Today a friend called to ask me about ejecting a CD from the Dell XPS M1330. Apparently the eject button does not work and the only way to remove the disc is to reboot the computer.
After doing a search on Google I found a blog post here that gave the solution to the problem. It is a BIOS update which Dell rates as important. The link to the BIOS update is here. A word of caution however, please ensure that you read the download and installation information fully before attempting a BIOS upgrade. If done incorrectly, your system can be rendered unusable.
