please help me fix these problems because i really like ubuntu 12.04 and i have replaced my windows 7 ultimate for this everytime i turn on my ideapad it hangs, but when i insert my usb device that i used for the installation and restart my ideapad, it works. How can i open my lenovo without my usb device? my keboard doesn't work. i pressed each key and none of it work. those are the first two problems, i haven't tried the microphone, speaker and webcam yet because I really hate that i can't even type a single letter. please do fix this problem.
