This is what it takes. For one thing, the screw for the hard drive cover was over tightened and stripped by Dell as I received it years ago. I only discovered it when I tried to remove the cover to put in a bigger, faster drive. I gave up. Even if I could get past that, this process requires me to completely dissemble the computer. I am not in all honestly up to it.
Your enthusiasm is noted and appreciated. If this was a desktop unit, I would be entirely at ease with the work, but with the Vostro I am not.
