Lenovo P/Y/Z Series :: Y570 Physically Disabled Optimus Switch
Jun 17, 2014
I have a problem with my laptop Lenovo y570. I had a defective disk. After repair and return from warranty service, the Optimus switch on the right side of the notebook blocked or broken. I don't know. The computer used both graphics cards, but after installing the latest drivers works only integrated graphics. It seems that the Optimus switched, but I do not know how to switch it back when it is blocked. I tried install older driver and driver from recoverydisk for both GPU

I have reinstalled the drivers for the Nvidia card and now I no longer see the icon in "hidden" icons of the bar, that showed which programs are using this card.

So in the past couple of days I've noticed that my Y570 isn't charging properly.
With normal use such as internet browsing, facebook, e-mail, etc. there is no problem. However I often use my computer to game stuff like Don't Starve, League, CSGO, etc. So I'm thinking the problems is something to due with heat.

The fan on my IdeaPad Y570 has suddenly stopped switching on. It does not spin regardless of temperature, and as a result, temperatures reach 90C+. The dedusting mode works fine, the fan spins up as expected for the cycle, and sounds normal. So the fan is not physically broken or clogged. I have also installed 3rd party software CPUID HWMonitor to check if the temperature sensors are functioning, and they all show temperatures at expected levels, and more than high enough to warrant the fan coming on.
I don't think I have installed any new software that might interfere with it. I have tried re-installing the Lenovo Energy Management software. I have also tried starting the laptop in safe mode, to no effect.

If the laptop is no load and the temperature of 45-50 С (Celsius) (113-122 F)
But if you include the game, can be heated to 65-70 C (149-158 F)
Is this normal? should be lubricated with a laptop?

I'm currently using Acer Aspire V5-573G, which uses Nvidia GT750M.
Whenever I run games or graphics-intensive program such as the adobe premier pro, the program will continue to run using the Intel HD graphics and not the Nvidia driver.
I've tried changing the settings in the Nvidia control panel to use Nvidia graphics driver for all programs, but running the optimus tool will show me that the Nvidia GPU is not being used for any of the programs.

Overnight, my Z470's wifi stopped work. The switch nor FN seems to turn the wifi on again, but I dont think the device is damaged or something. I tried everything I could.
1) Update driver / Uninstall and update driver / delete and update driver
2) Try to work on WLAN in services.msc but I couldn't find it in there
3) Some people says that could be the power management, I'm still trying to find the compatible version.
So, what else can I do? I don't wanna to format my machine!
I'm using Windows 8.1

I've had this continual problem with my W520, which I can't seem to solve. Windows Search is disabled, I go into services, set it back to Automatic and start the service. It works fine all day long, no problems. When I shut off the machine, sometimes, not everytime, when I bring the machine back up, the service is now disabled and I go through this entire process again. What is strange is that at other times, after reboot, it is still enabled.
I've checked the event log, there is only an entry that indicates that the service was disabled, but there is no information in there which indicates the process that did the disable.
Here are the specs of the machine which might be relevant:
Hardware
W520
x64 Win7 Ultimate - standard Windows build
2820QM processor
16 GB RAM
1x500 GB drive in the HDD bay
1x750 GB drive in the Ultrabay (with the annoying gap)
Software
MS Office 2010
Visual Studio 2008/2010
SQL Server 2005/2008
ESET NOD32
Quickbooks
Chrome
othr related items for development.....
On the software side, I tend to keep it light, thus making it quicker and less likely to have conflicts.
Is there any tool out there which can tell me what process keeps disabling this service? It is very frustrating, having to go through this all the time. I know there will be some that say it slows down your machine, that may be their experience, but it is not mine and that penalty is outweighed by the convenience of being able to quickly search a 6GB email account.

One month ago I bought a Lenovo B5400 MB825GE with Windows 8.1 and I'm quite happy with it. The only problem I have got is, that the notebook won't change the audio output - automatically and most of the time even manually - from the speakers to the headphone, when plugged in.
I can "change" the output in the Windows "Sound" options but the problem here is, that it won't really work. I have got two devices in here, the first is the "Speaker/Headphone" which only represents the speaker. The second is the "Realtek HD Audio 2nd output" which means to be for the headphone. I have changed them to "default device" and to "default communication device" but the output won't change.
E.g.: Somehow (I'm really not sure how) I managed to change the audio output to the headphone. If I plug it out now, the audio output won't change to the speakers even if I change it in the Windows "Sound" option.

Thinking of buying a S410P i7 - but the whole series only offers 4GB RAM in one slot - so does the S410P support more RAM, if I switch it to 8GB for example?

Bought a unit with this problem: As soon as I unplug the AC Cord from the laptop, it power off without notice and can't power up the laptop. It seems like the battery is not giving power .When I plug back in the AC, I can press the power button.
One strange thing is that the battery is 100%, state : good. Tried the reset battery so now 3 cycle counts. The thing is that if I unplug the AC cord only from the power outlet to the ac adaptor then the power is still up, the brightness goes down a bit and then power off without notice.
Tried:
- the battery pack switch
- removed battery backup
- removed and reset the battery pack
I'm out of options and I would be glad if I can find what cause that "unswitchable thing".

