Question about Lenovo ThinkPad Computers & Internet
It's a bad LCD. Replace it. Horizontal or Vertical lines are indications of LCD issue and can only be resolved by replacing the screen itself. Same with dead pixels. Sorry!

Hi guest, try to turn off the pc by using the power button. Then remove the cables and battery on the laptop. Then push & hold the power button for 5 seconds. Reinsert the cables and battery then turn on the pc.
Check if you will be able to shut down your pc using the operating system..

Sounds like a problem with the video adapter chip. The chip might be either defective or experiencing bad connection with the motherboard. In order to fix this problem, you will need to disassemble the notebook, pull out the motherboard & inspect the video chip & its connection points to the motherboard. If the video chip is defective, you might have to replace the motherboard.

SOURCE: when i start Lenovo thinkpad
I see that your Thinkpad T400 machine is locked and you are unable to make use of the machine.
to be able to unlock the machine power the system on once turned ON you will see a Lock icon on the center of the screen just press and hold down the FN key for at least 5-7 seconds or if possible untill the lock icons shows that it is unlocked.
This should help you with your concern.
Have a nice day,
