I use acpi to suspend when I close my laptop's lid. Usually this works fine, but if I first unplug the charger, and then try to suspend this way, nothing happens (it still works properly manually). When I plug the charger back, the system suspends almost immediately (if I suspended it manually, it suspends again after plugging in the charger). The same happens with hibernating.
If I close the lid multiple times while the laptop is not on the charger, then it will suspend multiple times (the same number of times as the lid was closed) while on the charger.
This problem does not appear when I first suspend the laptop, and then pull out the charger.

dmesg:

UPDATE:
acpid fails to stop while on battery (using rc-service acpid stop), but after I put the laptop back on the charger, acpid doesn't appear to be running.
If I first stop acpid, then unplug the charger, and after that start acpid, suspending still doesn't work (but the laptop will suspend once on the charger again).
