F16 on Lenovo x120e - cannot resume out of suspend mode

[Robert Moskowitz]

This started last friday.  Basically if I suspend the system comes up 
but no video and no keyboard response.  Power switch off does not seem 
to work, I have to pull AC and battery and I hear the drive stop.

This started when I had some runaway tasks that were eating up all my 
CPU (only single core model) so I was switching to terminal 2 
<ctl-alt-sft-F2>, running top, figuring out what might be going crazy, 
switching back to terminal 1 and stopping programs. After about 5 of 
these switchs, no switching back to terminal 1 and reboot and poweroff 
did not do anything (actually no keyboard response).  I ended up pulling 
the battery.  Since then suspend has stopped working right; don't know 
if they are related.

This evening, I powered up, applied all updates, powered down, powered 
up, powered down, powered up, THEN tried suspend and no dice still.

I WAS traveling and thursday, the notebook was in my backback on a 9 
hour drive, but not particularly bounced around.  It came out of suspend 
just fine friday morning.  Or so it seemed.

Advice for trouble shooting?  I really don't want to reinstall Fedora, I 
was hoping to wait until F18 for the next OS install.
