Enhanced sensor monitoring on HP Envy

I'd like to enhance the sensor monitoring on HP Envy series in HWiNFO32, but need a bit of help from owners.
Let me know who is willing to supply information to me, so I can analyse it and implement better monitoring (and many fan control too if possible).
I need the following information:
- HWiNFO32 Report and Debug (HWiNFO32.DBG) files with Sensor data
- RW-Tool dumps: EC and ACPI/DSDT

I have a bit of help directly from the manufacturer's engineers, so I think it might be possible

 

2shared - download ENVY-PC.HTM

HWiNFO32 Report

You probably don't have everything you need? Just don't realy know exactly where to find it.
Can you say what might be possible? Like changing voltages, RPM fanspeed or other stuff.


Note: This is the 1st gen envy.

 

You need to download the RW-Everything tool from:
RW - Read & Write
then run it, click the EC button, save the data and send.

 

not sure if this is what you need from hwmonitor, but I did the RW stuff too (it's all in the zip file)

envy stuff.zip

 

Thanks for the data. The RW dump is exactly what I wanted, however I was asking for HWiNFO32 Report+Debug File (not HWMonitor )

 

well it had hw in it.

do you still need the hwinfo32 stuff, I'll download it (tell me what to do to get the stuff from it. ya know what do I do to go grab the report and debug file. just make a report and look for the debug file wherever it ended up at?)

 

Something like that
The Debug Mode is described here too:
HWiNFO and HWiNFO32 Forum • View topic - Read this before submitting a report

 

alright. I see how to run it.

uploaded. HWiNFO32.zip

This is from a gen 1 envy 14 (CTO-1000) with an i5 520m and the radeon 5650 mobility gpu active.

 

Thanks for the data.. I currently have enhanced support of the Envy 17 series and it seems Envy 14 is not compatible with that. I'll check more if it's possible to enahnce the support for 14 too.

 

Could you please run the RW-Tool again, press ACPI, then select DSDT and attach that dump?

 

So here's a new build to support the HP Envy 17, Pavilion dv6 and dv7 (Intel only) EC sensors:
HWiNFO32 v3.60-973
A new sensor should appear with some temperatures and a fan speed.
Please provide feedback how it works...
I'm continuing to work on the Envy 14...

 

DSDT.rw

there ya go

 

I just downloaded this and it works (ENVY 17), I can see the fan speed appart from all other temperatures. I can provide data, if you tell me how.

But I have a questions, is it possible to control the speed of the fan?

 

Please post a screenshot of the Sensors. Would be also interesting to see the values in idle and under load if it works properly.
Currently there's no fan control, but I might try to implement it later (if possible at all).

 

What about the envy 15?

 

These are the idle values.
As for the fan speed, I would be very interested in that.

 

No idea yet, but might use entirely different method. Can you submit the data gathered via RW-Tool: EC and ACPI/DSDT dump ?

 

Nice App. I lost the ability to monitor GPU temp using HWMonitor after going to bios F.13. I had to run GPUZ at the same time.

Thanks,

Dave

 

I experienced some ACPI issues with the 973 build. With the latest prerelease, I experienced some intermittent switching from A/C to battery even though the power adapter was plugged in, some system freezing, sometimes the dvd drive woulld end up in an ejection loop until a cold boot, and even the fan spinning up and not spinning down until a cold boot.

I posted it on the bug report section of the HWiNFO forum.

With the latest stable build, I have none of these problems. Once I switch the the pre-release, I can replicate all the issues over and over again.

 

Seems to be a conflict between HWiNFO32 and some component communicating with the EC too. Will continue on the HWiNFO32 forum..

 

I just implemented the sensor monitoring on Envy15, so here's the new build to test:
HWiNFO32 v3.60-988
Please let me know how it works..

 

Thanks, will try it when i'm home.

 

It doesn't work?

 

Hi Mumak,

Have you managed to implement fan speed control for the ENVY 17?

 

Seems so. Just a minute, I think I know why...

 

Not yet, but today I got information how to do that

 

Here the fix for Envy15:
HWiNFO32 v3.60-988

 

Nice..what about the E14?

 

Envy14 advanced monitoring is the next step (next week if all goes well).

 

Great...can't wait..

 

Thanks, it works now.
Is 3500RPM normal? seems high considering i can hear it spin MUCH faster while playing battlefield bc2. Max could be 6000RPM than?

Also GPU temp is around 52C, while on-die info tells me it's 47C and shader 49C.
What does skin DxP1,2 and 3 mean? (they are around 28 to 35C)
GPU fanspeed on the bottem of the list still tells me 30%, which is incorrect.

