thinkpads for years. I run my L540 (i5-4300M CPU, 4GB RAM, 128GB SSD) in a Pro Dock (40A1) with an external 4K Display.The Video Performance is very bad with that 4K Display, not only Video, minimazing and maximazing Windows isn't smooth...it really jearks.So my question: does Upgrading my CPU to a i7 CPU improve the video performance?Second question: must i use a 37W TDP CPU (4702MQ or 4712MQ) or does it also work with a 47W TDP CPU (4710MQ)?Thanks for your help!!!Many Greetings,Baschi

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I only started daily use of my L540 with Windows 7 Professional recently and am encountering a black screen sometimes when the Thinkpad has been powered on for a while and not in active use.  When I press any key, which is what I am used to doing to return the computer from sleep mode, nothing happens.  When I press the power button, sometimes the Thinkpad powers off instead.  (By the way, when I see the screen saver,  I am able to hit any key and return to an active screen.)  Please advise if I have a malfunctioning computer or if I am doing something wrong or have the wrong power settings.

Hi, I've installed over 50 HP Z210 workstations at my office.  However, I have one with known bad video (it had a six-beep startup audio code), and two that I cannot diagnose. I launch the stations, the Light on the front lights up and I can hear the fan.  No signal reaches the monitor (I've tried different monitors and replaced cables, and tried both the VGA and the graphics port connections).  After about 30 seconds of waiting for something to come up on screen and the monitor timing out and going to sleep, the fan on both computers kicks into high and you can feel a strong gust from the back and hear it running at full speed. Unlike the one known bad unit (which I haven't had replaced yet), there are not beep codes for these two, and because the display never shows anything more than the fact that it's querying to see if there's an Analog or Digital connection before it goes back to sleep, nothing comes up on screen. Thanks for any suggestions.

A:Z210 - No Display, Fan goes on "high"

Did you add a graphics card or using onboard graphics? If you're using add-on video card, please replace it with the one in one of working systems. If you're using onboard video, please reseat the processor. If this does not work, please replace the processor with the one in one of working systems.

Hi,

I'd really appreciate some help on this one - it doesn't seem to affect the function of the computer it's just annoying !

Since I picked up the 'new' tower the display on my monitor is too high - and by that I don't mean the resolution - the taskbar has a black gap about 1/8" (3mm) below it and the rest of the display is therefore 1/8" further up ! This means the tops of any icons at the top of the screen are cut off and I can't see the floating Ashampoo Snap 5 toolbar which sits at the top of the screen.

As I say, this doesn't affect function it's just damn irritating, I can still use the top icons and when I put my cursor up to the top of the screen the Snap 5 toolbar drops down.
This is probably a simple fix if you know how but I don't - if anyone out there does please let me know !

Many thanks,
ams

Hi all, I need to rent a 20-23" LCD, 1600x1200 standard (and also a widescreen LCD 1900x1200 same size too) for an exhibition in October in Seattle.

Does anyone where I can rent these sort of high quality LCD screens??? I've tried all the places I can find on the web but to no avail. They've got to be high res as we're showing a top end graphics app.
The Widescreen ones I've been looking at are the Sony SDM P232W-B and the HP L2335
There seem to be plenty of 1600x1200's around to buy - but to rent......... is another story.

Very grateful for ANY help on this......

I just switched to a high contrast display to make reading screen easier pressing together the left shift left alt and prtsc keys. One of the forum threads says this sequence is a kind of toggle so that doing it again turns off high contrast. Didn't for me. Instead, it produced a menu asking if I wanted to turn on high contrast with yes and no options. I tried both and in each case the menu closed with no change.
In short, how do I get out of the high contrast which I find almost impossible to read (I'm 74 and have less than the best eyesight)?

A:get out of high contrast mode for display

I am trying to lengthen battery life by using a black back ground. I can create the look I want using a High contrast theme. The strange thing is some web pictures do not display. I have Yahoo as my home page. Most pictures display but not all do. If I flip the theme to a non-high contrast one all pictures appear. If I position my cursor over where the pic should be the browser recognizes the pic's link and when clicked on I navigate to link. At the link the pictures do display there. I have not tested any other sites to see if problem exists there.

Any solutions out there?

Thanks,

A:High Contrast Display not displaying all web pictures

Hello,

I'm not sure how well the high contrast can save battery but it worth a try.

What browser do you use?
If the browser switches to high contrast then colors and backgrounds of websites also change. This is the case for IE and Firefox. Chrome seems to ask for HC extras but if you ignore them, you can still enjoy the sites in their original color even if you're on high contrast for the rest. Disabling HC in other browsers still needs to be investigated, if possible or not.

