Dell Latitude 14 5440 review – surprisingly good
Disassembly, Upgrade options, and Maintenance
To gain access to the internals, you have to undo 8 captive Phillips-head screws. After that, raise the bottom plate close to one of the hinges to open a gap. You can begin prying the panel with a thin plastic tool starting from the sides and then the front. The back should be last.

Here’s how the bottom plate looks on the inside.
Our device has the optional 54Wh battery, the base version is a 42Wh variant. Before removing it, unplug the connector from the mainboard, and undo the 5 Phillips-head screws that keep the unit in place. The optional capacity is enough for 14 hours and 17 minutes of Web browsing, or 8 hours and 20 minutes of video playback.
You get two SODIMMs for future upgrades. This notebook has two iterations – with DDR4 or DDR5 memory. Depending on the RAM version, the maximum possible amount could be 64GB of DDR4-3200MHz, DDR5-4800MHz, or DDR5-5200MHz memory in dual-channel mode. The laptop in front of us has DDR4 slots.
On the right side of the battery, you can see the single M.2 slot compatible with 2230 Gen 4 SSDs. The NVMe is covered by a metal shroud that has a small thermal pad on the inside. The WWAN slot for optional 4G or 5G connectivity is placed next to the cooling.
The thermal system comprises one decently sized fan, a heat sink, one heat pipe, and a heat spreader.

Dell’s battery life is so horrible. I will be very happy if it lasted 2 hours. We have several Latitudes and Precision laptops.
Très mauvais produit.
Au bout de 6 mois touche E du clavier illisible car peinture partie. Pas pris en charge par la garantie!
