If a computer goes into Standby or Hibernate mode while the Chromeleon 7 instrument controller is running, the USB subsystem will become unavailable. As a result, USB-dependent devices (instruments and the license key) will stop functioning and operation is interrupted.

Procedure

  1. From the Control Panel, open the Power Options.
  2. For your selected plan, click Change plan settings.
  3. Set every drop-down list to Never.
  4. Click Save Changes.