On yahoo site it seems that the icons are invisible on high contrast, pretty weird. Chrome can display it fine if you run it without the extra extentions for high contrast, I believe Oper can do that too.

Another drawback of high contrast, mentioned on my special themes thread, is that it seems less graphic-accelerated: frames of some 3D programs aren't shown only on forced refresh, whether that is possible, like in your case: only on click/navigation the pictures are shown.
I didn't see the issue in yahoo yet as I'm running it in Chrome, to avoid the color changes, but desktop programs like: Stellarium, Cinema 4D and After Effects suffer from empty screens on high contrast. Only if you render content you'll see something and in case of Stellarium only a task kill can save it.

IMO, OpenGL doesn't run as it should on high contrast of W8.
EDIT: WebGL in browsers runs fine, mobile apps run.

I hope MS knows about the issue and if it's an important one or not we'll have to see if Windows 10 will fix it.... Read more

Hi,
I've just taken delivery of a 9550 with the 4k display. This is my first experience of a high DPI display in windows. When I'm in work, I extend my windows desktop onto a 24" HD monitor. So I have the laptop set to 225% scaling, and the 24" monitor set to 100% scaling. The issue is that when I first connect the external monitor, although the fonts are the expected size, they look fuzzy. If I designate the external monitor as the primary display & reboot, images then become sharp on the external monitor, but fuzzy on the laptop (although they remain scaled correctly). 
Similarly, if I then disconnect the external monitor, text remains fuzzy on the laptop until I reboot.
Essentially, although I can set scaling individually for each monitor, I can only have sharp text on 1 monitor at a time, and need to reboot following disconnecting/reconnecting the external monitor in order to get sharp text on the primary monitor.
Is this a windows thing, an intel driver thing, or a dell thing? Or none of the above?! Is there a solution?

Hi @FizzyLicious, Welcome to the HP Support Forums. From your post, I gather that your Compaq no longer boots up but the fans are starting and some of the lights used to blink but don't seem to be anymore on startup. Please follow the troubleshooting steps in the HP and Compaq Desktop PCs - Resolving Startup Problems (Windows XP, Me, and 98) document. It will walk you through the troubleshooting. I suspect that you are going to end up having to follow the steps in the HP Desktop PCs - Computer Does Not Start and Emits an LED or Beep Code document. If this post helps you to resolve the issue, please pay it forward by clicking "Accept as Solution", to the right of the Thumbs up icon.

A:Qosmio F755-3d150 - Win 7 - no High definition on external display

In your other thread I read that you have problems installing some drivers.
I guess the issue is related to missing graphic card driver and therefore you are not able to choose higher display resolution for the external display.

But if you have already installed the right graphic card driver, then I would recommend you to check the external display resolution settings.

Hi Guys,

I have have this horror issue with my PC. I have even changed the hardware configuration and the problem still persists. My PC fails to display the desktop correctly after using highly RAM intensive applications, especially Chrome, but even after getting the chance to close it, or waiting for it to crash by itself, the PC is still not able to display correctly the GUI, even on other browser/applications as shown in the screenshots.



1st Hardware Config:
Intel Core2Quad Q9450
4x2GB DDR2
MSI P43 motherboard
Ati Radeon x550 video card

Software used, that seemed important for me to mention:
NOD32 v4.2
Comodo Firewall 5.12
Chrome
Screenshot Captor
SpeedFan


Other mentions:
Aero is disabled, because I've considered that it's one of the causes.


So, I've considered that it's a RAM issue or a videocard issue, and I've upgraded to:
Intel Core i7 3770k
4x8GB DDR3
Asus P8Z77V-LX motherboard
Intel GPU integrated in the 3770k CPU


The problem just happened 2 times on this rig also, and the RAM was not even coming close to it's maximum capacity of 31.7GB. It was at ~20GB's.
Also, this is another videocard(Intel's integrated GPU), so we can exclude the videocard from the suspects.



