I'm using Windows 7 and some time ago my video card broke down. I can use the computer as I did, except I can't watch movies or play games, but that's okay with me. I'm not interested in putting any more money into it.

The only thing that bothers me is that now (with the video card disabled) I can't put my machine into sleep mode. Is there a way to go into sleep mode without a video card in Windows? Is it possible on Ubuntu (I might switch if that's the case)? Why is it required in the first place?

Technically a video card is not required at all. However is is quite possible that windows makes a few assumptions which fail when the device is disabled. Can you boot the computer without the card (not just disabled, with the card removed) and see if you can put it in sleep mode? –  Hennes Jan 12 '13 at 9:24
    
@Hennes The card is onboard, so no. –  Amir Rachum Jan 12 '13 at 9:31
    
How do you know the card broke down? Also, how exactly are you using your computer when the on-board video is disabled? Finally, some details about your computer (desktop/laptop, brand, motherboard, CPU, etc.) would be helpful. –  Indrek Jan 12 '13 at 9:34
    
@Indrek see this question I asked: superuser.com/questions/398532/… –  Amir Rachum Jan 12 '13 at 9:35

So when you say you disabled the video card, you actually mean you uninstalled the Intel/Lenovo drivers and are now running with Windows' default drivers (low resolution, no hardware acceleration etc.)? What exactly happens when you try to put the laptop to sleep? Try checking the Event Viewer. Also go to System (Win+Pause) -> Performance Information and Tools (lower left corner) -> Advanced Tools (left side), and see if there are any warnings there about programs or drivers interfering with sleep mode. –  Indrek Jan 12 '13 at 9:43

You can force hibernation from the keyboard, sleep mode ought to be possible as well.

Press Win+R, type in shutdown -h -f and press Enter. ( requires hibernation enabled and any Windows Client... perhaps not server OS

Try this command line or batch file:

%windir%\system32\rundll32.exe PowrProf.dll, SetSuspendState 0,1,0

I get "The request is not supported.(50)". –  Amir Rachum Jan 12 '13 at 9:55
    
spaces between switches ?? > shutdown -h -f also You must enable hibernation in order to use the -h option. –  Tony Stewart Jan 12 '13 at 10:29
