Works now though, also with the smaller charger. Normally a Mac will shut down by itself before they drain completely, but I’m not sure what happened in this case. Maybe the battery was so drained that the smaller charger couldn’t kick it into life - it does have lithium batteries, and this can also happen on 18v power tools lithium batteries, where you have to do a few things before they will charge, if they are completely drained. It was on zero percent charge though, but started charging normally after a few minutes. Then I tried plugging in the 85w charger from my own 2013 15”, and it turned on instantly, battery recognized too. Tried SMC and PRAM resets multiple times, didn’t work. Pressing the power button alone would spin the fans in slow bursts, but nothing else. Charger glowed orange, and I was able to power on if I held down the power button while plugging in the charger, although it ran with fans on full speed, and battery wasn’t recognized.Ĭhecked out the battery and connectors physically, but it looked good, apart from some dust. However, it just started doing it by itself. Just had the same issue with someone’s 2012 13” rMBP. I mean, the laptop works great with the power cord conected, nothing fails. Should I get a new battery to test it out? I get the battery icon with an X only on login screen, after loging in i don't even get the battery icon. In coconutBattery, the battery doesn't show up.Ĭould it be the RAM or SSD causing trouble? The laptop was bought in 2013, the battery has 3 years of intense usage, I don't know the cycles or life as the laptop wasn't mine. I looked over the internet, tried the SMC reset, the P-RAM reset, tried disconecting the battery and reconecting, all that to no success. This graph displays the average health of this model of Mac, as a light green line, and the battery. This tab contains the following graphs: Battery capacity over time. coconutBattery Online will now open in a new tab in your default browser. I tried disconecting the power cord and the laptop shut down. Make sure coconutBattery’s ‘History’ tab is selected. I wanted to upgrade a Macbook Pro from 4 GB of RAM to 8 GB and switch the HDD for an SSD.Īfter doing so, I installed macOS Sierra and noticed that the battery icon was gone.
