Yesterday, I attempted to test the ACPI power saving modes available on
my system. After entering super-user mode and entering the commands 'cd
/sys/power; echo -n "standby" > state' my machine proceeded to enter
some kind of strange, non-functional "standby" mode wherein all the
peripherals, devices, cards, and fans remained unaffected -- all that
happened, from my perspective, was the OS locking up with the display
still on and unchanged and the system power LED proceeding to blink. I
attempted to restore my machine to a functional state by pressing the
power button, as is the normal procedure when one's system indicates it
is in standby by causing the power LED to blink. This stopped the LED
from blinking, but failed to un-lock the OS. I was able to enter the
RSEIUB key sequence though, upon which I caused a successful reboot.
When my system entered the stage wherein the BIOS would normally check
for a bootable USB mass storage device and boot off said device, my
system instead entered the PXE boot process which eventually failed with
the proverbial "INVALID SYSTEM DISK OR DISK ERROR". After this, I booted
- off the Kubuntu install CD from which i performed a filesystem check on
+ off the Kubuntu install CD from which I performed a filesystem check on
the external USB drive. No errors were reported, so I reinstalled GRUB
for kicks, rebooted, and lo and behold everything was fine again.
My operating system information follows :
OS : Kubuntu 8.04 Linux
Kernel : ( uname -a ) jdb2-Kubuntu-temp 2.6.24-19-generic #1 SMP Wed Aug
20 22:56:21 UTC 2008 i686 GNU/Linux
"lsb_release -rd" output :
Description: Ubuntu 8.04.1
