I've got an R40 2722-CDG which probably uses the same AC adapter.

I had the exact same problem: the adapter would get so hot that you couldn't
really hold it in your hand. Also the adapter made high-pitched chirping
noises when the laptop was using a lot of power (hdd activity, scrolling a
webpage, etc.)

I called IBM Support and described the problem. They sent me a new adapter
which I received 2 days later and this one only gets warm (and makes no
noises) so I guess the old one was indeed defective.

HTH,
