No, was a last breathe.

Now i have BAT1 totally died, in a way that BAT0 does not load and if i try
to suspend the laptop, it dies if i unplug the power cord.

Looking araund i've found:

I've tried to reset EC, with no luck.


Currently i have:

seems just the latest.


I can try to ''reflesh'' the BIOS/EC?

Someone have some other hints?


Thanks.
