While there haven't been any heating problems before this, I've been using this piece of shit for three years or so, which means it probably has collected more than its fair share of lint and dust that can be found in abudance in my student box. Never opened a laptop before though, so I am waiting a few more days for my friend to come back to town (he works with computers) to make sure I won't fuck anything up.
Luckily I am dumping this one at some point during the summer.
