I invite you to read Targus blog on the specific ITEM#51 issue description.
http://ktqinc.com/2015/01/16/targus-...em-51-defects/
Then, when you are ready, I invite you to read our FAQ on elements we will need to investigate your problem.
The more information you give from the onset, the fewer emails we will have to exchange, the fewer tries we will have to do.
When we don't have logs, we can only do some general informed guesses based on the information provided at the time... Yes, a guess can be wrong.
