I have a theory on the possible cause of the latency issues on the E and M series Dell's and a potential solution.
I usualy don't post on theory. I'd rather prove the solution beforehand and just post the tutorial, but unfortunately I'm in the middle of huge deployment and my spare time is extremely slim for now.
If there's a few of you who are willing to run some group testing I can guide you on what we need to do.
It just involves some test benchmarks before, a (possible) fix, followed by test benchmarks to establish if this actually resolves the issue.
Some important criteria;
- OS is Vista x86 or x64
- Have a very good understanding of Windows, particularly how to backup and restore your system (if needed). In other words an advanced user.
I'm going to need to count on your honesty on this one. I won't have much time to get you out of a mess if you land into one.
Would be good to have a good cross section of systems ranging from E64/6500's and M's both with onboard and discreet GPUs.................
I received the Dell Precision m4400 on last friday.
I did not know about the latency problem that I read on these forums AFTER the horrible fact that I'm going to explain.
In fact, I was watching an avi file, in Windows Vista (the preinstalled OS), when sometimes the play stops (as the computer is under much load) and then resume the play .....
I've posted about this problem in several forums but thought I'd try for a solution here..
Essentially my issue is with a continuous DPC latency spike every 5 seconds on my laptop..
Normally, it wouldn't be an issue -- but I'm using this laptop for high-end real-time DJing and it causes a "pop" when I'm playing (using Traktor Scratch.) More info about what I've tried already, fully detailed in this post on Native Instruments forum here.....
like in several threads mentioned installing not the DELL-WLAn drivers but the broadcom Mini-1510 (http://ftp.us.dell.com/network/R212337.EXE) reduces the latency/crackling sound problem.
This worked also on my E6500, so I'm very happy.
I also tried to change hd from IRRT to AHCI, disabling DELL WLAn 802.11a, installing Matirx driver 8.2 or 8.8 and so on.
I decided to upgrade to Windows Vista Ultimate after having run XP Pro on my M1530 for the past 6 months. XP ran flawlessly on the machine, but I wanted to bring the software up to speed with what's currently on the market.
So far everything is fine except for on minor issue. I am having a random spikes of DPC latency that are causing a brief 'stutter' or 'crackle' when playing audio or video files.
The problem was initially quite bad, but after installing the drivers found at Crackle Sound FIX for the WLAN 1505 card the problem has gotten significantly better. But as you can see, it is still an issue:
I'm running a D820 and I just installed Vista 64 Ultimate. I ran the entire install while disconnected from the dock and everything went smooth (SP1 and all patches afterwards).
After connecting the laptop to the dock I'm getting a very annoying latency with my mouse and keyboard. The mouse stops responding for as little as half a second, up to 4 or 5 seconds depending on what
I'm doing. While typing, the keyboard will also repeat the last key I touched when the issue occurs
I have the GQ61-420US with the 320M dual processor, IDT sound chip with latest driver, plus updated video driver (etc.) now running Win7 64, and have a strange audio delay problem, first discovered when attempting multi-tracking music. In fact, if I just have the monitoring enabled on the built-in microphone, and tap on the computer there is about a 1/10 sec. delay when it comes out of the speaker. I downloaded a latency checker program mentioned elsewhere on this board, but it doesn't show much of a problem. I don't believe the CPU is overtaxed here, and believe it might be driver-related. I've checked the IDT control panel, which is rather bare-bones, having no settings for effects such as delay that I might have inadvertantly checked.
Recently i ordered a Dell Studio XPS and like many of you with dell's,my main use was to be for audio production,dj'ing or any sort of thing pertaining to music.After ordering and then reading up online,ALOT of people are having problems getting the latency and/or pops skips & jumps out of their sound source.
Some say the problems lie within the Lan card,some say video card.And most importantly,Dell does not have an answer to the problem because they are not trained to understand audio type situations(Unfortunately).So...Here is where we are going to solve this thing(or try really hard because besides that...these are prett good laptops otherwise) Once i get mine in the next 3 days,im going to tell you what i did because i WILL fix it or at least try hard and fail.
my friend is thinking about purchasing a new laptop for his mother. The HP DM3 laptops look to the best solution so far since they are both lightweight and have great battery life, something he thinks she'll appreciate. One thing i'm not sure about is their ability to run Adobe Photoshop CS4 smoothly.
