    Hi,

    I want to know if anyone had reinstalled a Lenovo Thinkpad T400 to Windows 7. Were there driver issues after the reinstallation? It came on Vista preinstalled, I did a downgrade to Windows XP and that was the genesis of my problem with a lot of the drivers.

    Thanks as you respond.

    Well...I installed Win 7 Pro on a R400, which is a slightly heavier version of the T400 and I faced no problems. I then downloaded the ThinkVantage System Update and the Power Manager (but not the Access Connections utility). Most of the drivers were retrieved by Win 7, while System Update did the rest, including the BIOS update. But be cautioned that sometimes it is better to update the BIOS by yourself and not with System Update. Supposedly, it causes problems, but it did not in my case.

    Good Luck!

    Well, there are some bugs but overall its pretty pain free upgrade process. As the above poster mentioned install the system update and it should find most of the necessary drivers/software. I have been running Win 7 ever since its public release last Oct. and the only issue, I hope lenovo will fix eventually is the switchable graphics which has a problem when the system is put to sleep. (if you are running in IGP mode then both GPU become active when resumed, can be fixed by switching back & forth between the 2 GPU's after resuming from sleep). This wont be an issue if your system has the IGP only.

    Been running Windows 7 on my ThinkPad T400 for a while now and it’s flawless. As for the switchable graphics issues, I wouldn’t know. Had I known Lenovo crippled this functionality by only allowing manual switching—as opposed to automatic switching based on power state—I would probably not have bought it. That being said, since the switchable graphics are not that useful, I locked the graphics to the Intel card in the BIOS—and the machine performs flawlessly.

    My wife has a T400 and other than a resume issue on occasion it works near flawlessly. She loves it.

    She's been running Windows 7 for months.

    Other than the annoying switchable graphics issue after resuming from sleep that miner mentioned, I have no driver issues with my T500 in Win7 Pro x64 at all. I used System Update to get all my drivers, and it worked flawlessly.
