Hi... I have hp pavilion g6.. well I bought it in last August... I got some problem with video and audio... before some months video problem started... as I see videos in full screen mode(without charger... am mentioning it because with charger it never happened) screen's brightness increases all sudden... and then I have to minimize it and have to refresh then it became normal... and about audio... before some days... I shut down my laptop at night... and when I turn it on... there was no sound... I checked and found that my left speaker was not working and even from right side there was not hear able sound... yeah but in headphones sound is normal... any guess guys??
