Hello,

As Dell was telling upgrade to A19 BIOS, I do it to replace the original A17. From this operation my Precision M4600 never reboot but only shutdown.

I would like to downgrade to A17 BIOS but it seems impossible with an USB key, only a CD but for the moment I don't have any result.

As I read on Dell website, I do boot from a CD and put the A17 BIOS with a specific name. There is nothing on the SSD, I can do anything but for the moment I can't use my laptop.

Thanks for nay help, regards,

Fabrice

I have the A19 Bios on mine no problems. If you can I'd just try a fresh win10 install and see.
