New replacement battery for MacBook Pro not recognised
I replaced my Macbook's battery (after following the guide from iFixit) and the computer did not recognise it.
The only way for me to turn it on was to plug in the MagSafe connecter (which only showed the green light).
I then asumed it was a problem with the replacement battery (from eBay) and put back the original battery.
For some strange reason, the original battery wasn't recognised either!
I've reset the PRAM and SMC, but still to no avail!
I would greatly appreciate your help!
I have a late 2011 mackbook pro which battery indicator showed not working/replace battery soon, replaced the battery with one I bought from ebay. When installed worked as it showed to have 60 % change out of the box, I went ahead and charged it fully and then it drained after a couple of days and would not recharge. Waited a couple of days, it charged a 2nd time and this time i did SMC reset and calibrated as suggested. After the 2nd charge ran out, it started to drain fast and would not charge while plugged in. Replaced with the old battery, charged one time and now back neither old nor new battery will charge, megasafe doesn’t light up at all. Any suggestions?
