somehow the markings for the slots (usb,hdmi,memory card etc) comes off rather easily. Mine is somewhat fading. Also, i just realised my headphone jack isn't working properly. The sound comes out distorted even after adjusting/ trying with other headphones. Any suggestions? Oh yea, my touchpad is equally errr.. 'crooked' on the bottom left too which i guess is common among other users?

errr, i have no idea also. i dont rest my palm or anything on the laptop. I keep it in a laptop sleeve though. if that can rub it off then the markings isn't permanent?
as for the headphone jack issue i guess its choosy with earphones? so weird. it finally worked normally after the 6th earphone i tested it with.
not really crooked just the bottom left sinks a little and you have to touch nearer to the middle line to left click comfortably.
