T61 problem activate Nvidia NVS 140M to Intel X3100 or visa versa

Hi
I have Lenovo T61 with all lastest updates of drivers, window xp, to bios.

My T61 cames from factory default with Intel X3100 graphic drivers. Following this forum, I installed new fresh windows xp with activated Nvidia Quadro NVS 140M by entering bios changed the display option from Internal to PCI-Express.

Everything is working fine now, but my machine uses alot of energy, it lasts about 1.5 - 2 hours maximum on wirless, CPU 800, tweaked all programes running at minimum.

Now I want to use again the Intel X3100 graphic card. I uninstall the driver of Nvidia in windows, restart, and change the display option from PCI-Express to Internal. But the next restart, my window recognizes only Nvidia card.

Please help me to figure out what happens to my T61. Can you swap easily from Nvidia to Intel by changing bios only or visa versa?

Thanks in advance.

P.s: My T61 with T7300 2.0 runs very hot. At 800, it runs about 47-48 degrees celcius, at full speed, it can get up to 58-60 degrees celcius. How about you? Do you have any specific methods to cool down your system?

 

The T61 has only one graphics card or the other, not both. The PCIe option is likely a docking station based solution much like the expansion station for Dell Latitudes, but those are only really good at driving an additional monitor or something.

 

Thanks Greg. That's unbelievable. As I state before, my T61 cames with Intel X3100 driver in default fatory setup. I ran it several days with Intel UI option. After that, I feel not good to use Intel graphic card, and I reinstall windows and having Nvidia Quadro driver up to now.
Besides, I bought my T61 from my university. There's alot of T61 with Intel graphic likes me.
That means there's some hidden option to active Nvidia or Intel graphic card, isn't it?

 

There is no hidden option. The nVidia driver installed as you said, but it did not find any hardware to use it with. Either the 'standard VGA driver' or the driver for the X3100 was still working, or even your desktop display would have been stuttering.

The X3100 and NVS versions of the T61 use slightly different motherboards and parts, and I can guarantee you that you only have the X3100.

 

Its kind of like buying a v6 charger and using a HEMI engine cover....

you can easily install software/drivers but if you do not have the hardware it will not change a thing.

Uninstall the driver and reinstall the X3100 graphics, you'll be wasting your time trying to convert your thinkpad to nvidia graphics without swapping the board.

 

you have only one video card. Drivers you can install all you want, but those would just not work, or mess up other similar drivers.

 

Thanks you guys.
But all of you misundertood my message.
My T61 cames with windows Xp sp2, under device manager, I saw the display is Intel X3100. I use my laptop for several days without problems when I played or changed the option display.
After reading some infos here and others, I decided to refresh my windows, and under my device manager it only have Nvidia Quadro hardware.
As you stated, T61 only have 1 graphic. I accept it now.
But you guys think again if I doubt about this:
- On desktop, you can choose onboard Intel card or PCI-Express card via bios. How about laptop, maybe it has one graphic card only.
- Secondly, if default factory installed with XP SP2, there's lot questions how there's Intel hardware card installed under Device Manager. It's difficult to install different card drivers for 1 card, because XPSP2 has ID hardware. Sometimes you can use or hack softwares to think this hardware as other, but it should be in the same category, likes Intel for Intel, Nvidia for Nvida. you cannot choose Nvidia ID over ATI ID.
- Thirdly, I don't tweak my T61, but the UI (driver interface) can choose any option in there. Normally, software will dectect right ID hardware, why it can give you info clearly it's a Intel GMA X3100. Is it impossible, isn't?
Thanks for your input.

 

You cannot switch Video card displays on a laptop. Are you tell us that under device manager, your T61 originally showed Intel X3100, but then you reinstalled XP SP2 and now it shows Nvidia Quadro?

 

If it really happened then i need to do that to get a 570

 

LOL, but it's true

 

That's very odd, I've never heard of such a thing. It may have been some driver conflictions. What did your originally order your system with?

 

Order from my university in Quebec, Canada. Over 20 years, first time I see it. But in my logic, maybe due to econo, companies like to combine 2 in 1, or 3 in 1. It maybe activate over the software or the pin. Like Seagate 320 Gb part inside is 400 Gb or 500 Gb, it is controlled by it bios, you can tell me many things of this kind.

 

Its pretty easy to determine if you have the Quadro or X3100, just load up 3DMark and see what you score. The performance difference between the 2 is huge. My 140 gives about 1600 on 3DMark06, notebookcheck reports the x3100 at 463. So you should be able to easily determine which one you are using - also just running the Display control panel should tell you right click desktop -> Display -> Settings

 

If he has both and it's changeable in BIOS then that test wouldn't work. I say just open the laptop and look yourself. It's not hard. Just take the screws out from the bottoms, under they keyboard. Take off the fan and it should have the video card there if it's not integrated. It's a good opportunity to put nice thermal paste too!

Also which chipset goes your laptop have?

 

I don't see why it wouldn't work, you select the Quadro in BIOS, and then run the benchmark, if you actually have the Quadro your results will be significantly different than when you have the X3100 installed.
