I've tried it again, and my computer hasn't reacted in that way either. There is a diode on the DC-IN board connecting pin 3 to the ground to protect the SMC circuit. (Second in a series.) If you hold the Option key down before you click on the battery icon in the menu bar (Mac laptops only) you. The SMC uses the middle pin (pin 3) to talk to the MagSafe charger.
#Macbook pro battery x icon how to#
I restarted my computer, and the dead battery icon went away, and was replaced by the charging battery icon.īut, this is what it looks like now, and it makes absolutely no sense to me.Īny ideas on how to fix/if it needs to be fixed.Īlso, why would my computer shut down after being touched in the firewire port. Spare part: MacBook Pro DC-in board The battery on MacBook Pro not charging could be caused by a failed DC-IN board in the Pre 2013 Mac. Curious, I pulled the Power cable form my laptop, and weirdly enough, my computer didn't turn off, so my battery must of been working fine. Note: Portables using OS X Mavericks v10.9 or later display the low battery warning when the battery has approximately 10 minutes of power remaining. Enable the 'Show battery status in menu bar' check box to display the battery status menu item. I knew what this meant (happened to my mom's last generation MAcBook), that the battery wasn't working anymore. Follow these steps to enable the battery status menu item: Open System Preferences. Ive only tried this on my MacBook Pro, so I dont actually know whatll happen. The battery monitor on the top right of the Finder was the battery icon with a simple X in the middle of it. What if my Mac doesnt have a battery Well, then this probably wont work. I turned my computer on, and it appeared to be working fine, except for one thing.
I had zero clue what happened, especially since I literally touched it to the firewire port.
I have no idea why this is happening?Ī week or so ago, I was plugging in a firewire cable into my MBP, and after simply touching it, my computer instantly shut down.
