For Online Computer Support, Ask a Computer Technician
I'm sorry about the issue. Can you please check at the back/bottom of the Lenovo Utra book for the model of it?
Does your Lenovo Ultrabook laptop have windows 7 or 8 or 10, etc.?
Are you currently able to log in and use the laptop?
Is there any data files you need to keep on the laptop? Or do you have backup?
Please reply at the box below. Thank you.
