Unrecognized battery after HDD and RAM upgrade
After everything done, following your guide. The mac is working properly, except for the battery, that is working, as i can sometimes turn on the mac, with a loud fan noise on battery mode.
With AC power connected it runs good, but there's a cross on the battery indicator, indicating that there no battery.
How can i solve this? what steps should i follow exactly to make my battery recognizable again?
(tried already some solutions, on plugging/unplugging the battery connector with and without AC power plugged in)
Thanks in Advance
Is this a good question?
