Question about IBM ThinkPad T23 2647 Notebook
Have a IBM ThinkPad T23. When powering on last night for some reason there was nothing showing on the screen. I have plugged my desktop monitor in to see if any errors showed but it booted up ok and everything proceeded to work without any issue.
When putting it into hibernate briefly on the Laptop screen you can see the image but its almost as if looking at a shadow, its very very dark, I have tried increasing the brightness using the fn keys but this made no difference.
Is there any key press that could have been done inadvertantly to cause this? Or does anyone hae any idea what to try next.
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.
