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

kkravan · 03 Mar 2021

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.

Hardware: i7-9750H, 16GB ram, 500GB m.2 nvme, RTX 2070 Max-Q
Windows 10 Home, Version 20H2

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 :)

It asks me to sign in ! Can you make the share public ?

Very sorry about that. I just change it to public access. Thank you!

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 !

you need to record a new boot trace with WPR tool:

Here is a tutorial if you need help:

Hello Zinou,

Sorry for the inconvenience.
I just did another one with your instructions.

I hope I am doing it correctly this time.

Thank you!

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.

kkravan · 04 Mar 2021

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.
