And another strange thing. I tried to install latest Ubuntu (built September, 2), and successfully boot into it. However, strange things were happening during the boot: screen just switched off 15-20 seconds. But finally i was able to log in to the system. The only thing I did - connected to WiFi, then tried to reboot laptop and it freezed during shutdown.
Unfortunatelly, consequential reboots resulted to an error (see attachment). P.S. I used Windows between first successfull and next failed Ubuntu's boots. ** Attachment added: "Kernel null pointer dereference error" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1615361/+attachment/4733131/+files/IMAG1929.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615361 Title: Ubuntu 16.04 fails to boot on HP Envy 15-ah150sa laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1615361/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
