Hi! I'm still not able to use Optimus and so internal LCD. Can you give me a link of your modded verde driver? Thank you! -
What Verde driver did you use?

Hi! I also can't get optimus work (http://forum.techinferno.com/diy-e-gpu-projects/4182-thinkpad-t400-gtx-650-ti-2gb.html)

I have done a clean windows 7 64 installation on the new SSD drive, so i installed the intel driver (from intel installation) and so i installed the latest nvidia desktop driver. Restart and cheked the regkey....the AppInit_DLLs was empty, so i added the C:\Windows\system32\nvinitx.dll value myself. Restarting..and nothing. I can't see the option for the Optimus...

Ok, installed with modded driver but...nothing . The preferred graphic processor won't to show up. Thank you anyway for your help. Anyway i saved two Everest report for a comparison between booting with GPU already pluged and pllug it after BIOS as suggested from nando. Here you go (it's a truly mess LOL):

How can i be sure that the Intel was booted as primary? Where can i check?

Did anyone know if the GTX 650 Ti (GK106) have Optimus feature?

Ok, I did my tests. I followed your suggestion and boot up with the "hotplug after BIOS post to avoid BIOS detection" solution, but the situation is the same as boot with all aleady connected. So i follow your 2nd suggestion and i installed the last Intel GM45 unbranded driver. And boot again with "hotplug after BIOS post to avoid BIOS detection". But nothing again..the Nvidia Panel come up only if duplicate or extend or projector only mode. Also the "Preferred graphic processor" in the "Manage 3D setting" tab is missing. :too_sad:I also notice that, starting with the hotplug method i lost the audio.I want to inform you also that playing with the lastes Nvidia driver .inf i found that for the GTX 650 Ti the following keys are missing: [nv_miscBase_addreg__##] HKLM,"SoftwareNVIDIA CorporationGlobalCoprocManager",OptimusEnhancements,%REG_DWORD%,1 HKLM,"SoftwareNVIDIA CorporationGlobalCoprocManager",ShowContextMenu,%REG_DWORD%,1 (I followed this post:

Hi guys, i want to report my experience with this configuration. All was with the aim of best performance per watt per dollar per volume: PSU 12V 30A + 12V to 5V DC-DC converter (18€+3€) Zotac GTX 650Ti 2Gb (used for 100€) [one of the best performance per watt per dollar when i buy it ASUS GeForce GTX 650 Ti Direct Cu II 1 GB Review | techPowerUp] Lenovo Thinkpad T400 (only intel 4500MHD video, 8Gb ram, T9500 @ 2,55Ghz upgrade to T9900 (used for 45€) @ 3.06 Ghz undervolted @ 1.1V 35W TDP) (used for 250€) (very reliable and rugged notebook) PE4H 2.4a + hdmi cable + express adapter (used for 45€) Wired all up and: 1) plugin the express card adapter 2) power up the PSU and video card 3) power up the noebook Everythng go fine, windows 7 boot up. Card was recognized, so i installed the lastest nvidia desktop driver (320.49). All ok. External video work. Now there is something that i can not solve: 1) if i do not clone or extend the desktop on the eGPU i can't open the Nvidia control panel 2) can't find the "Preferred graphic processor" in the "Manage 3D setting" tab in the control panel (so i do not know if Optimus work) 3) can't figure out how to use internal LCD. Can someone land me a hand? Thank you guys EDIT: I finally get optimus working for my 650Ti card with 306.97 driver (luckily it is the first driver that support gtx650Ti!! and the last that support optimus for intel 4500MHD!!!!! :bananadoggywow:) with modified inf nvwi.inf - Komeil Bahmanpour Download Center , and the Microsoft Intel driver 8.15.10.2555: I'm now think to implement this setup using one of the other pcie slots of my thinkpad T400: - one internal (unknow if root port 1 or 5) - one which is used in the docking station (Thinkpad Advanced Dock) (unknow if root port 1 or 5) The other already used are: - wifi (root port 2) -express card (root port 4) [there is no root port 3 :confused:]
