T480 boot delay


I have a problem with my brand new T480.

It is a campus model upgraded to 16GB RAM and 512GB SSD.

Today, I installed Windows 10 without problems and updated the bios (1.12).

After severals reboots I recognized, after the Lenovo boot logo,

is a delay with approximately 30 seconds until the Windows 10 boot icon appears.

During the delay there is only in the left corner a blinking underscore.


I changed boot order and activated diagnostic boot.

I see directly after the boot informations for <1sec the message "Thinkvantage active protection sensor diagnostics start." (I don't know if this is normal.) Then again the delay of 30seconds, until Windows 10 boots.


I downgraded bios back to 1.11. Still same problem.

I installed debian but still the delay.

Also I set the bios to default values.


Is the hardware damaged?

Re: T480 boot delay

Germany is a long distance from San Francisco, and I cannot be sure without seeing the machine, but I can say that a bad SSD can act like you describe.

Re: T480 boot delay

You might try togggling the following BIOS settings on/off to see if the affect your boot times.    Those settings may be requried in your environment, but it at least you would know the cause.


  • Intel Active Management   (Config >> Intel AMT)
  • Security Chip (TPM)  (Security >> Security Chip)


Best of luck,

Re: T480 boot delay

I'm also experiencing a slow boot time on my T480. From power button to login screen it can sometimes take 35-40 seconds which is very slow for a pci-e m.2 ssd. My 5 year old ThinkPad S1 Yoga boots in less than half the time of this!


In my case the red Lenovo splash screen with the loading dots will take a good amount of time before completing and reaching the login. Hoping Lenovo fixes this soon.
