To follow up on this old post which I just solved today:<div><br></div><div>It turned out to be a BIOS issue. This unit is the same as the Acer Aspire One 532H, so I grabbed the latest BIOS from Acer (1.25, it came with 1.10), and installed it with fingers crossed. The issues seem to have gone away. Hope someone else finds this useful.<br>

I'd suggest running "udevadm monitor" and watching dmesg while this is<br>
happening. If you can catch it when the battery goes away, that would<br>
be great, but you can probably look back through dmesg and deduce the<br>
messages from when that happened.<br>
<br>
Does the device show up in the udev output when you do 'cat<br>
/proc/acpi/battery/BAT0/state'? If so, it certainly seems like the<br>
kernel is sending spurious uevents to remove the device. Either way,<br>
this would seem to be a kernel bug. I would get the dmesg output and<br>
either open a bug at <a href="http://bugzilla.kernel.org" target="_blank">bugzilla.kernel.org</a> assigned to the ACPI product<br>
or send a meesage to <a href="mailto:acpi-support@lists.sourceforge.net">acpi-support@lists.sourceforge.net</a>.<br>
<br>
Good luck.<br>
