Standby mode for FC3

linuxmandrake · 08-06-2005, 05:11 AM

Where is the stand by mode in FC3. Like windows it has a standby mode which basically turned off the hardrives. If possible I would like the ram to be turned off as well because I heard it sucks alot of power. It has become more important for me because my machine now needs a 420W power supply which means it consumes more power.

To activate suspend-to-disk:

Code:

echo 4 > /proc/acpi/sleep

This will save the contents of RAM to disk and powerdown completely. It's the equivalent of what Windows calls hibernation.

For your information, just because you have a 420W power supply doesn't mean that it consumes that much - it just means that it is capable of supplying that amount of power. If you suspended to memory (what Windows calls standby), the power drawn will only be a few watts as the memory will only draw a few milliamps.

didn't work for me I think i have non standard ACPI

Did it do anything at all or did it not work? If your computer is oldish then it may not support ACPI but most modern computers should. If not, then you may have to use APM (Advanced Power Management) instead - which is the predecessor to ACPI.

It's worth noting that you may have to fiddle to get it to work - I'm using FC4 and I haven't yet managed to get suspend to memory to work yet - it reboots instead of resuming.

It sounds like it's having problems stopping a service or driver. I found that I had to stop various things, notably the HSF modem drivers, before I could suspend.
