MBP Not Detecting Battery
After replacing the faulty speakers of my MBP in-line with the iFixit guide, the device stopped detecting the battery. At login, the battery icon shows 0% for a couple of seconds, then shows an “X” icon. Also, System Report does not identify the battery.
I have tried removing and re-connecting the battery, and both SMC and NVRAM.PRAM were reset, but to no avail. The laptop works fine with the power cord, sometimes slightly laggy.
All was working fine prior to the speakers replacement.
Any help would be greatly appreciated. Thank you.
