Lenovo Z400 P/Y/Z Series :: Completely Disabling NVIDIA GPU
May 22, 2014
how the Intel HD Graphics 4000 is covering all my needs perfectly for the moment, I would prefer to disable the NVIDIA dedicated GPU in my Lenovo Z400 for a while.I've already went to the control panel and set the Global Settings for integrated but it still turns on (for a very small amount of time) every now and then.
From my research I would guess I would do it by: (Windows 8)Disabling the "NVIDIA GeForce GT 635M" driver in the Device ManagerSwitching from "Switchable Graphics" to "UMA Graphics" in the UEFI settingsI would like to know/confirm if:"UMA Graphics" means the Intel HD Graphics 4000 in my caseThe NVIDIA GPU will not actually turn on and generate heat/consume energy.
Laptop: ideapad Z400
OS: Windows 8.1 (64 bit)
CPU: Intel i7-3520m (w/ Intel HD 4000)
GPU: NVIDIA GeForce 635m
RAM: 8GB @ 800 Mhz

I have an IdeaPad Y580, and I want to disable the Nvidia chip in the BIOS (I run Linux on it and don't use the chip.) I have the BIOS updated to the latest version from Lenovo's website. I couldn't seem to find anything in the BIOS settings that would allow me to just use the Intel HD 4000 graphics. There was an option to change from "Switchable" graphics to "UMA" graphics, but from my understanding the UMA option means using the CPU to process graphics instead of even the Intel integrated.
Is there any way to turn off the Nvidia chip, or am I stuck with it being on?

if it's possible to disable the Intel card completely and use NVIDIA directly through BIOS?
I'm trying to use Nvidia Nsight to debug shaders in OpenGL but Optimus/Switchable Graphics make things difficult for Nsight.At his point BIOS has just UMA and Switchable Graphics as options.But I've seen other laptops with a discrete graphics option.Is this model hardcoded to go through the Intel card anyway?Is there some other BIOS version that can add the option?

About 2 weeks ago, my z400 automatically updated from windows 8 to windows 8.1. i have been read reviews on whether or not to restore my computer to its original state or continue with 8.1.i have noticed several malfunctions in my unit after the upgrade and quite frankly i am really hesitant on continuing with 8.1.

I bought my lenovo z400 ideapad beginning of April this year and just about two days ago it just turned off and though I plugged it in later it started saying 'plugged in but not charging'. What do you think is the problem?
Furthermore I lost the receipt ( the sales receipt) but there is still the model/series no. , is the warranty still on?

I don't want to use the BIOS update method because I think it will make my computer not working anymore.
How do I press [F1], [F2], [F3], [F4], [F5], [F6], [F7], [F8], [F9], [F10], [F11] and [F12] without everytime pressing [Fn] to use these keys. So the original keys are: [Mute], [Vol-], [Vol+], [Close], [Refresh], [Touchpad], [Airplane] [Apps], [Screen], [Projector], [Bright-] and [Bright+], I want them to be: [F1], [F2], [F3], [F4], [F5], [F6], [F7], [F8], [F9], [F10], [F11] and [F12], and when you press [Fn] they be: [Mute], [Vol-], [Vol+], [Close], [Refresh], [Touchpad], [Airplane] [Apps], [Screen], [Projector], [Bright-] and [Bright+].

So since I've bought this computer I've had problems with the two-finger scrolling suddenly stopping, like many people have. That's always been fixable by going into properties, device settings, settings, unchecking/rechecking one of the boxes under "two finger scrolling" and hitting OK.
Now, though, my touchpad is suddenly stuck on one finger scrolling, and it's super annoying. There is no "one finger scrolling" option under the "scrolling" drop down thingy under device settings, so I haven't a clue why this is happening. I've tried the usual fix above, restarting the computer, installing new drivers, but it still does one finger scrolling. Which means it scrolls a lot of the time when I don't want it to, and the pointer seems to get "stuck" at times when I'm just trying to move it around.

I would like to ask about the Lenovo Energy Management software bundled with my Z400. Regarding the Energy Management > Battery > "Optimized Battery Health" in particular. When the battery charges until 60%, does it internally disconnect the charger from my battery? The Power icon in the System Tray says "Plugged in, not charging". Or does the software stops the charging until 60%, and when it lowers the software allows it to recharge again? I'm worried about getting my battery worn out immediately, as I leave my charger plugged in most of the time.

