best advice I could give is, buy a lap top from best buy and buy the extended warranty.
If it breaks down they'll repair it up to 3 times. If it breaks down a 4th time, they'll replace it (you have as much credit as what you originally paid toward a new one).
Sometimes you'll get lucky like me, took in my laptop for the first time 2 years after purchase and they sent it to the repair center. Shit has changed so much that they no longer had parts to repair it, so I got a new one.
downside
3 year warranty is $250
each time the unit is exchanged, you msut purchase a new warranty
but I think the upside is well worth the $250
I paln on having a new lap top evr y2 years or so, amd it'll only cost me $250
