First, please build your kernel with CONFIG_ACPI_DEBUG set, and uncomment line 30, i.e. "/* #define DEBUG */", in drivers/acpi/ec.c, and then run echo core > /sys/power/pm_test echo mem > /sys/power/state in the new kernel, and attach the dmesg output after this test. > Oh, just for the record, my wife has a subsequent model of this notebook (it's > a notebook that her workplace has allowed her to use) and *that* computer > sleeps without any problems. > what's the model name of this notebook? do they share the same BIOS image? can you check if there is any BIOS update for your laptop? > BTW, after further use of this notebook, I have discovered many other > power-related quirks.
