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!

SOURCE: my lenovo T400 will not shut down even when all

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..

SOURCE: my lenovo t400 has screen flickering when ever i

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

Hi sundar1968,


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,

mvincentc

White horizental lines across the LCD Monitor.


This is a high voltage horizontal output problem. Could just be a loose connection or an intermitant component failure. If you can get into it, check for any loose connections. Sometimes this can also be caused by a large accumulation of dust. Make sure you unplug it before opening it up.
