Loaded the system restore on the HDD, then upgraded it for free to W10. Spent the better part of the last two days trying to get rid of the Orange Exclamation Point for missing driver. Have tried everything on this forum, and Lenovos form. Basically everything has pointed me towards the Intel Mgmt Drivers. No luck. Anyone have any new ideas?

Thanks
Ron

Under driver properties, details, hardware IDs, what does it say?

Ven_xxxx&dev_xxxx should be enough info to pinpoint which driver it needs.

Device PCI\VEN_8086&DEV_1C3D&SUBSYS_21CE17AA&REV_04\3&b1bfb68&0&B3 requires further installation.

That is the Intel Management Engine interface. Give this a try:

For what its worth, I had to delete the later dated one, then reinstall this one, to make it work. Geez!

Thanks
