I appear to have broken my netbook.
Well, ‘broken’ might be a bit steep – it no longer responds to a lid close event with the nice, neat standby mode it once treated me to. Instead, it triggers the standby script and gets itself into a half-on, half-off state.
In this state, the power light is flashing to indicate that it’s in standby. Unfortunately, it isn’t – everything’s still working fine. The only indication that it even tried to standby is that my SD card unmount/remount script is triggered and the default keyring is locked.
