Nvidia GTX 660m disappeared

I recently bought y580 that came with the intel 3610qm and the gtx 660m.

 

The problems I immediatly experience for the first 2 days of use is the graphics card problem. The gtx 660m would disappear by itself when i left the computer on idle. I haven't done any other test besides that. I did play Devil May Cry 4 for long periods and did not have any problems. I ran Blender with cycles and did not have any problems.

 

So the only problem would be left the computer on idle which for some reason disconnects the Nvidia GTX gpu. Is this normal? The only way I can get the gpu back up and showing in my computer again was to restart; now if I have to do this every time, that would be very annoying.

 

So which is it? Is this a driver issue or a defective graphic card? Or is this just the so-called optimus tech? Cuz either way, it sucks cuz I can't use the nvidia card when it turns itself off and disappears from the computer until I restart.

 

I've tried using the default factory installed driver which was the 295 something and the latest 306.97 nvidia geforce drivers for the 600m series but still, whenever I leave my computer idle, it turns itself off.

 

Please inform.

Re: Nvidia GTX 660m disappeared

it is a power management issue, computer switches to HD4000 to save power when idle

Re: Nvidia GTX 660m disappeared

disappears?
you mean from the Device Manager list?

 

it's always supposed to be present in the device manager list.

 

to test, you can use GPU-Z and call the gtx gpu sensors in the sensors tab. If the card is there, gpu-z will detect it, and that means it's working

Re: Nvidia GTX 660m disappeared

Ok, this is what I noticed when my graphic card turns off when on long periods of idle (left on for hours), the device manager shows both the intel and generic VGA (which was suppose to be Nvidia when nvidia was turned on).

 

I tried uninstalling the lenovo power management to see if that fixed the problem.

 

I'm still wondering if this is normal as long as the so called descrete card show up in the device manager just turned off and changed to the useless generic VGA; what happen is, is that in order to get the Nvidia, back up, I have to manually restart the computer.

Re: Nvidia GTX 660m disappeared

Methods you described did not do anything to help fix the nvidia turn off problem.

 

I checked again, and the nvidia card actually is listed in the device manager after it is turned off due to the computer being left long periods of idleness for hours. The card is actually renamed in the device manager as something generic VGA and that is a useless card until I restart the computer then the Nvidia comes back on again.

 

I also tried uninstalling the lenovov energy management driver to see if that was the culprit. I will let all of you know if this solved the problem or not as I am not the only Y580 owner to experience this annoying problem.

Re: Nvidia GTX 660m disappeared

that is unusual.

your nvidia graphics driver is uninstalling itself, and that should not be happening.

this is a clean system, right?

I have read that corrupted OS can cause drivers to act this way. What you'll need to try is to restore factory image, and if that doesn't work, get a windows iso, format, and clean install windows

Re: Nvidia GTX 660m disappeared

Ok, I find out what the cause of my Nvidia GTX 660m 2gb graphic card to turn itself off on long periods of idle (like more than 8 hours or so).

 

The culprit is the  the Lenovo energy mangement program/driver that's causing the graphic card to turn itself off. After I uinstalled the energy management system, the graphic card now stays on. Smiley Very Happy

 

However, if you uinstall the energy management system, you will no longer have the following working:

1. onekey theather mode button doesn't work (next to mute button) but the onekey theater mode still works but you have to manually adjust it on screen and usually, the icon is located in the notification but if it's not there, then try finding it in the start menu.

 

2. fn+f5 wifi, fn+f4, and fn+prtsc, do not work. fn+pause, fn+scrLk, and fn+break are useless so I don't really care if they work or not because I don't use them but if you want to know, they don't do anything when I tried to pressing those.


3. Your onscreen indicator such as cap lock, number lock will not show up so you might need to check the LED on your laptop located at the bottom of the touchpad.

 

You will now only have two performance modes (at least for me) to choose from: balance and high performance.

 

I currently have the 306.97 driver installed for my Nvidia GTX 660m 2gb. Problems with thte driver will affect 3ds Max 2012-2013 and Autocad 2013.

 

Well, let me know if uninstalling Lenovo's energy management solved the same issues I had.
