I have recently bought a Dell refurbished Latitude E6430s laptop.It is a gleeming like new laptop with Windows 10 newly installed and no issues showing in device manager and only the usual runtime broker  DCOM error in event viewer. It works like a dream. This is a big improvement on the 3 year old **bleep** laptop I have. The last creators fall update finally wrecked it so it would not even boot properly. I just gave up and installed Linux Mint on it. Add to that **bleep** have not provided any driver or BIOS updates for Windows 10 since I upgrade it from W8.1. They will only support the factory installed OS.

I like Dell because they are still providing driver updates for W10 on a machine that had W7 factory installed.

My only problem is it has BIOS version A01 and the latest is A19. Can I update the BIOS to A19? I have read that I may have to update to an older version first.

 "On some occasions you may need to install an intermediate BIOS version before updating to the latest version. This is called BIOS dependency;"

I cant find any info on this in "important information". Any ideas please?
