Our office got 6x new Dell computers.  When the UB500 adapter is installed the Dell computer will not power on or boot normally.  We get a slow blinking white light on the power button.

1) Unplugging the UB500 will result in the Dell computer powering up and booting right away!

2) If the UB500 is left plugged in...the computer might power up and boot after several hours or the next day

We have contacted dell support and they checked the Dell BIOS but so far have not been able to resolve the issue.

Items they checked included:

1) Latestes Dell BIOS 1.8.2

2) BIOS boot order

3) WAN & LAN enabled on boot

The Dell computers are brand new - DELL DESKTOPS DELL PRO MICRO QCM1250 35W TPM 16GB 256GBSSD INTEG NSTND WIN11PRO VPN:1D5HX

Has anyone encountered this problem?
