I bought the SB i7 with the performance base a few months ago and set it up with no issues. I recently decided to make more use of the Surface Pen last night. I clicked the top bottom and nothing happened. The pen would write, but would not bring up OneNote or Cortana (the default apps) which it did when I set it up originally. I went to the online trouble shooting steps Step 1: press top 5-7 and look for LED.. if Nothing Contact MS (which was the case). I chatted online with the MS Rep and went through Step 1 again. The solution is to mail back the Pen for complete replacement. Has anyone had this happen? Is it a problem with the Pens?
