Test8 suspend fails if laptop lid closed.

Test8 suspend fails if laptop lid closed.

[Rob Landley]

Interesting.  Suspend to disk (echo -n disk > /sys/power/state) works just 
fine as long as I keep the laptop open until it powers down.  (I timed it, it 
takes 35 seconds by the way.  Over half of this is "freeing memory" without 
the hard drive light actually going...)

If I close the lid while it's busy suspend, it won't.  It'll almost suspend, 
but the CPU power will stay on, the fan will stay running, and the backlight 
will stay on even though the screen is otherwise black.  Only thing to do 
then is hold the power button down for ten seconds until it fully powers off, 
then reboot it.

It works reliably so far if I leave the lid open, and fails reliably with the 
lid closed before it's actually done suspending.  This is on a thinkpad 
iSeries 1200 something.  (Serial number starting with 1171 6xu, from which 
the model number can be googled for if it matters...)

Any ideas?

Rob

A couple of us have seen the same thing under 2.4. I've found a hack
solution for my laptop, but need to investigate more. It certainly looks
like an ACPI problem from here.

Provided he's actually using ACPI. My laptop will halt the processor and
enter a sort of stanby state if when legacy (APM) mode and the lid is 
closed.
