IBM Thinkpad AC Adapter Problem

Hi, I've scoured the IBM/Lenovo site with (predictably) no luck . . .
I'm having a problem with my AC Adapter/Power Brick for my IBM/Lenovo X41 Tablet laptop. It keeps beeping while it's plugged in to the wall (regardless of whether it's plugged into the actual computer). While it's beeping, it does not send power to the laptop . . .
Sometimes it'll stop beeping, and work just fine. But recently, whenever it's moved around (if it accidently gets knocked off the desk, for example) it'll start beeping again. And not only will it stop powering the laptop, it'll cause my laptop to completely freeze up, forcing me to power it down and reboot it (which sucks, since the harddrive on this POS is as slow as molasses and it takes 10 minutes to boot).
Anyways, I was wondering what the beeping on my power brick means - is it a general error signal? I don't think it's an overheating issue, it beeps immediately after I plug it in for the first time in the day. Can I fix it? Do I really have to fork over more money to Lenovo when I've already been disappointed in their product for almost 2 years? Can you tell I've punched a hole in the wall over the frustration of not being able to use my laptop? Am I allowed to urge people not to buy IBM/Lenovo over one anecdotal poor experience?

Anyways, any help is, as always, appreciated.
 
I found this in another forum - it does seem to relate:

"Another reader has a ThinkPad 2621 that started beeping every time he accidentally bumped the power connector. Apparently the beep meant that the AC power was no longer charging the machine. This went on for about a month and finally the brand new battery would no longer charge. He assumed that a wire was probably loose and tried take a part the machine for two days but gave up when he couldn't figure how to do it without breaking the case. He then took it to a computer repair shop that fixed it for $100 dollars. August 14, 2004."

My sense is that the A/C adapter is defective and you need to swap it.
 
youare triggering the current over load circuit. The supply is shorting somehow. Since it beeps with out a load attatched, nou need a new one.
