Brand new dv3-4101sl stutters, mouse and video freezes for few seconds

Hi to all...
As in subject, i bought a 999€ laptop HP DV3-4101sl ( i7 720qm - ati hd5470 - IDT HD fu##ing audio) and it has terrible stutterng problem. Every 2-3 minutes, mouse freezes, video freezes, sound stutters (like an old scratchy record), the everything backs to normal.

Now, i've read (i think) all the posts in this forum, and i've tried all of the solutions posted here, with no luck.
I've :

- replaced hdd with a new one, thinking bout a disk latency probl.
- replaced ram, even if the original ones passed over 10 memtest cycles
- replaced mini-pci wifi card
- installed newer or older IDT, ATI & Atheros drivers
- installed brand new OSes (win7 32/64bit - winxp - linux)
- disabled wifi, IDT audio
- run HP diagnostics, memtest, video memory stress test, burn-in test
- upgraded and downgraded bios.

and still the problem exists.

I called HP and they took my laptop, promising me they'd chenged the MB. this happened two times, but, actually, they told me : "the notebook is working properly, we just restored it to factory settings".

I wrote HP a mail with screenshots and videos of the stuttering ("simulated" by passmark burn-in test) and the shots of DPC Latency check with EVIDENT spikes (about 10000000000us) when the stutter occurs, even with no drivers or with audio and wifi disabled.

tomorrow i will call HP again, i will get really really really angry, 'cause i bought this fu##ing laptop more than a month ago and I cannot use it.


ok... now... what can i do?

thank you all and sorry for my english (i'm italian)

 

As you, I have HP dv3 4101sl (latest BIOS firmware F.23) and have exactly the same problem. On my opinion it is due to overheating. The overheating practically jeopardize the use of my laptop with complex programs, like video games or simulation software. Unfortunately, I purchased this powerful PC just for using these kind of complex programs.
I try to explain better which is the overheating issue. When CPUs are loaded, turbo-boost overclocks the CPU frequency up to 2.8 Ghz. In this condition (i.e., turbo enabled), by monitoring the CPU temperature I observed that the fan are unable to cool properly the CPU and the temperature grows. When, temperature reaches about 85° (in 1 mins), the BIOS turns off the turbo boost and this causes a freeze (mouse, keyboard, audio, all) of about 1 second. When turbo boost is disabled, the temperature becomes to decrease until the BIOS turns on again the turbo boost, then the temperature increase again and so forth. Every time the is an on/off switch the turbo boost for temperature issue there is also a freeze (both on Windows / 64-bit and Linux 64-bit, indeed is not an OS issue) of about 1 second and since the on/off rounds are frequently, these continue freezes jeopardize the PC usage.
A possible way-out is to switch off turbo boost (e.g., by reducing the CPU performance at 99% in the power settings) but I purchased this laptop just because it was claimed that it provides me a full functional I/-720 processor. I never see on HP site that turbo boost can not be used on this laptop so I hope that HP will solve my problem.
What I said is easy reproducible by HP support and by everybody by using, for instance, teachpowerup Real Temp -CPU temperature monitor software or any other software that, on the one hand loads the CPUs (even only one CPU) at 100% and, on the other hand, monitors temperature and turbo boost state.
I have already told my story to Italian HP customer care but they answer me " it is a normal behavior, anyway it is an Intel problem, contact Intel". This is a mad answer, indeed if you gone into a restaurant and the fish is not good, would you have to lament with the fishmonger ? or with the restaurant head ? I buy HP and HP should solve my issue, not Intel. Anyway, I think that there isn't a solution because the laptop has a bad cooling design, so the only contribution that we can provide is to advise against this laptop but unfortunately HP I has just removed this laptop from the italian market so our protest could be ineffective.

Hi and thanks for your answer

As far as i can remember, my cpu rarely become so hot. Its temperature was always around 70-72 °c.
Today I send back my pc to HP for the third time, again with the promise "we will change the motherboard"...
I'm crossing my fingers...
I really approciate the advice of setting CPU at maximum 99%, i'll sure try it as soon i get my laptop back (my hopes of getting my baby fully functional are really really low)..
However, i tried also with a cooling pad under the notebook and i tried even working outside (at 4-5° C) with the same results... My laptop hangs even if the cpu is almost idle (surfing the web with no flash and listening to music), so i imagine the causes may be many.
I'll let you know what HP will tell me this time.

Thanks again.

P.S. : @malupandre : i've also read your post in HP forum I will post a reply there

 

The problem you have is software not hardware. It's related to DPC latency and is a direct result of poorly installed drivers in HP's stock install. When i bought my dv5 it wouldn't even play a MP3 without stuttering.

The definite fix is to reinstall Windows yourself and use the latest drivers from HP's page, without extra junk like quickplay quicktouch quickwhatever.

 

he did several new install,but it can be an driver problem,maybe chipset or graphics card or hdd driver.

TS please post can you post what driver versions you are using?
Maybe someone with an dm3 can share with you what drivers they are using,and if they have any trouble with their machine

 

Ok guys
I know it's all about latency.. And about temperatures...
Today I got my dv3 back from HP.
Same problems...
So i tried disable Turbo boost (as malupandre wrote) or even forcing max and min cpu power at 99%. Still no luck

Then i thought about BIOS. I was using the last release (F23).. I tried downgrading to F16 but problems remain.
I wanted to downgrade a little more, but (for the DV3-4101sl) the oldest firmware is F16.
I remembered of DEV-4010sl, basically the same laptop with different VGA (mine has a ATI HD5470, the "4010sl" has the ATI HD5450).

So i tried downloading and installing DV3-4010sl BIOSes.. Release F8 - No luck
Release F5 (first upgrade from HP) - I WON!!

I'm using it since this morning, and DPC problems are disappeared.
My VGA has becoma a 5450, but I don't care, it's a 5470 with a 75mhz slower clock.
Now when temperature reaches 80-82°C and when temperature falls back to idle values (55 - 50°C), notebook is responsive and no more stuttering.

Last, but not least :
BIG DISCLAMER

I'm not encouraging you forcing a bios not made for your laptop.
I'm not responsible of hardware damages.

P.S. : HP, PLEASE, do something in the next BIOS release. You can do it.

 

Hi guys, I've the same problems with my dv3-4101sl.. I opened a topic on hp official forum and i'm waiting for replies. Link here:

dv3-4101sl Cpu Fan killing me!! - HP Support Forum

I saw that we are all italians, why don't make something against hp? Toshiba pc equipped with same cpu, ram, video etc. don't have any of this problems!!
:cry:
