I’ve been having some serious difficulty with my laptop and using suspend to RAM. Suspend to disk is another issue, with similar symptoms. This is pretty regular for a Linux laptop. In many of these cases, the cause of the problem is a hardware vendor’s poor implementation of the ACPI. I’ve checked and I am already using the current version of the BIOS.
