Hope this will answer your question.

There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

If this did not work, try also disassembling the laptop & make sure that all main components are seated properly. Also make sure that all ribbon cables interconnecting the various components of the laptop are tightly connected.

Have you tried to connect your laptop to external monitor?
If you get normal picture on external monitor, then you need to replace LCD screen, but if you get same picture on external screen, then unfortunately you will need new motherboard, because graphics card is integrated to motherboard.

1st update the chipset drivers & then update the audio & wireless drivers.

Go to the IBM/Lenovo WEB site - support/download page and download the latest Windows XP or Vista device drivers for your model laptop,

IBM uses a security chip on the motherboard that burns the password into it when a bios password is enabled. The only solution to getting around a bios password on an IBM is to replace the bios security chip or the motherboard. I've wrestled with this before, and believe me when I say it's a whole lot easier to replace the board. Do your best to remember!!!!!!!!
