Description

Hi,

Over the last week I've had three machines brought over to me in the following state:

  • screen is off
  • power light is solidly on
  • no response to keyboard or power button

We got through to one machine in this state via serial, and managed to pull a dmesg. It's an MP machine running a joyride build from today (1689), with up to date OFW too. One pertinent section is:

Chris,

it seems like the module is going completely dead since it doesn't seem to respond to its reset line been toggled via the EC.

Next time you get a machine in that state, I would really like to check the wireless module's supply voltage.
