I have a Precision 7550 provided to me by my employer for the duration of my internship, and I have noticed some EMI issues in the past few weeks.  These issues seem to only be caused by a lack of shielding on the corner of the laptop to the right of the mousepad, and so far I have been able to turn off my laptop screen by putting my phone or my Poly Voyager Focus 2 headset close to this corner.  I believe the wireless charging feature on my phone is what causes that issue, as my coworkers without wireless charging are not able to interfere with my laptop, however I have no idea why the laptop would not be shielded against signals emitted from the headset.  It doesn't regularly impact my work, as now I know and just don't put those items close to my laptop.  However, I thought it would be nice to note this and possibly shield to a higher standard in production moving forward.
