Sounds like you hit the Fn and another combination and dimmed the brightness down to black or turned off the light with another Fn combo. Reversing by pressing Fn and one of the keys that looks like a light should do the trick to get it back.

External monitor only works if I start windows vista in safe mode


First after you boot it up normally (not Safe Mode) can you move the mouse far to the left or to the right do you see the mouse. If you do see the mouse pointer you are running dual monitor mode and the laptop screen is set as the primary monitor. You have to run it in Save Mode and set the external monitor as the primary monitor. Hit the Start button then select Help+Support and in the search box enter "dual monitors". Read how to set up the primary monitor.

Second maybe you need to activate the external monitor. When laptops boot normally (not Safe Mode again) with a external monitor connected you have to hit the Fn (function) key (probably blue near Alt key) and some other number key (it probably has a blue monitor symbol on it) I'm not sure which one. This key sequence is a toggle sequence. In other words when you boot a laptop it goes directly to the laptop screen then the first time you do a Fn + number key combination it will turn on the external monitor and turn off the laptop screen the next time you push Fn+number key it will turn on both monitors (external and laptop screen) the third time it will turn on only the laptop screen and so forth.

Dell mouse not responding; diagnostics results says test passed. mouse works on other PC


Hello,
There is a very good chance it's one of two problems. First, while theoretically you can connect tons of USB products, sometimes USB ports can be kind of hinky... Try unplugging something else USB based and plugging in the mouse or try several different ports. Also be sure it's not plugged into a USB hub and is going directly into your computer. If this works play with the arrangement of your USB devices until you find a configuration that works, maybe you'll have to switch out a printer or external drive while using your USB mouse...
If this doesn't provide a solution the next thing to do is to uninstall the pointer device driver in device manager and allow it to re-install.
If you don't have an alternate mouse to complete the task, here is the keyboard shortcuts for Windows although depending on your version of Windows it may be slightly different.
-First hold the windows key and hit the r key (win+r)
this will bring up the run menu
-Next type mmc this will bring up a management console
-Next press the ALT key and hit the down arrow key
(this should drop down the file menu, if it doesn't please try ALT+F)
-Use the arrow key to scroll down to Add/Remove snap in and hit enter.
-Use the arrow key to scroll down to Device Manager and hit ALT+A to add the device manager to the console. Hit enter.
-Make sure local computer is selected if this menu comes up and hit enter.
-Hit enter one more time bringing you back to the console with the device manager added.
-Hit tab to get to the center console and scroll down to mouse.
(If tab isn't doing anything please hit the ALT key once.)
-Hit enter to open the tree if it isn't already
-Scroll down to mice and other pointing devices (or something along these lines) and hit the right arrow key to expand the tree again.
-Select the USB mouse with arrow keys
-Hit the alt key again then the down arrow (not together) and then the right arrow key until you get to the action menu and use the arrow key to go down to uninstall and hit enter.
-Wait a moment and then go back to the action menu (you may have to hit tab just keep trying tab and the down key (not together) until a menu opens. Go over to the action menu again and choose scan for hardware changes. The computer should recognize the mouse and now work.
I hope this helps you. Thank you.

I have a Toshiba Satellite T1300, the computers starts fine but the video screen is black.


Try to hook it up to an external monitor, if this works,your video card is working, Next Step.. then look on the laptop keyboard for a functiion key with a little picture of a screen on it, usually u have to hold down the fn key and hit F4, or F5 or F6 etc, look at the F keys at the top of the keyboard, and hold down function key at the bottom left of the keyboard, usually near the alt and ctrl keys, if you dont have a fn key (function key then hit ctr key, and at the same time hit the F key with screen pic on it, it might say lcd on key or be a box inside a box on the key. If this doesnt work try rebooting the laptop in safe mode by hitting F8 key before windows starts and go into safe mode. It is possible that a recent program or windows update that was installed is causing the blank screen. If the black screen happened after a new software install, delete that software while in safe mode. And reboot, Good Luck :)

Thinkpad 42 on startup screen is in a red pigment then goes to the blue welcome screen then goes completely black. On occasion may see my desktop for a moment.


This sounds like a display card (graphics card ) driver issue, or else the screen is going bad..

test that out by hooking up an external screen to the port on your laptop.. Then toggle using your function keys to use the external display..

If the external display allows you to see your desktop..

reload your graphics card driver, then boot up normally..

if the screen still doesnt work, you may need to replace it

Will not boot... black screen?


Try removing the battery completely and powering it up on AC power. Sometimes a dead battery (even if you're plugged in to AC) will stall a boot-up in its tracks. If this doesn't help, please reply back and let me know if anything changed.

Power Saver not working


The Logitech wireless keyboard "moon" key set the power saver on but would not return the screen no mater what key I hit. So, I connected a standard wired keyboard and hit the space bar. Once returned I disabled the "moon" key though the Logitech software.

Monitor not receiving data from computer?


If you did not hear any beep from your CPU, then the problem is in the system not the screen.
Try connecting the screen to another computer and try also a working screen of a friend to your computer...
You'll find out that either the screen or the computer...

Good luck... post me back for your result.
Don't forget to rate too.
