Hi, I run MBP without battery 99% of the time to safe its 300 or so cycles and I occasionally trip the mac safe adapter (which i find gimmicky and annoying) by maneuvering MBP around when sitting down & the cable gets snagged momentarily on corner of coffee table etc and out goes the power !! Is this causing any damage ?!? I havent noticed any ill effects. I also understand from reading other threads how the processor speed reduces without battery but thats ok considering most of my use is limited to web browsing.. Thanks , N .
