My guess is no, you won't be able to "bring it back to charging again". Only 131 cycles and the battery is toast? I'm curious as to what your normal charge/discharge cycle may have been, did you ever use it unplugged from the charger?

Unplugging from the charger wouldn't make a difference.

I expect thermal damage.

i used it all sort of ways but the problem is i sometimes use it for travelling it then i put it aside for months to use it....i have to do the control command option thing to wake it up.....

But now i didnt use it for months and i'm travelling right now, when i reached my destination i found out it can't charge, i have to plug it only....

Any solution to bring it back to charging? any idea if 131 is too much or is this normal?

131 cycles is not abnormal. The "Replace Now" indicator could be the result of normal battery depletion, or could indicate a defect.

For power or charging issues, try resetting the SMC, but there is no way to restore battery health once it declines.

The link below should answer most, if not all, of your battery/charging questions, including tips for maximizing battery performance. If you haven’t already done so, I highly recommend you take the time to read it.

If you let the laptop sit for months without charging then the battery is almost certainly dead and there's no way to charge it again.

It is a well known property of lithium ion batteries that if they are ever completely depleted, it is physically/chemically impossible to charge them again.

Luckily your laptop is dead and you aren't that Japanese guy who imported a Tesla that got stuck in customs for a few months and by the time it was released, its $20,000 battery was worthless.

Ouch! That's painful to hear!
