           Summary: Lid switch correct every other time;  suspend every
                    other lid close; Samsung N150-11 netbook
           Product: ACPI
           Version: 2.5
    Kernel Version: 2.6.35
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: EC
        AssignedTo: acpi_ec at kernel-bugs.osdl.org
        ReportedBy: linuxkbt.9.eeeeeee at xoxy.net
        Regression: No


Samsung N150-11 netbook. Each lid close&open toggles the lid switch state 
so when the lid is open, half the time it reports closed:

e at eSammy:~$ cat /proc/acpi/button/lid/LID0/state
state:      open

# close & open lid

e at eSammy:~$ cat /proc/acpi/button/lid/LID0/state
state:      closed

So, the netbook only suspends every other time the lid is closed.
This could be dangerous with the netbook stowed in running mode
draining battery and getting hot.
