Question about IBM ThinkPad T22 2647 Notebook

1 Answer

Screen dark: Open/Close of lid makes screen bright

My Thinkpad T22 works well except for the dark background problem. I believe that if I re-seat the data flex cable into the motherboard it may solve the problem. My problem: How do I take the laptop apart without destroying it? I have worked on PCs for 7 years however never taken apart a laptop to the level which I require. Sometimes when I start Laptop it beeps at me telling me (I beleive) the data flex cable is not seated properly. If I open/close lid it starts without beeping and screen lighted well. Thank you for your time. - Todd

T22 disk read error

Sounds like the Operating System is corrupt. I would re-format the hard drive and re-install the OS that should solve the problem. If not then the Hard drive needs to be replaced.

Dark monitor

If your LCD screen on your laptop is really dark and pressing the brightness function keys does not make it any better then you probably have a failing backlight. This pretty much means, time to either replace the screen altogether or buy a new laptop.
You can get screens off ebay for about $130

IBM T22 screen is dark is there a bulb that can be replaced?

Usually it's the inverter than needs to be replaced and not the bulb (backlight).

Here's some more info here.

Basically you just need to swap the inverter and you're good to go.

Can barley see screen on t22 thinkpad

It might be that the power supply, battery, or backlight. Try pulling the battery out using just the power supply. If you have another power supply try that also.

No visual display

Function F7 will enable the external video monitor connection and will toggle between the screen, the screen plus external monitor, and the external monitor only. Try hitting function F7 and see if that helps. Also there is a small switch that is activated when you close hte lid to turn off the display when the lid is closed. make sure that this little switch is not stuck.

How do I find my Thinkpad 2647 cmos battery, to change it?

It is unlikely to be the cmos battery as there are signs [music] that your laptop is booting - shine a light into the screen if you can see an image but it is very dark then it is likely that the screen backlight is not working. If this is the case the most likely causes are a faulty inverter or a faulty screen cable - both can be obtained as a kit quite cheaply on ebay if you have the ability to fit them.

Faint picture on screen

Most likely the backlight on your LCD has gone out. See for a guide on replacing the backlight.
