 Hello, this is Laptop Media, and today, we will show you how to open the HP Elite Book 840G9 and what's inside of it. Accessing this notebook's internals is pretty easy. You just need to undo the 5 captive Philips head screws. Then, pry the bottom panel using a plastic tool, starting 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. Inside, we find a 51Wh battery pack. It lasts for 14 hours and 30 minutes of web browsing, or nearly 12 hours of video playback. To take it out, unplug the battery connector from the motherboard, and undo the 4 Philips head screws that secure it to the chassis. You can upgrade the memory via 2 Sodom slots, hidden beneath a metal bracket. The maximum supported amount is 64GB of DDR5 RAM, working in dual channel mode. Storage wise, there is 1 M.2 PCIe X4 slot, which supports Gen 4 SSDs. The cooling comprises one heat pipe, a heat sink, and a medium sized fan.
