I have a Lenovo W500, which has dual boot.

When I boot into Windows 2008 R2 and connect to an external screen or projector, the keyboard locks. Sometimes it is just a few of the keys, sometimes keys start different programs.

I do not have this problem if I boot with windows 7. I have run windows update, but it did not help.

I can only say the usual stuff. Windows Server is not a supported operating system. Its for...servers. If you need some functions, use VMWare. Why do you use it in the first place? –  Shiki Jun 10 '10 at 13:02
    
@Shiki, We use it to develop SharePoint applications, we would have less memory available if we used VMWare –  Shiraz Bhaiji Jun 10 '10 at 22:19
    
Hmm VMWare can assign about 16gb ram per guest and W500 supports 8gb memory as far as I know. | (Okay I know you want to use Win Server but sorry I don't know a way. Maybe you can try installing Lenovo System Update + the drivers from Lenovo, maybe they will install without a problem (the Windows 7 drivers that is.) –  Shiki Jun 11 '10 at 5:13

This is a longshot, but I wonder if you're having a problem with a stuck modifier key, somehow triggered by the display switch. When the keyboard 'locks', `press & release each of the modifier keys once (windows key and both sets of shift/ctrl/alt keys) to make sure none of your modifiers are stuck.

If one of the modifiers is stuck typing normal keystrokes will lead to unintended results. For example: typing 'w' with the control key stuck become 'CTRL-W' (close window) or 'enter' becomes 'ALT+ENTER' (open properties), etc.

Thanks, ended up fixing this by getting a new machine :) –  Shiraz Bhaiji May 12 '11 at 12:40
