Some questions about the XPS 17 (9720 and probably others ) in the Dell pdf's
XPS 17 9720
Start off : XPS 17 9720 Setup and specifications pdf :
Pg 8 : there are 5 devices ontop of your screen , 1 rgb/IR camera , 2 IR LED's , a camera status light and ambient light sensor. So why if you shine with a flash light , do I find 2 more holes left of those 5 ? (not the 2 microphones really on top of the lid) .... NSA peek cams ?
pg 18 , ten finger touch display , what do they mean by that ? How do you use 10 vingens on a display ? (yes maybe cleaning , haha)
In " Laptop reference guide pg 33, there are some gestures don't even work with 2 fingers , like the rotate clock and counterclockwise.
pg 19 Sensor :
accelerometer , what does it do in a computer ? How to use it ?
ALS ambient light sensor for panel backlight control > how does it work , where to enable or control it , what if someone (me) has a cap over it ?
All the pdf's Dell gives for your machine are not really a comprehensive user manual , is it ?
Why can't I put the battery level slider in My Dell >Power>settings>charging>custom below 50 %.

Ok , for those that saw the holes too , Dell techsupport came with a reasonable
explanation. Dell media support here on the forum/community was rather useless after more than 2 weeks .
These holes are for the Proximity sensors :
Wake-on-Approach (WOA) and Walk-Away-Lock (WAL) function.
This is not a function on the XPS , although we have the driver :

You need The Dell Peripheral Manager.

Not sure if installing this on an XPS would enable this function.
I would have thought the camera or IR camera would do this , but apparently not.
At least it is better than extra spy camera's ...

Ok , some pictures of the extra mystery holes.
It is very hard to photograph , especially alone , holding a flash light and camera, not dropping it on the computer !

Well no answers from the community here , so I contacted the chat , because Dell cares ...
Wow , the support here in the community is not much help . I did not get much of an answer about how to use 10 fingers on the screen .
Not much on the accelerometer... is used for things like stopping the HD when it senses an acceleration like a fall. But ... there is no HD in a modern machine , nor is there place for one . So why ? The fans ? Doubt it.
As for the ALS sensor , no help there , but this would have been the easiest one to answer and I found out myself by accident. Right click on Dell Premiercolor in systemtray > ambient light and select.
Why did I ask this ? Because I have something over the sensor , and I would like to know whether that has influence on premier color app.
As for the mystery holes , they needed pictures and are working on it ...
