Acer Aspire 3100 Laptop Monitor will not turn on

Go into your display settings. It should show at least two different monitors. Your laptop monitor and the external one your plugged into. Click on the external one and click on the two check boxes. Click on extend the desktop into this monitor first. Then click on this is my main monitor. Reboot your computer and it should be on your external monitor.

Hi
Press and hold the power button on the laptop for over 5 seconds and it should turn off... or remove the battery and charger :)
When it turns back on, it will ask you some questions, just leave it alone and it will reboot by its self.

Hi.
It is best to test your monitor on another computer. If it does not work on another then the Monitor is definitely the source of the problem. If your monitor works on another then the problem could be your video card or that your resolution is beyond the capability of your monitor. To test this, when you restart the computer if you do not see the BIOS screen or even the windows logo screen then it is the video card, but if you do and this problem occurs when you are in windows then your screen resolution is the problem. You could also try using a different monitor on your computer to check those settings.

If it was just the hard drive, I would expect the video to come on and say something like "no boot device."
However, since you went through the steps here and see absolutely no video (even none on an external monitor), I would suspect a motherboard failure.
Be sure that when you hooked up an external monitor that you pushed the Fn key and the appropriate special function key (maybe F7) that switches between the laptop and external monitor. If you have done that (pushed the combination several times to switch displays), then you can be pretty certain your video card (if a separate card) may be bad.
I'm not really sure if this machine has a separate video card. The specs say it's a ATI Radeon Xpress 1100. This leads me to believe it may be a separate card.
If it's just the card that went bad, you can replace it. Otherwise, the motherboard will have to be replaced.
Good luck. You can do that, but if you're not confident, you best take the machine to a repair shop.

Have you tried hooking an external monitor to the system? If that works you may have accidently switched the screen to an outside monitor. Or you could have a bad connection. Try starting in safe mode and see if it works.

you need to toggle the screen on by use of a key on the keyboard... do you see one that resembles a monitor...

display card burned change it

rate me fix ya

You need to change MOTHERBOARD

1. Mainboard failed
2. Vga adapter failed

I wouldnt be suprised if the vga failed, my acer broke down on me 2 times, on the 3rd time it was too much and I sold the laptop.

Hi Mikey,

Bottom row of keys, you will see on marked Fn. It is a specific color. Hold that and look at the top row of Keys. You should see one with a laptop screen, and a monitor on it. Tap the key once.
Each time you tap it, while holding the Fn (Function) key, it changes your optons. Once it will set your display to Laptop only, again will set your display to Monitor only, and again will set your display options to both. Play with the key combonation, and you may have to reboot with each tap.
Good luck.
