Laptop Help

[Knightmare]

I'm trying to work on my friend's laptop, but whenever it overheats/uses the cpu 100%, it sends itself into sleep mode. I have sleeping/hibernating disabled in the power options, but it still goes to sleep. How can I stop this from happening? Also any home remedy suggestions on how to keep the computer from overheating are welcome. ;)

Shutting down when over heating is normal to prevent damage. Get a base with a fan in it to use under the laptop.

Also might check to see if the fan is working on it or if there is dust blocking air flow.

It sounds like the fan is working. What else can be done to ensure it's working?

[Sonar]

start it up in safemode? just to rule out a program causing the shutdown?

[rudrax]

When a CPU overheats, individual components inside the CPU starts shutting down. Hence, the amount of the available resources inside the CPU gets decreased for what CPU uses goes high. When it reaches the point, about 80-90 degree celcius in laptops, laptops hardware level safety mechanism shuts it down which is independent of the OS' setting.

If your laptop is overheating, you should not use your laptop unless you get it fixed. It's dangerous to use an overheating laptop.

If the overheating issue is not caused by hardware malfuction of sofware issue, you can open the casing of your laptop (if exceeded warranty period), ditach all the components like, ODD, HDD, RAM, CPU and fan. Clean all the dust from them, check the air intake and outlet vents of the casing if they are blocked with dust. Then if your fan's propeller disc is packed inside a closed box like structure, then open it an clean the dust inside it and the outlet vent of fan. After that wipe out the thermal paste applied in the CPU, GPU, and Chipset and apply new one carefully. Pack 'em all and start your laptop.

ok, just a wild guess: is it an HP Pavillion (Compaq) DV6?

if so, there's no workaround for the overheating, short of disassembling it, putting on decent desktop heat sinks and using it like that.

actually there is something that can keep the heat down but at the cost of performance being similar to a 2002 celeron.

open up power settings if you're using Vista or 7 (AND YOU SHOULD!) and set the maximum proccessor speed to 81% this will prevent it to enter the last (and hottest) power stage.

if the issue persist then lower the maximum usage to 51% which disables the second to last stage as well. but at this point you should be considering either replacing the heat pipes assembly or getting rid of the whole thing and buying a laptop with a decent heat exchanging system.

Absolutely correct - it is full of dust and grease, it is inside of the computer, including the fan blades - a mixture of grease and dust - it is like plaster.

Tell, what is the temperature before the "hibernation process" begins?

Disassemble the laptop to clean up the fan (using the blower - not suction feature) - especially the ventilation outlets (also known as vents.)

Check out the heat sink and apply fresh thermal paste, if required.

I don't really feel comfortable taking the laptop apart. I would if it were mine, but since it belongs to my friend, I would rather if they paid someone to do that.

I think I might give this a try. I'm not sure what the laptop is. I know it's an HP Pavillion, but I don't think it's a Compaq.

Doesn't matter, how you do that - paid or unpaid, the important thing is that it needs to be cleaned.

could be a malware @work, anybody thought that running in background :think:

limit your CPU usage to 95% from power options and run only a single program at a time

if still you face overheating, maybe check for virus.

If it's clean.

then follow the suggestions above :P

:guns:

@ Kalju

Hope Knightmare is not having a worse nightmare than the one suggested by the vital statistics on your screenshot.

UPDATE: I couldn't sleep last night, so I decided to run ESET to see if something were missed. I set the cpu max performance to 81% and ran the scan in safe mode. The computer turned off about half way through the scan. I'm thinking I may just breakdown and dust it out.

I am having the same computer and the same problem.I did all I could do but the vendor said that this PC has the problem of overheating .I has also submitted my problem at nsane forum solution. lastly I got a cooling pad ie a big sized fan below the laptop and all is not that good but now I can work on my PC for hours without it going into sleep mode

[H4rDw4rE]

Like in previous messages you should observe what temperature of your laptop (mostly cpu and vga) is.

Almost sure that it is far beyond 80 degrees celsius (in few minutes after power on).

Cleaning cooling fan and heatsink is mandatory in this case.

After that you should change thermal paste as well (it is mandatory also).

Then you should check what process use cpu (take a look for that ones which uses much cpu power) and post it here to see is there some suspicious process.

Get decent cooling fan is good thing and in the end if it is HP laptop then you should get used to it (they tend to have shutting down most often...).

Don't think you can damage it in short terms but in long run you definitely will make problems if you are decide to use it in that condition because most of the components on mainboard (capacitors) can't withstand high temperatures.

So advice is to stop using it until you fix it.

I am having the same computer and the same problem.I did all I could do but the vendor said that this PC has the problem of overheating .

That is a feeble excuse - generally, offered by small-time distributors who:--

• do not believe in customer service or
• are incapable or
• both of the above

lastly I got a cooling pad ie a big sized fan below the laptop and all is not that good but now I can work on my PC for hours without it going into sleep mode

The cooling pad is just a workaround - not a solution (enjoy the temporary bliss - while it lasts.)

It is like bolting the stable gates after the ass (horse) has bolted (pun intended.)

[VileTouch]

I know it's an HP Pavillion, but I don't think it's a Compaq.

Compaq IS HP. thing is Compaq designed (or rather ordered) this mess and when HP took over they never really changed anything, other than the logos, so the consumers got shafted. and to this day they refuse to fix it.

here. let me show you what the problem is:

see? it's not virus or dust or anything like that, it's as simple as that they decided to put both the proccessor AND the gpu on a single heatpipe in order to save a few pennies.

this means that no matter how much you clean it, this one heatpipe CANNOT transfer that much heat. there's no way around it really.

[Knightmare]

Would a temporary fix be to put my friend's HDD in my laptop? I would think that would allow me to run the necessary scans.

It's reasonable and logical since the laptop fan blows air outwards.

The holes increases the airflow in the heatpipe.

I have performed this procedure on on laptop, extending its life to 6 months - does not work on a few hardware, though.

Those were not mine. I saw it on youtube and took pictures of it since I want to try it too. :)

hmm... that's interesting, the TG-2 is not adhesive though, so i would expect the little heat sinks to slide off within a week.

edit: arctic silver does have a thermal adhesive but it's not exactly cheap given the context
