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
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

I've used it before but I completely overlooked the IECEE site. This is
a big help. At least I now know that the safety report exists in CB
format as well as report number and NCB. Now it's a matter of getting
them into my inbox. A big step in the right direction.
We've made some
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
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

That’s in the plan. This one slows down apparently when it’s not too busy. If
it’s just the OS running with no programs it’s cool as can be. But if I wanted
a laptop to only do one thing at a time I’d use MS-DOS. With several programs
running and multiple browsers with multiple windows it
Get a new laptop. Intel devices now slow down if they get too hot. My new
laptop barely gets warm.

I’d like
I’d like to ask the same question of my “name brand” laptop with the same
circumstances. The CPU runs just under 100 degrees F according to Intel
diagnostics and the case bottom runs hot enough it can’t actually sit on a lap.

Hello Carl,
There appears to be a CB Test Report and Test Certificate for this tablet. You
can check by going to the following link and search in the “Free Text” box for
SM-T820.

This doesn’t give you the Certificate, but should confirm one exists
I’ve had a similar situation where we use a tablet as a product’s user
interface module. Our NRTL required the tablet to have an NRTL listing. I
think that’s because there are specific safety testing requirements not just
for the battery but for its charge/discharge circuits and the tablet
Brian,
Li batteries and battery packs have conditions of acceptability that
must be confirmed within the end-use application. That is the hook in
this application. Our NRTL understandably must confirm this. I
consider our NRTL's willingness to accept the CB Cert and Report rather

The power supply is NRTL certified and the battery is NRTL certified. The rest
of the tablet I assume is limited energy circuit. Does the tablet require NRTL
certification?
