I got my alienware m17x R2 last year and a few weeks ago for some reason the Optical drive decided to stop reading any form of DVD CD that i put in. I have tried all types (dvd movie, dvd games, software) but can't figure out why it has started doing this.

Please share the troubleshooting steps performed by you. You may check in ‘Device Manager’ if the wireless card is detected or not and if detected is there any exclamation mark, question mark or red X on wireless card. Please follow the steps below:

I have the XPS 12 Ultrabook. I would like to get a cable to run from the laptop to my TV's HDMI port. Should I go with USB 3.0 to HDMI or use the other port on the laptop, which I'm not sure what it is, the manual just calls it video port. Is it a DVI? Thanks
