Hello c4rlo4,
So you used your laptop until battery went to 0% then your plugged in AC,
but then the device does not turn on right away?
May you try to wait for a while after you plug in AC?
Or you mean you can't use your device on Battery no matter what, only can use it on AC mode?
If so, please kindly send your device to service center for further examination on your battery.
Thank you.
