@ ukbrownpa - Well said!

Closing ranks to deny problems is bad.  It's all been said before, and I understand that you could be under tight constraints but if you're being excessively gagged or that it's actually your job to be a pain, then I must apologise for harassing you all about my high expectations of customer support.

I think that if trends continue then Dell could be making cut backs.

OK back on topic, Studio problems! (not the thread title topic per se)  Well well well what do we have here....... as reported in another thread, there have been some audio issues, clipping at the beginning of sounds.  Now I don't often experience this clipping effect, only a handful of times over 2 months.  Anyway, I found on Intel's PM55 motherboard tech doc, white paper or something,

5. Intel® 5 Series Chipset and Intel® 3400 Series Chipset Intel® HD

Audio Interface Intermittently Does Not Play Sound

Problem: The Intel® 5 Series Chipset and Intel® 3400 Series Chipset Intel® HD Audio controller

logic may not be gated by DMI L1 entry.

Implication: Systems may intermittently not play sound on the Intel HD Audio interface Following a

DMI L1 exit.

Workaround: BIOS workaround available.

Status: No Plan to Fix

Now I can't remember where it was,(think I googled PM55 chipset) I just saved a copy of this extract, but it details all the known problems with the chipset.  What it's saying is that a bios workaround is available.  How effective, I don't know.  Has it been implemented, I don't know.  But I tell you Dell employees, if I was able to stumble across this, then don't you have access to this kind of info?

What I do know is that as an OEM, somewhere within the mighty Dell empire, there is a document/tech spec/engineer who knows all about this.  Maybe this is the actual Bios editing team?  Now like all oversized companies, information gets held up, collects in knowledge pools and is unable to escape/be disseminated to the frontline guys that take the flak.

I would suggest that one of you take this info, research its authenticity at www.intel.com or within the Dell Empire and go over to the audio clipping thread and reply to the poor sole that reported the problem!

Thank you very much for reading this long post.

I have searched...everywhere...online and in these forums. 

And at least a few bits of information are there, eg. http://en.community.dell.com/forums/p/19310587/19634176.aspx#19634176 (one of my posts).

You asked for "advice", and I simply wanted to express, that by purpose I was not advising you. I am sorry if you have read this as being intrusive.

could 1 assume that when the laptop is on battery only and running full power (no throttling)
then a 130w adapter could be used with no issues as it would seem the internals can take it?

I think that is a dangerous assumption to make.  If people have been able to use the 130 watt adapters without issues over the short term that doesn't mean that the internal components of the system won't be affected in the long term.

Dear Todd,

I am not a specialist in circuit board design and not a specialist in temperature problems, however, I have a sound general technical knowledge (as I expect, you have too).

Scenario 1: System runs on battery, no mains power supply around. All power saving features provided by Windows are switched off. System runs under full load (stress test), but no means used to disable any failure prevention measures (ie. no ThrottleStop or similar software).

Is this scenario 1 within the specifications of the system? It should be.  In this scenario, the CPU runs at max. multiplier.

Scenario 2: System runs on power supply.  Again, all power saving features provided by Windows are switched off. System runs under full load (stress test).  Because the system internally prevents the CPU running at max. multiplier, a software is used that enables the CPU to run on max. multiplier nonetheless (and does nothing more).

In scenario 2 the thermal load (and the spread of this load) should be roughly the same as in scenario 1. This means, if scenario 1 is within the specs, scenario 2 is within the specs as well.

However, to every one here it should be clear: Most systems are not designed to run on full load all their life (whether on battery or on mains).  However,  taken into account the information policy of Dell, we will never know what assumptions about usage patterns have been taken by your engineers when designing your notebooks (the throttling issue has been there with Dell systems long before the first I7 notebooks). But early adopters of i7 notebooks buy these because they want the raw horse power!

