I can confirm on dell xps 1530 with nvidia 8600m GT, lucid and 256 series driver.
This just happen with an external monitor attached, powermizer is locked to performance level 2 and cpu quickly geoes to 90 degress. As in comment #59. Disabling the external monitor, I get back to situation you see in the screenshot attached and cpu gets cooler. just in case, monitor is attached with VGA cable. ** Attachment added: "nvidia-powermizer.png" http://launchpadlibrarian.net/51327866/nvidia-powermizer.png -- laptop overheats and suddenly shuts down/off https://bugs.launchpad.net/bugs/370173 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
