That message is totally normal and just means that your lid switch is being enabled to _wake_ the system. So if you suspend with 'zzz' or whatever, you can still wake via the lid. This can be disabled via a sysctl if you want. > Is there something else I can try? > > Dmesg, sysctl.acpi and acpidump are available at: > http://home.datacomm.ch/hampi/pavilion/ See if Linux works. In general, suspend/resume does not work on a lot of laptops including on Linux. The process for fixing it is simple: begin by auditing all device drivers and fixing their suspend/resume methods. Continue on to fix all X video drivers by getting the undocumented info from the manufacturers. As you can see, while simple, this is a lot of work. There are a few things we can do better (_SxD, D3 on suspend) and I'm working on those, but fixing 5.3 to be a stable release is much higher on the priority list right now. -- Nate
