A good laptop has proper cooling and doesn't require mats, fans, etc. as long as it's not on a soft surface (softer than a thin table cloth) or lap and it's not clogged up with dust. I am so sick of people bringing in ****ty laptops for service that are designed first for looks, and second for function. Get a T-series Lenovo (even SL-series) instead of the $3-400 Acer and these problems could be avoided. I've never once needed to worry about my personal laptop overheating, unless possibly if it was laying on carpet for an extended period of time, etc. Tables should always be fine, even with a tablecloth, and for Pete's sake, those "cooling pads" with the fans are a joke.
Sorry. There have been a lot of this crap coming in and we're supposed to work miracles with it and it's starting to get to me.
Sorry for the siderant... feel free to ignore.