The AC and battery power will eventually meet up on the board, however they are not connected directly together.  you have the option to not charge the battery right, and so there is something between the two power inputs.  These componants may even have ripple/noise suppression on the AC that the battery doesn't have/need.  Eitherway, the Dell guys are right on this.  Just because the board can draw (Ha! had to change to draw from something that rhyms with duck but starts with an S - Over zealous swear detector) in more power via battery, doesn't mean that it's safe to use a larger AC.  It could just be as simple as the size of the wire between AC socket to the regulators being smaller than the wire from the battery.

The testing and quality checks needed for this simple task, are extremely time consuming and expensive.  Dell would not want thousands of dead laptops coming back. Be sure, be double sure and then check it again!

Your scenarios for thermal load are true, thermals are not a problem here.  My 820QM hits around 80C on full CPU 8 thread loads.  20C under the maximum (think Intel throttling kicks in at 108C but not sure of that), and as you say, full load for extended periods will shorten life expectancy.  Heat kills electrolytic capacitors, CPU's also but the limits AMD/Intel have are well researched.  At the end of the day, I expect 8 years of life from this laptop.

Are there any fixes for the Studio XPS 1645?  They are sending me a new one after I encountered random problems, lock-ups, heat, fan noise, etc...I'm wondering now if maybe I should just get a refund and go with something else?

@TinFL,

I have been following the threads here and over at notebook forum too.  So far I haven't seen a comparison between bios revisions.  I have not seen any discussion regarding which revision is the best/worst.  Generally the latest bios is best - may introduce issues too, but should generally be the best.  At least while under warranty, update while you can.  As out of warranty, a failed flash will not be covered.  In fact I'm only assuming that bad flashes are covered under warranty.  Can a Dell rep confirm this?

Thanks swapshop1, you actually expressed it better than I could    I know its frustrating, but on the one hand we are being accused of not doing enough product testing but on the other people want to rush through these tests.  (Again, I don't really blame them at all, I'd feel the same way in the same circumstances.)

And I don't know this for a fact but just a basic assumption but I would think some of that testing and/or validating would be done by the manufacturer of the motherboards (and other components).   Third party vendors tend to be very quick to get to work when its a potential sale on the line but maybe not always so quick when it comes to QA for something that ultimately won't generate much revenue. 

I don't mean to make it sound like we're blaming it on vendors.  That's not my intention at all.  The engineers are trying to look at this from all angles and possible resolutions.   I'm just trying to give a bit more context to why its not as cut and dry simple as some people believe that it is.

Pffff the last status is great... "no plan to fix" :emotion-7: I´ve posted this problems weeks ago here, thougt is was a sound driver problem... but if  this now is a chipset problem, don´t know if they ever can fix it? This issue bothers my since weeks, almost every short sound (ICQ, MSN, Win Info sounds, ...) is missed with this bug.

In Win 7´s device manager you can select the Microsoft driver instead of the IDT´s one. Then the cutted sound doesn´t appear anymore. But with MS driver the sound quality isn´t very good, so this also insn´t a real solution.

thanks swapshop

I actually contacted a dell tech and he couldn't really give me an answer either (just advised me to upgrade to the most recent).  He also said he wasn't aware of any issues with the 1747, 7 beeps, etc.  hmmm?  When I asked where to find fixes let's say from A01 to A02 he did point me to a link with other bios versions.  the A04 had a "fixes and features" so he told me to go to "fixes and features" on earlier versions...well A04 is the only bios listed that lists "fixes and features".  and the detail there was basically "enhanced features"  The NVIDIA driver I updated on another computer went into detail as to which issues on which games it fixed.  I haven't been able to get many detail answers when it comes to Dell problems...it shouldn't surprise me at this point.  although I'd like a little better performance, I use this computer for business so I guess I'll go with "if it aint broken don't fix it".  Maybe eventually there will be an A06 or A07 that everyone loves :)  I'll update then.

[quote user="eckythump"]

There is a similar problem with the dell 1737 dpc latency. Again the only progress was made by forum members but even then, like here, it doesn't fix the deeper problems.

