HP Laptops EliteBook Series 820 G3

= General Information =

The laptop is very servicable and does not seem to have a PCI ID black-list.

It is possible to install a 2,5" disk and a M.2 SSD at the same time, as long as the M.2 is a PCIe device (the SATA port is shared).

The battery can be replaced with the slightly larger one from the 4th gen 820 but it is recommended to get a replacement from a 3rd party as GreenCell because HP seems to mostly sell old stock with long shelf storage times. Replacement batteries cost ~50 USD excl. VAT or ~50€ incl. VAT. The device does work with generic 3rd party batteries.

= Parts =

At least in Europe, HP sells replacement/spares to the public, they are pricy though because you will not get a general discount as a non business buyer. Link to the (maybe not exact) Parts-Picker page
