Hi, I noticed there's alway an 'Unable to dock' error message after suspend to RAM: PM: Saving platform NVS memory Disabling non-boot CPUs ... smpboot: CPU 1 is now offline smpboot: CPU 2 is now offline smpboot: CPU 3 is now offline Extended CMOS year: 2000 ACPI: Low-level resume complete PM: Restoring platform NVS memory Extended CMOS year: 2000 Enabling non-boot CPUs ... smpboot: Booting Node 0 Processor 1 APIC 0x1 Disabled fast string operations CPU1 is up smpboot: Booting Node 0 Processor 2 APIC 0x2 Disabled fast string operations CPU2 is up smpboot: Booting Node 0 Processor 3 APIC 0x3 Disabled fast string operations CPU3 is up ACPI: Waking up from system sleep state S3 ACPI: \_SB_.PCI0.LPC_.EC__.BAT1: docking ACPI: \_SB_.PCI0.LPC_.EC__.BAT1: Unable to dock! System info: ThinkPad X220, Linux 3.8.6 (ARCH), systemd 201-1, 1.4.1-5 I have tried to set Handle{SuspendKey,HibernateKey,LidSwitch} all to ignore, but I still get the same error message. Any other solution to make that message disappear? Regards.
