HP Envy 15 Heating Problem

bruce20 · Apr 27, 2014

Hi Guys,

Hope you're great.

My Specs are:

HP Envy 15 J138tx

Ci7 4700MQ 2.4GHz
1TB Hard Drive + 24GB SSD
8GB DDR3 1600MHz Ram
2GB Dedicated Graphics card 740M
Windows 8.1 64bit

I bought this new laptop about 3 weeks ago. It was cool in the beginning even after 8 hours of non-stop use, however now I'm starting to feel it heats up a bit, I mean not too much, but definitely now its hotter than what it used to be right out of the box. Now it gets hot even after couple of hours of use. And its as hot as my old HP G6 Pavilion used to be.

Its new so no dust has clogged the vents. I use it on a hardwood table, so vents are not blocked. Fan is not running like crazy and I'm not running too much apps & its still hot. CPU usage is about 5% and Ram usage is about 60% and system seems to be running smoothly. And even the "Hp Cool Sense" is ON. Then I don't understand why its getting hot? I've read some threads on internet saying, YES HP Envy DO have this heating problem, which HP considers is normal.

What you guys think? Is this NORMAL?

Thanks.

Any laptop with discrete graphics pushes the thermal capacity of the heat sinks much higher. Turning of that hot-hot GPU should help. Does your laptop have options to configure Optimus or are you forced to stay with the discrete (740m)? It should look something like "Force Power-Saving GPU" under NVIDIA control panel or Windows power options > Change advanced settings.

ttjambe :

Isn't it supposed to switch automatically between the on-board graphics & dedicated graphics card depending on the requirements? I've checked, but I can't find any relevant settings that you mentioned.

Also, when I check in Desktop > Screen Resolution > Advanced Settings, I see the on board graphics card Intel HD 4600 is active.

It switches based on the configured power plan. When the laptop is on power saver it should force the integrated on and the discrete off. If there are options missing then the driver may be out of date or corrupted. Update the graphics driver from HP's website.

I just found the option under Set Physx Configuration. Its set to Auto-Select (Recommended). If its set to auto, then doesn't it mean on normal usage like browsing/skype/ms office it will use Intel HD 4600 & not the dedicated one? And doesn't it mean then heat is not being caused by dedicated graphics card, since its not being used?

It depends. The two primary sources of heat are the processor and the GPU. The PSU technically is there as well but in a laptop it is an external power brick. The haswell i7s are designed to be powerful but efficient, which is why you can even have them paired with a dedicated GPU in a laptop anyways. Lower the maximum state of the process will result in a noticeable decrease in performance.
If you are plugged in the Auto-Select feature will automatically try to maximize performance if high performance is enabled by using the GPU for everything. On battery it will be more conservative and only enable the discrete for games it detects. You should't get heat problems on battery because it would drain the battery and that's horrible engineering.
