How to open HP EliteBook 840 G10 – disassembly and upgrade options

Ensure the HP EliteBook 840 G10 is powered off and placed on a soft surface to prevent scratches.
Remove the 5 captive Phillips-head screws that secure the bottom panel.
Use a plastic pry tool to gently pop open the bottom panel starting from the zone behind the hinge cover, then proceed to detach the panel by working your way around the sides and the front.

Step 2: Battery Removal

First, disconnect the battery by unplugging its connector from the motherboard.
Remove the four Phillips-head screws holding the 51.3Wh battery (or the standard 38Wh version) in place and lift the battery out of the laptop.

More info: The optional 51.3Wh battery provides up to 10 hours of web browsing or 7 hours and 42 minutes of video playback.

Memory Upgrade

Locate the memory section beneath the metal plate and remove it to access the two SODIMM slots available for upgrades.
While officially supporting up to 64GB of DDR5-4800MHz or 5200MHz RAM, the CPU’s compatibility with up to 96GB suggests the laptop can handle more memory than specified by HP.
