1. I have tried that before posting after finding online that the PM could cause this issue.
2. Sometimes it will copy small amounts, but it will eventually drop out. I've had it drop when only surfing the net.
3. This is a brand new (to us) laptop model (t450s). We haven't used any driver other than the latest from Lenovo (12.12.80.1950). I tried the latest Intel driver package from 6/2/15 which installed v. 12.12.80.19, we are still experiencing the issue. I don't want to go back in revisions b/c we'll run into the problem with SEP and the card not working coming out of sleep mode that the latest revision fixed.
4. I have not; I plan on making calls today. I've been busy but have the time to look into it this week.
