Dear Mr. Blackthorn and List,

Regarding power concerns,  you may want to wait until Tablets come out that 
support AMD's Turbo Dock.  Just trying to bring this information to light.

In tablet mode, you’ll still get support for 1080p HD video playback,
 3D gaming, and other features. But you might not want to run 
CPU-intensive tasks that can drain your battery, so why does your CPU 
need to run at full speed? 


According to AMD, its Turbo Dock technology can boost your CPU and 
GPU performance by up to 40 percent when you attach a keyboard dock.  Turbo 
Dock technology should be available later this year when hybrid tablets based 
on the AMD Temash platform
 hit the streets. Temash is a low-power chip that supports 2-4 CPU cores
 and AMD Radeon HD graphics with support for DirectX 11 graphics.
If you are interested, here is a link to my source of this information :

I would like to thank all the members of this list for the helpful information 
that they have made available to this list.  

I am in the market for a tablet and one that I can either add a linux 
distribution too or root for full capabilities.  My main interest for rooting 
is because some OEMs want to control what gets loaded, but they do not seem 
interested in keeping the Op Sys updated or allowing the buyer the capabilities 
to protect their investment with being able to back the system and/or files up.

I noticed that this thread has moved on to smartphones,  but I wanted to bring 
this latest information to light.

Thank you for your understanding.

Sincerely,
Harvey Rothenberg

Interesting. I've used the high power Kindle charger and I thought that it 
might have the same issue. Is it Nexus-specific? Is there a specific high 
powered Nexus charger that I should be using? I didn't notice anything special 
about the one that came with it, and I'm pretty sure I shoved it in the drawer 
that all of my other generic USB wallwarts go in.

The Nexus 7 charging issue only occurs if you use a charger that can only put 
out 0.5A, or, more often, the Nexus can't tell and only uses 0.5A(like an iPad 
charger)

There are various incompatible ways for dumb chargers to indicate their power 
output. The one the Nexus 7 wants is the data lines on the USB cable tied 
together. If I use an iPad charger it will slowly discharge if the screen is on 
full. When I put in the extension cable I cut open and shorted the data lines 
together on the Nexus 7 side it charges fine with an iPad charger even with the 
screen on full, Wifi, GPS and Bluetooth on.

There are also reports of a similar looking problem when a compatible charger 
is used with a low quality cable that just can't pass enough current.-Steve
