I think the problems you experienced is to blame on HP; not AMD. HP makes terrible laptops with all sorts of malfunctions.
But for that price you should've gotten an i5 on that Acer. I don't think you did a good purchase.
My current Acer with an i3 was >$700
the AMD system annihilated the Intel in performance...when it worked.
I actually just got the HP back after repairs under warranty. I just haven't tried it yet lol. Just sitting in the back room without a battery
