Hi Everyone,

When I connect the micro USB cable (included with N900 package) to my phone and the USB port on my notebook it works as expected. My N900 begins charging and asks to mount as 'PC Suite' or 'Mass Storage Device'.

I purchased an external power pack (http://www.xpalpower.com/us/products/xp4001/) and it also has two USB ports but when I unplug the USB cable from my notebook and plug it into my N900 it does not charge. I have tested the XP4001 power pack with my wife's Samsung BlackJack and my son's Nokia 5530 XpressMusic and they both work flawlessly.

Is there a hack or app that I can install to have my N900 charge with the power pack?

In order for a dumb charger to connect via USB, it must short the data connections. This is a new part of the standard, so a lot of power units (and older devices) ignore this.

I'm not aware of any way to get around this in software though.

Hmm, I have only used the USB data transfer cable from Nokia. I haven't used the adapter from XPAL yet. The kit did not include the micro usb adapter so I had to call them to order it. Maybe the adapter has the data connectors shorted...

I'll post and update once I receive the adapter from the manufacturer.

So pin's 3 and 4 need to be shorted?

CORRECTION:

I meant pins 2 and 3.

That's correct, yes. The phone can then detect that, and not bother trying to negotiate a data connection.

I went to the FREEtipsforlife.com site listed on the back and registered my XP4001. It doesn't have the N900 listed, but the N97 takes the same style connector; micro USB, which you can see here:

http://en.wikipedia.org/wiki/Univers...onnector_types

For the N97 it says:
For this model, you must also purchase a cable adapter (Model # WB18) due to the specific voltage required by the mobile phone. * This cable is not part of the Free Tips for Life program. Members of the Free Tips for Life program will have access to the cable at 45% off the original cost. Non-members can purchase the cable at it`s original cost through the online store.
However, when I went to order the appropriate connector (CB32), it also offered the magic cable adapter (WB18) for free. Of course, even though these are "free" it still costs €18,50. I'm not 100% sure that the N97 has exactly the same setup, but I'm going to give it a try. This ended up being one expensive battery - hopefully it works in the end!

Well, the connector stuff finally arrived. The N900 at least claims to be charging now when connected to the XP4001, but the battery still drops when connected. Further research to come...
