By sleep of death I mean that there is disk activity, cpu goes into hi gear, 
then the run led shuts down, the sleep led comes on and nothing works except 
holding down the power button until the system shuts down.  This happened when 
I first loaded 9.10 from the DVD in the magazine Ubuntu User.  So I tried it 
with the CD from UDS-L and got the same behaviour.  So I tried the Kubuntu 9.10 
from UDS-L and it ran fine except it took Jonathan Riddle 1/2 an hour to get on 
the WiFi there.  When I shut down another developer spent over a 1/2 hour and 
could not get Kubuntu 9.10 to connect to the WiFi again although he was looking 
at the ./bash_history of the previous success.  The kernel team told me there 
was a fix in 
https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume
or 
https://wiki.ubuntu.com/DebuggingKernelSuspend
so I went to both places but could not solve the problem.

Next I did a search in Launchpad and found about 90 things marked
"solved" for this problem.  After too much wasted time I found one that
said "poke around in" url....  The user said thanks, I solved it and he
did not mention anything about how he solved.  This struck me as the
very poor communication which I see so often which seems to me to be the
greatest problem holding back the adoption of Linux.

So I went back to 8.04 to get some urgent things done.  At night, I
again loaded the 32 bit 9.10 from Ubuntu User.  Then I loaded the
kubuntu-desktop.  Then I upgraded kubuntu and ubuntu.

The problem still occurs only in Ubuntu 9.10 not in Kubuntu 9.10.  It
also happens when the only window I have open in Gnome is the terminal
and I disconnect the power adapter.  I also rebooted without the power
adaptor.  As soon as I plugged the power adaptor in I again got the
sleep of death.

Another thing I did was change all of the Gnome settings so that it
would suspend everything to disk rather than ram.  But this did not
really make much difference other than it took longer to sleep into
death.  Sometimes when I hit the power button briefly in an effort to
resume, I will see activity on the hard disk and I nearly always
remember the cpu changing from 800 to 1.6 Ghz.

My laptop computer is from China.  I bought it in June 2006 from Fry's
with a 5 year replacement guarantee.  But Fry's makes excuses instead of
honoring their $199 extended warranty.  It is an AMD Turion 64 with ATI
graphics and Rt2500pci wifi.  It may have been made from the same place
that made Compaq.  The female plug accepting the power adapter is worn
out so it switches from power to battery with every breath on or
movement of the power cord.  This caused the last half of my UDS-L
session to be without a computer since I was running Gnome because I
really dislike every package having to be something new and special that
must begin with the letter K instead of using what was proven many years
ago and continually improved since them.

Any help you give will be appreciated and with proper communications
will likely help many in the third world who cannot buy a new laptop
every 2 or 3 years.

9.10 goes into a sleep of death whenever power switches to battery.
