Today I received a brand spanking new Dell Precision M4700. First step - replace the stock hard disk with my Smoking fast SSD (Solid State Drive).
Dell have gone to great lengths to make it easy to swap the hard disk and memory on this machine (unlike a certain Toshiba laptop I had to do last week that involved the removal of 28 screws and most of the chassis!)
Here are the steps, should you need to go through a similar exercise.
The Hard disk release slider will eject the disk caddy from the left of the machine. Just replace, then reverse the steps.
