Samsung N145 plus acpidump file
As asked for by Lan Tianyu.
Boot netbook:
cat /proc/acpi/button/lid/LID0/state -> OPEN
Close lid, notebook goes to sleep.
Open lid, notebook wakes up, but:
cat /proc/acpi/button/lid/LID0/state -> CLOSED
I have to shut lid, then re-open again to get lid state to report OPEN.
I do have a modified dsdt (it's not right, but not wrong either!) that gets
around the issue sort off, but it appears to me that the method:
Method (_Q5E, 0, NotSerialized) // _Qxx: EC Query
{
Store (LIDS, \LIDS)
Notify (\_SB.LID0, 0x80)
}
isn't working, i.e. a hardware fault, in which case nothing can be done... but
here's hoping.
I have attached acpidump from kernel 3.11.5 built on Slackware 14 base, no
modules, all built in.
I also have my current changes to the dsdt file (with notes and a diff) here:

to provide further info.
