Acer Aspire 5100 monitor will not stay on

I solve this using Fn + F6, using a 5536 model. Just press Fn + F6, keep holding it and hit the power button, wait for about 5 or 7 seconds, release the Fn and F6 keys. thank you so much guys!

have you got the screen output on 2nd monitor only ?
hold down windows key it is right next to FN key and press P
also you may have changed the settings to make the second screen the defeult screen . (not sure how to change this just remember seeing it as an option in settings)

The Hotkeys are;

1) Fn (Function Key) + F1 = Hotkey Help; Displays help on Hotkeys

To go on anyway;


2) Fn + F2 = launches Acer eSettings Management in Acer Empowering Technology.

3) Fn + F3 = Launches Acer ePower Management in Acer Empowering Technology.

4) Fn + F4 = Puts the computer in Sleep Mode

5) Fn + F5 = Toggle the laptop from it's monitor to an external monitor, or use both.

6) Fn + F6 = Screen Blank > Turns the Display Backlight off to save power. Press any key to return.

7) Fn + F7 = Touchpad toggle > Turns the internal Touchpad on and off.

8) Fn + F8 = Speaker toggle> Turns the speakers on and off

9) Fn + Right Hand Triangle > Brightens the LCD screen

10) Fn + Left Hand Triangle > Decreases the LCD screen brightness

Go down to the second Aspire heading.
The one that starts with Aspire 1200.
Drop down to line 6, then go across to the right, and click on 5515.

This is a PDF file. The computer you are on now has Adobe Reader on it, which uses PDF files.
I would suggest upgrading to Adobe Reader 9 (9.3.4.) though, if this isn't the version on the computer.

After you click you may not see anything happening for up to 30 seconds.
The file is downloading in the background.
Usually it takes a few seconds to see the first page, and additional time to fully download.
Suggest you let the file fully download before looking through it.

This is a SERVICE MANUAL, not a User Manual. Much more detailed, including disassembly procedures.

Hello rcaste39,

Have you tried holding the [Fn] key at lower left of the keyboard and pressing the [F6] key in the top row at the same time? The [Fn] and [F6] keys combination toggles the screen on and off.

Have a great day,

it would be the blue lettered fn and f6 keys, hold fn key-then hit the f6 key to toggle display. otherwise try and reset the notebook- take out battery and unplug the unit. then push and hold the power button for 60 seconds. then put the battery and plug it back in, and try and see if that works. this has worked on my acer 5100 several times! the screen could have a problem also. this is what i worry about every time this happens 2 me. good luck! if i can help more reply.

open cbinet of crt,
then internally check circuit connection.
or check for external lead connect very well or not ,one of power,and data cable.

It sounds like your trying to use a full size monitor with your laptop. If that's the case you have to send the video to the cabled monitor by pressing the "fn" (function key) and then pressing the corresponding key that refers to a secondary video device (i.e. projector, monitor, etc.). Typically you press "fn" and f4 (should have monitor looking picture next to it), Some laptops are different, so look at your function (F1 - F12) keys to see which one is correct.

FN + F6 Turns the display screen
backlight off to save power.
Press any key to return
Try

Change the settings from the display settings panel. (Right click on the desktop and go to display settings)
You should see 2 monitors graphically represented there. 
You can make the monitor that is greyed out active by right clicking on the monitor, and selecting active.

if you dont have signal on your laptop screen, could be:
Broken LCD, Bad inverter, or bad graphics card.
