Hey guys, my girlfriend just got a 14" T60p, and i noticed that her power brick doesn't make noise!!! She has a Revision 5 and it's silent, but my revision 3 is loud! Anyone else having the same problem?

Wow, I have owned a lot of Thinkpads. I used to work at a company that used IBM exclusively (over 500 users probably 200 or so Thinkpads) and I have never seen a power brick that makes "noise". What kind of noise does it make? I am pretty sure there are no moving parts in there, so, um, wow.

If it's noisy, have it replaced

You happen to be lucky enough to hear either the transformer or capacitors switching it seems

There are some variances, but usually it is a very quiet thing that is only audible in a room or when you put your ear close to the brick.

I wonder what the differences in the Revisions are to cause such a difference.

AC producing loud \"sounds\" means something is loose inside. Please contact IBM/Lenovo support and tell them to replace another AC for you.

Try using a power supply with a "ground" connection (3 holes) and see if your problem persists. If it does, please get it replaced.
