Curious "sleep" experience

[Timothy Murphy]

When I first installed Fedora-18/KDE
sleep didn't work at all - on waking my laptop
(Thinkpad T61 with AMD/ATI M52 [Mobility Radeon X1300])
it just flashed every second or so, and I had to re-boot.

Now it works fine, but with one curious feature.
When I press the power button the laptop seems to be waking,
but then goes back to sleep.
When I press the power button a second time it wakes properly.

This doesn't worry me, as it only takes a couple of seconds in 
all.
But I'm slightly puzzled by it,
and wondered if mine is a general experience?

Simply turning the computer on, should wake from hibernate.  The
computer wills /start/ to boot in the normal way, but at the very start
of the booting process, Linux will check whether it should be resuming,
and resume if it can.  It boots up using a memory dump in the swap
partition.  (When you sent the computer to sleep, beforehand, the memory
was dumped to the swap partition.  When hibernated, the computer can be
completely powered off.)

How you turn the computer on will depend on your computer.  If, when
suspending, it keeps the keyboard power running, and the BIOS is set to
wake up on keyboard events, merely pressing a key should do it.  Other
events can be used to wake up the computer, such as mouse presses.  But,
if no wake events are configured, simply turning on the power will do.

Suspending, on the other hand, does its resume from what's held in RAM.
So the RAM needs power while suspended.  And, I suspect, dynamic RAM
should need the motherboard to keep it refreshed.  So the motherboard
needs to be kept powered, and in a special suspend mode.  If power is
lost, the next wakeup will be a normal boot.  To resume from the suspend
mode, the computer does need some way for you to send a wake signal.  As
before, usually the keyboard.  It's possible that a soft power switch
may wake it up, but it's also possible that pressing it mayn't help.

Have a look through all of your BIOS options for wake configurations,
suspend options, and other power management settings.

I have never known how to wake from either the wake or hibernate commands.

I too have the same issue.  And I know at least one other person with
the issue.

I have not filed a bug report yet solely because I have no clue how to
single out the faulty package here.  One thing to note, I see that all
known cases are ThinkPads.

Hope this helps,

Open source is the future. It sets us free.

In my case witch is an HP Probook 4515s - it has also flaws with sleep
hibernate. When it wakes up, the ventillation switching to maximum,
and can't be stopped. I tried to fix with quirks but no use.

@Timothy: I think your machine also needs an extra quirk setting -
when I had experienced similar when I had Fujitsu the symptomes were
the same that you described. Surely needs an bugzilla ticket.
