Re: shutting down PB and heat

I use the Traveler' Coolpad and it works very well and is extremely
portable, so you can take it with you in your laptop case.

My wife and I use Podium CoolPads for our respective Books (an icebook and a
Wallstreet, both of which can get pretty hot). I highly recommend them (and
no, I'm not a shareholder). Info is here:

Definitely not silly, it's a good idea. But I thought I'd add my personal
experience with a PowerBook stand, the iCurve in my case, which I found
effective for increasing air circulation.

Here in fire-ravaged Kelowna over the summer, temperatures in my office
reached +100 for weeks. As long as my Pismo was on the stand, it was fine,
fan came on once in a while. If I set the Pismo down on a flat surface, the
fan came on after a few minutes of use.

As well, the stands have the added benefit of raising the screen to eye
level.

I've got to disagree a little here. The fan is on for a reason, because the
PowerBook is excessively hot. Shutting it down is the last thing I would do.

As in a car, the Powerbook will cool faster if you leave it running with the
fan on. Just stop working with it and the amount of heat generated will be
negligible, allowing the fan to do its job that much quicker.

And of course, when the 'Book is in deep sleep, the amount of heat generated
is almost nil.

Re: shutting down PB and heat

[Brandy]

The Lombard (Bronze) is the only book I have owned the blew from heat, 
it blew twice, after repairs I got in the habit of shutting it down if I 
was not going to use it for extended period of time, currently it's shut 
down and sitting on my office shelf since I prefer my TI.  It still 
fires up with no problems and will find a new home with my brother 
in-law. Nary a problem with any book aside from the 2400 trying to defy 
gravity, never did get a GLOD on that one, unless you define that as 
Great Leap of Death! ;-)

What I should have added is that, yes, it is true that heat can cause 
damage to your PowerBook in the long term.  Heating and cooling the 
PowerBook causes expansion and contraction of all the components. 
Some materials expand more than others when heated.  This can cause 
problems with things like solder joints or other contact points on 
the logic board.  Over time, cracks may develop or the contacts may 
drift apart...

The truth of the matter, though, is that unless your PowerBook is 
excessively hot (hot enough to melt either the plastics, insulators, 
or CPU itself), the damage caused by normal heat is negligible when 
compared to the mechanical damage caused by carting the PowerBook 
around and when handling it.

Your PowerBook is much more likely to die from the mechanical 
stresses of everyday use than it is likely to die from thermal 
damage.  If it were just thermal problems, your PowerBook would 
probably run for decades...

Peace,
Drew

Nothing.

Shutting it down can't hurt, but you don't necessarily _need_ to shut 
it down.  These 'Books may feel hot, but they're probably still 
within the operating range that Apple engineered for them.  I've 
never actually heard of a PowerBook overheating because of normal use.

Now, if you block all the ventilation ports, sit your PowerBook on an 
electric heating pad, and use it on the hottest day in July, THEN I 
might worry...

That fan coming on is perfectly normal.  My advice is to just ignore 
the fan noise (unless it seems excessive - like it has been running 
for hours).

Or just do whatever you are comfortable doing.  You aren't going to 
make things worse by erring on the side of caution!

Peace,
Drew

Well said... :-)

It can't _hurt_ to shut down your 'Book when it gets hot.  That noise 
you hear probably _is_ the fan.  It comes on only when the PowerBook 
heats up enough to trigger it.

I'd say the jury's out on the long-term impact of that much heat, but 
in the short term a little heat probably won't hurt your Lombard. 
After a while (several minutes to an hour, depending on conditions), 
the fan should cool down the innards enough to allow it to spin back 
down.

In the summers (New England, Arizona, and Colorado), my Wallstreet 
gets pretty darn hot (especially if a CD is in).  It gets so hot, in 
fact, that the fan runs constantly when I use it on my lap (and if 
I'm not careful, it'll leave sweat marks on my pants!).

But that's better than owning a Dell.  A while ago, a Dell owner 
apparently got blisters on his genitals because the laptop was too 
hot.  Heh...  The Register ran a story about that in November last 
year .  Of 
course, it also makes a slight comment about Mac users and "objectum 
sexuality."  Hmm...

Peace,
Drew
