 Hello, this is Nick from Laptop Media, and today we will show you how to open the HP Elite Book 840G10. To access the internals, you have to undo just 5 captive Philips head screws. Then pop the bottom panel in the zone behind the hinge cover to create a gap between the base and the plate. After that work your way around the sides and the front.

There is a small thermal pad on the inside of the metal bottom plate for cooling the SSD. Our laptop has the optional 51.3 watt hour battery. The default version is a 38 watt hour model. To remove the battery, detach the connector from the main board and undo the four Philips head screws that keep the unit in place. The optional capacity lasts for 10 hours of web browsing, or 7 hours and 42 minutes of video playback. Not bad given the high res 120Hz display. To achieve that, you have to select the HP optimized modern standby power plan that can be found in the control panel's power options submenu. Also, you have to apply the balanced preset in the windows power and battery section. The RAM section is protected by a metal plate. For memory upgrades, there are two sodoms. According to HP, the two slots fit up to 64GB of DDR5, 4800MHz or 5200MHz RAM in dual channel mode. However, since the CPU can support up to 96GB, this laptop likely wouldn't have issues running a larger amount of memory than the official manufacturer's specified limit. Here, the memory sticks are rated at 5600MHz, but they operate at 4800MHz. Below the cooling fan, you can see the W1 slot for optional LTE or 5G connectivity. Storage wise, you get only one M.2 slot for 2280 Gen4 SSDs. There is a cooling pad below the NVMe. The cooling system looks good for an IGPU only laptop. It has one large fan, a pair of heat pipes, one top mounted heat sink, and a heat spreader.
