I just observed a strange phenomenon on my new T42p (latest BIOS). I can successfully suspend and resume to and from S3 and S4! Kernel ist vanilla 2.6.11.8 using ACPI support scripts from the Ubuntu acpi-support package (removes critical modules, does vbe save and restore, etc...) So far very fine and indeed good work. Before suspend I usually see a power consumption of about 16W including WLAN, which is nicely low. But strangely after resume from either S3 or S4 I have see a power consumption of 19W+. This means ~3W more or in other words, roughly 20% less runtime. This is pretty annoying - not a real show-stoppper but it would be nicer without ;) I have no idea how to diagnose this. My first guess is that some devices are not resumed correctly but I have no real idea how for example gather device states before and after suspend, or other means to diagnose this. So, if anyone has an idea how I can diagnose this and help this issue to be solved, let me know. Or is there already a solution floating around? Thanks!
