Alright, I've actually talked to the technician. He was rather hard to understand, he has a really strong accent. Sounded Indian or something. And I don't think he likes you.
I talked to the store manager first, and explained your dissatisfaction. He said he "couldn't talk tech" with me, because he's just the store manager and wasn't very knowledgeable about that stuff. I asked him if he minded if I talked to the tech myself, and he was more than happy to put him on.

As soon as I told the technician why I was calling, his tone completely changed. At first he wasn't very cooperative and I could tell he didn't want to explain it to me, but I pushed him to explain...... basically, he has no idea what's wrong (he even admitted that eventually) with it and I am inclined to believe he doesn't really know what he's doing.
First he brought up the update thing. Then he tried feeding me a line about a virus killing the motherboard and wiping the hard drive. He said he's seen it happen quite a bit. I asked him to name a single virus that would render a motherboard inoperable and wipe a hard drive. He turned the question around and asked me, I said there isn't one and that was nonsense. Then he tried to bring up the fact that it was dropped 4 months ago and that's caused all the motherboard to fail. I asked him what made him so sure it was just a motherboard failure, then he said something about the video card. I reminded him that laptops don't have video card, it's integrated. Then he finally came out and admitted it. He said, and I quote "I actually don't know what's wrong with it. I've never seen this before," referring to the motherboard dying and the hard drive being empty. He said when he turns it on, nothing happens, so he thinks it's the board.
Unfortunately, the laptop has already been sent off to another place for a proper diagnostic at whatever company they use, apparently by real techs, not him. When they find the issue, supposedly they'll email him and he'll notify you.
He did mention that the normal cost of replacing the board, if that is indeed the issue, is $360, but you're only being charge $100 for some reason he couldn't (or wouldn't) explain to me.
