Hi All, I don’t know what to do anymore. My old battery now has 1210 cycles! and shows it needs to be replaced now. I bought new OEM battery and new OEM MagSafe charger but still the battery not charging . I tried to reset the SMC but still not charging! The weird thing that when I put may old battery back the MagSafe start charging (orange and green light) but once I put the new battery in nothing happens! No charge, no light, no nothing! Please can any one help or explain how come the old battery charges and the new one is not. Thank You Update (04/05/2019) Thanks all, Finally by chance i tried something and now it is working. I unplugged the battery, plugged in the MagSafe (charging with green color) and while its giving power without battery I plugged the battery back in and suddenly the green light changed to orange and started to charge till Full with green color. Thanks all for your help. Still need some help! I had another issue though, hope you can advise me about it. I have the original OS (OS-X Snow Leopard ) and was upgraded to OS-X Yosemite long time ago, while I’m preparing the system for my daughter I thought to upgrade to the latest OS-X thats compatible with my Macbookpro5.5 Mid 2009-13” What I found is OS-X El Capitan so i started to upgrade it through Apple website and while downloading/installing I got an error message that cant be complete with a screen (log file) with a lot of codes, I tried to do it again and again with no luck. and I couldn’t go back the previous one (Yosemite), Gladly i have the original CD so I started installing the original one which is “Snow Leopard” What shall I do to upgrade? What would be the best upgraded OS-X for this system? I read that some apps are not compatible with El Capitan, I don’t know much about this, just want to prepare the system with latest compatible and stable OS Thank you and sorry for the long message. Hope to hear from you soon! thx
To install the updated OS you’ll need to prep up an OS installer drive following this guide How to make a bootable OS X 10.11 El Capitan installer drive You’ll need to use a FireWire drive, Once you have it setup you’ll need to also back date the system as the installer won’t run with todays date. Manually alter your systems date to 2015 and reboot using the OS installer.
If your old battery is being charged but the replacement is not charging it is likely that your replacement battery is defective. I have run into situations like this and I finally got a good replacement battery after my 3rd try.
