I recently bought two Dell Inpiron 1501 laptops, one for myself and one for my wife, and for some reason mine seems to get hot as hell as well. What I have noticed is:
- Even using the battery on low power consumption with the wifi off, the right side, where the hard drive is located gets extremely hot.
- The heat is worse with the AC Adapter in, with the battery in or out of the computer.
- The battery itself is always cool.
And most importantly,
- It seems that the computer was designed to use the hard drive as a heatsink!!
I looked up a picture of the motherboard on the internet and it seems that there aren't any heat sinks on the power regulators, nor given the location of the northbridge, is there any vented heatsink for it either. That is a huge oversight.
I'm writing this from my laptop, which is sitting on a piece of nicely painted MDF board, which started its life as part of a packing crate (reduce, reuse, recycle!), so it's not as though I am blocking the vents. In fact, I have even tried propping it up on my daughters foam blocks, one in each corner, but even over 1.5" off the wooden surface, my legs are still warmed up by the machine - through the MDF board!
I'm not sure what we can do about the issue. Dell tech support is pretty useless in my experience. I do have friends that work at the Dell Canada tech support center who know about the issue... I'll poke around and see what's what.
