Nasty Burn Marks on Case

[capo64]

I started to notice burn marks on the bottom of my MacBook case. I was just wondering if this kinda thing is normal because they've gotten pretty bad. I can even see some under the keys as well. Here's some pictures.

I bought the MacBook brand new in June, so it's still under warranty.

I expected to find something on Google or the forums about this but I couldn't find anything except burn marks on the display.

Although the marks aren't appealing, I can deal with them. I just want to make sure my hardware isn't in danger

That definitely doesn't look normal! Do you have something like iStat to see the inside temperatures? Something has to definitely be overheating.

those are user inflicted.

judging by the condition of that thing anything could have happened.

Those look like abrasion marks. They're lined up with the edge of the bevel. I would say to look at what you're resting the MBP on, as there are a lot of scratches near the abrasions, too.

Not sure what to tell you about the keyboard. The marks have a yellowish cast, so I was wondering if you smoked? Air circulates down through the openings around the keys, which could leave traces of smoke residue. The only only other thing that touches the frame there are hands - not much to say about that.

I can't think of anything that could get hot enough to cause those marks without damaging components - and not get noticed immediately. There are no components touching the bottom case or keyboard in those areas.

I was thinking the abrasion thing as soon as i saw it, are your rubber feet still pretty tall? I can see them wearing out if you use your computer a lot, and after they wear your bottom case is going to be resting on the table/surface you use your computer on.

On second thought, if you feel brave enough open the bottom up and see what the inside of the case looks like.

Well I took it to the Apple store and they said they'll replace it (the casing). The guy told me it was a scratch, and they wouldn't normally cover it, but I was a special case?

Anyway, I don't smoke cigarettes so I don't think it's that, but this thing has been sitting on my college desk for the past 7 months or so. I only take it to one class, and I put it in a separate padded pocket in my backpack that's there specially for laptops. I really don't think I've been rough enough to do something like that to it.

He said they'll run diagnostics on it to see if anything is especially wrong with it.

Glad they're helping out. I know they normally will, if at all possible.

You might be able to do something about the keyboard marks using a damp cloth or some iKlear/Klear Screen. Of course, make sure the cloth is damp - not wet enough to get water inside.

Wow!

That must have reached a pretty high temperature to leave those kinds of marks.

Yep the guys at the apple store actually wiped them off right in front of me. Kinda made me feel like i was being dramatic, but I wanted them to see as much damage as possible to give me a better chance of replacement
