@Lingli If you've gone through all the steps mentioned in this link and yet the issue persists, this could be a hardware malfunction and I suggest you talk to HP support and discuss your options:

follow the below steps to get started:

1) Click on this link - www.hp.com/contacthp/

2) Click on "Continue as guest".

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

After clicking the link - www.hp.com/contacthp/

there is no choice for clicking on "Continue as guest".

Anyway, my PC's serial number is [edit]. Thanks.
