Dead battery on rev C MBA?

[masterpace]

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.

hm, i thought amber meant it was in "charging mode"


try this:

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).

1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.
