Hard drive was removed while power was on

My wife's MacBook Pro mid-2010 had its hard drive removed by, let's say, a person less than qualified to do so, for reasons not relevant to the question. When I opened the case to "assess the damage" and to get an idea of what I had to do to replace the drive, I inadvertently tried to remove the wrong bracket, the one closer to the front, by mistake. To my dismay, I noticed that the white bar LED, hidden behind the bracket, was on. There's a circuit board loosely attached to the LED behind the bracket. I hope I didn't damage that. I had wrongly assumed that the, ah, bozo would have turned the unit off, or more correctly, never turned it on, before removing the drive. I also wrongly assumed that the unit would not be on in the first place, with the drive missing. Apparently it can still be turned on (for hardware tests?). I also thought it would have auto-shut long since the 4 days ago that the drive was removed.The desktop and dock were visible when I opened the cover.

My question is, could removing the drive while the unit was powered on have done serious damage? Is it possible that the unit turned on AFTER the drive was removed with the power off?

Also, the 4 mounting (torx?) screws from the drive are missing. Do most drives come with these or can I get some from here when I order a new drive?

Another anomaly, there were only 2 long screws at the back of the case instead of the 3 that are shown in the manual. The third one is a short screw and the threads are all the way to the top surface of the cover so it appears to be intentional. What's up with that?

Update

Conclusion

I installed a new 750 GB 7200 rpm SATA II WD Scorpio Black WD7500BPKT drive. I formatted the drive using Disk Utilities and installed OS X and default apps from supplied discs. I updated OS X to version 10.6.7 and all seems to be working well. I ran the Apple Hardware Test and, after almost an hour, got the coveted results: "No trouble found." WHEW! So maybe the guy wasn't a total half-wit. ;) Thanks all for your help. I hope others will find this first-hand information useful.

First, I think you're looking at the wrong manual. If your machine is a 2010 it's a Unibody. The icon you've put up is for the previous models and the teardown is completely different. This is going to change half of your questions. If appears that the bozo has continued his ways, please ask him to leave and we can get this thing fixed. If you give me the last three figures of your serial number, I will change the selection and post the correct guide. Next, are you replacing the drive, if so may we know the reason. If you have already bought a new drive, please list what you got and if it is new or used. Also do you have your original installation disk or a full install version of 10.6?

Icon? What icon? The manual, MacBook_Pro_13inch_Mid2010.pdf is for my product number MC374LL/A straight from Apple. I thought I made it clear that I am replacing the now defunct drive with an, as yet unbought, new drive. I have both unused installation discs that came with the original packaging but that is the least of my worries. My concerns right now are 1.) how much damage could this half-wit have caused and 2.) if a new drive doesn't come with the 4 torx? screws, what are the specs of the screws so I can get some? Do they even have to be torx? As far as the third screw being a small one, it's probably not important but I am just curious if some revs had this anomaly or if mine is unique.

Actually I can find no mention of a new drive in your original question.. As to damage done by removing the drive, probably none. It's more likely to cause damage when connecting a hot drive.

Great. I finally found a local source for these for $10 / set plus gas plus tax but they have them in stock and I don't have to wait, so, not bad.

Please share your source so the next guy doesn't have to jump through the hoops you did. Thanks

I thought of doing that but this is a small local Apple repair shop and I think they were doing me a favor. And they wouldn't just mail it to me. I have to travel 30 minutes to pick it up. The best bet is to search Google Maps for the closest Apple repair shop. That's what I did.

It' always a good idea to unplug the battery before working on the guts. Easily done on theses machines when the back is off. If everything is working fine with the drive back in, why worry?

The hardrive always has four torx pins, if they are missing you ought to get some. Here, for example.

Normally there are always 3 long and one short screw at the back.

I did a lot of searching and everyone is very proud of these screws. The cheapest I found was $19

I might make a batch with my trusty old Emco Unimat ;-)
