    Also could it be risky to use the notebook for extended periods of time on your lap?

    It is usually in the hinge that connects the screen and rest of the body. And I do not believe that it would be risky for the computer to be used for extended periods of time on your lap.

    Only the 15-inch is dangerous... The 13-incher doesn't bite

    But if anything surely the 13" would be more dangerous especially for your fertility as it runs at a higher temp due to having only 1 fan, less vents, and less surface estate over which to dissipate the heat.

    I heard it maybe in the top lid.

    oh please, no more 13" hate threads.

    this is getting really annoying.

    shamwow needs a PC. A new day, a new 13"MBP bashing opportunity.

    You need to use that 15" badboy to do something productive besides surfing MR. WoW works great on it!

    the antenna is the display, or part of it. i think so anyway, i read that somewhere.

    I think we could be starting to enter the realms of pseudo-science here.
    I find it hard to believe that there could be any effect on your genitals from the heat of your laptop, remember the testicles are kept approxaimately 1-3 degree centigrade below core body temperature (37 centrigrade), and the scrotum will raise or lower the testicles depending on ambient temperature (action of the Dartos muscle in the scrotum).

    Also wifi is not microwave, and I am not aware of any heating element associated with wifi, unlike microwaves (which effectively cook the water molecules), wifi signal is all around as well, just like mobiles.

    Ultimately I would be very surprised to discover any complications associated from using your laptop in your lap.....

    Certainly as a doctor I have never encountered any such publication dealing with this, but if anyone else has any please do let me know.

    Perhaps greater concerns for fertility
    Hot baths
    Increasing use of oestrogens in everyday items
    sexually transmitted diseases
    Poorly fitted underwear

    Oh and I think the comment about the 13incher not biting could be a joke, unless you trapped your genitals in its lid - which then could be harmful to your fertility :)

    Well I've read a report that children have already been advised against using laptops on their laps because the long-term effects of WiFi are unknown. Hardly reassuring.

    That's not a report, per se... that's a blog entry. You can also find, with equal authority, blog reports that say coffee is good for you; coffee is bad for you; Aspertame makes you skinny/fat/cancerous/healthy; and so on.

    Two words: Peer Review.

    The 15" badbay has more wifi radiation because it's larger and has a larger antennae.

    The 13" because it's not really a pro will emit lower levels and drop wifi all the time because it's not big enough to be of any danger. It should probably have been called a MB it is so weak.

    You need to sit it squarely in your lap when using it. Right over the jewels.:p

    The badboy is going nowhere near my jewels until I know it's safe. ;)

    Yup 2 years ago and STILL no conclusive proof either way. As I said, hardly reassuring. :rolleyes:

    Oh no you don't. I am under zero obligation to prove or disprove your negative assertions. You are the one making the claims of all manner of health risks. It follows that you should provide the evidence to back those claims up.

    Just because you claim the sky is falling, and no one bothers to point out to your satisfaction it isn't, does not mean you have been vindicated and are now "right".

    I read the article and am now asking others if they know whether or not, and I repeat, "couldit be risky to use the notebook for extended periods of time on your lap?"

    I've even put the key word in bold for you. :rolleyes:

    The only risk I see with using a laptop in your lab is that it might fall off or it might not work perfectly as birth control.
  19. gilkisson macrumors 65816


    No. All you are doing is slapping mud on every available surface, trying to see what will stick. OMG, maybe food wrapped in aluminum foil will cause baldness? OMG, maybe fluoride in the drinking water is a Communist plot? OMG, maybe laptops will cook me niblets? OMG, maybe the government installed a chip in my head at birth??? And so on, ad nauseum.

    Take the time to attempt to prove just one of your assertions. Study, don't panic. Think, don't knee-jerk.

    And as a final thought, I refer you to one more link which may be relevant to you or your causes.

    No. They're fine, use it on your lap. As a matter of fact, you should keep it plugged in and run a program with atleast 80% CPU usage. Assuming you believe that you may lower your chances of having offspring, I'm all for it.
    Less Shamwows to go around spreading crap on forums, the better!

    The Ivory Tower (I'm not coming down)
    More authoritative than a blog entry for sure, but peer review is hardly the ivory tower of knowledge that its defenders make it out to be.

    The OP has nothing to worry about, he's obviously so manly because he has a 15" MBP. FWIW I want a 13" matte MBP and I'd be happy (and to silence his inane assertions, I can buy a 8core Mac Pro with cash, should I so desire). My gf is happy despite me having a Thinkpad. Go figure. Actually she prefers Thinkpads, their unassuming exterior must hold a certain je ne sais quoi. But, I digress...

    The blog post has a number of basic factual errors and is poorly written.

    "Wi-Fi works through the transmission of radio waves between a router, which is connected to a telephone line, and a small transmitter in a computer."

    Lots of factual inaccuracies there.

    "Under international guidelines the amount of energy absorbed into the body from such radio waves cannot exceed two watts per kilogram when averaged over any 10 grams of tissue."

    Would be nice if they mentioned *whose* international guidelines - there are a lot - these happen to be the ICNIRP guidelines used in Europe, FCC has slightly lower. Russia has traditional had lower field strength limits, but not necessarily power density limits.

    "Alasdair Philips, the director of Powerwatch, the consumer group said that our brains and nervous systems work by using electrical signals. "

    But he forgot to mention that those signals are approximately 1 million times lower in frequency.

    "Till then children should be advised to use less mobile phones instead of frequent calls they can send text messages and instead of laptops they can be asked to use desktops mostly."

    Or they can be asked to spend less time sitting on the arses and go out and doing something more useful.

    The second article, from the Times, is slightly better - the journalist appears to at least have spoken directly to someone with a modicum of knowledge.

    my 2 cents,

    I have a migraine. I'm just not sure if it is from my 13-inch MacBook Pro or from reading this thread.

    If he got a pc you would follow him to those forums just to argue as well.