My suspects:

1) some desktop manager bugs, or other similar issue
2) video memory allocation - I'm still suspecting that it can be caused by the amount of RAM dedicated to the videocard, currently, I think that it is at 256MB.
3) some poorly designed components of Chrome/Scre... Read more

Hi everyone, I am trying to add a second HDD to my L540 using a caddy for the Ultrabay. The primary HDD is a Samsung 128GB SSD, 2,5", attached to the internal SATA3 port. The OS is  on the internal disk, and for various reasons I have no way to change this (why would I, anyway?).The interesting part comes when I insert the second disk and boot the machine, the boot manager chain (GRUB -> Smartcard login on a mini Linux system -> GRUB4DOS -> Windows)  fails to load windows and displays a blank screen. The reason is that the internal disk is seen by Windows and Linux alike to be attached to Bus Number 4, Target Id 0, LUN0, and the second disk is on Bus Number 0, Target Id 0, LUN0. Which basically means that the second disk is enumerated _before_ the internal disk, and the boot manager chain does not find the Windows OS that should be booted. Screenshots from Windows Device Manager: I played around with my own GRUB4DOS settings but I cannot make the system accept that the internal disk is the first disk. (The second disk works fine when I hot plug it after Windows boot but this is not a permanent solution...) Q: What makes the OSes (and the BIOS, I assume, which I can only view but not change due to a BIOS supervisor password) think that the internal disk should be enumerated second? Confused... Thank you for any insight!

I am trying to 'dual display' my L540 to my TV. I have a mini dvi port (or whatever it is!) converter plugged into that port with an HDMI lead plugged into that and then into an HDMI socket on my TV. I assumed this would then be dead easy to just select dual monitors or similar and the laptop output would be duplicated on the TV. However I'm not getting anything on the TV. Is there some other setting I need to change other than in Control Panel>All Control Panel Items>Display>Change Display Settings? Under Muliple Displays I select Duplicate these displays and Apply but all that happens is that the display resolution on the laptop goes really big ie nothing appears on my TV. It feels like the laptop is not even detecting anything attached to the mini DVI port - would this be driver related or is there something else I'm overlooking? Really want to fix this as I'm hoping to be able to play Youtube vids (with sound) from the laptop through the TV and maybe also Amazon movies. Any help gratefully received!!

I'm considering building an external GPU setup for my laptop (thinkpad L540), wanted to check if anyone had done it. I saw it listed on techinferno's list of candidate systems, so I'm assuming it is possible. Does the L540's PCI slot allow for this sort of thing (or might there be another way of doing it?)? I guess my main concern is that there's some aspect of that connection that won't support an eGPU and this whole thing would be a waste. Whether you've done it or not, any insight is appreciated!

Some of them do not have a camera installed, you should check the invoice or the label on the box for features included in the notebook you purchased.You can returned it to the store and get another one that has the features you wanted. Good luck.

it may be the Windows Media Center that you had used.  What I would do is right click on a file you know you have viewed using the particular application and select open with; this should offer you some choices to try.  If you find the right application next time right click on a file, select open with again and then select default program; this will set that app as the default for that file type.

I recently got a used thinkpad L540. The previous owner apparently had to redownload windows 10 while trying to change start up setting for using linux. I'm using windows 10 on it.I did the function (fn) and control key swap in BIOS and everything was working fine for a while, but one day, most of the hot keys stopped working whenever I have the function lock on (which I like to keep it on to use the usual function keys). For hot keys such as mute and lowering volume, whenever I press those keys with the function key (which is originally the control key, since I did fn-ctrl swap), to use the hot keys while on function lock, I get a beep sound and nothing happens. I have swapped the function key and control key back to how it was, and it wasn't a problem, but I really don't like the function and control key position in this laptop, and use the usual function keys often enough that this problems bothers me. Oh and there is no problems when I have the function lock off. I've tried downloading the keyboard driver for thinkpad, which it seems like this computer was missing, and this problems still continues

Having a problem tonight with the audio for my L540. Worked fine yesterday. Built in speakers (speaker/hp) work normally. However when trying to use headphones, ear buds, etc in the 3.5mm headphone/mic jack on the side, no sound is played through the headset. The computer/driver recognizes that there is a device plugged into the jack (displays RealtekHD Audio 2nd Output in sound/volume button on the taskbar) however still no sound.  I've checked everywhere I can think (volume mixer, device properties, driver properties, apps)  and it isn't muted anywhere. In the properties, it say the device is enabled, is working, however when you "test " sound, nothing plays. While the built in speakers are selected, the "test" sound works.  I have updated the driver, rolled it back, unistalled and reinstalled the software (from lenovo website) and the problem persists.  Thinking it is a power or physical issue with the port, I tested the microphone feature in the same port. The microphone works, picks up sound and records. So there is power to and from the port. That has left me scratching my head and searching for any solutions. I have gone into all of the programs, apps and games i used and checked the audio settings, nothing is muted or off.  Has anyone experienced this issue? Better yet has anyone fixed or have any ideas how to resolve? My intuition tells me there is somewhere im not looking that holds the answer. Thanks in advance... Read more

A:L540: No audio from 3.5mm headphone output.

