    Great info. Thanks for trying it out. Yours seems to be particularly quiet.

    Anybody with HDD/SSD Password option in BIOS?

    Apart from the fact that you're not supposed to double-post, your question really has nothing to do with either thread you posted in.

    If you're really looking help, try creating your own post.

    I have a new 9550 and very pleased with it.

    The only issue I am having (so far...) is the opposite to what several people have reported here.
    Rather than not waking up from sleep, it won't go to sleep unless I force it via the power option on the start menu.

    It has the default settings. But closing the lid or leaving it unattended has no impact - come back hours later and it has not gone to sleep.
    The screen goes off, but the machine is not going to sleep. (when I return it is not asking me to log in again)

    The annoying this is that if I am running on battery, it simply drains my battery away.

    I can only presume something running in the background fools the machine into thinking it is still in use.

    Ideas?

    Another question.
    My previous Dell had an option to prevent the battery from being over-charged whjen it was just primarly on mains power.
    But I dont see that on the 9550 power options.
    It is no longer a problem?

    They are now part of BIOS(UEFI) settings.

    I have the same issue - I will seemingly reliably get a crash with CRITICAL PROCESS DIED when I close the lid and reopen it 20 seconds later (Win 10 Pro, 4k display, 512GB PM951 drive)

    I have the latest BIOS in AHCI mode and have removed Intel Rapid Storage but loaded its AHCI drivers and the Samsung NVMe controller

    this is a known . semi known issue. there are various sleep/hibernate/shutdown issues where it either wont sleep, or goes to sleep only to restart a few seconds later and boot up again
