Motherboard or what?

I have tried hooking up to a duel monitor, cause I have a laptop, and there still is nothing showing on the screen. I don't know if the video card has gone bad or the motherboard. Nothing happens on the laptop but the lights coming on. Please help?

The laptop is most likely unable to start up. In most cases its a hardware issue, should take the laptop to a local professional for a check or if your in warranty contact toshiba.

Possible reasons could be bad memory, failed mainboard, failed video adapter, loose contact between display and mainboard - but since you have already tried a external monitor and noting, then its not a cable problem.

You can try reseating the memory in the bottom of the laptop, it will be covered with 2 screws.

Remove them, and take out the ram from the computer, make sure they are clean, do not use water, or clean them, you can use the eraser end of a pencil to clean the contacts on the memory modules.

Place them back in and make sure they are in the right away, only handle them from the sides.

If the problem still remains, unplug and remove battery again, (might aswell keep the battery removed untill the issue is solved.)

Remove both ram modules from the laptop.

Start up the laptop with no ram at all, it may beep or complain, or it may do noting, unplug after 1 minute.

Plug in the other memory card, plug the machine to power, try starting up, if it works, turn it off and place in the other aswell, turn on and see if the machine works, if it does, problem solved. If it does not work.

Remove both ram modules, try the other memory on both slots and try starting up each time, remember to unplug power every time.

If the problem remains then do the same with the other memory module try it on both slots.

This will require repair in any case take it to a local professional.

Whether it is the video card or the motherboard as a whole doesn't matter at this point. You have done all you can with what you have. No video is usually a fried graphics card and on laptops, for the most part they are integrated and non-serviceable. I would go with a new motherboard.

Below is the link for your laptops tear down and service manual. Good luck.

Acer Aspire 4930 not starting.... only black screen


Hook a spare monitor to the video output, usually on the back, if picture okay! the LCD screen on the laptop has a bad inverter board or the backlight behind the screen has failed. But if both show the same symptom the Video Graphics Card is bad usually built into the motherboard.

My hp pavillion tx 2000 laptop is not working.............. when i turn it on, all the relevant lights comes on but nothing appears on the screen. i only get a blank screen.................. what could...


If you hear it start up and the lights come on, try hooking up an external monitor. When you do, be sure to push the Fn key plus whatever special function key shows 2 monitors on it so the output will be directed to the external monitor.
Sounds like the LCD screen might not be working.

My computer powers up but nothing appears on the screen. All lights indicate thaty the computer is on but screen remains black. What can I do?


Hook a spare monitor to the video output on the back of the laptop, If okay! the LCD display on the computer is the issue, cause, the inverter board is bad "most likely" that powers the back light, the less likely is the back light behind the screen. But if both screens show the same problem it is the video graphics card that is part of the motherboard. I suggest a computer tech.

We have the monitor hooked to a docking station for a laptop. I can not view the screen on the Viewsonic, but does display on laptop. I have been able to do an extende monitor view, but not the main view....


when you connect external monitor to a laptop u get two options in the monitor section of graphic properties tab

1.) extended
2.) clone

it is clear from ur post that u are using extended view

try using clone mode then both laptop screen and external monitor will show the main screen


other method is to disable the laptop screen and just allow external monitor to work, in this case laptop screen shows nothing but external monitor shows main screen
