Thank you for your advice! I downloaded the patch and installed it as stated. During the installation it said something like "this system does not require this patch", but I completed the instructions and rebooted. No luck....:-(
When I hit "Fn+F4" to put it to sleep, the screen goes black, the harddrive light flashes for a bit, there's a beep and it shutdown. When I touch the space bar, it completes a full reboot and asks if I want to boot in "Normal mode". Once in Windows, I get an error that Windows was not shut down properly. Any ideas?

That usually has something to do with a power management driver issue, which is fairly common when upgrading older laptops to Windows 7. Try installing the driver below from Lenovo.
