Well my battery in my MacBook Pro has been acting really strange. Not holding it’s charge and now it says it has a lot of battery then out of the blue it shuts off w/ no warning. Its been a few weeks since I have even seen the low battery warning. I did a bunch of research last night found out you get this problem if you have your laptop plugged in all the time. You’ve been warned!! For the last 3 weeks I have not been taking my laptop w/ me everywhere I go & it’s been plugged in at home. I tried to calibrate the battery but it failed cuz I wouldn’t get the low battery warning. Found another solution reset the SMC. This seems to work. I’m writing this w/ 18 min left on my battery. I’m waiting to see if I get the warning. Hope so. 16m . . . YES!!!! 9m left and I get the warning. I think things are fixed. Better plug in now!!
