We tried reaching you on a private message asking for the Service Tag number to ascertain the warranty but did not receive a response. Please feel free to reply to the private message whenever you are available.

Thank you for your response.

Have you tried it with Secure Boot turned off? Sounds like the second drive is causing the BIOS to hang up during POST. Try tapping F12 when you see the Dell splash screen. Then select the M.2 drive from the list which will force booting from the M.2 drive. If it boots faster then you can figure that the boot order or boot configuration is possibly suspect during boot.

Thank you so much for ur reply ..

• The problem is that after I push the power button, there is no response through the first 30 seconds, after that the Dell splash screen is shown .. this 30 seconds are the problem.

I tried the the disabled secured boot and there's no change
