What system and what do you mean by "powered down"? How much time does it take for the battery to drain now? > The bisect actually pointed to commit de3ef1e, but reverting > these two commits fixes the issue. > > I was hoping to get your feedback, since you are the patch author.

First, reverting these is not an option or you will break systems relying on them now. 4.13 is three releases back at this point. Second, your issue appears to be related to the suspend/shutdown path whereas commit 0ce3fcaff929 is mostly about resume, so presumably the change in pci_enable_wake() causes the problem to happen. Can you try to revert this one alone and see if that helps? -- 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/1745646 Title: Battery drains when laptop is off (shutdown) Status in Linux: Unknown Status in acpi package in Ubuntu: Confirmed Status in linux package in Ubuntu: In Progress Status in acpi source package in Artful: New Status in linux source package in Artful: In Progress Bug description: I am using hp AY008tx laptop , and many other laptop users (HP) are also facing the same issue .
