I have a IBM Thinkpad 2629
When the computer first starts up there is a pinkish hue to the screen and after a few minutes the screen goes black. if I press the lid close button the screen will come back on for a few more minutes but then go black again.. I can do this over and over again.. I've turned off all the suspension and hibernation settings i the bios and that didn't help..
My thoughts where the screen inverter or the video circuit on the mother board... other that this the computer runs fine... this happens even before the system goes to boot into Windows so I excluded windows being the problem...

Test with an external monitor. If it works, it is the display's backlight or inverter board.
If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.
Since you are getting the IBM Thinkpad Logo it is confirmed that you have no hardware error. All you need to do is restore the operating system. most of the IBM laptop has an inbuilt recovery option. just press the access IBM/ Thinkvantage (blue button) immediately after pressing the power button and follow the screen..
The backlight is the light bult that illuminates the screen. Before it finally goes out completely it will turn your screen a pink color on startup (and then usually become brighter and the pink fades). It is also possible that the backlight, also called a Cold Cathode Flourescent Light, CCFL, died an immediate death. But usually they take a while and signal with the "PINKNESS" first. If you found that your computer is working just fine connected to an external monitor (and you moved the base of your laptop around while connected to the monitor to be sure and left the computer on for a long time) then you have verified that the screen is the problem. It is usually two things: (1) the inverter, a circuit board that increases the voltage to supply the LCD which eats around 700 volts (yeah baby); or (2) the backlight itself. The first problem is a relatively easy and inexpensive fix. You can find how to replace an inverter by downloading the Hardware Maintenance Manual for the T40, T41, etc., from IBM/Lenovo's site. Replacing the backlight itself, a bulb that is like a strand of speghetti and even more delicate, is a tougher job. I would suggest purchasing a replacement screen in that event rather than replacing the backlight yourself. (The HMM probably does not show you how to replace the backlight/CCFL as it is a potentially dangerous job.) That suggestion assumes you can find a cost-effective replacement screen and do not mind opening the TP and putting the new screen in. At least look at the HMM to see what is involved. Good luck.
im sorry to say this laptop is just not fast enuf to run windows XP you best bet for this would be to run windows 98 or a distro of linux that fits your needs
there are no bios updates at this time that will allow you to install XP on this system. sorry
This is an known problem I think you must replace the backlight: look for example ebay partnr:
260327530145 only for example if this is your problem.
