question about cooling of laptops

By DanLM ·
Recently I bought a lanovo laptop so that my girlfriend could have a pc when she is here. Because she isn't here all the time, and I just can't get use to using a laptop it was siting idle I installed the grid computing application on it. I am hugely into the grid computing with regard to Seti and the Einstein projects, and the laptop is crunching decent numbers. It's only a dual 1.6, but it's idle so it is crunching numbers 24/7.

With all the news that was in the paper last year about laptops starting on fire, I'm worried about this one. This is running on house current and not battery. I know, obvious because it is on 24/7.

My question is, should I be concerned about this over heating? I have checked it, and it doesn't seem hot. But I would go out and buy an adapter/stand that would cool the laptop if this is an issue.
Actually, does anyone see any harm in running a laptop 24/7???

I know, dumb questions... But I really don't want to fry this laptop.

Not dumb really

by The Scummy One In reply to question about cooling of ...

But there was a lot of hype about the fires from notebooks, especially after the video hit the Internet.
In reality, I beleive the # was 7 worldwide caught fire or some # like that. A very, very low percentile, and several were traced back to batteries being inserted improperly or being of faulty make. These were mostly corrected last year with recalls from just about every manufacturer on batteries for certain model systems.

However, keeping it a little cooler will do nothing if the unit is defective. If it were to cause a fire, it would heat up very, very fast internally. Even extra fans would not prevent it.

But, heat in general on a notebook or any other computer is a bad thing. For around $20-$40 you can pick up a docking tray wich blows air onto the bottom of the unit. While many newer model notebooks have the vents on the side, not the bottom, I suspect that most of these are just a 'feel good' item.

If there is a vent on bottom that is not exhaust though, these can cool systems down pretty well.

Basically though, if there is an option in the BIOS to keep fans on while on AC power, this is a recommended option. Keeping it in a cooler place is also recommended.

bloody lanova

by DanLM In reply to Not dumb really

I tried to get into the bios last night after I read your post, it's a lanova... Press lanova button for detailed boot instructions. No delete, no f4/f5.

It was late, so I just let it reboot. I'll look at that again later.

There is 2 vents on this. One on the side, and one on the bottom. The side seems to be the hotest point... But, nothing that is painfull. Considering this has ran for a coupl weeks now 24/7. I consider that a good sign, but I mentioned below. I would like to provide a bit more ventalation I think just to be on the safe side.

Lenovo

F1 for BIOS, also like norm said if you are just running on house current leave the battery out.

Only downside is that if power fails the laptop is going down.

Couple of thoughts...

by Inky960 In reply to question about cooling of ...

Dan, maybe this show what a fink I am, but my first thought was, since you only recently bought the Lenovo, crunch away! If it fries, let the warranty cover it and act accordingly next time. Hehe--or not, it's up to you. // I had a laptop last year that ran so hot (an AMD 64 Turion) it was actually painful to touch, and I bought a Targus Coolpad ($25 @ Wal Mart), which kept it nice and cool. If you're holding the computer in your lap however, the CoolPad makes it cumbersome - a lot of sliding around, double thickness, more weight, etc., but I had to use it that way. // It seems to me that if you have the Lenovo on a flat, solid surface (a table, desk), then it should get plenty of air and should keep itself cool. I'd go for it.

It does sit on a flat surface

by DanLM In reply to Couple of thoughts...

I was thinking of just getting something that lifted the laptop a bit off the surface to provide better circulation. I was hopeing something as simple as that would help it stay cool.

Another thought.

by normhaga In reply to question about cooling of ...

Last night I was doing some research on lithium batteries. Heat destroys them. They are also the cause of concern regarding fires in you question. Based on the information I gathered, I would suggest that you first discharge the battery to about 40 percent and remove it from the computer.

Removing the battery during AC operation also helps the cooling of the NB.

Never thought about that

I have priced batteries... Suckers are expensive.

Thanks

I use a laptop

by Tig2 In reply to question about cooling of ...

And I rarely shut it down. I use a MacBook but have had both Dell and HP in the past.

Because the MacBook is UNIX, I leave it on and have some tasks that it manages when I am not using it. And then it goes back to sleep. I reboot every couple of weeks or so- but rarely turn it off.

I manage heat by using a bakers cooling rack. This is a wire device that raises the machine about an inch from the surface of the desk. Because it is a wide metal mesh, it allows air to circulate around the device completely with no hot spots.

You can find any number of fan based pads that will assist in cooling but so far, my low tech solution has been my favorite. I paid $5 for a pair of them and they easily accommodate a 17" laptop. Best of all, they require no power whatsoever and are easy to transport with the machine.

I use the rack as a preventative. The SO's Vaio began breaking down due to heat even though it wasn't physically too warm. The rack was an easy and inexpensive preventative measure.

Beleive it or not

by DanLM In reply to I use a laptop

I knew exactly what you meant by the bakers cooling rack.

I went out today and bought something that has a fan to pull the heat down, but if couldn't have easily found something. I was going to stop at KMART and buy a small cooling rack like you sugested.

When I can pick up another UPS, I will pull the battery like everyone has sugested. I already run individual UPS's on each of my other machines.... That corner of the room only has a good power surge on it. But, that corner is the TV corner and it needs a UPS also.

Thanks everyone, I have been racking up some serious numbers in the grid computing.
