I have bought MacBook Pro 13 inch on last march 2011, recently my MagSafe charger sometimes doesn't work, many times light at the head doesn't show any light. Sometimes it works normally after attachment but many times it doesn't work, I can't understand where is the problem. Is it a battery problem or charger problem? How can I check the battery cycle?
MacBook Pro, OS X Mountain Lion (10.8.2)
Take it in for service.
If you want to check the battery cycle, click the apple at the top left and click about this mac. Then click more info and then system report. in system report, click power on the left column and you can find the charge cycle along with information regarding the battery. Hope this helped.
Thank you friends for your opinions, but I went to one shop that sells Mac product, they cannot solve my problem. I bought a new charger and now my problem is solved. Now my question is what are the factors that causes harm or decrease the longivity of this charger?
Where is the problem ?
