My friend has Acer Aspire 6920 but unfortunately he got that his CineDashMediaConsole stopped working. the cine media console shows full volume and mute. The bad condision is your Aspire 6920 will freezes, refuses to work or even it will turn off.
Have you ever found same problem? Actually, the solution is really simple, you only need to take battery out and put back in, everything will be fine.
