Hello and sorry my first post on this forum is a question but i'm really concerned about my newly aquired A150 as the hard drive makes a distinctive "tick" noise every 20 seconds or so. It doesn't sound like the crunch or grind of a failing drive but it definately doesn't sound right to me and i wanted to find out if anyone else experineced this or if it was just a normal noise. Any help and advise much appreciated, from the 30 minutes i've used it so far i really like it but if it's faulty i'll have to send it back :(. Knew i should have went for the SSD version as opposed to the hard drive. HAving never used Linux before, i thought iwould future proof myself incase i wanted to put windows on it so got the one with the 1gb RAM and 120GB HDD
