Battery Not detecting correctly, tried PRAM and SMC reset
I've been having an issue recently with my macbook pro, the battery isn't being detected by the laptop. The battery status indicator on the side of the laptop has one of the status lights lit, the one that is normally lit at 40% charge or above.
I have tried the usual solutions such as a PRAM and SMC reset. I've also tried swapping in a known good battery which had no effect. The fan isn't running at high RPM which would normally be expected with an SMC issue.
The magsafe charger is showing a green LED.
The macbook doesn't detect the battery at all, it is as if one isn't fitted and coconut battery displays 0 in all fields relating to the battery.
The battery does work once the device is running however it isn't possible to boot the laptop without the power cable. Even though the laptop is running normally on battery power once turned on, there is still no battery icon in the system tray. I've been unable to determine if the battery is being charged normally.
I've not seen this kind of error before and a search online doesn't provide any additional information.
Any advice you're able to offer would be appreciated.
Is this a good question?
