Running Win8.1 on a i7 ultrabook. Connected to the 3900 I have a dual-bay HD dock (with 2 HDs) (USB3), 2 1080P monitors (HDMI, DVI-D), wireless KB+mouse, a USB2 DVD drive, a USB3 thumb drive, and an iPhone 4s.
Two problems I have noticed:
- Occasionally the wireless KB+mouse will go dead. Unplugging and re-plugging the wireless dongle works every time for recovery.
2.a Occasionally the laptop will start beeping, every 7 or secnods, continuously. It’s not a familiar Windows beep, it’s a multi-note sequence. When the beep sounds, mouse is completely unresponsive for about 7 seconds, and then recovers for a second. The unresponsive mouse occurs ONLY when the mouse cursor is on one of the 3900-connected displays. When the mouse cursor is on the laptop’s internal display, there is no responsiveness problem.
2.b When this beeping occurs, I assume it is an error alert from the Plugable 3900 docking station. Disconnecting the 3900 and reconnecting the 3900 seems to remedy the beeping as well as the unresponsiveness.
2.c While this problem (beeps, unresponsiveness) seems to be associated with the 3900, and I assume this to be an error alert mechanism, I am unaware of any error message or alert box which would clarify the nature of the error or the possible cause of the error. This is all assumption, of course, perhaps you can shed some light on this.
