I recently purchased HP Envy 15 Touch smart. I realized that when keep the laptop on the bed or pillow, It gets terrible hot. Today I measured the temperature which reached 82 degrees on the bed. Is my CPU throttling?

Is it normal for a laptop, where CPU gets that hot? I hope my CPU didn't start degrading because of this temperature
 
Doubtful it'd degrade, more from voltages if they were too high. You could definitely get enough heat buildup though to hurt drives and the motherboard parts of that nature. Doubtful it'd be throttling there either.
 
I don't think my CPU has been under 82C in two years...lol
 
Which CPU is it? I see HP Envy 15" Touchsmart laptops with either Intel or AMD CPUs.

Most Intel CPUs, including some of the ones that appear in your laptop, have a maximum temperature of 100C, at which point they throttle and/or shut down to prevent damage to the CPU. I am less familiiar with how AMD CPUs handle high temperatures but I'd think it would be similar.

Then don't do that. Almost any laptop will get really hot when you do that. That's what blankets are supposed to do.

You really should avoid keeping your laptop in bed, pieces of lint may be sucked in by the fan and will block airflow to the CPU, causing the laptop to overheat. For bedtime, it's best to stick to fanless devices like tablets or phones.

Agreed.....I'm wondering how many peeps like this guy then pawn these laptops off on here as "mint and working"? :rolleyes: Gotten a few used ones on here that have died rather quick...

I think that's a bit extreme to accuse the OP of planning to defraud someone based on a simple post in which he asked for some reassurance that he wasn't putting his equipment in danger there Shuttle:rolleyes:..

OP, if you have an Intel cpu (which I am 99% sure you do since AMD cpu's will throttle/shutdown in the 60-65C range) then you are fine. Like others have suggested, don't use the notebook in bed unless you are using a portable desk of some sort, like this one. I purchased something like this for my mom since she uses her HP in the bed a lot, and she raves about how great it is all the time!
 
cool, your response to Patriot in that thread is eagerly awaited, cheers

Haswell core i7 4700MQ. I thought Haswell desgned for mobiles are low power and excellent in heat management

Yes, they are. The fact that it only hit 82C and continued to run when the heat vents were completely blocked by your blankets is testimonial to that. Now, seriously, stop doing that.
 
I agree with everyone in here,never set your laptop on soft surfaces that will impede airflow.

I let my little sister use one of my old laptops and she was constantly leaving it on her bed running playing music and watching videos while doing what ever else she did,I told her countless times that she was gonna kill it by doing that,and one day it finally died.

When I took the it apart one of the chips on the board pulled out with the heatsink completely separated at the solder connections.
 
I have stopped putting it on bed or pillow. I love my new laptop, therefore don't want the CPU to start degrading by getting hot. So what is the suggestion? Should I got a good laptop stand that consists of a fans which take power from USB?

You could, but unless they've gotten better in the past 5 years I've found them to be mostly a joke. Laptops are going to get hot no matter what you do. They are built in such a way its damn near impossible not to get them warm doing small, stupid tasks. The best thing you can do is get some elevation from the bottom to a hard surface. If that's not possible than a stand with fans that sits directly on the bottom should do just fine. One thing great about buying a gaming laptop 5 years ago was they built the exhaust on the sides. I wish more could do that.

Something like this? I've already ordered one;)
 
That CPU has a TDP of 47W. Basically anything above 5W cannot be cooled passively for an extended time, which you basically do if you block the airflow.
 
I picked up a laptop cart for my mom a few years back. She uses it all the time still. I think she liked it because when she's ready to sleep, she didn't have to get out of bed to put it out of the way. Not so great to use all around the house, but just for a solution for the bedroom, it's ok.

I got it at office depot, but here's a link to a similar one.

I've got an old dell inspiron laptop that i've had for years now. I loaned it to my nephew once to use for school. He brought it back 2 weeks later and complained it was broken because it kept shutting off on him. After talking to him for a bit, I figured out he was setting in the bed using the laptop on his lap, on top of the cover because "it heats up and keeps me warm"...... So basically he was overheating it and causing it to shut off. He never was a smart fellow. I guess I was lucky that it didn't hurt the laptop, it's still running strong all these years later. I still use it to this day for my vinyl cutting machine.

Actually, just by replacing the stock crap thermal compound with some not so crappy stuff, will generally drop 10-15c off of load temps on a Dell laptop.

Put some AC5 or IC7, and you can drop a few more degrees.

This is with proper airflow though.

You would think that the OEMs would start using some different compound that actualyl works, but they have not changed in the last 13-15 years at least. They have been using the same craptastic grey junk that starts separating after a not very long period of time. This leads to hot spots on the processors which will not usually trigger the temp alarms or shutdown, but will cause all kinds of stability problems.

I used to do onsite Dell warranty repair. A lot of the P4 desktops and laptops would have overheating processor problems.

One of the main fixes I did was to replace the thermal compound with non-Dell stuff.

I actually did some load testing on an old Dell XPS laptop that had a desktop P4 in it. Just changing the thermal compound from the super craptastic grey junk to some cheapo white thermal compound dropped the load temps by over 10c.

I would love to apply AS5 thermal paste, as far as I don't mess up with the warranty by opening the whole circuit
 
Get a food tray if you want to use your laptop on the bed. Something like mcdonalds style.

That thing literally caused a shock, until I stopped placing it on the bed or pillow. Even now as you can it is on the table, and under the air conditioner the temperature touches 62 degree when I am not playing any game.

That's completely fine. On a table my i5 3317 idles at around 40 and goes up to 60 in non gaming tasks in my Zenbook Prime UX31A.

IMHO, a 47W TDP CPU doesn't belong in a laptop, especially one as thin as the HP Envy. Darn shame to, its otherwise a nice system.

I'd look into limiting the CPU clockspeed/multiplier while using it for less intensive tasks.
 
My i5-2520M (T520) has spent hundreds and hundreds of hours at > 80C compiling kernels.

I wouldn't worry about it.
