Hello All, Having some difficulties with my Mac & need some guidance as to what might be the issue. I have had it previously but then it seemed to have gone away but now it has re-occured, well yesterday. I was using my mac & the battery had dropped to 0:09mins left & got the pop up to say on reserve. In the time I went to go get my charger the mac had died, or so I thought. I plugged in the magsafe charger & tried to turn on the mac but nothing. The light on the charger stayed a solid green & the mac was making a clunky noise like it was trying to start but couldn't & the sleep light on the front wasn't acting like normal, it was on but then would go off with the clunk. The mac is a 2011 model & on OS 10.6.8 I left it alone for a day & have now managed to get it going again however when I started it the date & time were reset to 00:00:00 & the wifi password was also forgotten, other than that the rest all appears as it was previously. I had performed an SMC reset about a week prior as when I was trying to charge the laptop before the battery wasn't charging kept saying calculating but the SMC fixed it. From what I have read it could be logic board, battery or RAM, there isn't a genius store close to me so I am trying to see if I can resolve myself especially since it is well out of warranty & will cost me to fix.
