If you can, look at the /sys for bq27000 idea of temperature and current.

I can't see an easy way.

WLAN can't be disconnected from power, and the device won't stay up
without a battery typically.

What I would suggest is update to something using the newer kernel and
see if it still happens.  One of the changes in the newer kernels is
overhaul of the WLAN driver.

In git anyway the packaging config for the kernel has WLAN stuff as
modules, and when you rmmod the module it should take the device down to
its lowest power state.  So that should give a way to try to point the
finger anyway.
