Can a laptop runs 18 hrs non-stop?

I just own for now a pc desktop....and planning to buy soon a laptop pc for mobility. Maybe, laptop could be the only pc I have but I was then wonderin if laptop can run straight 15-18hrs non-stop if plug into electrical outlet without any problem of overheating or something like that....

 

I have been using a Dell Inspiron laptop for 2 years and I have often left it on (running on AC power) for long durations and never had any problems. Btw, the Inspiron's power-management blacks-out the display and 'throttles' the disk-drive after the laptop has been idle for about an hour or so (and much sooner when it's on battery power)!

 

U can do it same via windows builtin Power OPtions in Control Panel.

 

Yeah, definitely depends. I left my laptop on for a whole month.

 

IMO, it's directly related to the amount of CPU processing one does. At idle, I think most any laptop could be powered up and run a very long time. But raise the CPU activity to a fairly constant level (which would vary based on cooling capacity) and you may be heading toward a problem. Certainly, adding one of those USB fan cooling bases would help...

 

I have my laptop on for a few days on end. I'm to lazy to turn it off at times plus I run use torrents.

 

Burn out the motherboard ...well, that's what I am worried about coz this thing looks so small and very compressed inside u know what I mean. What's the brand of ur laptop, maybe, its an older model?

What do u mean of fan system to blow air under it ...is that mean, installing additional fan system into the laptop pc....or just an ordinary electric fan blowing air under the table?

I was even thinking of using or getting a wide size tile used on tile flooring to put on under the laptop so that over-heating will be avoided...u know...clay tiles for flooring absorbs heat and it is always cold. What do u think bout thiz ...anyone tried thiz??/

 

you can get little fan trays made for laptops that you place under them and in most cases plug it in to usb to power the fans.

I have a dell inspiron 6400 which i've left running for days on end with no problems at all, it seems to run very cool imo. Its not super high spec but its good enough for my needs.

 

Hello,
I got a Dell Latitude 420 at work that I leave on for weeks, without any problems - it seems... So far so good.

A P4 isn't a mobile processor It puts great stress in the VRM and the cooling areas.
Laptops with the Centrino logo or powered by AMD Turion processors run cooler and they're way more reliable.

 

I have a resource hogging Toshiba laptop that runs about 12 hours a day, sometimes a few days straight. As long as I blow it out with an air can every few months to keep the fans clean it doesn't have any problems. Mine is always in an air conditioned room though.

 

Used to leave my T21 on 24/7 with the original P IIIm 850 Mhz processor. This is while it was mounted in it`s docking station which elevates the back of it where the processor and its cooling vent are several inches off of the surface. I have since upgraded it to a P IIIm 1Ghz using Artic Silver paste when installing the upgrade. As long as it is elevated, or at least the side with the processor is not setting flat on any surface it is fine left on for prolonged periods of time.
As stated above, if the lap top you choose does have a processor designed for mobile use you should be fine. They have made improvements in mobile technology = cooling. The addition of the before mentioned cooling trays are not a bad idea either, a little extra insurance never hurts. Plan on one myself.

 

I'd guess that that burnt out of the mobo wouldn't have happened at that time.

 

I bought a Dell Inspirion E1705 last April and its been on ever since.
Guess I should look into one of those platforms w/ a fan eh?

I've never used one of those fans and i live in the desert where temp can get over 40C and my DELL has run sweet.

 

Yeah, I did a review search after reading this thread. They appear to be useless...

Thanks!

Would love a link to the reviews. Have considered one myself, some come with extra USB ports which are handy in themselves. IMO anything that circulates more air around the heat producing areas of a lap top would\should be helpful. Would love to read the other opinion(s). Not doubting you, would just like to see their results.

 

To be quite honest, not all the reviews I read were bad. There just weren't enough good ones to temp me to go to my hip

Thank you Screamer & Peter2150. My Thinkpad has a single outlet to the rear on the left side (as I am facing the keyboard) which blows out. Next to it is my plug-in wireless G card, next to it is the hdd. The whole underside on the left can become quit warm to the touch if left setting flat and being used. There are really no venting inlets to be found. They must count on the fact of the case not being air tight.
Sweater, sorry for sort of stealing your thread. My suggestion to you from all this are several fold. Get a lap top that has a processor designed for mobile use. A couple of processor types have been mentioned. Shop carefully and compare. Be aware of where and how the fan(s) vents, side, bottom or back. Does it draw air in or exhaust it. Try when using it to not have it setting flat on any surface as this will potentially limit air circulation. If you still feel a cooling pad is a good idea then with the knowledge you have of your lap top and how it is meant to cool you will be able to make a much better decision on which one to purchase.
