I have a Dell Inspiron 2650 that I bought several months ago. I now have a new CD-RW/DVD-ROM DRIVE (I recently bought this from Dell - having made the mistake of not including it in the original purchase). It arrived with no instructions - but it actually looks like it should just slip into the slot where the original drive is. Does anyone know how I remove the original and does the new one just slide in? Couldn't possibly be that easy?
