Re: [Question #76712]: Suspend (to RAM) missing

 

Question #76712 on Ubuntu changed:
https://answers.launchpad.net/ubuntu/+question/76712

Derek White proposed the following answer:
Open a terminal: Applications > Accessories > Terminal & enter:
acpi_available   [it should output nothing]
echo $?

The result is as follows:
0 (true)       ACPI subsystem is available
1 (false)      ACPI subsystem is not available
2              usage error (arguments supplied)

If that returns true, you have acpi installed and available.

UnderstandingSuspend link near the top.
