    I have the same problem (gateway ml3108b laptop). I connected external monitor and the screen is also blank. I tried switching the output with Fn+F4, but no response.

    I have the same problem.  No sounds either except for the fan.  I've tried turning it on and off with the power button and using an external monitor all to no avail.

This is a GPU problem with this breed of laptop. The best way to fix is to treat it like an Xbox360 belive it or not. You have to overheat it at the GPU end (back of fan/heatsink) then press down firm but not hard over the back end of the fan. This should (worked for me) result in the BGA conatcts making a connection back to the soler pads they were meant to be attached to the motherboard.

If you are a bit more savvy with hardware i would recommend doing a reflow with a heatgun, i have not had to do one "YET" myself but if you feel you have to then go for it. The same rules basicallly apply to a lappy as they do an XBox360.

Doing a search for XBox360 Heatgun in good ol google may bring you a few pointers otherwise. Same rules basically apply to a lappy.

I deliberetly caused mine to overheat then bent the board ever so slighy whilst still hot (NOT RECOMMENDED) so the GPU made contact with the Motherboard again and it has been working fine for 5 days now, don't know when i will have to perform a reflow though.

Best of luck to you and hope this helps.

1. check if your video image is being directed to the an external monitor and toggle it back to your lcd screen using fn+(function key) (it could also be shif+ function key)
*note: the function key should show a pic of a monitor, look at the keyboard and also look at your laptops's documentation.
2.if above solution does not return the picture to your laptop lcd screen plug an external monitor and redirect the image with the function key as directed above, if you do get an image on the xternal monitor but nothing on your lcd screen your lcd screen is finished
3. if you don't get any image on neither screen this could mean your video adapter on your laptop's motherboard is dead, in which case you only resource is to access your computer via remote desktop connection.

hope that gives you an idea of what to try in order to find out where the problem lies.

The backlight inverter board may be bad, or worst case will be bad lamp. You should look to see if the cable comes off the inverter board first. You may learn maore here:

Gateway laptop ml3108b no screen coming on

this is a common fault with this laptop, the only way to repair this is to strip the laptop, remove the mother board, heatsink and fan under the heatsink you will see the nvidia chip this needs to be heated to 480C for about 5 mins only heat the nvidea chip nothing else! paste chips and replace heatsink fan etc laptop should now be fixed, remember to clean fan whilst it is out as a clogged fan probably caused the fault in the first place

Gateway ml3108b laptop wont start up

shine a flashlight on the screen. if you see a faint image, its the backlight thats the problem and you will need to get a new one to fix that. But if you dont see a faint image you will need to hook it up to an external monitor( an monitor that is not made into the laptop) , and if you see an image on the monitor you will have to clear the CMOS.
and to do that you will need to take out the battery, the plug, and hold down the ON button for about 30-60 seconds. Well thats how you clear it on most laptops. But if it does'nt work on the external monitor you probally have a bad video chip and need to replace your old one.

Gateway laptop powers up but screen does not come up.

See if you can attach an external monitor to your laptop.If you can and you can see your display on the monitor the it is a faulty laptop screen .If you see nothing on the x monitor then the graphic card/chip is fried.
