guys I'm really freaking out here, can I ask for some of your time to help me with this. On sunday I got a problem with my macbook: I heard a really loud, mechanical sound coming from the bottom of the MB. It went, 'CLACK. whirr...CLACK. whirr...CLACK. whirr' (ie a loud clack, followed by a softer whirr, then a short pause of a second or so, then clack again and so on). It did this as I was shutting down: started a couple of seconds after I clicked Shut Down, then stopped once the screen went blank (the noise was the only thing out of the ordinary in the shut down. The action on the screen was what it always is when it's shutting down). I decided to shut down in the first place because I'd noticed it was doing weird stuff before, first in Safari where I was browsing, then when I had all windows closed (applications still running though). What it did in Safari was, it would load pages, then take me straight to the bottom of them and not allow me to scroll up (it would scroll a little then slide back down), plus if I clicked on one of the Menus like File or Bookmarks, it wouldn't stay open once I released the mouse button. So I decide to shut down all the apps and see if there were any updates I'd not installed (unlikely since I'm really careful to always install when I get the messages, but still), when I started to hear this loud TRRRRRRRRRR sound. It was exactly the same sound, tone, pitch and everything as the one the MB produces when you've got hot corners activated to show you all the windows you have running (say), but you take the mouse pointer to the corner when you have no windows open at all. You can try it if you want, it does a short, slightly ascending trrrt! This time it did the same thing, exactly only really extended: trrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr. That freaked me proper, so I shut down, and got the other sound I described above, which was even more worrying. Still it was sunday, so there was nothing to do, and I just left it there and didn't turn it on 'til monday morning. When I did, it booted up and then shut down as usual, no problems. Still it was a scary thing so I took it straight in to the repair place to see if they could figure out why it did that and more importantly if it's something needing to be fixed. And here we get to why I need your help. Where I am Apple is not present as a company, so apple products get distributed by another company called Rainbow, who have a deal with Apple to import these computers (ipods too), and sell them themselves through their website or via a number of 'authorized resellers' (some of them big box chains). these rainbow people take care of the repairs while the machines are under warranty (1 year, no applecare available). It's a cr@ppy system run by a company with a less than ideal reputation, but I figured when I bought my MB in december I wouldn't have to contend with them since I was due to move abroad well before the end of the warranty period, and the MB was unlikely to flip in that time, so I wouldn't have to mess with them but it turns out I was wrong! So I needed your input and ideas on what could be wrong with my computer, because I know there's quite a few of you guys here who have owned and repaired macs and generally computers for many years, so I thought I'd draw on all that experience to get an idea of what's going on, because they told me they would take a minimum of five to seven working days (ie until the middle of nest week) to see what's wrong with my machine, and more to get it repaired if there's a need for parts. But right now I was writing something on it that I need to hand in soon, and if it takes so long, I just lose all hope of meeting my deadline because I just don't have access to another computer (I have the file on both time machine and a thumb drive, but no computer to use them with) It is too long to stay without a computer at this stage in the proceedings where I am collating all my information and making it into text--I tried to do it by writing it out on paper, but it took twice as long that way, and it was an easy section too, all dates and stuff! If I miss the deadline, my next chance if any will be next year I spoke to them about this this morning (after some really Dell-like experiences with the phone people), and the technician person got snappy and told me that if I didn't like it, I should just come and retrieve my computer without having it looked at.But what if it gets worse after? what if I'm running Keynote there with ,y presentation going and halfway through it begins to act funny? Maybe I'll have to do that eventually, but first I wanted to pick you guys' brains as to what it could be, so I can have some kind of an idea what risk I'm running by not letting them check it. I'm really scared, I dunno what's gonna happen with this anymore. I thought I was through this stuff I still like my computer but I'm even scared they'll mess it up even worse, I don't trust them like I would a real Apple Store after all I've read about those here and elsewhere. thanks for patiently reading this y'all, sorry I lose all ability to be concise when I'm stressed out like that, and I'm stressed as hell.
