I would recommend reseting the bios to see if it is the graphics card that has the problem, if after a reset it is still lblank then your graphics card may need replacing

Broken screen, external monitor via VGA won't


Press "Fn+F7" once, wait a few seconds, and press it again, to "cycle" through all the possibilities (LCD-only, VGA-only, both).

Try the monitor with some other computer (desktop or laptop) to see if the monitor works at all.

Restart your computer -- does the initial "splash" screen (showing CPU speed and RAM-test) show? Does the "Windows" screen (with the crawling worm) show on the external monitor?

Power on - blank (black) screen


Disconnect the monitor signal cable from PC and switch on your monitor. It should show some logo with Red, Green and Blue colors with a message similar to "No signal". If so, your monitor is working fine. Sometimes if the brightness and contrast is set to zero using controls present in the monitor, it will not show up anything. check wheather somebody set your monitor brightness and contrast to zero. If so incease them. As a last try connect to different PC and check before approaching a service center. I hope this will help you out. :)

How do I do about resetting the bios to see if my monitor issue is the graphics card that is causing the problem?


Hey Hi Mary,

Well if your system has an EXPANSION GRAPHIC CARD then in order to find out if the GRAPHIC CARD has gone bad u actually need to remove it from the system then hook up the monitor in the INTEGRATED VIDEO PORT. If the monitor works well and good then its the GRAPHIC CARD which has gone bad.

Because until the GRAPHIC CARD is installed in the system the system by default keep ignoring the INTEGRATED GRAPHIC CARD it will not even detect whether the system has an INTEGRATED GRAPHIC CARD or not..

Kindly Reply Back If You Need Any Help..

Monitor goes black, with ghost lines of white. unplug and replug sometimes works sometimes does'nt. it's almost like it's burn out, or blown. pounding on the top works great, it comes right back on. this...


Its more or less your monitor has gone bad.
To check the same , unplug the monitor from the computer , a slef test feature check would be displayed . Check if the monitor goes blank or shows ghost lines . If yes the monitor is bad. If you have got the system before 12 Dec 2005 its generaly covered under 3 yrs warranty.If purchased after that , it would have your system warranty
