I'm having problems with the DVD rom
when I write CD /DVD it doesn't end the disc!
A laptop computer by Fujitsu Siemens Computers released in 2008.
You only need to unscrew a pair of screws and then pull the DVD unit off. Then put the mounting brackets in the new unit and attach it to the laptop.
Be sure that both unit have the same connection technology, IDE or SATA.
Search in this web for a DVD replacement manual. It is a quite standard procedure so any guide will be usefull.
