New battery very slow charging
I replaced the battery of my mid-2010 MacBook Pro 15". It takes ages to charge, "20:00 until full". System Information shows a charge rate of 288mA.
I once got it to charge at a better rate, by draining the battery completely until the system shut off and then charging. Charge rate was around 5000mA, after this charge cycle, it's back to the old slow charging.
I already tried NVRAM and SMC resets, but those don't help.
Es esta una buena pregunta?
