[Opgelost] Sessy battery fan error

Goedemorgen,

Helaas word mijn vraag / nieuw topic steeds gezien als spam door het forum hier. Maar mijn battery is gisteren vervangen vanwege een A-C short foutmelding.

de nieuwe battery heeft niet goed gewerkt en geeft in de logging aan dat er een FAN ntc fout is. Het laadt en ontlaad ook niet. Ook niet na een powercycle en firmware update…

wat kan ik nog meer doen?
