On a side note of this issue. I observed that when there are 10+ chrome tabs open, and when I connect to Bluetooth speaker there was cranky sound, as if there is hardware/graphics acceleration. When I close most of these tabs, then this issue was no longer there.  I performed below steps as suggested by Dell Support Personnel, and this issue seems to have been resolved. There is no longer cranky sound with 30+ tabs open for testing and no more freeze happening.

I am having issues with Dell Laptop 5502 . It freezes more often.  1). Whenever I have opened say 10+ tabs in my chrome browser. The system freezes altogether anytime. 2). When I am moving laptop (even gently), as soon as I put , it flickers for once or twice, the screen comes back, and it all freezes.
