I confirm this battery drain occurs when the Sleekbook is turned off, not suspended. For the doubters, how do you explain the difference between Win7 and Unbuntu 12.10? I can actually use Win7 as a work around, work in Ubuntu power down, boot into Win 7 and then power down and I have a battery drain of 1.3% per day and not 17% per day as with Ubuntu. If I leave the Sleekbook for a week having powered down with Ubuntu I have a dead laptop. Makes a nonsense of the 7 - 8 hrs battery life I bought the sleekbook for. The Sleekbook has the battery embeded in the Laptop case and is not user removable. I will risk my warranty and take the Sleekbook apart to test the battery depletion with the battery disconnected.
For background, this bug is in support of the following 2 Ubuntu User forum Posts: http://ubuntuforums.org/showthread.php?t=2052582 http://ubuntuforums.org/showthread.php?t=2072741 The HP Sleekbook is a cut down Ultrabook, I noted Win7 has some HP advanced Power controls, is it possible there is a newer ACPI interface and Ubuntu leaves certain motherboard device power interfaces in an incorrect state? Is there anything in the attached logs? I did a suspend and resume at the end of the Kernel log (17:06.04). There were 4 ACPI errors on resume: Jan 11 17:06:04 dave-HP-ENVY-6-Notebook-PC kernel: [ 3603.783518] ACPI Error: No handler for Region [RCM0] (ffff88019665cea0) [SystemCMOS] (20120320/evregion-376) Jan 11 17:06:04 dave-HP-ENVY-6-Notebook-PC kernel: [ 3603.783525] ACPI Error: Region SystemCMOS (ID=5) has no handler (20120320/exfldio-306) Jan 11 17:06:04 dave-HP-ENVY-6-Notebook-PC kernel: [ 3603.783530] ACPI Error: Method parse/execution failed [\_SB_.WMID.ESDT] (Node ffff880196668d48), AE_NOT_EXIST (20120320/psparse-536) Jan 11 17:06:04 dave-HP-ENVY-6-Notebook-PC kernel: [ 3603.783540] ACPI Error: Method parse/execution failed [\_PTS] (Node ffff880196652bb8), AE_NOT_EXIST (20120320/psparse-536) What about this: Jan 11 17:06:04 dave-HP-ENVY-6-Notebook-PC kernel: [ 3603.923940] [Firmware Bug]: cpu 1, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098697 Title: High Battery discharge rate when Laptop is off.
