If I disconnect power of my laptop and have the lid closed, it goes to sleep/hibernate immediately (while battery is fully charged)

If I disconnect power of my laptop and have the lid closed, it goes to sleep/hibernate immediately (while battery is fully charged).

If I disconnect power only the laptop works good on a battery, but if I close a lid notebook goes to sleep.
It's a problem in acpi, I suppose.

In syslog I see:

Btw, after restoring from sleep power button indicator remains red (like in deep sleep mode/hibernate).

I use LinuxMint 12 (with up-to-date soft).

The problem occurs seldom.
usually after unplugging power source and losing a lid I get only these messages in syslog:
"Jun 30 15:18:21 localhost kernel: [21860.256536] EXT4-fs (sda6): re-mounted. Opts: errors=remount-ro,commit=600

Does this bug apply to any of the currently supported releases (i.e. Maya, Nadia, Olivia, or Petra)? If not, this bug should be closed.

[drey (inhuman-irk)]

not important already.
updated both my notebooks to LM15 and have no such behaviour.

[chemicalfan (mike-lumsden)]

FYI - Mint 15 isn't supported anymore, so you should consider upgrading to 16 (unless you're happy to wait for 17 LTS, but you won't have any security updates until then)
