Well, from my experience, the one good thing about Dell is that when something blows up (HW), they give you replacement that is better than the original. But the rest is pretty much what the topic title says.
And fixing it yourself is cool, but personally, I do not dare to open my laptop and delve into it's guts, because somehow I have no idea what laptop hardware looks like.
Sure, many calls will be about some trivial stuff, but on the other hand, if you start off by saying what is wrong, they may consider it, rather than ask 120 questions in given order with no regards to what your actual problem is. So yeah, again, what the topic title says.
