Hi. I'm a newbie to linux, but I've been getting this problem ever since I installed it on my computer (I've already tested Fedora Core 5 and Ubuntu 6, both having the same problem). 1) I first discovered that my laptop display didn't turn off when the lid was closed (I can tell because I can see the glare of the display through a gap). So I started investigating and found that the lid event is not triggered whenever I close/open the lid (using acpi_listen). But the weirdest part is that the event is reported when doing "cat /proc/acpi/button/lid/LID /state". 2) Then I realized no events are reported through acpi_listen, except for "ac_adapter" event which occurs after resuming the laptop from hibernation. 3) I've also found that sometimes the computer freezes when resuming from hibernation (I can only confirm this under Ubuntu, I can't remember what happens with Fedora). 4) Finally, for some reason gnome power manager doesn't put into hibernation my computer when battery is too low (the only time I tested this was under Ubuntu) and simply runs out of battery. Since #'s 1 & 2 have ocurred under Fedora and Ubuntu, I assume there is some low level problem/incompatibility of ACPI with my computer's hardware. Everything works fine under WinXP, and to me power management is a must for my laptop. I've read some stuff about DST's, but sincerelly I didn't undestand much (ie. where does this DST reside? Is it a firmware?), but I wonder if the fact that my DST says "MSFT" could be the cause of ACPI not working propertly. Thanks in advance. - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
