Inside HP ProBook 455 G9 – disassembly and upgrade options
HP never disappoints when it comes to upgrade options on their business notebooks. Perhaps, this is one of their biggest strengths.
1. Remove the bottom plate
It is pretty easy to take this notebook apart. Just undo the 5 Phillips-head screws, and pry the bottom panel with a plastic tool.
Our device came with a 51.3Wh battery pack. It lasts for 12 hours and 30 minutes of either Web browsing, or video playback. To take it out, you have to unplug the battery connector from the motherboard and undo 6 Phillips-head screws.
3. Memory and storage
Memory-wise, you get two SODIMM slots for up to 32GB of DDR4 RAM in dual-channel mode. As for the storage, there is one M.2 PCIe x4 slot.
4. Cooling system
In terms of cooling, there are two heat pipes, which connect to a medium-sized heat sink. Then, a single fan blows the heat away from the device.
