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 <[email protected]> Sent: Thursday, August 16, 2018 12:31 PM To: [email protected] 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.
