Question about IBM Lenovo ThinkPad T400 7417 Notebook
I see that you have a "z" light indicator on the system when powered ON but you see no video on the screen.
The "z" Indicator means that the system is turned ON and ready to use but is in standby mode.
To disable standby mode on your system simply press the FN button for about 5 seconds on the system make sure that the machine is turned ON, this will make you system go back to normal mode.
For additional info on the issue the system can be put to standby mode by holding down the FN+F4 for a second or two this will enable standby mode on your Thinpad T400 and to disable the standbymode press and hold down FN for 5 seconds.
I hope that this will be of help regarding you concern, have a nice day.

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.
