So that's a very bad sign. Try the old generic reset before you call for repair.

Hey guys,
I just started a windows 10 update when My computer flickered out. My charger is making a beeping noise too, and the power strip no longer works.
Plugging the computer into a different socket with a different charger doesn't do anything: no lights turn on and pressing the power does nothing.
The computer is a less than year old Y50 Lenovo, with 8gb RAM and an Intel i7.
Any ideas about what's wrong, or what I can do?
