Hello all. My macbook stoppped charging after some time of not being used. Looking for the solution in Internet I've found out that it is a common issue of MacBook's batteries - if battery discharged to zero point it won't be charged again(weird behaviour in my opinion). There are two ways, I see, how to repair my macbook: 1) Buy a new battery 2) Repair the old one. Every local workshop is ready to repair my old battery, but they want about 50-70$ for their work, i think it is too expensive for bringing to life the old battery. I decided to ask you, dear experts, if anybody already came across this issue and know how to restore the life of battery using own hands. Thank you in advance.
