Regarding the trackpoint and touchpad on the Dell m4400 and the Lenovo t500. I've understood that most people think the touchpad on the t500 is better. But how big is the difference between them? Will I even notice any difference? Is it the software or the hardware that makes the difference?
View 5 Repliesseems they can all be configured the same , surely they arent charging extra for that paint job , there must be more to it than that ?
View 5 Replies View RelatedThe M4400 supports dual-channel DDR2-800 memory.
The M6400 supports dual-channel DDR3-1066 memory.
Both systems have a FSB that operates at 1066 MHz.
I'm trying to understand if the different memory technologies ultimately make a difference for computational (i.e. math on large data sets) performance in these particular machines.
Consider an M4400 and M6400 with identical CPUs and amounts of DDR-2 and DDR-3 memory, respectively. And suppose that all relevant memory latencies are identical. For the sake of this question, I don't care about power consumption and heat (which is obviously a benefit of DDR3).
Question:
Since both machines support dual-channel memory operation, the maximum effective bandwidth of the memory bus is doubled. So the dual-channel DDR2-800 can achieve 12.8 GB/sec transfer rate, while the dual-channel DDR3-1066 can achieve 17 GB/sec transfer rate. In either case, these rates are higher than the 8.5 GB/sec rate that the FSB can achieve, so it seems that performance in both machines is limited by the speed of the FSB (1066 MHz). Is that correct?
For more info on matched FSB and memory ratings under Core 2, see:

I am considering of getting myself a laptop for personal CAD and design use.
I am looking to buy a resonably priced Quadro graphic laptop and hope it last for 2 years or so...
Could anyone kindly advise me on if the Dell Precision M4400 would be a good option? (below is the spec I am thinking of going for)
Processor: 2.8Ghz T9600 Intel Core 2 Duo
Memory: 4Gb (800Mhz, DDR2)
Graphics Card: NVIDIA Quadro FX1700M (512Mb)
Hard Disk: 320Gb (7200rpm)
just got my m4400 and upgraded to vista business via the dell disks. Now the backlit keyboard dosen't work. It was working under XP. It on in the BIOS and the controlpoint.

I am looking for a notebook for my girlfriend. She studies architecture, so she needs something with a powerful GPU, high resolution display, but not too heavy (she has to lug it with her every day all over campus). We don't want to spend more than ~$1500, and hopefully get it for less than that with discounts (either through the University or her mother's job) .....
I want to get a durable work station notebook and narrowed down my choices to the Precision M4400, HP Elite Book and Thinkpad W500.
Getting the Precision from the Outlet seems the cheapest option. Anyone have any experience getting a laptop from there?
I'm a bit out of the loop. Is the M4400 due for a major refresh any time soon? If so when, and what major components will be replaced (gpu, hopefully)?

View 7 Replies View RelatedI sold my Asus G1S last week and now i am looking to replace it with another more modern 15.4" laptop with decent graphics card and good screen. Dell m4400 and lenovo t500 both fit the bill. I am leaning more towards a refurb dell from the outlet. I am lookign for answers to a few questions to help me make up my mind:
I heard good stuff about both WXGA+ LED and WUXGA RGB-LED panels on this model. What about WUXGA CCFL panel. Where can I find specs on it? Is it any good or terribly dim like the one Lenovo uses?
Is heat a big problem with m4400? My Asus was heating up to the point that it was uncomfortable to keep on my lap and was very noisy and I kind of want to avoid that again.
How good are Dell refurbs? Am i going to get something that has been trashed before or are these just open box returns? Also is it possible to get them to give extra discount over the phone? There was a 15% off coupon a few weeks ago which is over now. What are my chances of convincing them to give me a discount?
Also, If I do order new, would it be possible to convince Dell to price match the M4400 to a T500 or W500? Did anybody ever have any success with that?
Just got my Precision M4400 and a Logitech bluetooth mouse. Can't figure out how to activate bluetooth, or whether it's even installed as ordered. Blue bluetooth light above keyboard is on, but can't find bluetooth in Device Manager, or in system tray.

