Lenovo 11e E/Edge :: E540 - Can Disable Discrete Gpu (Optimus) From BIOS?
Jul 15, 2014
I'm thinking of buying a Thinkpad E540 with a discrete nvidia gpu. I am planning to install linux on it and I don't really need optimus for it (nor is it well supported) but I'd like to occasionally be able to use it on windows.
I'd like to know if it's possible to completely turn off the nvidia gpu from the BIOS so it works only with the integrated intel one or should I buy one with intel gpu only.
I have read that the lenovo changed the dual gpu implementation on the latest generation thinkpads.
I have an E540 and today I spilled some liquid on the trackpad and now my cursor is moving around and clicking randomly. I use a mouse so I don't need the trackpad.
I've read online how to disable the trackpad but I don't have any of those options. Like disabling it in BIOS or in the driver(Control Panel -> Mouse) - I just have uninstall. If I uninstall windows 8.1 will just automatically reinstall it after reboot.
I have purchased E540 and I have purchased Norton Internet security but the system does not load the installation when I insert the disc. I have tried the run command as well as other options like choosing the file from the disk in the windows explorer but still my system can not load the setup!
I just purchased the E540. Running Win 7.1. I have 2 WD 3.0 Passport drives plugged into a USB 3.0 hub. The 3.0 hub has the correct cable for 3.0. They are not being recognized as 3.0 devices (I get a message). I updated the USB 3.0 driver on lenovo's site and BIOS is set to auto.recognize. I have also tried the 3.0 option in the BIOS but that didn't do anything. I also tried using the drives without the hub in one of the 3.0 USB slots but that didn't do anything either.
I have checked the forum but what I found was possibly purchasing a 3.0 cable (not necessary - my cable is 3.0 compliant) but that was for a Wn 8 system or updating 3.0 device driver (done). So much for plug and play.
The fan in my e540 does not stop once it has started spinning. This is completely independent of system temperature. Even though the temperature of the board and the cpu is below 40*C the fan won't stop.
The fan does not always spin, though. If I wake up the system from sleep or power it on, the fan does not spin and will not start spinning until a certain temperature threshold is reached. This part of fan control works correctly.
Interesting procedure: I work until the system gets hot and the fan kicks off. I want until the system is cooled down below 40*C (checked with speccy software, the air stream leaving the notebook is cold). The fan is still spinning at this point and will probably spin forever. I suspend the laptop (no complete power off required). I immediately "wake up" the laptop (system temperature did not change, no time to cool down). The fan is off again and will not start spinning until the temperature threshold is reached.
I encountered this problem today when i tried to scroll up a website and it simple didn't scrolled up so I tested it in some other programs to make sure it isnt just the scrolling. Then I booted into bios and the key works there fine and when windows started up the key was working for brief moment and then stopped working.
That points toward some program that might be doing it but I don't have a clue which one.
I have recently purchased a Lenovo ThinkPad Edge E540, with Windows 7 installed. I'm trying to use the integrated camera with Skype, but I can record no picture. When I try to install the Integrated Camera Driver from Lenovo Support, [UR], the setup always fails with Engrish error messages.
Can any E440 and E540 owners confirm whether these laptops feature the ability to remap the Fn and Ctrl keys? I understand a BIOS setting provides this function on previous E-series models, but haven't found information specific to the newer models that confirms this setting is present.
I have bought my new E540 some days ago. My keyboard is Norwegian so there is a key called AltGr available which is used as a combinational key similar to shift. when I just press the key related to backslash ( it's '+') it works fine but when I want to type backslash (it's AltGr and '+' together) it does not work.
I added a second drive (SSD) successfully to the E540, everything works and is set up properly. I still have the original HDD in place and got Windows 8.1 (x64) installed on both drives. However, I cannot run Dolby Advanced Audio v2 when booting from the (fresh) Windows installation on the SSD. Right after booting or trying to start the application there is a Windows error message telling me that the Dolby-driver cannot be run and I should reinstall the application if the error continues to exist.
When booting from the original HDD there is no problem with Dolby Advanced Audio v2, the application just works fine. Whenever booting from SSD the error message comes up.
I know that this is a known issue and I've read all the information that is out there on the internet. I tried uninstalling and reinstalling from the DRIVERS folder on C: multiple times, installed everything in different orders and tried almost every combination of using the SETUP in AUDIO, the SETUP in DOLBY, the UIUa64 and so on. I can't install Dolby Advanced Audio v2 on the new SSD properly. The installation finishes and Dolby Advanced Audio v2 is shown in the list of installed programs, but immediately after finishing the installation the error message also occurs.
(I exactly followed the reported solutions for other systems, but none of them worked for me. In which order I have to run the driver setup(s) for my E540 if you think this is a possible error source.) I really do not know what could cause the error message while the (seemingly) exact installation still works while booting from the original HDD?
(I am not referring to Dolby Digital Plus but Advanced Audio v2! The Dolby Digital Plus user interface is accessible on SSD. The sound quality varies tremendously between the two Windows installations on HDD and SSD and the loss of sound quality is unacceptable for me.)
I uninstalled and reinstalled (automatically by Windows 8.1) the mic and it's no change. I try to chat over Skype but people barely understand what I am saying. I tested it with other apps apart from Skype and it's the same issue.
