FAQ

Frequently asked questions

What you most want to know about on-site service in Changning

Will reinstall lose my files?

We fully back up and migrate first and only start once your files are confirmed safe. Old-device data is securely cleaned before disposal.

Can you install the software I used before?

Yes. Office software, industry software and printer drivers are set up the way you used them, tested before we leave.

Is the system genuine?

We install a genuine OS. Licensing is handled to your machine's situation, and we explain the current state when done.

Do I really need to reinstall?

Not necessarily. We diagnose first and repair where possible — many blue-screen, slowdown and boot issues are fixable, and we only suggest reinstall when repair won't do.

How much does WiFi coverage cost?

AP deployment is RMB 150–400/AP, whole-home plans from RMB 800, depending on area, floors and whether cabling is needed. Survey is free — we give a point map and budget first.

How soon can you arrive?

As fast as 30 minutes if close and traffic is light, most jobs scheduled the same day. Survey and plans are free.