I recently received a new m4400 (with a T9400)and had a problem with one of the cpu cores running 6-8 degrees hotter at idle (not under load). When I told this to Dell technical support, they reordered me a new notebook.
Here's the problem...
I received my new replacement notebook. Although the cpu cores are now the exact same temperature at idle, once I start running some programs (simulation games, etc.), one of the cpu cores runs 7-8 degrees consistantly hotter than the other one. If I stop playing these games, both cores return to the exact same temperature .....
I've been watching this board for a while, and decided to register finally, as I am looking to purchase a Precision for school.
My previous notebook is a Latitude D810 with WUXGA LCD, with a higher end configuration, (2.26Ghz, 2GB, X600 128MB, 320GB HD, Bluetooth) which served me well for the past four years.
I wish to get a high end model as well this time around (With the same resolution), hoping to get the same longevity

Is it possible to purchase/add an aftermarket BlueRay dvd player that would fit in the Precision m4400?
I may be getting one through work, but noticed that there are no options available for this item.
Any m4400 owners with Blue Ray dvd players?
Just got my m4400 finally. Quad core + uxga/led. The led screen went pink or something when docked without a/c power. It also flickered a bit when I was using it on battery (only happened once).
The fan is way loud (using bios A11). I found the I8kfanGUI program to control the fan (works pretty good) but what's funny is the laptop keeps wanting to turn the fan to full speed, then the tool kicks in and turns it off again. So it spins up, back down, up, back down .....
I have spent the past 10 minutes trying to search this forum for the answer and came up empty-handed. Simple question: does the M4400 support 3 Gbits/second or is it limited to 1.5 Gbits/second? I know the entire ThinkPad line
(T400/T500/W500/W700) models are limited to 1.5 Gbits/second, which limits the usefulness of a higher-end Solid State Disk like the Intel X25-M. Thanks for the info!
At work we ordered a Dell Precision M4400 laptop
Processor: T9300 or T9500
RAM: 4GB
OS: vista Basic
When the laptop arrived I took out the 80GB HDD and installed a Western Digital 320GB 7200 RPM drive and created 2 Partitions so that we could dual-boot with Windows XP SP3 and another Windows XP SP3.
I've searched and found a lot of info on audio crackling, but I'm not quite sure if that is the issue I am having.
The best way I can describe the audio problem is that, it on occasion, once ever 30 seconds or so, music, or audio that is continuously playing will stutter and skip for a moment, like the computer is under heavy load
I'm planning on buying a refurb M4400 soon, and I'm wondering if the user community has any input for me. Are there any features I should make sure to get (backlit keyboard is good, I hear)? Are there any features I should be sure to avoid? Are there any problems commonly experienced that I should look out for once I get the system?
I haven't ordered it yet, but so far I think I'm looking at the T9400 cpu, 4GB RAM, FX770M gpu, CCFL WUXGA screen, ~250GB@7200RPM HD (could be 160GB or 320GB, depends on what's available). Up for debate still are 6 vs 9 cell battery, fingerprint reader (none, internal, FIPS), OS (if I can get 64-bit Vista Ultimate that'd be great, otherwise XP Pro w/ Vista Business license).
The intended usage here is software development (mostly Java, some C/C++) and gaming (Far Cry 2, CoD4/5, maybe Crysis?).
I don't get it. I thought it should be Fn + F4. The numlock light is on, but the embedded numerics do not work. What am I doing wrong? Some BIOS setting or what?
View 1 Replies View RelatedI was all set to buy a refurbished Precision m4400 until I started to read about gpu downclocking heating issues that some people have when playing higher end gpu intensive games.
Is this still a problem with this particular notebook (where a lack of sufficient cooling design will force the gpu to downclock when trying to play gpu intensive simulation games)?
Do you recommend this notebook if I plan on using it for gaming 50% of the time? I need to buy a business notebook through my company but do not want to buy this particualr one if I can't game with it. (My other option would be an XPS 1530 with a worse 8600gty gpu option.)
Any comments or suggestions would be greatly appreciated to help me decide whether to purchase this m4400 notebook.
How is the Build quality of Precision M4400 compared to the M65/M4300 ?
I was taken aback by the following post: ...
I currently have a Latitude E6400 that I LOVE...except for the display. I bought it from the Outlet and it was such a good deal that I couldn't pass it up. But it has the WXGA (1280x800) CCFL display and I really wanted the WXGA+ LED.
I'm in the process of finding its replacement, again from Dell Outlet. I'm seriously thikning about stepping up a size to the E6500 and getting the WUXGA (1920x1200) display. The Outlet also has a surprising number of Precision M4400s in stock, too. I've also found several of those with the WUXGA display that I want.
I don't "need" the more powerful graphics card in the M4400. But I really like (make that- LOVE) the exterior design of the Precision
did anybody ever try to successfully run and configure Windows Server 2008 x64 on a Precision M4400?
It installs fine, but I cannot get some components working with the Vista x64 drivers - like WiFi?
Wondering if the the CPU and / or GPU on the Precision M4400 / M6600 are user upgradeable? Both in terms of is it physically possible and how does it affect warranty. If it voids the warranty, how likely is it that they can tell that it was upgraded if you swap the oringinal components back in before sending it in.
