HP Recommended
Product: W2K28UA
Operating System: Linux

Summary is that the laptop immediately wakes up, unprompted, when put into S3, either using power button or closing the laptop lid. The result if the lid is closed, is it wakes, sleeps, wakes, sleeps, wakes, sleeps, until battery death.

Product Number: W2K28UA

Firmware versions tested: F.26, F.30

OS Revision: Linux 4.9


Trouble Shooting: A bug with Linux kernel maintainers has been opened.
https://bugzilla.kernel.org/show_bug.cgi?id=185521

 

Details: The bug has thoroughly evaluated by Intel kernel engineers and by Len Brown <lenb@k****l.org> who is the maintainer of many things in the Linux kernel: ACPI, INTEL IDLE DRIVER, INTEL PSTATE DRIVER, SIMPLE FIRMWARE INTERFACE (SFI), SUSPEND TO RAM, so his assessment that this is a firmware bug and not a kernel bug should be considered reliable.

The central problem is mentioned in these two comments:
https://bugzilla.kernel.org/show_bug.cgi?id=185521#c65
https://bugzilla.kernel.org/show_bug.cgi?id=185521#c91


-------------Update Jun 26, 2017

 

This is still a problem with:

    Version: F.33
    Release Date: 05/11/2017
    BIOS Revision: 15.51
    Firmware Revision: 48.59
