modding Atrix lapdock to charge other phones?

[neotekz]

Ive since moved on from the atrix but kept the lapdock to see if i can use it for a hdmi monitor and charger. I now have the galaxy nexus and wanted try and use the lapdock with it. Im going to order the MHL adapter for the galaxy nexus to connect to the lapdock's hdmi with a female micro hdmi adapter. Ive read that the lapdock can receive HDMI input from other sources besides the atrix but will the lapdock accept HDMI source from a MHL adapter. Another problem is that in order for the Samsung MHL adapter to work it needs to be plugged in to a micro usb power source. I need to be able to use the micro usb from the lapdock if i want this set up to be portable.

i bought a micro usb extension and tried that but it doesnt charge galaxy nexus or Optimus P500. Unfortunately i sold my atrix before i got the cable so i cant test it with that but the micro usb extension charges all my phones fine when plugged into an AC adapter. So is it possible to mod the lapdock or micro hdmi cable to charge my other phones?

I can't speak for different phones made by different manufacturers (samsung, etc), but the atrix lapdock can be modified to work with other motorola weptop enabled phones. I am typing this on an atrix lapdock plugged into my Droid 4. I had to modify it when i bought it in order for it to work, but it was a simple 10 min job and it has been working well!

All I had to do was unscrew the cover of the hdmi/microusb ports, and flip over the connectors that were upside down for my use, and put it back together. A bit of shaving the plastic in the corners was necessary, but was not difficult. I am a happy user since this keyboard is a bit larger than the lapdock 100, and it was cheaper on craigslist than a lapdock 100.

Now I just need to see if anybody has managed to find any happy ways to hack/modify the atrix lapdock for greater functionality, like multitouch or scroll areas. If you have happened to see someone getting this to work, please do tell!

no need to mod!!! there are two powered usb ports on the back of the unit. when it senses hdmi, it turns on the usb ports and you can charge or power your usb device assuming 500ma is enough. not sure what it outputs, but it does charge a phone.

USB 2.0 = 500mA max.
