Here are the files. System woke up successfully from suspend for the first time. The second time, when I suspended, it didn't work; it just locked the screen. I unlocked the screen and suspended again and it worked this time. After it woke up, I shut down the system but it halted during the shut down and I restarted the system by pressing ctl-alt-del. I had experienced system halt during the shut down couple of times before. I copied the kernel log file and acpi directory after the restart. Thank you very much.
