I was experiencing some weird behavior from my laptop that hinted at a need for a driver or BIOS update and went to Dell Command Update to address. Unfortunately, I got the "Unable to retrieve system inventory information" error. So I uninstalled (completely and using Revo) the program and reinstalled the most current version. However, the problem persists. The online driver scan on the Dell support page also does not work anymore either. I have restarted the laptop several times. Nothing seems to work.
