I connected my Toshiba laptop to a LCD projector. I went to Control Panel - Device and Printers - Connect to Projector - External Screen Only. Nothing showed on the projector and now my laptop has a perpetual black screen. How can I fix my laptop? Thanks for your help.

Just hold down the function key (FN) press F5 to toggle between displays.

I've already tried that, and nothing. I've powered off, removed the battery, pressed the power button for 30 - 60 seconds. Turned it on and still nothing. What else can I do?

The GPU controller could have a major problem. Have you tried Safe Mode?

Go to start and type hwsetup. Click on the keyboard tab, select standard F1-f12 mode then try FN+F5 again. You can also try taking the battery out, with the battery out hold down the power button for about 30 seconds, reinsert the battery and boot.

Also try:
On the Start Menu go to All Programs/Toshiba/Utilities/
Click on “Restart Flash Cards” if it exists.
Click on “Settings for Flash Cards” if it exists. Make sure the “Disable all function keys” option is unchecked and click OK.
Then try FN+F5 again.

That could fix it.

I've tried Safe Mode by starting the computer and taping F8 several times. Can't see anything on the screen. Also, can't go to Start because the screen is black. Thanks for your ideas.
Any thing else I could do?

Plug in a usb external keyboard. Wait for about 10 until you think it booted into the OS and try the FN+F7 or FN+F8 or try any of the Function key combos from F3-F12 to toggle through display Also if you can get into the BIOS when the computer starts press F2. and reset to defaults.
