With this configuration and kernel 2.6.20-16 I'm able use both suspend and hibernate. HOWEVER, there are major problems with both of them. Unfortunately, the problems are not easily reproducible, and usually it takes long time to run a test, which is not a luxury I can afford. This is also the reason I haven't reported them yet.
Suspend-to-RAM:
- works, but you can never be sure the laptop is going to resume normally or perform standard boot on attempt to return from standby. In this respect, the symptoms are just like described by Peter Funk above, only that for me it happens approx. 1/3 of the time. Usually the laptop would suspend and resume ok if left in suspended state for relatively short time, like a couple of hours. If left overnight, there's 9/10 probability that it would boot up instead of resuming.
Hibernate:
- works *somewhat*. Sometimes I get "HAL failed to hibernate" popup message on return from hibernation. Some other times the system is distinctly sluggish on return, feels like running on half the CPU power. In both situations reboot helps restore the functionality.
Actually I currently have different configuration for acpi, which is a result of many trial-and-errors. Please see below:
ACPI_SLEEP=true WHITELIST= "" /var/lib/ acpi-support/ vbestate PCI_STATE= true MODE=platform "mysql psmouse bluetooth cupsys" LAPTOP_ MODE=true
ACPI_HIBERNATE=true
ACPI_SLEEP_MODE=mem

I also have latest BIOS from HP (I believe it is version F.1A). http:// h20000. www2.hp. com/bizsupport/ TechSupport/ SoftwareIndex. jsp?lang= en&cc=us& prodNameId= 1839862& prodTypeId= 321957& prodSeriesId= 1839859& swLang= 8&taskId= 135&swEnvOID= 1093
