To those who care to help a intermediate mac user: My Macbook: 17" Mid 2010 i5 2.53 8GB RAM (upgrade from OWC) OS: Lion 10.7.2 (Most recent Update) Problem: Macbook will freeze when being charged up from 85W Magsafe. Note: Magsafe has No visable signs of frayed wire, and charges computer perfectly. Although, When plugged into Macbook, I get about 1 minute to do anything and "BAM" freeze...No response from mouse, no response from quick escape keys. NOTHING! When not plugged into power supply: MBP functions fine. No freeze, no problems. However, I am using this as a recording studio computer (Protools 8.0.5), and I can not bleed the battery just to be able to operate this Mac! What I have tried: PRAM (Nothing), Unselecting Graphic Switching Box (Nothing), Turn Off Bluetooth (Nothing), Repair/Verify Permissions (Nothing), Turn OFF time capsule (Nothing), Do a Vodoo dance....You get it NOTHING WORKS! What I have not tried: Going to Apple Genius Bar (Don't care to visit apple zoo), Re-Install Lion (Did when I bought it used, and had to migrate everything from capsule which took forever!), Replace 85W Magsafe (Seems to work, but could be faulty?). So all in all, before I throw this computer from my balcony, can some one please give me advice. Your help will mean so much to me because I need to start working on my album, and I am losing my faith/trust in my apple product. Thanks eeklipz P.S. I have read the hundreds of forums posts in regards to the monitor plug in problem, the NVIDIA issue, the EFI 1.9-2.3 updates, logic board,....blah blah blah! Important thing I should add: My lion/and all Mac files where migration added (Wirelessly). Could this cause some problem in a driver?
