HP ProBook 450 G9 Core i5 12th Gen, 8GB RAM, 256GB SSD (Refurbished) – Ten Cores for the Hybrid Workday
The HP ProBook 450 G9 is a 15.6-inch business laptop that moves HP’s ProBook line onto Intel’s 12th Gen hybrid architecture. Its Core i5-1235U processor combines 2 Performance-cores and 8 Efficient-cores (10 cores, 12 threads), boosting up to 4.4 GHz. As a result, it keeps a Teams call smooth while background tasks such as file syncing, antivirus scans and updates run on the efficient cores. In addition, 8GB of DDR4-3200 RAM covers everyday office multitasking, and two SODIMM slots leave room to upgrade later. Meanwhile, a 256GB PCIe NVMe SSD starts Windows quickly and opens documents without the lag of older hard drives.
The 15.6-inch Full HD (1920 x 1080) anti-glare IPS display stays comfortable during long spreadsheet sessions, and the spill-resistant keyboard with a numeric keypad speeds up figures and data entry. Furthermore, the 720p HD privacy camera has a physical shutter, which keeps home-office video calls private when you are off camera. For connectivity, you get three USB-A ports, USB-C with DisplayPort, HDMI, RJ-45 Ethernet and Wi-Fi 6. Consequently, the G9 moves easily between a desk in Westlands, a home office in Syokimau and a client boardroom.
