 Hello, this is Laptop Media, and today, we will show you how to open the HP Elitebook 640G9 and what's inside of it. You need to undo only 5 captive Torx head screws to access this notebook's internals. Then, pry the bottom panel with a plastic tool. It's best to start from the back. Please remember, it would be of great help to us if you just hit the like button and subscribe to our channel. That would motivate us to make even more and better videos for you. Our configuration features a 51.3Wh battery pack. It got us through 13 hours of web browsing or 10 hours of video playback. To remove it, unplug the battery connector and undo 4 Philips head screws that keep it in place. Memory-wise, you get 2 Sodom slots for up to 64GB of DDR4 RAM in dual-channel mode. Respectively, the storage options comprise 1 M.2 PCIe X4 slot with the support of Gen4 SSDs. As for the cooling, you get one heat pipe, which leads to a heat sink. There a single fan blows the heat away from the chassis.
