I think there is some mis-understanding here -
It **has to work** since it is at the very heart of the kernel's power management system.
Code:
[root@kindle root]# cd /sys/power
[root@kindle power]# ls -l
-rw-r--r--    1 root     root          4096 May 24 06:29 state
[root@kindle power]# cat state
standby mem
[root@kindle power]# echo mem > state
**dead** (almost completely)

Although the battery manager chip is still running (the 'charger') in this state it does not respond to "wake on USB" events.

All of the above while never disturbing the screen saver (or whatever was drawn last) on the display.

The only way out of this state is to reboot the device.
