[ltp] SOLVED: APM not waking up after prolonged sleep to RAM

[Bob Alexander]

As many of you might have read with both 2.6.9 and 2.6.10 kernels and 
APM, my Thinkpad T40 (2373-92G) did not resume after being left in 
suspend to RAM for a longish time (very approx. over 45 min).

Shorter sleeps went just fine and the machine restarted just perfectly 
with it's brilliant GNOME desktop and X.

The solution was found in a BIOS setting.

In the config->power section, towards the bottom, there was a setting 
which sounds like "Hibernate after suspend expires -> Enabled". I just 
put this as Disabled and my TP woke up this morning like a young 6 years 
old on Sunday morning :)

I'm happy :)

The power consumption is very good.

This is quite logical since something must have happened between a short 
and long sleep. It was this suspend timer expiring.

Now I hopw this info will help people more kernel knowledgeble than me 
to fix this once for all.

Peace and happiness to all,
Bob
