Linux APM on Omnibook 6000

The Omnibook 6000 displays some strange power management quirks. By default the kernel is not correctly configured to allow you to suspend and resume. Other pages on the net described what to do to make it work.

For starters, ensure that your kernel is configured correctly. Either use my kernel configuration file directly, or ensure that the following parameters are set:
CONFIG_APM=y
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
CONFIG_APM_DO_ENABLE=y
# CONFIG_APM_CPU_IDLE is not set
# CONFIG_APM_DISPLAY_BLANK is not set
CONFIG_APM_IGNORE_MULTIPLE_SUSPEND=y
CONFIG_APM_IGNORE_SUSPEND_BOUNCE=y
# CONFIG_APM_RTC_IS_GMT is not set
CONFIG_APM_ALLOW_INTS=y
CONFIG_APM_REAL_MODE_POWER_OFF=y


Recompile your kernel from the /usr/src/linux directory and then copy the new kernel image from re-run lilo to install the Then, edit the /etc/sysconfig/apm file and uncomment the line CHANGEVT=7.

To suspend your machine, become root and type apm -s. The X display will disappear and you will be dropped into a text console. Some messages will scroll by and after a few seconds the machine will shut down. You will notice that the power light on the front of the machine turns yellow/orange, not green. The batteries will continue to charge if the power cord is attached.

To resume, hit the blue wakeup button above the keyboard. The disk will whirr and you'll see the text console appear. Some messages will scroll by as the machine wakes up. Hit Alt-F9 and you will be back into the X display.
