Lcd screen stuck in external screen mode


How to use the function (Fn) keys on the keyboard - ThinkPad T40, T40p, T41, T41p, T42, T42p, T43, T43p


Switching the display output location.
Switch between the computer display and an external monitor. If an external monitor is attached, the computer output is displayed in the following three patterns by turns:
  • External monitor (CRT display)
  • Computer display and external monitor (LCD + CRT display)
  • Computer display (LCD)
Notes:
  • For any operating system other than Windows 2000 or Windows XP, no additional procedure is needed. Just press Fn+F7.
  • This function is not supported if different desktop images are displayed on the computer display and the external monitor (the Extend desktop function).
  • This function does not work while a DVD movie or a video clip is playing.
To enable this function in Windows 2000 and Windows XP, the following procedure is needed:
  1. When you log on to Windows 2000 and Windows XP for the first time, press Fn + F7 and select a display-switching function in the Initial setup window. Since in Windows 2000 and Windows XP multiple users can log on to a single operating system by using different user IDs, each user needs to select the function in the initial setup window when logging on for the first time.
  2. If the Fn + F7 key combination have been assigned to a presentation scheme function, start Presentation Director, and change the settings.

Broken screen, external monitor via VGA won't


Press "Fn+F7" once, wait a few seconds, and press it again, to "cycle" through all the possibilities (LCD-only, VGA-only, both).

Try the monitor with some other computer (desktop or laptop) to see if the monitor works at all.

Restart your computer -- does the initial "splash" screen (showing CPU speed and RAM-test) show? Does the "Windows" screen (with the crawling worm) show on the external monitor?

I connected my laptop to my LCD TV using VGA cable. I changed the mode to VGA external monitor. Image/video appear perfectly fine during start up. but right after windows logged in for like 5 second the...


Easy way:
Press and hold Fn key, and then look at the F1-F10 keys.. Most likely it is F7, and has a picture like a computer screen.
So, press and hold Fn key, and then press F7 (or whatever key it is for your laptop). This will change your "presentation" settings, and thus switch back and forth from laptop screen, laptop screen + external screen (TV), just external screen (TV).
-------------

If this doesn't work as you expect, just try:

Instructions for Windows XP:

Open the Display Properties window by:
Start -> Run -> %windir%\system32\control.exe desk.cpl,@0,3
(this is the same window where you can change screen resolution).

There you will see two or more "screens", labeled: 1, 2, 3.

Click on "1", and you'll see:

[X] Use this device as the primary monitor
[X[ Extent Windows desktop onto this monitor

Click on "2", this is your TV.. Mark

[ ]
[X] Extent Windows desktop onto this monitor

Then change the resolution to 800x600.
Click Apply

=> now your TV should start showing you a picture.
You can move your mouse between the laptop screen and the TV screen.

If you want just the TV, you can make "2" to be your primary monitor, by clicking on [X] Use this device as the primary monitor.

Unable to reinstall windows xp


try it again with the bootable floppy disk... if you have the option use fdisk /mbr and then format the computer and reinstall using the cd you have. the fdisk /mbr command will get rid of any virus residing in your master boot record.

After booting process done. Screen goes blank and Keyboard not working only Mouse cursor is dispaly and working on the blank screen in My acer Laptop.


Try booting the system to Safe mode.

To boot to safe mode:

Restart the computer. As soon as the BIOS has finished loading, F8 key on your keyboard. When Windows Options menu appears, scroll to select the Safe mode menu item, and then press Enter.

Select "Last known good configuration" then press Enter.

If that doesn't work reboot again and keep tapping on F8 to Safe Mode and instead of selecting "last known good configuration" select "Repair Your Computer"

Or you can try this:
Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";}
  1. Place your Windows XP set up disk in your CD drive.
  2. Turn off your computer and change your BOOT order to boot from CDs first.
  3. Turn your computer back on.
  4. Press any key on your keyboard when it asks you to.
  5. Press enter when you see a blue screen, one of the options should say, "To setup Windows XP now, press ENTER.".
  6. Press enter to start the windows set up.
  7. Accept the Licence and Agreement and confirm that the setup is searching for current versions on XP.
  8. Press "R" when the set up has found your current version of XP.
  9. Notice that the Set up is deleting all your windows xp files and replacing them. (This will not cause loss of data)
