Re: Laptop computer connected to projector.
When the projector displays the background image and the lcd displays the desktop as normal you can drag the open windows to the left or right and display them on the projector. it sounds like this laptop has an internal video card. If you right click on the desktop it might give you options to configure the display settings for the video card. Not sure how you will get to it if it does not show up on the right click menu. Probably through the start menu or in the control panel there should be somewhere to change the settings for the video card. This will no be under the display settings though.
But once you find your dual display options you will be able to change it to make both displays the same

First make sure the output to screen is selected. Hold the Fn key and then press the F8 key. Hit this combination three times, ur until the display comes up. If it does. Done. THen grab a flashlight and shine it on the screen at an angle. Do you see an image? If so, its the backlight and the screen (possibly backlight only) need replacing. If not, borrow a VGA adapter and plug into the VGA port. Press Fn+F8 again three times. If it comes up on the display, then the issue is the laptop display, and you have found an inexpensive workaround. You can continue this way or replace the screen. Good luck.
Did you press and hold the FN function key plus the key that toggles the
display? In your case it might be the FN+F8 if F8 is the key that
toggles the display.
a flashlight on the dark screen to see if you barely see the icons on the
desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can be
any kind of monitor even the old big fat crt monitors as long as it has a vga
cable to connect to your computer's vga port. If the video shows on the
external monitor that proves your video card is ok, ,but your lcd screen is
bad. The video will show on most systems when you reboot without you having to
do anything. Some systems will require you to hit the FN (Function key) + F1
thru F12. Hold down the FN key then hit the correct key for displaying on
the monitor (F1 thru F12). The correct key will normally have CRT/LCD on
it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works,
then your screen is bad. If you see no icons by shinning the flash light
and nothing shows on the external monitor, then most likely your video card is
If your video card is bad you will not see anything on the laptop's lcd screen or the external monitor.
There are a couple of ways to turn off the wireless. 1) Look for a wireless switch on either side of your laptop or at the front of your laptop. 2) Normally the FN (Function Key) + (F1 thru F8) will toggle the wireless between on and off. To find the correct F1 thru F8 key to hit look for the )))) symbol which denotes wireless. Press and hold the FN key then hit the Function key that corresponds to wireless. Watch your desktop screen because most will display Wireless On or Wireless Off as you hit the keys. If not one sure way to know it is off is look at the computer at the bottom right of the screen near the time, it should go from being a solid green to a computer with a red X on it.
I see. Try to restore your system to a day the last time your toggle is working. If that did not work try to reinstall your drivers. specifically for your video card and the utility for your keyboard shortcuts.
Your Back light has most likely gone out.. There is a possibility that your resolution may be to high or that you have it set to output on an external display... If its your res. you should be able to hit F8 at startup to enter safe mode... If it is the external display you need to hit FN + the key that has a little blue or yellow monitor (its a different key on each laptop)
Ok.I got your point.Actually you're in extended mode.
Once you connect you can have 2 types of output to your projector.
1.Clone mode--> make everthing look the same
2.Extended mode--> have another new space for you to use.
** in extended mode you'll have a background of your desktop.you can drag any running program to that space.
How to setup clone and extended mode
1.Click start-->Settings-->Conteol Panel-->Display
2.Under Display Properties window click the last tab name settings
3.Under display select you 2nd monitor
3.Below Screen Resolution you should be able to see a checkbox "extended my windows destop on to this monitor"
please check this box for extended mode or uncheck it incase you won't to use clone mode.
u can try to take off the hdd, and at the same time, pls clean the memory slot in your laptop with a brush & some liquid solvent..
After that, try booting it without any HDD.
If u did not see any error messages, try take out the CMOS backup battery and neasure its voltage or get it replaced.