I don't use Photoshop very often and when I do, it's on my laptop, which is pretty decent in terms of specifications. Will the program run fine on a laptop with a Intel CULV or AMD Neo processor and integrated graphics? Which leads me to my next question:
Which Pavilion laptop would you recommend? Are they both similar to each other than the processors?
Which series is better? The B series is for business. This series is only 5.9lbs with 15.4'. On the other hand, the CW series is around 5.5 lbs and it is only 14'. What do you think? Have you ever try B series? 15.4' is pretty good for movie.
I am having an issue that I can replicate on any E-series laptop and on XP, Vista and Win7.
When using A2DP audio (headphones) the BT370 adapter will just randomly disappear. I can stream audio for any amount of time, 5 minutes, an hour, all day long. So it is completely random.
It is no longer listed under device manager and turning on and off the toggle switch does not bring it back. The only thing that helps is rebooting .....
I have seen some AC Adaptors for latitude e-series (Latitude E6500 & E6400) and they was very thin and light.
However, yesterday I received my M4400 and the AC is too big and heavy in comparation with que latitude ACs.
Reviewing the orders, I've seen that Latitude's have "450-11869 Power Cord: European 90W AC Adaptor 2 pin" whereas M4400 have "450-11970 Power Supply And Power Cord: Worldwide 130W AC Adapter with European Power Cord".
I'd like to buy an M1530 but it hasn't been refreshed in forever. Does anybody know if Dell is phasing out this series to replace it with the Studio XPS series?
I'd like to get any computer of comparable build quality, i.e., with a magnesium alloy frame but options around this price range seem limited. I don't want a Thinkpad
I have been the happy user of many a Dell Latitude over the years as my employer has chosen Dell as the global IT Hardware provider.
I have been enjoying a D410 with XP without much hassle and have now been asked to choose between a 6400, 4300 or 4200. I have written off the 6400 already - I think - as it is too big and I like the portability of my current D410.
Also I have an Alienware m9750 at home for gaming and an old Sony Vaio FS Series that I have bequeathed to my GF, so I am chosing the new Latitude for business only.
Would this be considered a good deal, or does anyone know of any other deals (e-value codes, coupon codes, etc.) for the Studio XPS 1647?
Also, I noticed some people are wanting the ATI 5000 series for the SXPS 16. What are the benefits of the 5000 series over the 4670 and what is the holdup? Does it require a new MB layout or something? I will mainly be using my computer for Internet/email, photo editing, and occasional HD video and DVD editing...I am not a PC gamer. So, would it worth waiting for the 5000 series? I'm sure the 4670 will suit me just fine, but I've read that it is 'last year's technology' and I generally like to try to get the latest available technology at the time of purchase...
Just wondering what we use in terms of Power Management, whether its part of the OS or its Dell's Control Point Manager, and whether it affects the fans kicking in or not under comparable settings.
I use an M4400 & an E6400, both have the latest BIOS revisions, and both use Vista's native applet, selected to "Balanced".
I looking to buy a new Latitude E-series but I have one worry. During the years with D-series I have built up a "infrastructure" of AC adapters in my home, car and my offices so I dont have to carry around these bricks. My wife and kids use them too since we all have compatible Dells. Very convenient indeed.
Looking at the specs for the E-series adapter it uses the same voltage as the D-series (19.5V) and the power tip looks the same(?). So, can it be so wonderful that the E-series can use the D-series adapter? I don't want to shell out money on 4-5 new adapters...
Regatta blue? (My Favorite) Regal Red? I know a few people on here have blue but i was just wondering how widespread the color choices are among NBR members?
Typical Dell issue. I just got my new Dell 15 5000 series laptop. Spent 1 hour setting it up. Took a break closed the lid and now its dead. I have a power light on the front but screen wont come back. Have held the power button down for 10 seconds then retried it but nothing. It is plugged in just no screen or activity.
