Question about Acer Aspire 3000 Notebook

Pressed FN key simultaneously with F5 Key and screen black

I have a laptop computer that was put together by TDN.  The model number is CY 25.  Software is Windows XP.  I simultaneously pressed the FN key and the F5 key.  The F5 key also has an icon on it that looks like a rectangle inside parentheses.  Also, the FN key is a separate key in blue letters and the icon is also blue.  When I pressed the FN and F5 key at the same time, the laptop screen went black.  Everything else seems okay.  I tried to reboot, and the screen is still black?  Can anyone help me?

Monitor is dark. how to fix?


Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.

I have a sharp PC-GP10 CM laptop but the screen has gone black after my daughter pressed a button. I dont know what she did. I have rebooted and the laptop comes on but the screen is still black. Any...


Look for the Fn Button bottom left of the keyboard. Hold this button down then press F5. You should see the screen flash up. Have an external monitor connected to the vga output on the back of the sharp while you try this. The Fn Key and F5 combination is used to swith modes between laptop and external monitor, Dual view etc. You should see some activity when you do this. Hope this helps you out. Ps... Using the Fn key with F6 and F7 will Alter the brightness of the screen on your laptop.

The screen on our Dell Inspiron 1545 is darker than normal. It looks like it does when it is running on just the battery. How do we lighten it back up?


Actually it's the F5 key which also has a symbol of the sun on it and arrow pointing upward. Press the blue Fn key located at the bottom row, 2nd from the left and the F5 key together to increase brightness or the F4 key to decrease the brightness (it has an arrow pointing downward). Easy, eh?

Screen not working


It could be the 'back light' is burned out.
Or
Press Fn and F5 simultaneously to make sure the display
priority is not set for the built-in screen.
Or
Press the 'brightness up' key a few times.

Display problems
Here are some typical display problems and their solutions:
The screen is blank.
Display Auto Off may have gone into effect. Press any key to
activate the screen.
You may have activated the instant password feature by pressing
Fn and F1 simultaneously. If you have registered a password, press
any key, type the password and press Enter. If no password is
registered, press any key. The screen reactivates and allows you to
continue working.
If you are using the built-in screen, make sure the display priority is
not set for an external monitor. To do this, press Fn and F5
simultaneously (once). If this does not correct the problem, press Fn
and F5 simultaneously again to return the display priority to its
previous setting.
HINT: Holding the Fn key and pressing the F5 key several times will
advance you through the display options.
If you are using an external monitor:
❖ Check that the monitor is turned on.
❖ Check that the monitor’s power cord/cable is firmly plugged in.
-- Try adjusting the contrast and brightness controls on the
external monitor

Have you tried cycling all the way through the options with the F4? Most laptops toggle in a manner similar to: 1) Laptop only, 2) External display only, 3) Both displays, 4) Back to Laptop only (cycle repeats).

Getting the lenovo m500 dlp projector to work


Solved ....when it projects it says to push Fn and F7 simultaneously for Lenovo laptops. The symbol for the F7 on Lenovo is the computer screen and keyboard plus a screen with a line attaching. On the Toshiba it is the F5 key. Pressing the Fn and F5 keys on the Toshiba simultaneously gives 5 box choices, the middle is CRT and the correct one to transfer from computer screen to projector.

Swithcing from laptop screen to lcd monitor


Hi
Connect the monitor, flat panel, or projector to the laptop's 15-pin video connection on the back of the computer as shown to the right. Once connected, your laptop may automatically switch to the new external display or you may be required to press a sequence of keys in order to switch from the laptop to the external display. video.gif For example, often either Fn + F3, Fn + F5, Fn + F8, or Fn + F9 is pressed to switch between alternate displays. So if your laptop was Fn + F3, pressing and holding both Fn and F3 at the same time would switch between displays. Often, the alternate key pressed in conjunction with the Fn key will be labeled as CRT/LCD and/or have a picture of a monitor on the key or close to the key. Unfortunately, the keys pressed to switch displays is dependent on the model and manufacturer of the laptop. If none of the above key sequences work, consult your laptop documentation or consult your laptop manufacturer.
Some laptops also have the ability to have the display on both the laptop and external display and/or one or the other at a single time. Laptops with this ability can switch between these modes by continuing to press the same function keys until in the mode the user wants.

1. Check Power ( this includes the power supply )
2. Check Battery
3. Check to see that the DC power jack is not loose or broken.
4. Most notebook/laptops have a function key FN when the FN key is pressed you will be able to press the F keys , one of them will have a little monitor drawing on it.

if you press them both FN+F-Key ..... which could be F5 in this case , it will cause the computer to switch to either the VGA output , or the notebook/laptops screen. sometimes they get pressed by mistake and the person thinks they have a broken machine when in reality they do not.

Toshiba Satellite P200 doesn't boot


Try pressing FN/F5 keys simultaneously, or the key that toggles internal/external Display. Look for the double screen Icons on the keys.

Tap the Pause Key.

Restart and press and hold F8 key when Toshiba logo appears. When the boot Menu appears, select Last Known Good Configuration.

If all else fails ther should be a reset button on the side of the LT. Consult owners Manual for location
