Question about HP EliteBook 640 14 inch G11 Notebook PC, Intel Core Ultra 5, 35,6 cm (14"), 1920 x 1200 Pixel

A second hard disc (second SSD) cannot be installed in this notebook as it only has one M.2 slot for an SSD. The HP EliteBook 640 G11 has a single M.2 slot for a 2280 NVMe SSD, there is no second slot for an additional SSD.

This means that expansion with a second internal SSD is not possible. A second storage slot is only available on certain other models or configurations with a non-WWAN base unit and corresponding slot, which is not the case here.
