I've installed F17 32bit on my new laptop Lenovo Z580. Everything was ok, but after first restart system not booted. The screen was black but when i typed the letters was shown on screen. Ctrl-alt-del doesn't work and i must turnoff laptop. Later I red about problems with optimus technology. So i turned off GeForce card and use only integrated Intel video card. But problems remains. After turn on computer system is booted. But after reboot not. How can I find what is reason of this?
Can anybody help me?
Sorry, my english is very bad :-(
