How to replace the battery in a Dell Latitude 5410?

This guide walks you through a safe, step-by-step battery swap on the Latitude 5410. We’ll cover tools, safety prep, the exact disassembly sequence, and reassembly + calibration. Important fit note: the 68Wh (4-cell) battery extends into the 2.5″ HDD bay. If your laptop still has a mechanical hard drive installed, choose a 42Wh or 51Wh battery—or migrate to an M.2 SSD and remove the 2.5″ drive before installing 68Wh.

Before you start (safety & tools)

Power down Windows completely. Unplug the AC adapter and all peripherals.
ESD safety: Work on a clean, static-safe surface. Ground yourself or use an anti-static strap.
Flea-power drain (optional): After shutdown, hold the power button for ~10–15 seconds.
Tools: Phillips screwdriver (for captive screws), plastic scribe/opening pick, small parts tray.

Fit reminder: 42/51Wh (3-cell) fit alongside a 2.5″ HDD. The 68Wh (4-cell) occupies the 2.5″ bay; use only with M.2-only systems (no 2.5″ drive/caddy installed).

Step 1 — Remove the microSD card

Prerequisites: Follow the procedure in “Before working inside your computer”.

Push the microSD card to release it from the computer.
Slide the microSD card out of the slot and set it aside.

Step 2 — Remove the base cover

Prerequisites: Safety steps above, and microSD card removed.

Loosen the eight captive screws that secure the base cover to the computer.

Using a plastic scribe, pry the base cover from the top-left corner and continue along the sides to release the clips.

Prying open the Dell Latitude 5410 base cover with a plastic scribe — Work slowly with a *plastic* tool to avoid marring the chassis.

Lift and remove the base cover away from the computer.

Step 3 — Remove the battery

Prerequisites: Safety steps, microSD removed, and base cover removed.

Disconnect the battery cable from the connector on the system board.

Disconnecting the Dell Latitude 5410 battery cable from the motherboard — Gently lift the connector straight out—do not pull on wires.

Loosen the single captive screw that secures the battery to the palm-rest assembly.
Lift and slide the battery away from the palm-rest assembly.
Remove the battery from the computer.

Install the new battery

Position the new battery in the bay. Make sure the cable orientation matches the board connector.
Slide it into place, seat it flat, and tighten the captive screw to spec (snug, not overtightened).
Reconnect the battery cable firmly and evenly.

If upgrading to 68Wh: Verify your system is M.2-only (no 2.5″ HDD or caddy installed). The 68Wh (4-cell) occupies the 2.5″ bay; it will interfere with a mechanical HDD. For HDD systems, use 42/51Wh—or migrate to M.2 first.

Reassemble and validate

Reinstall the base cover: align clips, press around the edges, then tighten the eight captive screws in a cross pattern.
Reinsert the microSD card (if used).
First boot & checks: Power on and tap F2 to enter BIOS. Confirm Battery is detected and AC Adapter Type shows the correct wattage.
Calibrate once: In Windows, charge to 100% uninterrupted, then discharge to ~10–20%, and charge back to 100% to re-teach the fuel gauge.

Care tips for longer battery life

Keep vents clear; avoid heat build-up. High temperature accelerates wear.
When docked all day, consider a charge cap (e.g., 60–80%) in Dell Power Manager to slow aging.
If the system shows “plugged in, not charging” at ~80%, a charge limit may be active by design—disable it before travel.

Recycling

Do not bin old lithium-ion packs. Recycle the removed battery through a certified e-waste program.
