With or without vents, it is a bad idea to block air circulation around the bottom of most devices. Heat is an enemy of electronics.

This is right. Overheating leads to bad things. Have you thought of using a cooling pad? Wal-Mart, among others, sells them for $20 USD. Ebay might even beat that. HTH, JG

I should have added that some cooling pads vent from the bottom, thus defeating your purpose. Others (my preference) vent from the rear so they can be placed on carpet, a bed, or your lap without blocking the flow of air. Best, JG

The only thing that allows netbooks to run with little to no active (fan) is the vents. Give up, you want an impossible thing... or just accept that electronics produce heat.
MSI Wind (U100) vents to the left hand side. The 'vents' on the bottom are the speakers. I put mine on the bed just on the bag that came with it, and it runs fine.

A friend has got that MSI netbook too, and I could swear that there were more slots in the bottom, other than the speakers.

But is it not possible to vent out of the side, and draw air in through the gaps in the keyboard (the other side being filled up with connectors)?

I've often thought that the bag these netbooks come in (or are available for) should have a firm side rather than soft. Then you could use it as a stand.

Quite a few of the Sony Vaio laptops are rear vented, I use mine on the floor (carpet) quite often with no problems.

It would be a bad design to draw air in through an area that needs mechanical movement and electrical switches. Dust/etc would foul it. Perhaps in through the side and out the back, but the back is often where the battery is.
Appreciate that they cram as much as they can into it to make it a small form factor.

I don't know how that one in particular is designed, but if you block primary air vents it may pull air in through areas it ought not to like connector sockets, keyboard gaps, speakers... anywhere there is a gap. Heat has a tendency to reduce overall lifespan of electronics, even if it runs ok for awhile it ought to use the vent system the designers engineered into it... which it might still, as I wrote I don't know how that one is designed.

Doesn't this defeat the whole purpose of a netbook? Light, small, easy to carry, sit it on your lap etc. If I have to carry around a cooling pad and power for it, I'd be much better off with a laptop.
It's like having a flashlight that doesn't work in the dark... Doesn't matter how whiz-bang it is if I can't use it in the dark.
It's the same way I judge linux. Doesn't matter at all if it does a better job on 90% of what I MUST do. If it can't do ALL of what I MUST do, I can't use it at all.
Products should behave the way users want. Just 'cause it's hard to do doesn't mean it shouldn't be done.

Nope, with the small size you accept the tradeoffs, if there were none then they'd all be tiny. You arbitrarily assume cooling pad and power, when it goes against reality. People use them fine but as always you need to be aware of cooling. Same with full sized laptops, if you choose to block the airflow you will have a hot running system. Not hard to do with a laptop on a bed or carpet.
>It's like having a flashlight that doesn't work in the dark... >Doesn't matter how whiz-bang it is if I can't use it in the dark.
Not at all, it's like realizing that if your flashlight isn't waterproof, you shouldn't submerge it. If your personal electronics create enough heat to need airflow, you shouldn't block that.

You choose what to buy. If you insist on starving electronics of airflow, don't buy anything that needs it.

Couple things here; 'Keyboards' on laptops are usually based on a solid plate to reduce the likelihood of liquid getting into crucial bits in case of accidental spillage. Thing two; Heat rises, hence the intake vents in the bottom. If you want to have your cooling air going *down* you're going to have to use a fairly powerful fan, reducing battery duration. -- Shaun.

It is NOT necessary to vent the bottom. I have several laptops with the cooling intake and outlet on the side. Problem solved. I'll take a fan over the requirement to hold it in the air all the time.

There's a difference between holding something in the air and simply noting where the intakes are and not blocking them (for example, putting it on a desk).
"Laptops" are, as we all know, designed to a larger form-factor than netbooks, which is why they have more latitude as to where everything is placed including the cooling subsystem.

