About the EliteBook 820 / 840 / 850 G3

The HP EliteBook 820 / 840 / 850 G3 was sold in 2016, with a 12.5"–15.6" display, and uses Intel Core 6th gen processors. It belongs to the EliteBook 800 Series range, and we keep or source parts for every common repair.

Its processor is not on Microsoft’s Windows 11 supported list, and Windows 10 support ended in October 2025. We can advise on keeping it secure, alternatives such as ChromeOS Flex or Linux, or whether replacement makes more sense.