1. Open the Control Panel and look for Realtek HD Audio's control panel.2. At the right top of the window you should see one or more plugs. Then plug in and unplug your headphones, see if the headphones are detected there.

Hi guys. I recently purchased a "Lenovo Thinkpad L540". I encountered an odd WARNING when I was reading its documentation. this WARNING is as following:
________________________________________________________
Notice for users in the U.S.A.Many personal computer products and accessories contain cords, cables or wires, such as power cords or cords to connect the accessory to a personal computer. If this product has such a cord, cable or wire, then the following warning applies:WARNING: Handling the cord on this product or cords associated with accessories sold with this product will expose you to lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm.

I got confused! Does this mean that every time I handle or touch my power cord, I should wash my hands? I have to tell that I live in IRAN. Do you guys know anything about this warning? pls explain it for me.
thanks a lot.

Hello everyone. I have recently got a new ThinkPad L540. Since I need to use Windows 7 (TrueCrypted company Installation on normal SSD) and Ubuntu I bought a HDD Caddy for the UltraBay together with a 1TB HDD. My problem is, that I can not select the second HDD (HDD1) in the BIOS to boot from. It does not show the name of the drive, just HDD1. HDD0 has a name that indicates that it is the Intel SSD. The new drive is visible and usable in Windows and when I use a USB-Drive to install Linux on that second Drive.Furthermore I switched the SSD and the HDD and the L540 boots sraight up into Ubuntu. When I switch back its boots Windows 7 again. During the Ubuntu installation I tried both, writing the GRUB2 bootloader to the root-partition or to the beginning of the HDD (schould be the same since the root-partition is the first on the drive). Gparted is also thelling me that the root-partition is bootable. I hope somebody has an idea!Thank you very much for your help in advance!!! 

A:L540 HDD in Ultrabay not recognised in BIOS

I have exactly the same problem . Bad solution is to change the AHCI to IDE mode in BIOS. Do you have an idea how to solve it?

Dear Community, my L540 lid cover has cracked (without any reason to do so...), as the manual suggests there are two versions for replacement: one for "slim LCD", one for the "wedge LCD". However, I can not find any hints on how to tell if I have the slim or the wedge version. The model version states "20AV-002WGE". Thanks in advance!

Just recently began having issues with my built in keyboard on my L540. It was very sudden this weekend, came to my computer after being away, and noticed my keyboard wouldnt work. Couldnt type, arrow keys, side numbers, top numbers. Strangely enough the command F keys up top for sound, screen brightness, etc did work. Then a little while later they too stopped.  I have a new keyboard in the mail now and will have it by the end of the week. However, just today my pointer and touchpad now will no long work either. Currently using usb for each.  I went through to uninstall/update drivers, tests, everything passes and yet the problem remains. I will be checking the internal ribbon connections soon to see if thats any cause. It's just strange how soon after my keyboard goes that my pointer and touchpad goes also. I havent had any drops, or liquid spills. Anyone had any similar issues?   On a side note. One dot im not sure i can connect to this problem, is a recent Windows 10 System update (Version 1511, KB3150513, ) and Cumulative update (KB3210721), along with some misc. security etc updates. If i remember correctly, i think i performed the updates because i was having keyboard issues. But it did not help, and has actually made boots slower.

I got my L540 with Windows 10 last December (2015).  Starting in March or so of 2016, my laptop's screen would go black (you can see some back-light so the monitor is functioning) and there is NO cursor. lIt started infrequently (once a week or so) and then worked it's way up to several times a day.Suspending (closing the lid or using the power button) and reactivating restores the system to where it was when the screen went darkSometimes, waiting 30 minutes or more would take me back to a functional machine.While the screen is dark, I can hear the fan and other noises from the laptop itself.I've disabled as many of the Windows apps as I can to see if it is app updating or some such thing.  But it's still happening. In addition, the screen will randomly "flash" or "blink" for reason I can detect. I found this thread for the Y50-70s:https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Lenovo-Y50-70-black-screen-at-random-times/m-p/... where Blue Screen Again wrote:"From what I've read here, it is probably some power supply to screen issue or bad LCD cable, might be completely wrong though." Does anyone have any suggestions for how I might determine whether this is a hardware or software issue? Thanks, in advance, for your time.