Is changing fanspeed possible? or are you still searching?
I really appreciate your work, thanks!!

 

I guess the values should be ok, since I got a confirmation directly an engineer working on this particular model.
Try to run a high load on CPU or GPU and then you can see the highest value in the Max column. Which fan reports that value? Would be also interesting to check the various loads and verify if the fan values reported are ok.
The Skin temps are sourced beneath the touchpad (for measuring of skin temperature).
The 30% GPU fan speed is a common mistake - this reading comes from GPU registers directly, but in case of several notebooks the GPU doesn't control that fan, so it reports constantly 30%. That's the reason why I add EC readings..
Fan speed control should be possible (I already have the know-how), but it will require more work. I'll try this later...

 

Testing low and heavy use (rpm fanspeed)

 

Hm... seems that some readings return erratic values sometimes. Not sure yet if the cause is the EC or something else...
Maybe the fan values need to be divided by 2 or 4?

 

Yeah, some bugs in there.
TDP CPU should be 55W max (with turbo boost enabled)
Most max values are also not correct.

Good news about the RPM monitoring.

I ran Prime95 (100% CPU load)
And max fanspeeds seems little under 6000RPM (!)
I would really like to control fanspeed, because the envy has an amazing cooling system, but fans kick in quite late (when it's already 70C+)

GPU en CPU2 seems not to be correct. When running prime, gpu fanspeed go up, cpu2 fanspeed stays stable, doesnt it have to be the other way?

 

Yep, maybe the fans need to be exchanged, I'll discuss it with the engineer but he is not available until monday. What happens if you run a pure GPU-load, which one goes high?
It seems that only the 144 C values are incorrect. Or on some reading the erratic values were scanned and so they slipped into Max and stay there.
Could you please close/open sensors (to reset min/max values) and try again ?
The best would be to Start logging and attach the results, so I can verify those values exactly. Log for high CPU load and high GPU load.

 

I restart hwinfo and max seems ok now.
GPU and CPU2 have to be switched (tried furmark and CPU2 temp rose)

CPU idle: 3000RPM
load (100%): 5800RPM

GPU idle: 3000RPM
load (100%): 4800RPM

(already exchanged monitoring temps)

 

Okay, I'll switch them in the next build. Moreover I think the Fan values reported seem quite high, maybe they need a divisor (by 2?).
Anyway, the weird Max values should be checked.. Could you please create the 2 logs (Prime, Furmark) and attach them?

 

HWiNFO works great so far, but I have problem. I cannot get the Windows gadget to work (it says HWiNFO is not running or gadget is not supported) Any ideas?

This is great info. I keep my fingers crossed.

 

Have you enabled the Sidebar Gadget in Sensors / Configure and assigned values that you want to see there ?

 

Didn't see that. Now it works. Thx

 

Any resolution for the ACPI error? I have the LPC/EC support disabled and this seems to solve the problem, but I don't get any fan speed and some other temp data.

This is on the Envy 17.

 

Unfortunately not yet. You might want to try v3.61 that I released a hour ago, but I don't know if it will show any improvement. I haven't seen such ACPI conflicts on other systems yet. Would be interesting to know if it interfers with the ACPI itself or some other component that is communicating with the EC..

 

Can fanspeed be changed now?

 

Still not possible.

 

NOT possible now, or NOT possible in the future too?

 

Mumak said he actually has the know-how on implementing fan control to ENVY 17, but hasn't tweaked with it yet. So it is possible. This is what he told me, as I'm also very interested in this feature.

 

Not possible now
I'm hesitating to implement this yet, because messing with this kind of stuff might cause unpredictable results in case a conflict happens during the communication with EC...

Btw guys, I just got info directly from an Envy developer that the Envy15 thermal design is very bad.. Just in case you didn't know it

 

yeah I think everyone knows the envy15 gen 1's thermal design is really really bad.

gen 2 was better.

 

It's sometimes bad. In 19-20C roomtemp it's rather good, even while playing intensive games, the cooling system is amazing (small but still with hardware between midrange and highend and not overheating)

But everything changes if your roomtemp is higher than 24C.
While browsing it becomes warm, while gaming really hot.

The cooling system is a lot dependent on your roomtemp, but really a lot. You can relate this to the metal casing, not the fans or airflow or something like that.

Easy to fix it.
Make it 2mm thicker (which they did with the envy 14) keep the 3 fans they have now in the envy 15 (gen 1 & 2) and dont put the CPU on the left side close to the touchpad but in the upper left.
The problem seems to be the i7 quadcores. Intel didnt do its job this time. 15W idle is unacceptable. Anyway sandy bridge is going to be A LOT better for the mobile platform.
