Sorry, thought I was replying to the list too. Maybe this could be relevant to others who'll likely have the same issues, hope that's ok. ---------- Forwarded message ---------- Date: Sun, 16 Jun 2013 01:55:14 +1000 (EST) From: Ian Smith <smithi@nimnet.asn.au> To: Joseph Mingrone <jrm@ftfl.ca> Subject: Re: Lenovo T530 - Battery Warnings On Sat, 15 Jun 2013 12:03:14 -0300, Joseph Mingrone wrote: > Ian Smith <smithi@nimnet.asn.au> writes: > > > On Sat, 15 Jun 2013 11:10:52 -0300, Joseph Mingrone wrote: > > > Ian Smith <smithi@nimnet.asn.au> writes: > > > > if '# kldload speaker && spkrtest' makes useful noises on the > > > > speaker... > > > > > > Maybe this is the source of the problem.

Right; there's been quite a lot about this issue in freebsd-acpi for the last year and more, and various Lenovo *530 have come up (Y530 & E530). The bottom line seems to be that you need to patch acpi_ibm, or run stable/9 to pick up the patched version. I suggest browsing the acpi@ archives esp. for thread: "what is required to support a new laptop?" which highlights some differences between [45]20 and 530 series; I'm not sure anything I can find on a T500 is likely to help, but I'll see. A lot of the above is folks trying to get brightness controls working, but maybe if you get acpi_ibm loaded and functional it may help this? cheers (and out for now, Ian
