Electric soundlags on HP Pavilion g7-1204sa

Hello forum,

I would like to enquire if anybody has had any issues with sound on the HP Pavilion g7-1204sa. It is running of a A6 processor and has some strange electric lag interference sounds when playing sounds while working on battery.

I have tried various standard options but to no avail. Any advice?

Sincerely yours,

Dmitry

Try to update BIOS, my friend just bought the same laptop today and has exactly the same problem, when on AC the sound is okay, but on battery electric soundlag starts to happen every few seconds while playing movie or when listening to music... We will try to replace the laptop tommorow
