    Help! Brand new laptop slow cold boot at 70 Seconds to login screen


    Hello,

    I am really need some expert assistance here.
    I just bought a brand new gaming laptop everything is fine except for cold boot and shutdown are very slow.
    I tried google to get some insight on how to fix it but none of the basic method fix my issue.

    Tried turn on/off fast start from BIOS and system config.
    Disable all start-up programs
    Disable all non-Microsoft services

    I installed the Windows Performance Analyzer and ran a boot test CPU usage. The result shows Session Init, Winlogon Init, Explorer Init and Post Boot are 17 seconds each boot phase. I have no idea what to disable to improve the boot speed. I attached the result as a reference.

    I would like to thank you for your help in advance.

    Hi @kkravan and welcome to Tenforums,

    the 17s is a bit higher for a computer with these specs.
    Usually what causes a delay in the phase is drivers. So make sure all your drivers are up to date, including Bios.

    If you can't fix that, share your boot trace I could tell you which driver is involved.

    I hope this will help :)

    The boot trace was taken with the xbootmgr.exe tool, and it misses the call stacks !
    There is a lot of CPU usage during the session init phase but I can't dig in the call stack to see what happens !

    This boot trace shows that the session init phase is not too long 8s. But the logon phase is 68s.
    Most of the delay is spent waiting for entering the credentials.

    I suggest you download and use autologon from sysinternals, to bypass the logon phase and get accurate measure. Then take another boot trace.

    Thank you. So I enable autologon according to your link and re-run the boot trace.
    Now the delay seems to be back to before at 70 seconds.

    I suspect a driver signature issue as part of the problem;

    Disable temporarily the driver signature verification at boot using this command:
    bcdedit /set testsigning on

    restart your computer and check the boot time.
