It doesn't always work. I have two machines, one that has issues with a north bridge, which initially prevented shutdown and prohibits, suspend and hibernate. And another where the Bluetooth dies until reboot on an Intel wireless card. Another machine wouldn't upgrade due to a wireless card, that took about three days of troubleshooting. My Linux boxes glitch too. I rarely have stuff that just works.
