How I destroyed my chipset using an external hard disk

So the other day I realised that my external Western Digital MyBook hard disk (2009 model, one of those that needs its own power adaptor) was unmounting and mounting every half an hour or so. I checked the back of the hard disk and realised that the mini USB port was loose. In a short while it was completely broken off.

I then started reading about WD MyBooks and all sorts of problems you might have when something as simple as a mini usb port breaks off. This is supposedly because WD MyBooks have hardware encryption, and if soldering the port back in somehow fails (i.e. if you cannot use the same circuit board any more), then you can forget about recovering your irreplaceable data without paying >700 bucks.

I thought, and I really did think it was not that stupid, "if I just hold this mini USB port steadily for a few minutes on exactly the spot where it broke off from, I might save some of my very important data". I did this, and the WD seemed like it was powering up/working twice in ten seconds. Then all of a sudden my laptop (Sony Vaio SVS1513C5E) shutdown. It wouldn't turn on and the green light that's up when the power adaptor is connected was not there anymore. The weirdest thing is that after this happened, somehow Vaio's hard disk continued working for more than 10 hours --I could hear it working when I put my ear on the bottom of the case.

I took my laptop and WD hard disk to a repair shop and the employee told me he could easily fix the WD hard disk (broken usb port) and he'd need to have a look at the laptop. A few hours later he said the chipset was fried and that was the only part he needed to order to fix the issue. Other small components that were damaged/destroyed he had in his store. He said in total it'd cost me 200 Euro, or something in that ballpark.

Now at this point I have a few questions:
1- Why would the internal hard disk continue to work/be powered when the rest of the laptop was completely off and unresponsive even to the power cable being attached (no 'charging light')?

2- Is it really possible that the damage is predominantly on the chipset and the rest of the main components are in shape, other than those small components that he said he could replace (I assume he means a few small electronic units on the motherboard). If so, how?

3- What are the consequences of having a new chipset? He said the one he'll order costs 125 Euro. He also said that the chances of repair was 50-50: sometimes it works and sometimes it doesn't. In case it doesn't, will the laptop still be approachable by another repairman?

Thank you very much in advance for going through my post and answering my questions.

Edit: the external HD is fixed and working.

Oh, that's a bit different story. For that external disk, maybe it can be taken out of the box, inside should be a normal SATA disk which could be placed in another enclosure, data is most probably safe in it.
If chipset was damaged it can be changed but it requires special tools. Used one shouldn't be problem either if he guarantees it would work. New or used should not have any consequences because it would have to be identical as old one.
It would be possible to damage chipset if it had short or wrong power because of bad USB device as everything goes thru and is controlled by it.

Hi CountMike, sorry there was a problem with editing my original post. Please see the original post again (edited) and perhaps edit your answer. After that I'll remove this (second) post of mine.

Thank you very much for your answer.

I wish you could do what you suggested with the external hd. The reason I started playing around with the broken mini usb port in the first place is this hardware encryption issue. Anyway, it is fortunately fixed now and my data is safe (see the fix for a work of art).

Coming to the fried Intel chip, I've indeed read in many forums that the fix is not an easy one because of the complexity of how chips are connected to motherboards. As I wrote, the repairman said that the chances of success with a new chip is 50-50: sometimes the fix works and sometimes it doesn't. I'm really wondering, in case it doesn't, will the laptop still be approachable by another repairman? Because the new chip hasn't arrived yet, and if in case of failure it won't be approachable by another shop, maybe I should just take it to someone else who thinks his chances are higher. The reason I'm trying to save this laptop is that it is an expensive, high-end Vaio without an alternative in the market as a replacement.
