U310410 OKR button cannot enter one key recovery issue


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


Affected configurations

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.
