What is ACPI?


I would like to know what is ACPI?
How does it affect me and what if I turn it off?
Does it make a difference for performance?

It's because I read on these forums that ACPI might not be something enabled on older computers. But I have a toshiba laptop that I bought a few months ago, so it should have it...

But I've only tried liveCD's so far, and they have only worked when I have ACPI turned off.
So, before I install it, I just wanted to be sre ACPI won't cause anything when I actually install them.

ACPI is the power management system. So if you want to be able to know what your battery status, use sleep/hibernate, etc in your laptop, you need to have it enabled.

I had to compile a 2.6.16 kernel to get mine working...

If you don't enable ACPI on a laptop the battery won't last for long.

I recommend building your own kernel and enabling Toshiba stuff under ACPI, whatever distro you choose.

Can I use ACPI to put a desktop system to sleep?
I have a G4 PPC with Fedora5 but it doesn't go to sleep when not in use. Any ideas?
