I have the same issue... and while I haven't troubleshooted for these problems I have 2 theories.
1) I installed Microsoft 2010 which is the culprit.
2) I used the "Microsoft Windows Activator" tool which messed up my Lenovo bios settings.
It may be niether of these, but since this seems to be a common problem I thought I'd put some theories out there for people to test.
