Sometimes customers may find that the system cannot enter one key recovery interface when pressing OKR button. It enters windows directly.

The symptom above may occur to the following systems:

U310/U410 with BIOS version lower than 13WW

There may be two reasons:

1. Customers delete service partition;

2. Customers disable IRST under windows;

Updating BIOS to 13WW could solve the problem.
