Dell optiplex 740-power save S3 in linux don't work properly
Hi,
I have problem with power save S3 in any linux distro .
In win xp it worked fine.
In linux it goes to S3 mode good, keyboard is off , screen is black, after 2 min Power button blinking.. Computer is in " suspend to ram" mode.
When I press Power button computer awakes. But keyboard is off and screen is black..
I use linux such as ubuntu, MX,Fedora,Sparky,Siducuction,Sparky, ... in live mode. In every distro I can't awake keyboard and screen.
I think that BIOS is a little poor in power save mode ,but anyway in win xp it worked fine.
Thanks for any help.