I'm a customer. Customers don't want your whiny excuses. "Owwwwwww....It's Haarrrrd..." Customers don't care about thermodynamics. That's why there are engineers. Suck it up and design what we need!!!
This customer wants engineering to make it easy for me to use. One factor is that I can set the tiny notebook on my lap without regard for where it sits on my lap or whether There's a blanket under it. If I have to sit up at a flat table, I might as well use the desktop.
One solution is to use less power. Another is a fan. I've got several laptops with fans that hardly ever turn on. Smart engineers figure out ways to do things all the time.
If it's not a clear objective, it won't get done.
Now, quit your whinin', get back to work and engineer it!!!!
If marketing spent more time thinking about making it easy to use than whether the case is pink and endorsed by some famous person, we'd all be better off.

I hate to break it to you but no matter how they design it, someone acting childishly will find a way to make a problem out of it.
Take an automobile for example, what if someone insisted as you do that they're the customer, they should be able to block the tail-pipe if they really want to?
What if it's a washing machine, and you insist you ought to be able to block the water inlet or outlet hoses?
What if it's a pencil sharpener and you refuse to stick the pencil in the hole in the front?
A sign of an evolved person is being able to USE the technology present, not always whining about things being a problem.
>This customer wants engineering to make it easy for me to use.
Plenty of people think they are easy to use (arguably except for the whole love/hate windows and xp vs Vista deboggle).
>One factor is that I can set the tiny notebook on my lap >without regard for where it sits on my lap or whether >There's a blanket under it. If I have to sit up at a flat table, >I might as well use the desktop.
I could as easily argue that it would be more convenient if you could use a desk fan with no regard to where it's pointed, but that's not quite realistic either.
Netbooks are really close to low enough power you don't have concerns as they aren't are requiring active cooling, but then the casing tends to get even warmer than without.
Recognize there's no magical way you can just wish away the heat. If the design uses a fan there are only so many places an intake and exhaust can be placed and as soon as you move them to suit one person, another comes along and wanted the USB or the audio jacks or something else where it was moved. Plus, these days it's generally true that the intake and exhaust need be near the same region because you have a squirrel cage fan blowing through a thin finned 'sink on the same subassembly.
When a laptop is large enough the battery can go on the bottom layer or further inward this is easily accomplished out the back, but on the sides with today's widescreen formats (which I dislike for typical computer use vs watching video, but they do compliment the shape of a keyboard when the netbook is closed to smallest size possible) there is more limit.
As soon as you think it shouldn't vent out the bottom, someone will want to cradle it in their lap in a way the blocks the sides and leaves the bottom open. Problem is, all the changes in direction of airflow come with a penalty. If you want your netbook to be larger and/or louder for the sake of the exhaust port location instead of other attributes then you seem to be in a minority since I've read quite a few articles and reader comments, none of which deal with dissatisfaction about where the exhaust port is.
>One solution is to use less power.
Is it a solution or is it taking a slow system and putting it below the threshold for usability with the world dominant OS most people will want to use, since there's no magic way to continually use less and less power until the tech allows for it. Just be thankful you have the options you do, many doubted whether Intel was interested in making Atom CPUs since they seemed likely to, and certainly have, undercut their Celeron sales volumes.
>Another is a fan. >I've got several laptops with fans that hardly ever turn on.
Sure, bigger form-factor allows for larger heatsink, lower thermal density.
Which gets hotter, a pot of water with 1W applied to it, or a thimble-full?
>Smart engineers figure out ways to do things all the time.
The smart engineers have used their smarts to make what you see in the market, but even then there are cost constraints to make it a marketable item.

It's not half the problem you're making it out to be. Everyday items all around you have their own requirements for use and you learn how... just that simple.

It's not too unreasonable to wish that a laptop would work in its normal position on a variety of surfaces without overheating.
>A sign of an evolved person is being able to USE the >technology present, not always whining about things being a >problem.
This is Usenet, a place for whining. And of course a place for those who whine about alleged whiners... ;)
>If the design uses a fan there are only so many >places an intake and exhaust can be placed
Both my netbooks (equipped with fans) have a case design that thins in the front where the air intake grills are. That puts the intakes while still on the bottom above any surface the netbook sits on. (The output grill is in back on one and the side on the other.) So I can put them on any surface (lap or blanket) with little worry about heating problems.
So this is one design that passes the 'variety of surfaces' test. I imagine this and similar designs could be ported to larger laptops if MFGs had an incentive to do so. Maybe if enough people whined... ;)
