How to open HP EliteBook 640 G10 – disassembly and upgrade options

Ensure the HP EliteBook 640 G10 is powered off and placed on a soft, clean surface to prevent scratches or damage.
Undo the 5 captive Phillips-head screws on the bottom of the laptop. These screws will stay attached to the bottom panel, minimizing the risk of loss.
Lift the bottom panel near one of the top corners to create a slight gap, then use a thin plastic tool to pry the corner. Continue prying along all sides of the device to fully remove the panel.

Hint: Be gentle when prying to avoid damaging the internal clips or the laptop casing.

Step 2: Removing the Battery

Disconnect the battery by unplugging its connector from the motherboard.
Remove the four Phillips-head screws securing the battery to the chassis, then lift the 51.3Wh battery from the device.

Caution: Handle the battery and its connector with care to avoid any damage.

More info: The 51.3Wh battery provides up to 12 hours and 30 minutes of web browsing or 9 hours and 5 minutes of video playback, offering solid battery life for extended use.

Memory Upgrade

Locate the two SODIMM slots available for memory upgrades.
Install up to 64GB of DDR4-3200MHz RAM in dual-channel mode for enhanced performance.

Hint: Ensuring both RAM slots are filled can optimize the laptop’s performance through dual-channel mode.
