    My T40 too... seems only to happen when the laptop is jostled or if I plug in a USB device sometimes. Screen goes black and am pretty sure the backlight is off. The laptop is otherwise working, so I shut it down and reboot and the screen comes back.

    The same thing happened to my T40, it got progressively worse by the way. Getting it looked at now is the best way to do it, I found tapping or full out hitting the space to the right of the  mouse helpful, but I think I may have done permanent damage that way.

    unifi9230 Is this an easy in and out (of the case and motherboard) change of a board? No fine pitch solder or anything? Is this the same part you used? http://www.pchub.com/uph/laptop/43-28080... Thanks, Glenn nhpcfix at yahoo

First of all, you have to check whether you can see video signal with surrounding light tilting the screen.
If you can see dim image, all you have to do is replace back-light inverter or fix it. Usually, the fuse is open and you can connect it by simple soldering.
If you can't see dim image, it is another problems.
Give it a try.

I just replaced the inverter card on my T-40. This solved the problem of the screen going black after a sortly after booting.

Black screen right after dell logo


start tapping f8 after you boot the machine, when given the boot menu, try to load safe mode, and see if it loads. if it does, then you need to do a system restore back to before you got the black screen. more than likely windows loaded an updated driver that disagrees with your system. try that and let me know what happens :)

Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

My ibm laptop, was working great until this morning, the screen started to flicker, then the icons started to dim and completely disappear and then the screen went to a coloured test pattern and finally...


Check the power supply.Hope the notebook receives power from the battery or the Ac adapter.We need to ensure there is no issue with the power supply.boot the notebook to the safe mode.If it boots to the safemode perform a system restore.In case the notebook does not boot to the BIOS,connect to an external monitor.If we still do not get a display,its the video card

I have an IBM T40 Laptop and I wanted to display my video to the television screen via the SV output. When I hook everything up, all I see on the television is the Windows Desktop background, no icons etc....


You set it to Multiple Monitors (if you move the mouse, you will probably be able to see it on the TV once it "goes out" of the laptop desktop). You need to change output mode to external S-Video.

First of all try hitting Fn + F7 key to switch to Ext-S-Video. If it works, that's it, of course. If it doesn't, TV output is not enabled.

Right-click on the desktop to bring up the Properties, go to Settings. You'll see two monitor images there, 1 and 2.

Click Advanced, then go to Displays. You'll get CRT, TV and LCD. Turn on the TV button and tune your settings.

At this point, the hotkey Fn + F7 is enabled to cycle between LCD and TV.

If it still doesn't work and you see the blank desktop, go again in Display Properties, choose LCD as Primary Display, select Secondary, and verify that "Extend desktop on this display" is NOT checked.

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
