bhaskar, as per http://www.dell.com/support/home/us/en/19/product-support/product/precision-m6600/drivers an update to your BIOS is available (A15). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Tags added: bios-outdated-a15 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Suspend puts laptop in state requiring hard power down + power up + [Dell Precision M6600] Suspend puts laptop in state requiring hard power down + power up -- 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/1315027 Title: [Dell Precision M6600] Suspend puts laptop in state requiring hard power down + power up Status in “linux” package in Ubuntu: Incomplete Bug description: At random (I estimate perhaps 20-25% of the time), when I suspend my Kubuntu 14.04 (upgraded from 13.10, not a fresh install) laptop, it blanks the screen, and displays a message such as that below on the text console. Then, instead of going to sleep, it remains powered up. In this state, nothing works to get back control, not Ctrl-Alt-Del, Ctrl-Alt-Backspace, Ctrl-Alt-F2 (or other function key), not ^C. The only way I have found to get control is to hold the power button down, which is a power-down and then power-up. Message on console is: [40066.396632] PM: Syncing filesystems ... done [40066.767832] PM: Preparing system for mem sleep [40066.768398] i2400m_usb 2-1.5:1.0: firmware i6050-fw-usb-1.5.sbcf: Cached [40066.768473] Freezing user space processes ...
