My computer's optical drive stopped working (CD/DVD thingy), and I couldn't find anyone savvy enough to help me replace it. I found some excellent instructions online, and ordered a replacement. Of course, since I needed to see the instructions on a computer to fix my computer, I went to the computer lab at school to fix it. I thought I had everything I needed, got halfway through, and came upon the part of the instructions that said to lay the logic board down on a soft cloth. I had nothing on me except my hoodie, and I was all in a rush because I was about to miss dinner at the dining commons, so I used the hoodie. I finish the process, and put it back together. And it won't turn on. Turns out, you're not supposed to put a logic board on polyester fabric because the static charge can destroy it. The hoodie was polyester fleece.
And I missed dinner anyway.
In sum, my computer died, I bought a new one (WITH the applecare insurance stuf), and will never attempt to fix a computer again.
