I'm bothering you with all these questions just to be able to figure out somehow wheter the hardware or the power mgmt. software implementation is the cause of the sad fact that the device consumes more than 100 mA when in sleep mode (which figure is really weird when taking into consideration the other fact that the device consumes only approx. twice as much when not sleeping and idle).

Thx in advance.
I posted the pictures exactly so people with the right knowledge could have a look at this type of things :-)
I'll try to post the answers to your questions either tonight or tomorrow - if time permits-

- when looking harder on the U17 region I suspect now that it is an empty placeholder. Is that correct?
- there is a region (delta chip side, when delta chip is up and right, then the region is immediately above and including the usb connector, and streching to the right cn10 cap. sensor stripe connector) that is not covered by any hirez image. There are a couple of ic-s of interest.
- the picture showing U14 is out of focus. U14 should be the mcu chip, so could you post the type number of it.
Hi I've got the pictures for you. Have fun :-)

The 'empty spaces' on the board could be for the wireless functionality. It is common in consumer electronics to design a board for the 'full functional'-model and then leave off some components (and probably use different software) for the 'lower cost'-model.
The location where U17 should go seems to be 'shielded', which is normally only needed for high frequency ICs, which also points into wireless functionality.

Try using it as a notepad in meetings / to review documents. You WILL run out of battery unpractically soon.

Not (yet) got the guts to open it up for that though, especially not before some with expertise has confirmed that it will work.