Just bought the M5400 and plan to switch to a smaller SSD.
Checking up on the existing 500 GB drive from WD, I see that there are 5 partitions on it.
What really bothers me is all the wasted space each partition seems to have.
WINRE_DRV - 1000MB unused 675MB
SYSTEM_DRV - 260MB unused 200MB
Other - 128MB no unused
C:Windows...well here its obviously not an issue
Lenovo_Recovery - 17GB unused 8,5GB
there is almost 10GB of waste when I'm planing on switching to a 250GB.
Can I make theme smaller with Minitool Partition Wizard before I try cloning to SSD?

I have an X240, latest BIOS as of today, 2.21.1.12. FnLk gets disabled when the laptop comes back from so-called Deep Sleep mode.
This problem is also described in the T400/T500 section and there is a work around posted : disable Deep Sleep (30 Day Standby) in Lenovo Settings app in Metro UI.

I have since a few days my Power managment driver which doesn't recognize the battery any more.I have checked in the Windows Device Manager, which says: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)".Can it be related to a very recent Windows update I have made? (I'm on Windows 8.1)

I have just bought the G500 and I'm getting really annoyed by the keyboard. It has "great" multimedia keys as the main keys instead of usual F1-F12 keys. To access their functionality you must press Fn+appropriate key. The problem has been described here many times. But no solution works for G500.
I have tried: enter BIOS (no such option for keyboard)install Lenovo Slim USB Keyboard application (runs, but the option selected have no effect)install Lenovo Ultraslim Plus Wireless Keyboard & Mouse Driver application (do not run at all - just brings me to the desktop and do nothing). I'm not able to use the computer since I use a lot of application depending on the functional keys and if there is no solution I will have to buy another computer...

I've bought a B590 and installed a Win 7 64bit. I have installed all available drivers from the support page and have the following issue:
Device Manager:
I see 2 graphics devices
Intel HD Graphics
NVIDIA GeForce GT 720M
The discrete card is disabled with error code 43 and has an exclamation mark near it [URL] .... Moreover, if i start the NVidia Control Panel it gives me an error with text: "current display is not connected to nvidia GP" GeFoerce Experience is not starting with a back-end error [URL] ...
Now here are the ways i tried to use but it did not work:
1. Enable high performance and update with manually downloaded nvidia driver
2. Do the same with HDMI cble connected to a plasma
3. Disable enable the device (screen goes black, than to normal and everything stays the same)
4. Format c: reinstall Win8.1 64 and install all drivers - same thing
5. Format c: reinstall Win7 64 and install the graphics drivers after everything else (h1d9d9.exe h2d903.exe)
6. Update GT720M drivers from device manager (driver is up to date)
7. Run a high-performance 3D game (War Thunder) - it uses Intel HD
What else can i do? I saw people with switchable graphics use some kind of application to specify the game-apps that should use a discrete videocard. I don't have such an app to specify my games.

Recently I installed Windows 8.1 instead of Win7 on my IdeaPad S205. The problem is that the new Lenovo Energy Management tool doesn't let me swith the mode "Best Battery Heath". Everytime I click on it, it is automatically switched back on the "Maximum Battery Life" setting.
I also didn't find any tool where I can set my preferences (Best Battery Healt as standard). I have never had this problem on Windows 7.

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 ...

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'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 just bought a new W540 and it's almost impossible to work with common software packages that heavily use F1-F12. Every time I want to use the F1-F12 keys, I have to press also the Fn key. For me this is a problematic change from my previous T510 machine...
Is there a way to swap the default behavior of the multimedia keys with the F1-F12 legacy keys?

I recently purchased my new notebook (Lenovo T440p) which comes with OPTIMUS integrated Intel graphic card coupled by GeForce GT 730M 1GB. I tried to play some games; however for some reason in game options show, that my Intel HD card is being used as a default graphic card. This suggests that OPTIMUS technology is not switching the graphic card properly. System running on windows 8.1 Pro 64bit. How to enable Optimus switching?

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 got a 370 bluetooth card and for the life of me I can't figure out how to install it in my Studio 15 even after reading the directions on Dell's website. First of all did they send me the right card it measures something like 1/2" by 1 3/8"?
After taking the back cover off of the laptop there is a pretty big slot marked WPAN with a blue cable ran to that spot held down by a black piece of vinyl. The 370 I got doesn't seem to fit the plug-in connection unless I'm missing something. Also I don't see what would hold the card down because it isn't long enough to reach what looks like 2 screw down posts at the top of the slot.
I've never installed a mini-card before or even seen what they should look like, can anyone verify I have the right card or whether I'm just not smart enough to figure out to install it, I won't be offended if the latter?
