    Task Manager - Startup Tab - Last BIOS time

    In the Task Manager - Starup Tab - Last BIOS time it shows at 17615.2 seconds. That is almost 5 hours.

    I thought this was supposed to indicate boot up time? My boot time is very quick under 10 seconds, so what does this number mean?

    Hi, interesting thread here:
    windows 8 - Last BIOS time on Task Manager - Super User

    Note this thread contains opinion, some contradictory, some statements may not be accurate.

    Here are just a few of several interesting comments:
    "Although I'm not sure why you are getting it displayed as 0.0 seconds, the purpose of the "Last BIOS time" is to tell you how long it took to load the BIOS, it is the amount of time between pressing the power button, and seeing the screen that indicates that windows is loading."

    "If Secure Boot isn't enabled but your Windows is UEFI and has a GPT Windows partition this will always show 0.0 as the timer only works with Fast Boot...." (??)

    "The BIOS time is the time taken before the first beginning screen shown after pressing the power button."
    - this doesn't make sense- mine's 3.5s, but it takes about 12s to the lock screen from startup.

    Your time doesn't make sense.. there are comments about very long times you might care to search for.
