HP EliteBook 840 G10 review – Business Laptop with a Breathtaking Display

Disassembly, Upgrade options, and Maintenance

To access the internals, you have to undo just 5 captive Phillips-head screws. Then, pop the bottom panel in the zone behind the hinge cover to create а 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 51.3Wh battery. The default version is a 38Wh model. To remove the battery, detach the connector from the mainboard, and undo the four Phillips-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.

The memory section is protected by a metal plate. For memory upgrades, there are two SODIMMs.

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. Below the cooling fan, you can see the WWAN slot for optional LTE or 5G connectivity. Storage-wise, you get only one M.2 slot for 2280 Gen 4 SSDs. There is a cooling pad below the NVMe.

Here, the memory sticks are rated at 5600MHz but they operate at 4800MHz.

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.

ich habe das Teil von meiner Firma bekommen, ohne eine Wahl zu haben. Ich finde es katastrophal. Der Akku ist sehr schnell leer und lässt sich nur mit dem Original Ladegerät aufladen. Der Lüfter läuft fast die ganze Zeit und ist sehr laut, dabei nutze ich nur Office Anwendungen ohne aufwändige Videos oder ähnliches. Kann nur abraten von dem Gerät.
