The only problem that I have with my HP is that it no longer functions as a laptop- the batteries no longer recharge, so it has to be plugged in to be used. : /
Of course, it's probably my fault as I rarely turn it off. xD
Being on for 2 years straight... probably caused the batteries to overheat... but, even after replacing the battery, I still had the same problem.
Oh, I have one more complaint: my laptop's screen is so wide that pretty much all wallpapers are distorted/look like crap on it (except for the preset ones, but who uses those, really?). My next computer is going to have dual (average-sized) monitors, for sure.
Mine's a HP Pavillion zd8000 by the way.
