Hi Everyone, This "hot laptop" problem has been going on for many years now. I remember a story in the tech mags out of Silicon Valley about Apple laptops burning, really leaving an injury, on the order of ten years ago. Apple said the machines were not intended to be used on one's lap. Doug On Thu, 16 Aug 2018 20:58:12 +0000, "Nyffenegger, Dave" wrote: We agree I need a new laptop due to this issue alone. It’s not hot enough that it can’t be moved away quickly enough to prevent a permanent burn. But it is hot enough to leave sun-burn like splotches on skin if left to long over a thin layer of clothing. Hot enough to discolor some other materials it may rest on as well. -Dave From: Richard Nute [mailto:ri...@ieee.org] Sent: Thursday, August 16, 2018 3:44 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] hot laptop Its not the temperature, but the thermal energy that is transferred to a body part. Consider aluminum foil versus cast aluminum at the same temperature, say 140 F. The foil won’t burn you, but the cast aluminum sure will! The thermal resistance of plastic will give you the time to disconnect from the 140 F surface of your laptop before you suffer a burn. You need a new laptop, too! 😊 Best regards, Rich From: IBM Ken <ibm...@gmail.com> Sent: Thursday, August 16, 2018 12:31 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] hot laptop Aren't we supposed to call them "notebook" computers now, so it can be claimed they're not intended for use on a lap? For what it's worth, I've measured up to 140F on the surface of my computer... - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
