Thank you for the detailed response. It is incredibly helpful. I am still working on gathering information. I have 4GB RAM. It is good that you have the exact same PC, so you may be able to duplicate my issue. I can report so far that when on battery the computer suspends and awakens as it should after one minute and after 15 minutes. I used the power button to put it to sleep and the Enter key to awaken it. There was nothing in the resume log after the start time. There were two lines highlighted in red. Does that mean something abnormal?
Next, I suspended the PC by closing the lid and tried to resume after 30 minutes. After the IRQ lines, the screen went blank, and I could not get to the desktop. When I pressed Ctrl-Alt-F2 I received a text output (terminal, I guess), with the Ubuntu disclaimers and a Linux Lite welcome, with the date, memory usage, etc. The prompt was strange, myname diamond ~ diamond.
I ran the resume process as you suggested and found several errors at the time I tried to resume. I was able to create the txt file and will try to send it to you. I must be missing something because I cannot find any way to attach the file to this reply.
One thing to note, when I installed Linux Lite, I had no battery in the PC because the old one was completely dead. After the installation and when everything seemed OK, I bought a new battery and am now using it. Could the OS not be recognizing the power source correctly?
Also, I still get an error message when I try to hibernate instead of suspend. Hopefully the resume log file will provide some answers to that as well.
Thank you again. I will post another reply when I figure out how to upload the resume log.
