Hi. I have a Lenovo G50-30 and am also having this problem. Not sure how this whole thing works and if I'm supposed to comment on here, so apologies is if this is in the wrong place!
The output of sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date for me was A7CN25WW 04/28/2014 These are the details of my laptop: Lenovo G50-30 15.6-inch Laptop (Black) - (Intel Pentium N3530 2.16 GHz, 8 GB RAM, 1 TB HDD, Integrated Graphics, DVDRW, HDMI, Camera, Wi-Fi, Bluetooth, Windows 8.1) I have downloaded the following files: linux-headers-4.7.0-040700rc7_4.7.0-040700rc7.201607110032_all.deb linux-headers-4.7.0-040700rc7-generic_4.7.0-040700rc7.201607110032_amd64.deb linux-headers-4.7.0-040700rc7-lowlatency_4.7.0-040700rc7.201607110032_amd64.deb linux-image-4.7.0-040700rc7-generic_4.7.0-040700rc7.201607110032_amd64.deb linux-image-4.7.0-040700rc7-lowlatency_4.7.0-040700rc7.201607110032_amd64.deb And booting with the generic kernel appears to have solved the problem for me. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1574047 Title: Lenovo G50-30 laptop freezes randomly Status in linux package in Ubuntu: Incomplete Bug description: Keyboard or mouse do not work when the system freezes.
