I just noticed recently that when I tried to switch from from the Intel Graphics to the Nvidia card, the light didn't come on. Also I don't know if its related, but there is a weird slowness overall with the computer. Everything seems clean and ok. However I thought it be odd the the switch isn't working any longer and I can't access the Nvidia options either because it isn't connected according to the device manager.
I can't find any related issue so I decided to post. Any thoughts or recommendations?
Thank you for your help.

I would get it to service if you still have warranty and don't want to possibly void it. Does the silver switch button jump back to its place when you press it? Or does it feel like it hasn't got a spring to push it back?

Could be both!
Are you running on Win 7 32 or 64 bit??
Any antivirus software installed?
Looks like the driver is down or incompatible, i think you should disable and reinstall it updated.
Before that, hit the One Key Recovery Button, in order to return to initial back up (back up your data first).
Then focus on the drivers.
Let me now the status after the OKR.

I did notice in the Programs list there are two NVIDIA applications listed.
- NVIDIA 3D Vision Controller Driver 266.34
- NVIDIA Graphics Driver 267.43
Would this create a conflict with the driver and prevent it from turning on or do these work in conjunction with each other?

Tonight I made some attempts to remedy this issue using some of the recommendations.
First before I dive in with what I did. Something bizarre happened.
Windows did a general auto update.
"Update for Windows 7 for x64-based Systems (KB2679255)"
After the obligitory restart that is required, I noticed the light that indicates that the Graphics card is turn on, was lit up.
I am completely unsure why the light decided now to come on. I tried the switch but it still has no effect on the card or the indicator light.
I then begin the following. All to no avail and in this order:
- Downloaded both the MS fix and NVidia driver linked previously.
- Ran the MS Fix tool.
- Results indicated there was an error detected with the card. But no further info or fix.
- Uninstalled the two NVidia Drivers that were installed. (restart required)
- It found and installed a generic vga driver on reboot. I'm assuming to fill the nvidia card as it had no drivers connected to it.
- Installed Newly downloaded NVidia driver. (Restart required)
- No changed so I uninstalled the NVidia 555M device from the device manager. (Reboot Required)
- It found NVidia 555M and Installed with no error
- When viewing device manager it notes there isn a problem.
- I located drivers in the Lenovo backup drive and did clean install.
- Learned that the two drivers I previously posted were what were installed as a result of the backup driver installation.
However I'm back to square one with no change, other than the indicator light being on instead of off.
I'm not ready to attempt the OKR yet. I need to do some backup before I go that route.
If this helps anyone in regards to analysis, any more ideas are helpful and welcome. If I come across anything else in my attempt to fix I'll post my procedure.

After doing a little more research. I was able to locate an application in Windows called Reliability Monitor.
Its shows me a diagram of when there were critical alerts.
And I found some info when this issue may have started.
