Re: Scrolling lines on laptop screen
well ya, better circulation of course always helps. putting it on a laptop cooling pad does too, although its not usually necessary, honestly, I have known some people who are just silly stupid when it comes to their laptops, using them in ultra high heat situations, blocking the cooling fans, literally putting them on fuzzy blankets on their laps, and using them for massively long periods of times. todays lappy's are better of course and cooling is always a first priority when they design them now, but still you just have to be careful. plus the thing to realize is manufacturing processes are tight, but they always have variance. Sometimes you get a super laptop that just by a quirk works better then 100%, sometimes you get one that doesn't. you could theoretically just have one that doesn't. no one can tell.
the protective sleeve one is the ribbon cables. they're usually flat in a brown plastic data cables. often it's in the middle of the screen, to avoid the hinges, but different manufacturers do it different ways. I'm glad it hasn't turned up for awhile and the problem seems to be fixed though. hopefully it wont come back. See though, you could of ended up sending it in and having a tech do the exact same thing for $100
