Dear Christopher, Thank you for pointing out outdated BIOS. I upgraded my BIOS to the latest version.
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date output is: L70 Ver. 01.07 01/10/2014 However, I can not tell more about lock ups because of problems with nvidia-settings - no options are showed when I open Nvidia X Serves Settings ( please see attached screenshot or link here - https://dl.dropboxusercontent.com/u/4795668/Screen.jpg) It seems like nvidia driver is installed (331, tested) but problem with nvidia settings does not allow me to switch between nvidia/intel and test whether BIOS update helped or not. I didn't have lock ups while working on intel card. Also tried to install prime-indicator package to switch between cards, but it doesn't seem to work with latest updates in ubuntu 14.04 (tried to uninstall/reinstall - didn't help) - application doesn't load. I have the latest Ubuntu 14.04 updates installed (checked just before comment submission). Is there any other information I can provide to help with this issue? Kind regards, Iaroslav ** Attachment added: "Screenshot with nvidia settings" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310762/+attachment/4101146/+files/Screen.jpg -- 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/1310762 Title: [HP ZBook 15 Mobile Workstation] Ubuntu 14.04 random freeze and lock up Status in “linux” package in Ubuntu: Incomplete Bug description: Just upgraded to 14.04 and started to experience random freezes. Only workaround in to ctrl+alt+tab+F2 and ctrl+alt+tab+f7 to unfreeze laptop. Or hard reset. Currently happens when browser is open (occures for firefox, chromium). Switching from nouveau to nvidia proprietary drivers (tried both stable and updated version) didn't help. Is there any other information I can provide to help track and resolve this bug?
