Solved! acer E5-575-33BM won't turn on

[driali]

My laptop was left on and after 3 weeks, it shows no signs of power (Ac or battery).
Neither blue light or orange light shows.
Adapter was tested good for 19v.
I did reset by power button, battery reset form pin hole, disconnected reconnected battery but no use.
So I left in on charge overnight,
In morning ,saw oracle battery light blinking, I was able to start it still plugged in to AC, battery was showing very low percentage and then I did clean shutdown.
I disconnected AC power and put back cover on .
But again, no sign of power with/without AC.
Any suggestions ?
Should it work on AC alone even if battery is dead?
Again I leave it on charging ant orange battery light starts blinking after 12 hrs.
This time I will keep it on for more time and see it battery gets any better before starting.

If you are getting no power unless the charger is connected, you likely need a new battery.

Third time it turned out better. In 3 hrs, battery light became stable orange.
I started laptop and battery was 37% and charging. I selected complete updates and shutdown. In few hours battery was fully charged and blue light came on.
Now laptop works on battery alone too.

Conclusion: It appears that these Acer laptops won't work on AC if battery is fully discharged.
Secondly, 1st charging if battery is 0% takes very very long time.

Both are completely possible. Different devices have different 'issues' so to speak.
