Consider this: If you don't need a secondary HDD, simply replace your old 2.5-inch HDD with a 2.5-inch SATA SSD (e.g., Crucial BX500, Samsung 870 EVO). This requires no driver hunting, no BIOS confusion, and is guaranteed to work. hp probook 450 g2 m2 ssd compatibility

• Check the laptop's BIOS: Ensure the laptop's BIOS is up-to-date, as an outdated BIOS might not support newer SSDs.
• Check the chipset: The HP ProBook 450 G2 uses the Intel HM86 chipset, which supports SATA III and PCIe, but with limitations on PCIe speeds.

Part 5: BIOS and Firmware Prerequisites

Q: Can I install a PCIe NVMe M2 SSD in my HP ProBook 450 G2? A: While the laptop's M2 slot supports PCIe NVMe SSDs, the speeds will be limited to SATA III due to chipset limitations.

1. Power on the laptop and repeatedly press F10 to enter the BIOS.
2. Navigate to System Configuration > Device Configurations.
3. Ensure that "SATA Device" is enabled (the drive should be detected here).
4. Press F10 to save and exit.

WWAN Conflict: In some configurations, the M.2 storage device cannot be used if a WWAN (3G/4G) card is already installed in that slot.
