Lenovo USB 3.0 Dock performance terrible

JamesH · 10-20-2013, 01:10 PM

Hi folks,

I'll try and reproduce this internally.

Some questions:
@wonderose - what is the system set to do when you close the laptop lid?
What software does v7.2.8000.17 refer to?
Is your mouse wired or wireless?
What kind activity produces the most CPU usage?

@wolfindersteppe
Is your mouse wired or wireless?
What kind activity produces the most CPU usage?

In the meantime can you upgrade to R7.4M2 and post the logs from the support tool to help me investigate this? The tool can be found here:

Thanks,
James

I hope this answers your questions.
But I have to say that, as I now use a simple HDMI cable, I really did uninstall the DisplayLink software.

1)
As far as Windows energy options are concerned, the system is set to do nothing. But closing the lid does turn on the external monitor, while at the same time turning off the screen of my Helix (as well as its touch function).

2)
DisplayLink Graphics 7.4.51587.0 (not the version I mistakenly mentioned in my previous post)
DisplayLink Core Software 7.4.51572.0

3)
My mouse is wired. Bluetooth is disabled.

4)
Continuous cursor movement slowly increases CPU usage (up to 15% and more), not to mention flash videos in Firefox (up to 25%), all this with the corresponding surges in fan movement.