I am trying to disable UEFI Secure Boot on my Thinkpad Yoga S1 but it keeps getting re-enabled after a reboot. If I set secure boot to disabled I can boot into the non secure OSes installed on the machine imediately afterwards but if the machine is restarted the Secure Boot seting in the BIOS is re-enabled. It's important for me to have secure boot disabled as I use OSes without secure boot.
I try to disable Secure Boot in the BIOS on the following screen :
Link to image 1
But if I re-enter the BIOS either after booting into an OS or simply re-entering the BIOS, Secure Boot is back on:
Link to image 2
I have also tried to disable "OS Optimzed Defaults" but it also returns to enabled after a restart.
Link to image 3
Some of the other BIOS settings save correctly so I can't figure out why the secure boot settings don't. The BIOS version I have is the latest (1.18).
It's inconvenient to manually disable secure boot each time I want to use the laptop. The two operating systems (Ubuntu and Android x86) do work reasonably well once booted.

Initially configuration was easy (through available connections)and i could use net at ease. Bue couple of days I happened to "Disable" two network which used to connect automatically the moment i used to turn my laptop ON.But after that, I never saw them in the available connection. Although i can see those network available on my phone, but on laptop i unable to detect them. I tried configuring them by using "wireless network connection properties" and i could even chnage their preference too. I tried disabling/enabling wireless network, but its not working at all.But at the same time I can see coupls of other wireless network which are in range, but i can not connect to any of those as they dont belong to my hotel.

Is there anyway to disable the center scroll button on the x-240 trackpad. I keep hitting it when I try to use the left mouse button. I never use the scroll button and want to get rid of it. The new trackpad's design is horrible with the undefined buttons.

I've had the laptop since last Friday. I've updated drivers and have been installing a few games on the device.
I've been installing a ton of games the past two days while I'm at school (great download speeds from steam and origin) and have been having issues when I try to run said games.
The laptop has a SLI setup with the GT 755M. I've noticed that when I've tried to game lately on the laptop that I've had pretty poor luck. Games seem to crash with frequency, with only a few different times that I thought had narrowed down to SLI being enabled or Anti-Aliasing, but after it crashing a few minutes ago not long after getting into a Team Fortress 2 server, I now don't think that is the case.
What might cause this? I have the battery removed at the present since it's Nearly charged and seems pointless for me to leave it in while I'm running off the 170W adaptor. Could this be an issue where the adaptor doesn't supply enough power and needs to draw additional power?
I don't feel that heat or anything else like that could be the cause because there's no warming and the system powers back up just fine. I'm going to re-attempt to play a few games that crashed immediately (Battlefield 3) and see if this changes anything. I love the laptop otherwise and really hope that this isn't and indicator of a more serious issues.

Is there any way to completely disable the touchpad and trackpoint on the X1 Carbon without going into bios?
I am able to disable touchpad OR trackpoint by going into mouse properties in control panel but it won't let me do both. I would like to turn it back on relatively easily if possible.
I am trying to do this on a work computer and I have no administrative rights and I am using Windows 7 Professional.
Can this be done or did Lenovo completely overlook such a simple feature?

Before the end of 2013 I bought an Ideapad U530 Touch for school and it's been working fine up until a few days ago when the backlight for the left most CTRL key stopped working and shut off completely. Every other key on the board is fine, except for this one. Is there any easy to fix to this problem, or do I need to send the entire computer back?

I knew that the Nvidia GPU triggered only when a 3D graphics heavy application is loaded. It is. But I only get a bad 3D rating (1 star or so) while playing the game.
I've configured the Nvidia 3D program setting and also on a high performance battery plan. The Nvidia notification icon tray is also show that the game is loaded using the Nvidia GPU.
On other hand, when the laptop is plugged in, I get a best 3D rating on the same game. How is it possible?
It is not comfortable due to the fact that I have to plug in the laptop whenever I want to play the game to get the best performance.

I rencently reinstalled windows 7 on my W520 and it refuses to activate my nvidia quadro 2000m (Code 43).
For a while the fan is overheating and the right left hinge become very hot. I think the graphic card is dead but I want to know why and if I can stop the overheating. Is the the graphic card soldered onto the motherboard of the W520?
Only the Intel HD graphic chipset is running ...

On my T410 , at the front RHS of the keyboard, there's the group of Left, Up, Right and Down keys.
Each side of the Up key are two keys wih sort of browser page icons on them which I find extremely annoying because it's so easy to touch them by mistake while typing and have the browser (FF 30.0) abandon the current page and go somehere else.
After googling around this problem, I've downloaded and installed the TpKMapAp utility. However, on the KeySensitivity tab, the checkbox "Enable Browser Keys", which I assume refers to these two keys (seems to be confirmed by the results of the test on that tab), is not checked.
So, why do these two buttons still work and what else can I do to prevent them?
Fwiw, I made a registry change google found me to disable the Windows key two left from the space bar, which I found as annoying as these two browser keys. Is there a similar one for them?
And finally, a question for the TP designers: Why don't you provide a simple way to turn keys like these ones off, rather than relying on undocumented registry hacks and utilities that don't come supplied with the machine and, in the case of the browser keys, don't work anyway.

