Hey guys, here's my situation: I'm a DJ, I usually work friday & saturday. Recently I've been playing music videos (display port to vga) and media is loaded from a POWERED external harddrive... I use software called VSL, created by Serato, it's very popular. Anyways, every night before a gig I charge my mbp (july 2011) to 100% battery. At the club, first thing I do is connect the power to the mac and will play all night while plugged in. At the end of the night my batter is at 39%!!!! HOOOWWW!?!?!? I checked the power adapter at the end of the night, it's red hot, as in DO NOT TOUCH it's so damn hot. I checked the power ratings for it, it's 85W the standard for mbp 2011 models. Here are my macs specs: 2.3GHz Quad-core Intel Core i7 8GB 1333MHz DDR3 SDRAM - 2x4GB 500GB Serial ATA Drive @ 7200 Sooo.... any idea?
