Your external devices can charge via USB while the laptop is off.

 

its technically called USB PowerShare. Have you tried it and gotten it to work? I attempted to powershare for an ipod the other day, and it did not work.

 

Thanks for the correction about the name.

1. You need to enable it in the BIOS.

2. I find that you need to unplug / reconnect your device after shutting the computer down. This is a logical precaution to avoid some connected device unnecessarily draining the battery when you turn the computer off.

3. The facility is only available on the top left USB port.

I have tried it while the computer was plugged in - the other USB ports didn't charge, the USB powershare port did, it charged my SE Xperia X1.
Haven't tried it on just battery.
Have you checked the BIOS settings?
You can set how much of your battery can be used for powershare or deactivate the function. I set mine to 75% - so it's supposed to cut off powershare when battery level reaches 75%.

EDIT: John was faster

 

Does somebody know if I can connect 30" monitor with 2560 x 1600 to my E6400 using E-Port Plus Port Replicator?
My gfx chip is "nVidia Quadro NVS 160M"
On this web site, nvidia said E6400 support up to 2048 x 1536 (analog) and 1600 x 1200 (digital) resolutions.

However, under "Features & Benefits" they said:

Dual-link DVI (TMDS) Support for Highest Resolution Digital Displays
Additionally dual-link transmitters enable driving the industry's latest, large and high resolution flat-panel displays up to 2560x1600.
http://www.nvidia.com/object/quadro_nvs_notebook_fbs.html

Now, I understand that i cant get 2560 x 1600 via VGA port, but since E-Port Plus Port Replicator got DVI-D, its possible to use higher resolution using the docking station?

 

Thanks for the info.

 

I have had my E6400 for 7 weeks now and overall I am satisfied with the computer. There is no such thing as a perfect laptop. I have purchased a lot a laptops at work and every laptop model has some problem. The E6400 is a a good compromise of features and performance to a competitive price.

I still think though that I should maybe have got the previous model Latitude D630/D830 instead to avoid some problems with a new model but the Latitude D series is not available anymore so it is too late to think about that. As for alternatives to Dell, the Lenovo T400/T500 and HP 6930p are more expensive, at least if I want match the features I have in my E6400. And the cheaper HP 6530b/6730b doesn't offer DVI output on the docking station if I have understand things right.

I think 1440x900 is too small for 14.1" so I ordered my laptop with 1280x800 instead. My screen is a traditional CCFL screen and it is good.

As far as I know, LED backlighting draws less power and lasts longer without deteriorating, am I wrong? My 5.5-yr old laptop's screen at this point has to be used at max bright, and it still is a bit dim for my liking. It wasn't like this when it was new. That's the main reason I'm going for this screen.

 

oh john, i know it has to be enabled in the BIOS . It is, but at least with my ipod, I was unable to get it charging -- I havent tried with another device yet.

 

Quite true, and I have seen the same. These two factors plus, I believe, the LED backlight hardware should be more reliable than the inverter + CCFL are reasons why I decided a year ago that any new acquisition would have an LED backlight.
