Lat. E6400 USB Powershare port

Hey there!

 

New Latitude E6400 owner here :-).

 

Any idea why even though PowerShare is enabled in BIOS, it's not working ?  I try to charge my iphone, but it's definitely not getting any power from the lightning bolt USB port on the left side...  Only then the laptop is up and running, but that's "normal".  The feature allows to charge even when the laptop is powered down.

 

Anything else I'm missing?

Nevermind; the iphone 3G is really picky about his power source and when the computer's off is must not get enough power.  It's working with my Nano.

Re: Lat. E6400 USB Powershare port

I am having the same issue with my iphone and support was no help. I have the bios set to Enable for USB Poweshare by my iphone does not charge when the laptop is off, by the way I have an E6500.  I guess I am looking for an official statement from Dell as to whether the iphone is supported or not. It would be a rather big disappointment as this feature help me decide on this line of laptops and to find in only supports certain USB devices, when that is not noted anywhere, will make me think twice on Dell next time. Thanks

...same problems here with my E6500. I tested a HTC P3300, Creative ZEN and a PS3-Controller without success. It seems, that this feature does not work with most of the USB devices 😞

Thanks for the update, I am going to call Dell Support again and push this a little harder.  My guess was that the USB port would output 5 volts when the computer was off, I really don't understand what the issue is.

Dell support has been no help.  I cut the mouse off of a usb cable and hooked up my multi-meter and the laptop is outputting 5.07 volts when the machine is on and also when it is of. I can only assume the iphone is looking for something else and when the laptop is off, even though there is voltage, it will not charge. If anyone has any other info, please pass along. Disappointed Dell owner.

I'm having the same problem.  Powershare USB port on my E6400 does not charge my iPhone.  I have not tried other USB devices.  Are there any answers on this?

Re: Lat. E6400 USB Powershare port

iPhones need to see a refference voltage on the 2 data pins (#2 and 3)

Dell powershare works perfect, the problem is that the iPhone is very picky with what it gets powered from.   When the computer is on, the USB port is recognized as both a data port and a power port.  But whne the computer is off, it only provided power to pins 1 and 4 of the USB, which is enough to charge just about any NON APPLE device on the planet...

 

there is a work around..  Products like this make it work.- http://www.boxwave.com/products/iphonechargingadapter/iphone-charging-adapter-apple-iphone_2661.htm

 

The product has a high resistance resistor that provides a low voltage signal to the 2 data pins, enabling the iPhone to charge using powershare.

Re: Lat. E6400 USB Powershare port

I received a corporate gift here in Asia that works pretty well - called the CSQUID....

check out...http://www.agreenc.com/

But I am not sure if they sell it to other than corporates. You can try to email them and ask. I carry this cable with me and it charges my IPOD and blackberry even when my PC is in standby. I would think it should work on any device that has an Apple connector or a small usb connector like on a BOLD but I am not sure....

Good luck.

I have a nokia e52 and same problem.  no use a t all if it wont charge when the laptop is off and feel if I need an extra device for it to work they should supply it as technically it does not charge phones when off as promised
