I wonder if it was an issue with your X display manager (gdm, kdm, etc.).

For me I had a similar issue. When not logged in my laptop would go to 
standby after 20 minutes.

I managed to fix it by adjusting GDM settings.

Too late for your purposes, since you have a working hardware solution.

But there is a software only fix:

(I work on display drivers for another common OS, and this is a common 
problem)
