I dunno. I can hear sound if I'm sitting close-- like in the desk chair with my hands on the keyboard. Otherwise, or if I want to hear any music, I use external speakers. (I keep the laptop at my desk, mostly, so it's no problem; I just figured, oh, well.... Great computer, can't have everything.)
The tag on the bottom of this says "type 0768A53" I was able to select that when I registered this box.
Yeah, I got some nice little external speakers that are powered by the USB port, so that eliminates at least one more cable.
I use this laptop whenever I travel and would need to google maps or mapquest for routes. Now I have a decent GPS device and only use the laptop to play DVDs. It's just like the not so old days as I now have a $1000.00 DVD player. And it's portable!!!
