While holding that latch, slide the secondary latch and pull the battery upward.
Remove the battery completely and set it aside.

Critical: Never perform disassembly with the battery attached – it can short the motherboard.

IV. Internal Architecture Analysis

Once the motherboard is out, you can appreciate the design philosophy of the G0 series.

The Cooling System: The ProBook 450 G0 typically uses a unified heatsink and fan assembly for both the CPU and GPU (if dedicated graphics are present).

The Fan: A centrifugal blower fan pushes air through a copper fin stack located near the exhaust vent.
Maintenance: If your laptop was overheating, this is the moment of truth. Peel back the black mylar tape on the fan housing to reveal the impeller. Use compressed air to blast out the dust "carpets" that accumulate here.
Thermal Paste: If you removed the heatsink, clean the old crusty paste off the CPU die with isopropyl alcohol and apply a high-quality replacement (like Arctic MX-4 or Thermal Grizzly). This drastically reduces temperatures on Ivy Bridge/Haswell chips.

The CMOS Battery: This is a common failure point in older business laptops. On the G0, the CMOS battery is a coin cell (CR2032) wrapped in heat shrink with a two-pin connector. It is usually tucked near the RAM slots or the edge of the motherboard. If your laptop is losing time or throwing "RTC" errors on boot, replace this battery now.

The Processor: The G0 models typically feature socketed processors (PGA988 socket for Intel Core i3/i5/i7 3rd or 4th gen). This means the CPU can be upgraded. If you have an i3, you can technically upgrade to an i7, though you must check if your specific motherboard heatsink can handle the thermal load of the more powerful chip.
