Re: IBM T22 Screen goes very dim and normal automatically

Because the LCD background light is intermittent, sometimes working well, sometimes not, it is not the light itself but rather the LCD inverter board that sounds flaky.
This board controls the high voltage necessary to power the flourescent lamp.  You can find them for cheap "google for T22 LCD Inverter" and replacement instructions can also be found online

Sounds like the LCD background light is either loose or going bad

My IBM thinkpad is not working

If you hear the hard drive spinning and you think Windows is working but you can't see an image then :-
You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:

  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

IBM T22 Thinkpad won't boot up - not even in safe mode

either you have a virus or a corrupted dll file.
eitherway, beside create a bootable CD or Floppy disk, and try to fix from there, thats' time a money.
the next best thing, is to reinsall the operating system.
the other option is get a new hard drive and install the operating system on that so you can preserve the data you have on the old one.

Ok, I want this off my screen. If it is stuck in standby mode as you say, press and hold the power button until the computer goes "dead." Then turn it back on. If this doesn't work, unplug it and take the battery out for a while.

Sorry, but no function key for this. This will most likely be a hard drive failure. Start by do a system repair with your recovery or operating system disc. If the repair doesn't take, then reformat the hard drive, using a full NTFS format not the quick, and install a new operating system. If the hard drive will not format, or you have any issues during or after the install, then the hard drive has failed and will need replaced.

IBM Think Pad T22 auto -shut down a few minutes

Try running it without the battery. Sometimes an IBM battery can develop a short and cause this. If it still does it without the battery, I'm afraid it's the power management chip on the motherboard, and the motherboard will need to be replaced.