Today I received my brand-new E540 from Amazon. Upon inserting the battery and starting the laptop for the very first time, I was greeted by the following error message:
The battery installed is not supported by this system and will not charge. Please replace the battery with the correct Lenovo battery for this system. Press the ESC key to continue.
The message has only appeared once and hasn't been shown on subsequent reboots.
I proceeded to install Windows 7 which worked fine. Under Windows the battery symbol in the taskbar would say "66%. Plugged in. Not charging". I then shutdown the system and re-inserted the battery. Since then the battery appears to be charging normally and when I inspect the battery symbol in Windows it says something like "89% charged. Plugged in. Charging."
Seeing how this is a brand-new laptop, do you think the battery is broken and I should return the laptop, or should I keep it since it seems to be working normally now.
I have recently bought ThinkPad E540 with OneLink Pro Dock, in which I have connected my LG Flatron IPS236 external display. LG's max resolution is Full HD 1920x1080, but for some reason my external display's max resolution is only 1280x1024. The display is attached to the OneLink Pro Dock's DVI port. I have both updated the graphic card's drivers and LG monitor's drivers and booted the system. I have also tried using both 75 hertz and 60 hertz refresh rates.
There are a few configurations of L440 laptops with Nvidia GT 720M grafic cards and Optimus (e. g. 20ASS01G00). Is it possible to change the used graphic system in the BIOS (Intel only/NVidia only/Optimus)? And which card is hardwired to the external ports (VGA, mDP)?
(Do this differ from the T440p or the Edge Series, E540?)
I am new to having a thinkpad and I know that my system has a the intigrated graphics and the discrete nvidia nvs 3100m Optimus card. Here is the issue though. I have been trying to run some programs that are more video oriented (gaming). I discovered that my system is only reading the intigrated graphics and doesn't even acknowledge that the nvidia card is there.
I have updated to the latest drivers and checked the Bios to make sure things are there. Sadly they are not. I looked at the bios, followed the directions I found on the forum to set that to card to on only to find that the the only card it recognizes is the intigrated graphics. So the question is, how do I get the bios and the computer in general to recognize the nvidia card on my T410 (2522)?
I've recently purchases a Lenovo ThinkPad Edge 540 and it worked just fine untill earlyer today.While i was browsing the internet, some how my touchpad developed a problem.It only registeres right click where ever i click.I've deleted the drivers, even tho they were the knewest ones, downloaded a fresh .exe and installed it after the reset and what not and it still has the same problem.
If i turn off the touchpad in the ultranav software and enable only trackapad, the buttons work like they should, the large area in the touchpad registeres as the left click and the small area in the top right is registered as the right click. Tho i can't use the touchpad for navigation.So clicking doesn't works, well neither does tapping. I can doubletap normaly, but i cannot tap and drag such as selecting a block of text.
Again, i've already tried a fresh install of ultranav drivers and it didn't work. The problem manifested itself during normal browsing, nothing was installed nor changed hardware vise. It litteraly changed in a second.how to solve it since the driver reinstall didn't work.
I was originally under the impression that my laptop (Thinkpad T510 4384-DS9) had NVIDIA Optimus display technology, however, I cannot find any OPTIMUS options in the BIOS under display (or any other section for that matter).
The reason I would like to know is that I have recently purchased a docking station (model: 4338) and 3 external monitors which I would like to use simultaneously.
Forgetting the fact that I'm using Linux, and that for most people this wouldn’t be a challenge worth undertaking, I would just like to know if my system actually supports 3 external monitors and the laptop screen concurrently using the docking station.
I have an E420, I use the functions keys F1-F12 100 times more than I do for volume, monitor, etc. I find it annoying and frustrating that when I do decide I want to change the volume I always get a pop that prompts me to change the behavior. How can I disable this annoying popup without losing the special key functionality?
Just a got a brand new Thinkpad 540-E. So far this CPU runs like a beast(with a new SSD installed). I have one minor issue though...
GOAL:: Make the F1-F12 keys function without having to press Fn first.
So I've tried the three tips I've come across online. Here is what happens:
1. BIOS(ThinkpadSetup): I only get the option to switch the Fn and Ctrl key. There are no option in my BIOS to do anything else with the keyboard/mouse settings.
2. Holding down the Fn key for 30 sec to 1 minute: Nothing happens. I even tried to do a three minute press and hold. I had a blast, but nothing came out of that neither.
3. Entering the keyboard settings in Win 7 manually: So I have no trouble entering the keyboard settings window, but mine looks extremely limited. In fact I see no options to do anything in there besides updating the driver.
I have Lenovo Thinkpad Edge 15... Thinkpad edge 15 has all kinds of buttons on the keyboard. Like volume buttons, speaker mute button etc.
The problem is that there is a button for Webcam to disable/enable it (marked with yellow box on the pic), but its not working anymore. Everytime i push it, nothing happens(instead it shows me mouse cursor with that ring) . it should show me that camera is on/off. For example it shows me when my mic is off.
I just bought an Edge 130 and wanted to set it up today. But I just can't enter the BIOS! I keep pressing F1 during the Lenovo splash screen. I've pressed it repeatedly, held it down, I even tried it with the Fn button pressed. Nothing worked.
I've have been working with and professionally supporting Lenovo (and before IBM) notebooks for over 10 years and not once did I have such a problem. This is only the second E-series notebook I have ever had. I bought myself an E525 last summer and had no such problems and at work we have T-, X- and W-series.
