Hello mutial!

 

Welcome to the forums! Can you please provide a little more information to help with your issue?

 

Can you tell us what model (machine type) of T series you have and what operating system it is running? The machine type can be found on a sticker on the bottom of the unit.

 

Also,How long had it been working properly, and what changes were made, before this issue took place?

Thank you for being a part of the Lenovo Family,

Catie
