Mine always darkens, and it sometimes goes to ~%70, but other times it seems to go all the way down. Also, I've updated the BIOS and graphics drivers and the problem still occurs. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/789346 Title: Screen brighness randomly changes on Lenovo Y560 laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/789346/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I have a Lenovo Ideapad Y560 with an ATI Mobility Radeon HD 5730, and had the same problem. I have upgraded the BIOS to version 71 and the problem seems to be solved. I have downloaded the BIOS from the Lenovo driver download page specific to the Ideapad Y560 http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_list.aspx?CategoryID=661448 To avoid downloading a wrong BIOS, I recommend checking your laptop model going to http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers.html and filling the form with your laptop serial number.
