I have exactly the same issue as the original poster, also on an Acer Aspire Timeline 3810TZ, but using Ubuntu 10.04 (beta). Even with the latest BIOS from Acer/Inspyre (revision 1.24), the symptoms are the same: On resume, the machine spins up for a few seconds with the screen remaining dark, then switches off completely. Although I'm not the original poster, I will attach the information from apport-collect as instructed.
