⚙️ Fit Notes

• This is a Half Mini PCIe WLAN card (not M.2 / NGFF).
• Some systems (especially certain HP/Lenovo models) may enforce an approved wireless-card list. The safest approach is to match your original spare/FRU/part number exactly when possible.
• If your system uses a separate Bluetooth module, replacing the WLAN card will not add Bluetooth.