I just got my T440s a couple of weeks ago. I stupidly ordered it with only 4GB of RAM, thinking that I couple upgrade it myself if neccessary (and it would be much cheaper that way).
Well it seems 4GB definately isn't enough for my needs, so I ordered another 4GB stick. I installed it, plugged the machine in and powered it up. And was met with the tone for a memory error. Probably the module isn't seated correctly, but I suppose it could be faulty.
Anyway, you'll notice I said that I plugged it in before powering up. That means that the internal battery has been reactivated. I can confirm this because it will start (and give me the error) without being plugged in and without the external battery connected. So my problem is, how do I disable the internal battery again to remove or reseat the problem DIMM, since I can't get to the UEFI/BIOS configuration to disable it.

Sometimes when I leave my Helix alone the screen saver kick in. When I try to use the Laptop again after a while, it has turned on the (back) camera and the camera app is completely stuck. No swipe, no Alt-F4 or Alt tab can get it out of there. I have to hold the powerbutton down for a hard-power off.
Seems to me this is a software problem. I tried to install the new Settings app this morning. (this refreshes the camera sw and other drivers) but no improvements. Same problem remains.

I've been eyeing a Vaio Z-series (555 or the the 590 online-only in Canada) but I want to make absolutely sure that it contains a nVidia card (9300M GS 256MB).
When I go to the stores to look at the store model (Sony store & Best Buy), in Device Manager and Display setting, I only see the Intel Mobile graphics chips. No where on the system does it appear to say that it contains a nVidia card. I tried using the Stamina/Speed slider to see if there was a different (setting it to Speed), and the graphics card still says INTEL.
For all those who own a laptop from this series, what do you see?
Do *all* Vaio Z-series have a nVidia or only certain ones? Is it just a driver/software issue for the ones at the stores?

Why is Dell still selling notebooks with Nvidia GeForce 8000M Series such as the XPS M1730?
They know the GPU is defective and will fail far sooner than it is intended to. They are selling a ticking time bomb.
I know that they release a BIOS update but that will only delay the eventual break down a bit later after the standard warranty expires.

Having geforce go 7900 gs 256 Mb (17 inch, 1920x1200) died after 2 years of using it, but played only moderately. I noticed sometimes GPU was over 80 C. No more warranty, so I plan on getting a replacement.
7900 gs is 20 Watt current consumption. There are cards like 7900 GTX, FX2500M tht have 45 Watt. So roughly we could expect twice as much heat made if replaced to a 45 Watt card. Am I right here? Now, even 20 Watt card (7900 GS) was overheating with only single heat pipe. 7900 GTX or FX2500 would have to have for sure 2 heat pipes, but since we have twice as much heat, do we have the same situation?
What is your experience with 45 Watt video cards in Inspiron E1705 / 9400 ? Do they overheat (and break) as often as 20 Watt and single pipe cards?
And second question - reliability of refurbished cards or "working pulls" How long can they last? I know it all depends, how the previous owner was using it, etc. When buying used card, what possibly was overheated more? 20 Watt single pipe or 45 Watt dual pipe (like the question above)
I would appreciate any oppinion and experiences from you.
In the future, I plan to better take care of cooling, remove dust more often, use AS5 paste, fan control, use dual pipe. Anything else can be done? Maybe going to 20 Watt with 2 pipes - would probably cool down system the best.

I recently got a Dell Precision M4300 from a friend and had a few questions.
When i got the laptop, I reformatted the Laptop and Reinstalled Windows XP Pro SP2. I proceeded from Microsoft to Update to SP3 and so on.
Well I also Went to Dell's Website and downloaded all the necessary drivers (using the service tag) for this laptop and installed them.
Now here is where I ran into a problem,
When I installed the NVIDIA drivers for the NVidia Quadro FX 360M video card, everything seemed to go fine. Then I rebooted the Laptop, and now every time I reboot, my hardware acceleration is defaulted back to None, and it gives me multiple pop ups about this issue. I go into the settings and turn the Acceleration back to full and it goes away.
This is a major problem, and is really frustrating to deal with everytime the laptop is booted up.
My other problem, is when I open up Internet Explorer, It tends to lock up the browser for no reason when Loading a website. I then CTRL+ALT+DEL and attempt to close iexplore.exe via the task manager. It closes the browser but does not shut down the browser, making it impossible to browse, so then I have to reboot.
here are the specs of the PC, from the device manager and drivers I have gotten
Dell Precision M4300
NVidia Quadro FX 360M 512mb Video Graphics Card
TSST 8x dvd+-R burner
120GB Hard Drive
3.5GB of Ram

Does anyone know how to disable the infrared sensor on an XPS 1645?
I ask as I often use the laptop while also watching a media pc and the remote control operates both the laptop as well as the media pc and it's damned annoying.
All of the items referring to the infrared receiver in the device manager can't be disabled so other than sticking a piece of tape over the sensor does anyone have any ideas?