Similar in what way? Dell did not respond, or there was no progress made by Dell, or the Dell fix did not address the deeper problems with the 1737? What are those deeper problems with the 1737, if that is the case?

[/quote]

 

 

Bill - Without being rude, you can't play ignorance on the Dell 1737 dpc latency issues... 1737 latency solving support was "DELL _Bill B" ...Do you actually think it is fixed??!!

On 04 sept 09 you even said, after fully accepting and understanding the faults - "I am not abandoning this issue until it's resolved. Thanks for your patience."

http://en.community.dell.com/forums/p/19279703/19550844.aspx?PageIndex=4

However, you have abandoned it - it remains abandoned by all Dell support since December - go have a look at the thread you added so much too, and where you provided so much faith there would be a resolution.

so to answer your questions here, and why I made the comparison in the first place,  yes similar in all 3 ways you ask!:

1. Dell no longer responds. (the last month of posts are sad "where did dell support go..hellooooo??" posts
2. No progress was made by Dell. (despite, like here, a bios release that fixed nothing, the dpc latency issue is 100% unchanged)
3. Forum members collaborated to find a elaborate, inconvenient,  "workaround" involving stopping core processes that really shouldn't be being stopped, and seriously affecting normal computer function (like the battery fix here, again by forum members, and hardly elegant). So yes, despite the very ugly workaround, that doesn't even work for all users, the deeper problem still exists.

I'm only glad you did at least give clear an honest advice in th 1737 thread, including recommeding I return my laptops while I still had the chance, Which I'm still grateful for. But that said, you have abandoned it, and alot of people are still there waiting for a fix.... It adds up to very poor support, and it doesn't bode well for things here.

Dear Todd,

My Studio 1747 is scheduled to arrive today.  Here in the UK we only have 7 days in which to return it for a refund.  I am very concerned about the well-reported throttling issue restricting the performance of the i7 processor in this laptop and worry that it won't deliver what I expect or what Dell's own descriptions and advertisements indicate.

I am pleased that Dell seem to be looking for a solution.......but where does this leave me with only 7 days to return the product for a refund? From what you say it seems unlikely that a solution will be provided in this timescale.  Would it not be simpler for Dell to make a statement guaranteeing the right to return the laptop within an extened period for a full refund (or a full fix with whatever new hardware, power supplies etc that might turn out to be needed) to reassure people such as myself who are considering sending the laptop back as soon as we receive it.  I can't afford to take a risk with the amount of money I have spent on this laptop but equally I have waited a long time and need a laptop now.  I don't want to send it back only to find a fix has been produced in a couple of weeks that everyone seems happy with and then find out by that stage I can't get the same build at the same price or I'm left with another month of waiting.

Could you clarify whether the throttling issue will be accepted as a reason for a refund within the warranty period outside of the 7 day distance selling regulation period. Such a statement would make me, and I suspect others, more likely to keep our laptops and put faith in Dell finding a solution.

Many thanks for your posts so far

Hi Studio owners!!

Just seen that my Studio 1747 i7 is on its way to me - first Dell told me that it would arrive 11-03-2010 but now its send.. I was actually calculating with the time spand - then these problems maybe had new solutions. Now I will start up the pc, see if its better or worse!

Its a bit funny that today there is a BIOS UPDATE A05 on the danish Dell site. The date of this Bios is 21-012010... then it should be the same that once was released???

 

Is there anyone that already tried this A05???

Best regards Peter

Hi all,

I have also noticed that even though my delivery date was very late next month it too is on its way and the A05 bios is also up in the uk..

I suppose its the same release that was pulled down last week but has now been "corrected".

The first thing i will do is extensively test the machine because i am a gamer so i need full use of its power,  if this does not meet my demands because of throttling then i already have my eye on an acer i5 with an ati 5650 at which point the dell will be going straight back!!

Peter,

I'm looking into this.   From what I know the A05 bios update should not be up and available but then again I could just not be in the loop on information.  I checked, it doesn't appear to be up on the US pages.   I've sent an email out to try to get more information and I'll post it when I get it.

Todd
