i bought a used hp pavilion ze2000 laptop. I started dual monitoring with a gateway monitor and everything was working fine. then, after i restarted my computer, it made the gateway monitor the primary monitor and it won't recognize the laptop screen. the screen won't even turn on. i can still use the computer fine, as long as i have it connected to a monitor. if anyone knows what might be wrong, i'd really appreciate it.
Screen: ATI RADEON XPRESS 200M
