JPedro, as per http://download.lenovo.com/express/ddfm.html an update is
available for your BIOS (1.52). If you update to this following
https://help.ubuntu.com/community/BiosUpdate , does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

Title:
  Dropping WLAN connection every 7-10 minutes

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Kern.log says this

  May  2 23:52:29 jpt-ThinkPad-SL410 kernel: [ 2040.220779] wlan0:
  deauthenticating from ca:6c:87:ab:dc:2c by local choice (reason=3)

  And then continues to associate again with the AP, I have seen
  suggestions that power off for interface powermanagment was a working
  work around, but it does not work in my case. And the earlier bug
  report was closed with a resolved status.

  I did not have this issue before upgrading to 12.04 and the 12.04
  installation is a clean one, SSD was formated etc, before installing
  ie not an upgrade from 11.10.
