... if no good unplug the mains adapter and remove the battery then reinsert it and hookup the mains again and just try turning the laptop "on"
... if still no good restart the laptop tapping the <Esc> key and enter your bios and look for "reset to default" or similar activate that setting.... save settings on exit of bios.... restart the laptop
... see what happens... if nothing enter the bios again and alter the booting sequence to cdrom first ....save setting on exit!
... post back here what you see on the screen even if its just a flashing cursor
... before you try booting up with the cd/dvd, (yes just place it in the tray and turn it on ... maybe)
