Hi Brian – my TV engineer says:-

“Heat is an issue because laptops are not laptops as they are designed to be used on a hard surface. This can be overcome by using a TV dinner tray - the type with a bean bag underneath and a hard top. Running 24/7 is not good without extra cooling. This can be overcome by using a cooling tray between the laptop and the TV tray.”

Have a look at http://crave.cnet.com/8301-1_105-9700201-1.html or type in laptop coolers and have a look around.

Over here in the UK we don’t get hot enough for anything other than a bean bag tray
Such as http://www.sawitfirst.co.uk/content/inglesbbeanbag_tray . This is a boon for comfortable laptop work.

Hope this may help
