Heat and numbness in leg from MacBook Pro

I started using bean bag type tray table to distance the laptop from my legs because if was too warm directly on my legs.

That didnt last long. I recently bought a Belkin Cool Tray which worked for about a week.

I still experience heat in my legs that is uncomfortable and a slight tingling numbness in my left leg.

I hear Im not the only one and some report pain.

Any thoughgts?

MacBook Pro (13-inch, Mid 2012)

Consult a doctor, I doubt very much it's caused by the heat of the laptop, more like sitting hunced over to see it's tiny 13" screen and your either pinching a nerve or cutting off blood supply to your left leg.


Apple calls their laptops "notebooks" as they are really not designed to be used on the lap, rather on a table or desk.

Modern self contained computers are NOT LAPTOPS. They are Notebook computers and should not be used in your LAP.



Steve?... is that you? Are you back from the dead? :rolleyes:


Let me guess... you're holding it wrong.


100% of all other laptops in the world can be used in one's lap without scalding anyone and Apple thinks they can get away with it. lol

Not according to HP:


WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not place the computer directly on your lap or obstruct the computer air vents. Use the computer only on a hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to come into contact with the skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer and the AC adapter comply with the user-accessible surface temperature limits defined by the International Standard for Safety of Information Technology Equipment (IEC 60950).

Ya, that's bs. I haven't found a single computer that I haven't been able to use on my lap without issues, including my 13" MBP. And yes, I've used it even on bare skin and it's not a problem. However, out of all the laptops I've had over the years, the MBP is the one that heats up the quickest and cools off the quickest if set on something cold for a few seconds to pull the heat away from the unibody.


Either way, Apple really does need to come up with a better way to shed the heat through the air vents better than it currently does. The current fan/airvent/heatsink designs just aren't up to snuff. Yes, they work at idle/normal use, but if you start pumping out anything through the WIFI card for traffic or spike the CPU just a bit even up to 25% sustained, it gets pretty hot. That's kind of rediculous when you think about it. They need a better heatpipe design on all chips (like the network card) and not just the video/cpu/main chipsets and nothing else.
