Dell :: M6400 Power Adapters
Jan 10, 2009
I need to get a extra power adapter for my M6400 Covet for home use. Taking the 210 watt power supply between the office and home is starting to take a toll on me (I take public transportation daily).
The 210 watt power adapter is only available with purchase of a port replicator. I could save some money an get a 130 or 90 watt power adapter, but I'm not sure what the downsides are. Does the 130 or 90 watt power adapter just take longer to charge? If the 130 or 90 watt power adapters degrade my performance, then I won't consider it.
What are other M6400 Covet owners doing for extra power supplies? For those of you who are using 130 or 90 watt power adapters, did you notice any decrease in performance?

I've searched for some answers to this, but have been unsuccessful...
I've got a Dell Precision M6400, and would like to be able to use it on an upcoming trans-Pacific flight.
Does anyone have experience with an airplane adaptor which would work with the M6400?

Precision M6400 : Is it possible to put the GPU (2700M) into a low power mode ?
Often, when I'm on battery, I do low GPu work, like text editing and compilation, or giving presentations. Also I use XP 64 bit; all low GPU work.
Can I downclock the GPU or undervolt it or do something to conserve energy ?

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".

if I could use my girlfriend's Dell Studio 15 adapter for my HP HDX 16 notebook. The connector looks te same, and the volts/amps are on both adapters approximately the same.
Is there a chance I'd damage my HP notebook or her Dell adapter? Or can an adapter never damage a laptop, it just works or it doesn't?
And if it is possible, is it also possible the other way around? (my HP adapter to her Dell notebook?)

I m trying to install ESXi 5.0 as a VM in LATITUDE E6430 ,but it gives me the following error
No network adapters were detected.Either no network adapters are physically connected to the system or a suitable driver could not be located.A third party driver may be required.
I have found that DELL customized image is available but only for servers (tried that too but not working)...

Yup me again, in my hunt to determine if M6400 is right for me as it costs just about as much as a used car, I want to make sure its a good investment before I buy it.
What is the main difference with the M6400 and the M6400 Covet?
I configured both with the same specs and the Covet is about $900 more in price?
Does orange paint really cost that much?

I have the blu-ray 5920g with bluetooth and a 8600, but no turboboost.
Not that its a massively great feature, but I'm guessing my motherboard has an empty spot where the turboost should be? and while these adapters are floating around I'd like to chuck one in there.
What is compatible withe the 5290g. I know turboboost never really took of, so was there only one type? or am I limited to the specific tuboboost adapter from another 5920g, or can I put in others?
Also how would it interact with readyboost and ram in 32bit and 64 bit OSes?
For example You can't go past 4GB of readyboost in 32 bit, even if your system ram is 1gb or 4gb, the max is always 4gb.
With 4gb of ram and 4gb of readboost will you still be able to use a further 2gb of turbooost in a 32 bit OS? Or are readyboost and turboost seen as the same as far as the OS is concerned, thus you will eiether have to use 2gb of readboosy and 2gb of turboost or 4gb of readyboost and no turboboost.

I'm a proud new owner of a MBP 13-inch. couple of matters.
(1) A good skin/sleeve/cover/case to protect it on the go. Ideally I'd like a very lightweight and elegant skin or shell that's on all the time to protect the exterior from wear and tear, without trapping too much heat.
(2) I need a sleek padded case to carry the unit and typical accessories (charger, adapters, mouse) and other small items.
(3) I'm looking for a convenient laptop stand for my desk to set the MBP alongside an external monitor.

So at first I was confused but now I understand. First official, completely top to bottom support for all mobility cards (in the specified range of course) will come out with 10.3. What they didn't say that SOME mobility cards will be already supported with 10.2 and our " Dell (Studio XPS 16 Mobility Radeon HD 4670)" is on that list.
This was posted in another thread, but this wasn't the focus. They also have beta 10.3s...but I thought it was neat that official 10.2 WHQL certified drivers supported our card ....

I have a Dell Latitude D800 that will not power on. When the power button is pushed the green power indicator light comes on, the CDROM spins for a moment, but then nothing happens, there is no BIOS information displayed, no power on self test, no Dell logo. It just sits there with the green power light on.I have tried removing the power & battery then pressing the power button for 10 seconds (actually, I have tried as long as 60 seconds). I have tried to turn on with the power connected but not the battery. I have tried removing the connector cable for the power button and the connector cable for the display and then reseating them.

Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.

When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?

I have just installed an i7 2670Qm on my T420 today.The machine will crash pretty soon after booting up, with the screen having colorful vertical and horizontal lines before it restarts itself and give the memory error beeping pattern (1 beep-pause-3 beeps-3 beeps-pause-1 beep).So then I took out one RAM from the bottom, and the machine appears to work normally again, more or less.
In the OS (Win7 64), The power manager alerts me that the 65w AC adapter is giving not enough power, so the laptop is running on battery. I thought I just need a 90W AC brick so the laptop will work as it should, so I am arranging a 90w one to come in later. But on a second thought, if the battery cannot start the laptop with 8GB of RAM properly.
Is it the CPU or RAM or Mobo or something else? Where should I look?The machine works fine with the previous CPU i3-2310m and 8GB of RAM.The RAM modules I have are 2 x 4GB Samsung 2Rx8 PC3-12800S-11-11-F3.The BIOS version is updated to the latest 1.46.

