I have a lg monitor hooked up to my hp pavalion. After being on for some time the monitor will black out and i have to reboot. how can i fix this problem?

Your screen resolution or refresh rate is set out of limits for the monitor. Check your monitor documentation to determine the correct resolution and refresh rates for the monitor. Then reboot the PC, go into SAFE mode, then re-adjust the display resolution there. Once you reboot after that, the monitor should be fine.

first ,try to reset the BIOS ..if you still have problem after that ,you must reinstall windows

The new hp pavalion dv8000 battery is fit for your laptop!

Detach it from the desktop monitor and try. There might be a key on your laptop which will enable u to use both displays.

Which power supply went bad? The 250watt or the 480watt? If a power-supply goes bad (dies), it generally takes some (if not all) hardware with it.

If the computer is attached properly and you get the flashing lights it is due to switch mode power supply being faulty, too expensive to fix I think you will find, never seems to be anything like just a fuse I'm afraid, modern worlds tells you its time for you next monitor..... do try to ensure it aint the pc by hooking laptop or something else to this unit, or hooking another monitor to your pc to be sure but I find power supply failure is normally how monitors leave this world...

Just plug another monitor to it. Generally all laptops have in the back, a connector for an extra monitor.

I solved the problem myself by disconnecting the monitor from the computer and then I unplugged the computer. I restarted the computer in position fail safe (F8) and tried to change the monitors resolution back to origin, failed to do so and rebooted instead. When Windows loaded up the problem was gone! Yipeyiiiii!

Hey there Celius,

Chances are the 'Refresh Rate' somehow got set too high for the monitor. On flatscreens , the result is a black screen.

If you have an old monitor (crt type) hook that up temporarily and reboot.

• Right Click the Desktop
• Click Properties
• Click Settings
• Click Advanced
• Click Monitor
• Lower the refresh rate or set at optimal
• Check the box 'Hide refresh rates this monitor can't display'

Shutdown, Switch back monitors and try it now.

Good luck
Mike

Try reseating the Graphics card first..It may be loose. Or try it in a different slot.
