Envy series problem---high pitch sound, source confirmed!

I open up the my Envy 15 WITH POWER ON and finally find that those annoying sound is come from -------the electric resistance!! 100% sure.

 

fixing is done how?

 

it's always that...


...I'm surprised this wasn't already known. particularly on battery power, when this issue really crops up. also if you undervolt the CPU. you hear a whine from the resistors in many computers.

 

the 'electric resistance'.

Which in particular? Consider that there are probably a hundred or more individual resistors in the machine on top of the other components that offer 'resistance'.

 

Don't know how to fix it yet...it even have annoying sound when overclocking GPU and also simply visiting websites....

But my 1st Envy 15 2nd Gen did not have such problems.

The sound is come from the biggest resistance labeled as 1R5 from the picture.

 

i found a thread over in HP's forums that might resolve the issue in the interim:

HP ENVY Gen 2 Noise (Morse Code like) issue - The Next Bench

this noise appears on my machine after windows is loaded up. appears to be an issue with power states and low voltage causing the noise. on my machine, the noise was loudest right around the memory/wireless module compartment.

i created the .bat as described in that thread, then had to create a .vbs to run the .bat invisibly. it significantly reduced the noise. but it uses more power because it keeps the processor busy. as a result, the fan will run faster/fluctuate as the cpu gets warmer.

 

Any chance you have those files around?
Edit - nvm, I found the lines

Thanks tho! Gonna try it out on the envy 14

 

just google search for running .bat files invisible.... .vbs file.

this is a temporary remedy, since it seems to occur when windows is loaded and running, some kind of low power state of the cpu is causing it...

probably cheap electrical components used on the motherboard or the hardware is being driven outside it's designed habitat.

i explained the issue to HP support, they recommend i send the laptop in.

 

Does this apply to the Evny 14's whine?

 

i dunno.. im gonna try it out once i find the file somewhere

 

alright guys creating a batch file actually works to stop the whine!!

heres what i did..

1. Click Start
2. Click Run
3. Type: notepad and press enter.
4. Once notepad is open, type the below lines in the file or copy and paste the below lines into notepad.

@echo OFF

:LOOP

Echo "Hooah........"

goto LOOP

5. Click File and click Save; browse to where you want to save the file. For the file name, type "Stopwhine.bat", and if your version of Windows has a "Save as type" option, choose "All files", otherwise it will save as a text file. Once all of this has been done click the Save button and exit notepad.

6. Now, to run the batch file, simply double-click or run the file like any other program. Once the batch file has completed running it will close the window automatically.

------

you can run this file invisibly (still shows in task manager) and auto run it on windows start up.

now the things i noticed were this will probably drain your battery faster because my cpu jumped from 5% to around 20% load. also the fan will be on even if you disabled it in bios.
but ill take the fan noise over the whine anyday.

so if your studying and the whine is killing you, plug in your batt and start the bat file.

and if your planing on playing games or doing anything intensive, you wont need the bat file anyways and it would probally slow down whatever your doing if you have it running in the background.

as someone said earlier, this is a temporary fix (or permanent if you want to keep the file)

anyways goodluck!

edit:
i have the envy 14 with the 450i5

edit 2:
and yes, i know it suck to even have to do this

edit 3:
credit goes to the guy from the link (above mine a few) for creating the lines.

edit 4:
im gonna do some battery test with this bat file.

 

this proceedure doesn't really apply to specific models, in general it applies to computers that modulate the voltage to the cpu in such a way that the resistors on the main board make noise.

my laptop gets a bit warmer when running this file, but no noticable difference in performance.

if you want to kill the process, look for it as cmd.exe under your name in task manager.

i recommend sending the machine back to HP. enough returns for this would probably result in a bios update or fix for the mainboard.

 

turns out to be a defective motherboard. mine is being repaired right now .. should be back home in the next few days ....

 

well, i got the laptop back. they said they replaced the main board. shortly after running the machine for an hour the sound resurfaced.

i complained to hp before i heard the noise appear again, because they scratched the bottom of the laptop around the removable panels. when i remove these panels (HDD, Memory) i use plastic cell phone tools to avoid scratching. it looks like these goons used a screwdriver ...

when they call back i will ask if they can send me a new laptop with a different configuration, because i'm not sending it back in and waiting another 10 days without a computer ...

 

When your first got you laptop ( not this recent time ) did you notice the whine right away, or did it take a bit of time to happen?

My replacement is coming on monday, so my question is there a special procedure where the whining appears, s.th where it is reproducible?

 

it did not appear right away, it surfaced a few days after i brought it home. in the documentation included in the return box with the repaired machine, there is a comprehensive list of components (generic) but none were checked off. on the HP order status, it doesn't mention anything was replaced either.

so i essentially got back a laptop that i was told over the phone the mainboard was changed. i'm skeptical of that now, and since there's scratches on the base, i want a new machine, because i sent it to them in new condition, hasn't been 2 weeks that i've owned it and had to send it in.

rediculous.

 

you should let HP know if the problem appears again, i think i spotted some posts on HP's forums about this same problem. if enough ppl badger them, they will issue a BIOS update to fix. it has something to do with some kind of low-power state being created in windows. when i run the infinite loop scripts (read this thread, you will find my temporary fix), the noise goes down quite a bit.

if you want, i can post up the contents of the scripts and you can create them using notepad.

this kind of noise rings in your ears even after the noise is gone, it's freakin annoying !

 

Thanks for that information. I will be looking out for it as I will be receiving my Envy next week. Please keep us updated on your story.

What kind of conditions does the noise happen under? Does it happen all the time or under certain loads?

Regards

Chad

 

idle in windows. with firefox and thunderbird running, it's still there. i don't mind running the infinite script file, once the .vbs file is started, it's always running even when you restart the computer. but it's causing more heat and more heat will result in an early grave for this machine.

i am convinced there is a faulty component on the mainboard or the ATI/i5 combo is the problem or something else mainboard related.

can everyone who's got this issue please post their hardware configuration here, so that i may bring this thread to HP's attention ?

 

1R5 is a choke/inductor not a resistor.

 

which part of the mainboard is this ? the sound seems to be coming from directly under the enter key (qwerty, not numeric pad). is this on the right side of the mainboard near the optical drive or elsewhere ? it looks like it's near an edge.

 

Guys, have you tried this possible solution out? It's really simple:

I tried it and the morse code noise went away for good. I had this same annoying problem with my ex-Envy 15 G2, and it sounded exactly the same as the one I experienced with my Envy 17 (though back then, I didn't know this fix). Good luck.

 

Didn't work for me.

 

i played around with that yesterday, it reduces the noise but it comes back.

i still insist theres something going on with power modulation on the mainboard or between the board and the wireless module. i keep bluetooth off and the sound is there. maybe if i turn it on this may change.

some chip, inductor or other circuit is not good or properly shielded.
upon my first service with hp i got different accounts by different ppl. in the end i was told by an accounts manager that the power brick was replaced. but that didnt do anything.

at this point its a candidate to get a bios update or if an update cant fix then i forsee they got a bad batch of mainboards in a bunch of envys.

i bought a 1011nr thinking the 1010nr i got may have been an isolated incident, but the 1011nr has the same problem. interesting because the mainboards for i5 & i7 should be different.

 

same happened to me!
