Upgraded from win8.1 to win10 and  ssd , happily using win10 for few month w/o any issue. Suddenly 1 update last week  hang  my Inspiron 14z-5423 is dead. Only power on light, 3 beeps after awhile. Cannot enter to bios.

Gone through removing all screws and batteries ,still the same.

Is it worth sending to dell to repair? .
