Hi! Last night, I turned on my rev C MBA using the battery power. It booted properly but soon after I logged in, my MBA suddenly went off (as if I holded the power button for a few seconds). Then, I've decided to power cycle it. Still the same thing: it shut downs unexpectedly. The moment it shuts down is quite random, but I cannot use the Air on battery for more than a few minutes (less than 5 minutes actually).

Hence, I decided to charge it overnight. This morning, to my surprise, the charging light on the adapter was amber (not green). So, it seems like I cannot recharge my battery. I've reset the PMU and this doesn't help. Please note that I haven't used the MBA for a few weeks, leaving it unplugged. I don't know whether it had some impact or not on the battery.

I'm thinking of sending the unit for repair (still under warranty). Do you think my battery is dead? Which other tests should I do? Any input would be appreciated. Thanks in advance.

You're right, as the issue is almost certainly your battery. In the old days of removable batteries, this problem was a lot more common; then again, you could just remove the battery to temporarily resolve the issue. These days, you'll need to have Apple or an Apple Authorized Service Provider replace your battery, and it would definitely be covered under warranty as long as the battery hasn't been cycled so much that it's worn out.

If you'd like, and if your MBA will stay on this long, you can check how many charge cycles the battery's had by opening "About This Mac" under the Apple menu, clicking "More Info," navigating to "Power" in the left sidebar, and finding "Cycle count." If it's under 300 cycles and your computer is less than a year old (or under three years when covered by AppleCare), your battery replacement will be free.

Or you can remove the bottom panel and just unplug the battery until you can get a new one or whatnot... doesn't take a genius