I enjoy the feature of automatically powering off the optical drive in power manager. My issue is after reformatting my T530 the option is there until I do an update using the Lenovo ThinkVantage System Update. One of the updates seems to remove the feature from the power manager.

After replacing the fan, I have a power up issue with the laptop. Basically, the laptop will only power on with the power cable disconnected at the motherboard. It was by mistake that after the fan was replaced and everything was put back together, that I noticed that the battery was not charging.
I then reopened the machine and reconnected the power cable to the motherboard and nothing - no power.
When plugging in the power source with the battery in place, the LED adjacent to the power socket lights up WHITE then stays ORANGE and will not power up. No other lights, no fan noise, nothing.
If I remove the battery, the LED adjacent to the power socket lights up WHITE and stays white however will not power up either. Same agin, no other LEDs, not fan noise, nothing.
I have now opened the machine back up and disconnected the power from the motherboard. Put it all back together and the laptop powers up as normal with the battery and it works fine. (Well until the battery runs out anyway).

I'm having some issues with my MacBook's USB hub. I have the macbook from 2007 I believe that has 2.0GHz and 1GB of RAM. WHenever I connect my iPhone to the USB port to sync, it pops up with this dialog box that says that my iPhone is drawing too much power and thus the USB hub will be deactivated.

i'm waiting for the M6400 I ordered. I didn't choose any of the Dell bags cause I wanted to get it myself.
So here's the question. Which bag to choose - especially regarding the big power supply.
I already did a search:
Targus - Atmosphere ....

I guess I'm about to get a mobile workstation. I already got an M90 it is great. Only one dead/stuck pixel and the front panel silver button paint came off in a few month of usage.
But I love it. So I am thinking of getting an M6400. Can you back me up on this one..?? Please if you own one tell me the pros and cons.. Have you noticed any Dead/stuck pixels.
What about built quality, feel, comfort, performance, heat, cooling, fan noise, screen quality ( thinking of LEG or RGB LED)..
Any creeking noise while opening the lid or holding or working on the laptop?? Any thing you can tell me about this beast of a machine will be a great help for me indeed

my M6400 is here - just wanted to post some first impressions.
X9100 - 3.06ghz
4GB DDR3
Quadro 3700M
1440x900 WXGA+
Wireless 5300
Bluetooth 370
DVD+RW slot load
Silver Color
Backlit keyboard
Webcam
2x 80GB 5400rpm drives
2 Intel X25-M 80GB SSD drives will be replacing those 80GB's.
First - my first thoughts are that this system is Fantastic!
The screen is great - its an LG, fantastic colors, no dead pixels. Typical viewing angles for non LED screen, not great, but not noticeably bad either.
No noticeable bleeding, no graininess - very happy with the screen.
Ran 3Dmark 06 (1280x800, stock drivers) - 11,619
GPU temp was around 80 C - not bad at all.
So far, very happy. Putting the SSD ddrives in now - will post more thoughts as I do more. Will post pics ASAP.
Update 1: 2 80GB SSDs are in place - this has Intel's Matrix Storage which allows the creation of one RAID1 volume (which I will use for valuable data) and a RAID0 volume for the rest of the space - this is very nice - get the benefits of both types of RAID in one system!
Update 2: The power brick is completely absurd. Its HUGE - 210W. The good news is that I plugged in a 130W from a M4400 and although I get the popup about the AC adapter not being at least 150W, it does charge the battery and allow the system to run. To me, this is an acceptable alternative to lugging around the giant brick, at least for most things on the road - Later on, I will test the system with this adapter and see what kind of slowdown is caused.
Pics:
RAID Setup:
Next to a M4400 (that I believe I'll be returning very shortly):
Next to an older E1705 - these are virtually the exact same size - its astounding what new tech can cram into the same space

does anybody know when M6400 will be available with LED option?
I read - in some post - that the LED displays have quality issues.
if I order the notebook now (with CCFL option) can I upgrade to LED afterwards?

I have an Aspire 6930 that suddenly died and will not power on. The LED power button was dark and unresponsive. I performed a power reset and the blue light on the power button came back on until I pressed the button to try to restart the laptop. When I did that, the blue LED immediately went dark and stayed that way until I did another power reset. It never gets to the point of anything powering on. Is it a problem with the battery or it the laptop toast?
This is a real bummer since I just replaced the hard drive a few weeks ago and replaced Windows Vista with Linux Mint (which btw is blazing fast compared to Vista).

Whilst working away at my desk, M6400 docked it just powered down.
Pressing the power button causes it (the power button) to light briefly and then go out. Pressing FN+Power (as requested by Dell Tech) does nothing at all.
I've tried it with another PSU (I got 2, one with M6400, other with docking station) - and if you plug the PSU in, and then hit power on the laptop - the blue light on the PSU goes out - and doesn't come back on till the power is cycled. The M6400 does nothing during all of this.
The PSUs work just fine with my D820.
Dell techs are coming tomorrow to fix it. I'll let you know what they say!
