X in battery icon in menu bar. What's up with that?
On the above machine, now I get an X in the battery icon instead of an outlet or thunderbolt. I tried another battery on it. The swap showed the thunderbolt for a little while and then went back to the X.
I don't think that it is the battery since it happened to two batteries at the same time. My guess is that it could be the DC to DC board. BTW, the power adapter is glowing green.
Any suggestions to fix this problem?
