What you’re seeing
- Setup stalls on 'Preparing your device for mobile management' or 'Securing your hardware' and then fails.
- An error screen shows 0x800705b4, which means the operation timed out.
- The Enrollment Status Page sits on Device preparation for 30 minutes or longer before giving up.
- Retrying sometimes works on the second or third attempt, or on a different network.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The laptop's TPM firmware is outdated, so TPM attestation during self-deploying or pre-provisioning mode fails.
- Network restrictions, proxies or firewalls block the Microsoft and manufacturer URLs needed for attestation.
- The device's clock is wrong, which causes certificate and attestation checks to fail.
- The Enrollment Status Page waits on too many apps or policies and hits its time limit.
- Virtual machines or devices without TPM 2.0 are being used with Autopilot modes that require it.
Why it matters
Autopilot is supposed to let a new laptop go straight from the box to the employee with everything installed. When it times out, the device is stuck, the employee cannot start work, and IT staff must reset and retry, sometimes many times. For businesses shipping laptops directly to remote staff, a failed setup can mean days of delay or a laptop shipped back. Repeated failures undermine the case for using Autopilot at all.
How AskTechGurus fixes it
Skip the trial and error. A certified engineer works on your actual system, finds the root cause, and fixes it properly.

A certified engineer diagnoses it
A vetted, US-based systems engineer claims your ticket, usually within minutes during business hours, and investigates over a secure remote session you can watch and end at any time.
Fixed and verified with you
The engineer resolves the root cause and confirms with you that it’s working. You don’t just get a workaround, and you get a plain-English summary of what was wrong.
Pay only when it’s resolved
Fixed price from $99, invoiced only after you approve the fix. If it isn’t resolved, you don’t pay.
Frequently asked questions
Is the laptop faulty?
Rarely. The timeout is more often caused by TPM firmware, network restrictions or how many apps the setup is waiting for.
Why does it work on some networks and not others?
Autopilot has to reach several Microsoft and hardware vendor services. Office firewalls, hotel Wi-Fi or filtering can block part of that process.
Can AskTechGurus help with Autopilot deployments?
Yes. A certified US engineer can review your Autopilot profile and the failing device through a remote secure session, starting at $99, and you pay only when setup completes.
