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 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.

First of all, let me explain the problem from the beginning. When everything is normal on the computer in the morning, when I run the computer in the morning, the screen is black, but I noticed that the computer is working. When I look carefully, the screen is black, but I saw it. I saw the screen is distorted. I put the screen back on the screen and I saw that it was black. The screen was showing for fifteen minutes before but now it has not. The screen that I removed from the working computer is black screen and when I look carefully, something appears.

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, 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 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

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

Go to Settings/Personalization/Themes/Theme Settings and choose a different theme.

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. You can click the thumbs up icon to show gratitude! Thank you.

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

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.

Recently bought an old L540.Great machine in excellent condition. Original keyboard wasn't backlit, and the trackpad was the horrible one without the 3 buttons on top. I tried changing the keyboard (ebay one), and it works great.. Except the backlight.. Filing complaint to seller. However - the trackpad is what bothers me. I've installed win 10. The newest edition. 1803. The trackpad I bought is: https://www.ebay.com/itm/Trackpad-Touchpad-Three-Keys-Button-for-IBM-Lenovo-Thinkpad-L440-L540-L450-... The 3 buttons work.Pressing and dragging rarely works.Multitouch is not even an option. Like scrolling on the web using 2 or 3 fingers. I've searched everywhere for drivers for it. Newest ones, old ones, removing files, following guides. Jeez I worked hard. Still no solution. So my question stands:Have anyone had similar experience replacing the trackpad, and then making it work properly?The trackpad has a name: LEN2004 I'd love to name all the driver versions I've tried - but I exploded and decided to reinstall windows 10 completely, with the new trackpad installed as well. But once that's done, I will go through all the processes once more, in case no one has come up with some advice. I hope you can help me out - else I'll have to use the old original one. Regards Thomas

1866 RAM will probably work, but it will slow down to 1600 speeds. If I were you I would either play safe or make sure the vendor accepts returns in case it doesn't work.
 
Also avoid any "Value RAM" or "Value Select" modules, as well as any no-name brands.

I face a strange issue on a Lenovo T470 running Windows 10. The problem is when i open an excel spreadsheet, especially one with many tabs, and i drag it from the main display to the external monitor, Excel's cpu usage jumps from 5-8% to 50-60 %, and is not functioning properly. Cannot move from one cell to another, cannot scroll up and down. It is either very slow, or it totally crashes and i have to kill Excel. If i drag the file back to the main display, it works as expected. The issue occurs only when the external monitor is set up as extended monitor. If i set it up as duplicate monitor, it works fine.I tried removing and reinstalling the display driver and also tried disabling graphics hardware acceleration, but no luck. And this happens only with excel, no other application. A newer version of the driver is available from Intel, but when i try to install it says that it is not certified for the specific model and i should contact the vendor. Computer specs:- Lenovo T470- i5 7300U- 16 GB RAM- Windows 10 Enterprise Build 15063- Intel HD Graphics 620- Secondary monitor is connected either through HDMI or through an HDMI to VGA adapter.

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!

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 purchased an L540 with Windows 7 Professional pre-installed in 2014.  Currently I have version 6.1 (Build 7601 Service Pack 1), and am NOT having any technical issues.  However, my SquareTrade extended warranty expires soon (in October), and I have been wondering if I should upgrade to Windows 10 (probably along with the Classic Shell app).  Just browsing the forum, I see a number of posts that reflect various issues with upgrading to Windows 10, and can't really tell if those issues have been resolved by now.  I know that Microsoft plans to support Windows 7 Professional until January 2020, by which time by laptop will be 6 years old.  Any advice on whether it is worthwhile to upgrade and comments on the cost/difficulty of the process?

So I got 2x8gb of RAM, my L440 came with 4. I took out the 4gb slot and put the first 8gb stick on there. My problem is that I can't put on the second RAM stick. The RAM pins dont slide in like the first one. I try to lightly push it in but It doesnt slide in the slot. Am I doing something wrong? Where exactly are the pins supposed to go?  

A:L440/L540 second ram slot

Hello Mui, welcome to the community,
 
there are two slots, one on top of the other, on the L440.  When inserting RAM you need to ensure that you initially position and insert the module at an angle of about 20° to the slot and then push it down into place.  See p74 (pdf p80) of the Harware Maintenance Manual.
 
If needs require I'm sure you will loads of video tutorials on YouTube.  And please don't forget to let us know how you got on.

Trying to update the BIOS past 1.88.  Update is available with System Update and the web but it will not install.  Checked the BIOS and it allows updating.  Tried downloading both options from lenovo support as well (OSI and FLASH).  Neither worked.  Im wondering if it is my machine or the software.  Trying to secure against Spectra on this thing and need the March update to do it.  AHH!

Would anyone from Lenovo be able to give me the 'supplier part number' for an 8GB DRAM or DDR DIMM that works with this L440 Laptop - Type 20ASS06Y00 S/N R9****** ?

03X6657 is the Lenovo part number.  That corresponds to several manufacturers' part numbers off various brands.
 
If you are buying non-Lenovo-branded RAM, you need DDR3L (1.35v) 1600 mHz SODIMM.  It might be described as PC3-12800.  Avoid RAM labeled Value Ram.  I always suggest checking return policy on RAM before buying.  Everybody has their favorite brands.  If I am buying RAM for myself, I like Corsair Vengeance.  I have never had a failure or a compatibility problem.

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 have a L540 Thinkpad. I recently had the dvd writer stop working on this unit. Now, yesterday I closed the lid with the laptop powered up, as I have done many times. When I went to open the lid and continue using it, the backlight on the screen comes on but nothing else. Also, when I connect an external monitor, it works perfectly. What might be my issue?

If the screen is white (backlight only) the problem is usually s disconnected or broken cable

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

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.

I just bought an L540 and was using it to view some videos that I had downloaded.  The application had a broad black band across the bottom of the screen, including a "Screen Cast" button on the left.  It shows the elapsed time on one side of the slider, and the remaining time on the other side.  I rather liked it. Last night I was presented with the Windows Media Player interface which I don't like nearly as much. Does anybody know what app this is, or how I reset it to the default.

A:Default media player L540

Hi Hodag,
 
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.

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!!!

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?
