Laptop Fan Constantly Runs & Gets Really HOT!

 
0
 

hello. i was wondering if anyone could help me figure out why my laptop fan runs nonstop after startup. it usually takes a few minutes after starting it up, and then it continously runs until i get irritated and shut it down. also, the bottom of my laptop gets VERY hot. to the point where i cant even touch it, and i am scared to leave it on because it gets SOO hot! the keys also get pretty hot, but no where near as hot as the bottom of the laptop. its only a year old, so i dont know what could be wrong with it. i havent even really used it but a handful of times in the past several months and thats because it gets too hot and i dont know whats wrong with the fan.

i just downloaded hijack this, if anyone can help me out, i will post the log.

thankyou sooo much in advance!!!! --- danielle

well, the fan is running because the cpu or something else is getting really really hot. the fan is not your problem, it's trying to do it's job. what kind of laptop? what cpu? os?

Hello, As the first reply said, the fans are trying to cool the CPU. You have to have good airflow to get good cooling. Here are some checks thoughts:
1) Are you sitting the laptop on a soft surface that can block the cooling ports? blanket, table with a table cloth, bed, lap?
2) Is the cooling areas blocked with dust? Use compressed air to blow all the ports, fins, crevices out. If you can figure out the air flow, blow the dust out in the opposite direction.
3) Try one of those laptop cooling pads.
4) You may have more then one fan inside and one is not working.

i have a emachines [gateway supported] model# mx4625. the os is windows xp. when i alt-control-delete; sometimes it shows my cpu as 100% and then rapidly jumps down to 0% and then goes up to like 2%.

i usually have it sitting on my bed, or on my lap. what brand cooling pad would you recommend?? i figure i could start with trying a cool pad, because i am not sure how to check to see if the cooling areas are blocked with dust. thankyou soo much for both of your responses =] -danielle

doesn't mean its not getting hot just because its not overloaded ,can of compressed air ,blow out the fan /heatsinc from the outside best you can ,might help i have laptop here that gets so hot the video goes crazy,blaptop freezes but its neither the fan bot the cpu ,so there is other things that cause heat buildup also

thankyou caperjack. so i should just try and can of compressed air, and hopefully that helps!! i will pick up a can, and let you know how that goes!! thankyouuuu!!!

okay, i have another question.. i'm not sure if you know anything about adding memory cards. but i wanted to add some more memory to my laptop.. this is what the gateway website said about the memory on my specific laptop.. my question is how much more can i add, and what kind? brand? all that good stuff.

512 MB DDR (1 × 512 MB) SODIMM (PC2700)
Expandable to 2 GB
Total: 2 DDR Slots | Available: 1 DDR Slot

would this memory work?

my experience with laptops would say yes it would work ,and from you other post it looks like you have two slots to install ram and it will take 2 sticks so you could remove the ones you have and install 2, 1 gb sticks for a total of 2gb

try the cool pad too, i have one for my laptop. it's an antec ($20 best buy) and it works fine. you can find cool pads anywhere laptops are sold.

i was just looking at the antec cooling pads on the bestbuy.com website, and theyre are a couple that come up when i search antec. and they look totally different from one another. which one would you recommend? or a link to any website would be totally awesome, if and when you have a spare minute of course. =]

and thankyou again!!!!! -danielle

i wish i had this one

http://www.newegg.com/Product/Product.aspx?Item=N82E16834999362

i've seen it at fry's, it's very well made. but if you have any jacks on the front of your computer it will cover them up.

here is a great one from belkin

http://www.newegg.com/Product/Product.aspx?Item=N82E16834998314

it's much better for use on your lap and seems to be very effective.

My HP G60 got up to 212f without shutting down.

It really pisses me off, it starts running like crap...

Who makes a laptop you have to keep on a flat surface anyway? "Laptop" not table without cloth top...

HP G60 - I hate it

Some laptops use a heatsink with a liquid inside of a hollow tube that helps to transfer the heat away from the CPU. If the tube springs a leak, the liquid will evaporate out and there will be reduced efficiency of the heatsink to take the heat away from the CPU, and the fans will run constantly and the laptop will feel quite hot. An overheating problem cause by this type of failure is sometimes difficult to find because the heatsink and everything looks fine, and all of the parts work fine when installed into another computer. It could be that the actual heatsink itself has lost its cooling liquid and is not efficiently removing heat from the CPU anymore.
