i just picked up an acer 6930. first of all there seems to be a million different sub models of 6930s. in one place it states my model is a 6930-680 and in another place it says it is the zk2 model.
(1)Can anyone help me understand what model i exactly have?
(2)second of all there was no recovery cd included. is this normal for these, or am i missing the cd? i can't seem to find any information on this.
(3)there is a button for virtual surroundsound on. i press this and nothing happens. it is clear and appears to me it would light up. am i not doing something correctly?
