Q: Battery Fried From Plane Ride (It even rhymes!)
Hey all,
I have a problem with my battery. Everything was working fine until about a month ago. I took my laptop on the plane with me and once I landed it started acting strangely. Initial problems:
1. The battery seemed to drain incredibly quickly;
2. The battery would jump down percentages. For example. It would show 55% then jump to 35%.
3. Once under half way, the computer could just turn off, regardless of the battery percentage shown.
That continued for a few weeks but it got worse to the point where, if unplugged, the computer could turn off at almost any point randomly. A few days ago, the laptop started turning off if the power source was removed, even for a split second. I have just looked at the hardware and I get this readout:

After looking through these forums, I tried an SMC reset. Until then, the battery showed it was 100% fully charged the entire time. Since doing the SMC reset, the battery went to 0% and is now charging. However, it still shows in that readout that the battery is not charging and that it is fully charged so I'm a little confused. The computer is out of warranty so it would be great to get an idea of what could have happened on a plane ride that could have caused this? Can altitude or the scanners fry the battery somehow?
Thanks heaps!
