For additional storage or expansion cards, power down the system and install components into the available drive bays or PCIe slots following HP hardware guidelines.

Recommendations

For best day‑to‑day performance, keep Windows and drivers up to date, expand memory to 16 GB or more for heavier multitasking, and use the NVMe SSD for primary applications and the OS. Use wired Ethernet for stable network connections when required, and refer to HP management utilities for system diagnostics and BIOS configuration.
