If you're unlucky you'll fry the motherboard and/or other components with static electricity.
Use an air blower to get ride of the dust, such as a hair dryer even.
My dad used to do that with our last television, which was overdue for a much needed replacement for many years. I still want to punch him in the noggin for not getting a HD TV. In his defense, those were more expensive back then.
I'm F'in pissed off today. Nailed my Management & Organisation exam, got a 7,8 for it, but my project group failed to pass this period's project. We had to use statistic tests to check the validity of the research we had carried out. While the paper was less than stellar compared to some of my previous projects, it was enough to pass. We got nailed on the statistics. We didn't even make glaringly big mistakes, just too many small ones. This is exactly why i HATE education by projects, you're dependent on your teammates, for good or better. I did not do any of the statistics, was told they were correct, and yet we still end up not making it. I wasn't going to make my Propedeuse(all 60 ects for the first academical year in one year) regardless, but now i gott hit by another 5 ECTS slug to the chest. Instead of 58 out of 60 ECTS i can now get 53. That is, if i pass all remaining exams... **** sucks.
I feel bad for one of the girls in the team. She's a really nice girl, who worked her ass of this year, got all 9's and 10's but ends up getting nailed because of a bunch of silly little mistakes. She's going to Art Management(at least she hopes she'll get in) next year, and 'll probably get a lot of the stuff she did her accredited so she can get exemption for those subjects, but she still really wanted that paper.
So, the girl on my team who i posted about earlier, called. Said she's taking this to the exam comittee. Don't know what she thinks we'll get out of it, but if we get one last chance this year, she's got my support.
