Hi all, I got a new 15 inch MacBook Pro for Christmas and I'm having some problems with it. First is my battery. I believe that it's defective. I've only been surfing the internet for the past 30 minutes. When I started my battery was at 100% and now, thirty minutes later it's at 85%. That's 15% in 30 minutes. 15 goes into 100 about 6 2/3 times. 30 times 6 2/3 equals 200. Divide by 60 and that equates to only about 3 and 2/3 hours of battery life. Apple advertises 7. I'm not doing any high performance tasks, I only have safari and mail open. Do you think my battery is defective? My second problem is with my Belkin Thunderbolt to HDMI cable. When I plugged it into my Sharp tv the tv began to flicker. I messed with the resolution and couldn't find a solution. I unplugged it and switched my tv back to the cable input and it still continued to blink. I had to unplug the tv for about 20 minutes for it to work properly again. I tried it on my Hisense tv and it worked but it looked horrible. No matter which resolution and other settings I tried, the picture was horrible and didn't take up the entire screen. Does anybody have any solutions to this? Thanks!
