Four flashes. Battery isn’t recognized by laptop.
Just replaced my dying battery with one from ifixit.
The white charging light appears when I attach the ac adapter, then I get four orange flashes.
The internet says this means a bad battery. Did I receive a bad battery or is there something else that could be at play here?
EPILOGUE: I followed the recommendation, started the process. For giggles, I unplugged and repeated the connection and realized it had been user error. Fixit troubleshooting 101.
Questa è una buona domanda?
What happens if you leave it on charge for a while, does it stop flashing?
Have you tried re-installing the old battery to check if the problem is still there, assuming that it didn't do this before?
