wht diagonal line? wht problem about the battery?
diagonal line issue is very minor issue anyway, its only noticeable if you have sharp eyes. its thin hair line when playing moving object like movies. some say it occur when a program playing a non-native resolution.
some user feedback:
"The only "diagonal lines" I have seen on my Z-590 are due to the dithering when choosing a resolution that isn't native. Then every laptop will have to do dithering, regardless of brand. The type of dithering may vary, but there will always be artifacts. With "alternating ordered" dithering, this can often be perceived diagonal lines. Whether it's better than the "splottiness" of Floyd-Steinberg dithering, or the circles of halftone dithering is debatable. At least ordered dithering uses very little CPU/GPU juice." arth1 from notebookreview.com
"I was looking at the Vaios today at the SonyStyle store and immediately noticed that. I appears when you move your head, or while moving our eyes around the image, like when following a moving object on the screen. The Z was playing a movie and it was very very noticeable. I cannot stand this! I was completely decided to buy the Z, but went back home without it. - ppeccin from notebookreview.com
"I started noticing it after using the high res Z for about 3 weeks. It's kinda obvious once you notice it. However, it is noticeable only when you physically move/shift/shake the screen. It really doesn't bother me that much given the awesome color reproduction and the great viewing angle of the Z's screen." - Jparity from notebookreview.com
my words: its very minor issue i can say and not a real big issues, i myself have play around some z's for quite some time at sonystyle store, and i havent notice this problem.
for battery drain issue:
the situation is like this. you fully charge your battery meaning 100% and keeping it inside the notebook. on the next day, when booting up the notebook, the battery level has been decrease around 75% ~ 95%. Normal notebook would has around 97% ~ 98% battery lvl. hope you get the idea.
