Chosen Solution
My battery shows an x and is not charging. The macbook works only with the adapter but when I remove it the mac shuts down. I bought the mac in 2010 and it has only 134 cycles. The battery is not removable. Can someone provide a solution ?
Please give us the last three figures of your serial number. Next, is the X Red or Black. Next download and run Coconut Battery and let us know your results. http://www.coconut-flavour.com UPDATE Try resetting the SMC Shut down the computer. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. Release all the keys and the power button at the same time. Press the power button to turn on the computer. Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
I’m having the same issue - plugged in a new battery, and I’m only getting a black x. I’ve tried resetting the SMC several times, but I don’t think it’s working. It’s most obvious that something is happening when I do the key combo while booted - the system immediately dies. But regardless whether it’s booted or not, the magsafe adapter light doesn’t change or flicker - is just a constant green. I just bought this adapter new a few days ago straight from apple. The reason I don’t think the SMC reset is working is because when I plug in the adapter with the lid closed, the computer boots (sound and all) then if I let it go to sleep and open the lid, I can’t get it awake again without a hard reboot. This is the type of “weird” behavior that the help pages indicate the need for an SMC reset.
