Unpluged VGA cable now no display.

Hi,

Does external display work fine? If you have not checked, connect an external display like desktop monitor or a LED TV which has VGA connector to your laptop's vga port. You may have to use some fn keys combination to switch from laptop display to external. If external display works fine then check the display cable connecting laptop motherboard to laptop display. And also check laptop LCD/LED screen. You may have to try another with another screen in such scenario.

you need a dvi to vga adapter not a dvi to vga plug and you must also go into your graphics card setup catalyst control center if its ATI Nvidia Display manager for Nvidia if you boot the computer with it pluged in and you can see the boot screen on bolth displays then its an os thing just right click and select the display manager the activate all display's through the managers

1. Check out display and its cables and make sure that its working fine.
2. Ensure that RAM is fine
3. If it is the faulty on-board VGA, then u may consider adding additional AGP card to get display

your on the right track with the video card could need reseated, make sure is set to default in bios, when you get into windows with it pluged in to the onboard vga can u look in device manager to see if its showing up in there and isnt malfunctioning, then again it could just be bad electronics go out all the time

Try leaving it off and unplugged for a while then hold power button while pluging back in to reset. Most brands of tv's flash to display trouble code.

Does your desktop/PC display show anything before the monitor goes into power save mode? If nothing comes up, its possible that you have a loose VGA connection or that your video card/motherboard are defective in some ways. Try using a different monitor.

If the other monitor works fine with your computer, try changing/lowering the screen resolution. If in XP right-click on the desktop and go to Properties, and select the tab for display settings and adjust the resolution. If in Vista/Win7, right-click the desktop and select Screen Resolution/Display Settings and adjust it there. Then check and see if your LG monitor works on it.

If the other monitor also doesn't show any display, most likely the problem is either with your video cable or your PCs video card/motherboard, not the monitor.

Hope that helps. Good luck

If it displays nothing at all through the boot process it's either the cable or the VGA card. It may be that the computer has gone into hibernate as it was left on overnight. Try pressing and holding the powerr button.

Looks like you've got a busted nic or ethernet card.
Your best option is to contact your manufacturer for support.

check all power cable. check vga cable,

sounds like the power supply---open and check the power supply for bulged caps--replace those
