hiya all…this is my first post so please be gentle with me!! lol! My other half has got an Fujitsu Amilo Pro v2010 laptop. The combo DVD/CD-W is knackered, it wont recognise any discs whatsoever so I decided to treat her to a Sony DW-Q58A DVD burner. The only problem is…how do i get the old one out??? Please can somebody help me??
