The barrel sockets on the motherboard that connect to
the barrel plug on the AC adapter can fail; it's a high
stress point.  I've replaced a few.  Some are soldered,
some connect with a plug.

Some thinkpads are sheer hell to tear down to reach that
socket (or the fan, which also fails), some are easier.

Some teardowns require removing the heatsink from the CPU.
If so, you will need replacement thermal compound before
you start.  

When you tear down, find a copy of the Hardware Maintenance
Manual if possible.  Also, use a plastic ice cube tray
to store the screws in the order that you remove them. 
Tape the tray down firmly, you don't want it tumbling. 
Take copious notes, and photos if possible. 

Pay attention, avoid distractions, lock the spouse and
children and pets in a closet, then savor your first
teardown, and the glow of pride when it almost works. 
Don't forget to unlock the closet.
