Genuine OEM Backlit Keyboard for Latitude E7440

This is a new Dell 4CTXW replacement keyboard built specifically for the Latitude E7440 and E7450 series. It restores full typing function with a US QWERTY layout and integrated white LED backlighting. The matte black finish matches the original chassis aesthetic. Buyers needing a non-backlit version or a different regional layout cannot use this part.

Low-Profile Design with White LED Illumination

The slim profile measures approximately 11.25 x 4.25 x 0.25 inches and weighs very little, adding no bulk to the ultrabook chassis. White LED backlighting provides clear key visibility in dim environments without increasing power draw noticeably. Keys use a soft-touch finish for comfortable long-form typing. No thermal or acoustic changes occur because the keyboard is a passive component.

Direct Replacement for Worn

This part replaces a failed, liquid-damaged or backlight-dead factory keyboard on supported Latitude models. Installation uses the existing ribbon cable and screw points, requiring no adapter or firmware update. The upgrade is worth it when the current unit has broken switches, uneven backlighting or missing keycaps. It does not add backlighting to a non-backlit system or change the physical layout.

Domande su questo articolo

How do I install the 4CTXW keyboard on a Latitude E7440, and which step do people get wrong?

Remove the battery, unscrew the bottom case, detach the old ribbon cable by lifting its ZIF latch, then seat the new cable fully before locking the latch — the common error is leaving the latch open or inserting the cable crooked.

What maintenance or replacement will the 4CTXW backlit keyboard need later?

The white LED backlight cannot be serviced separately; if brightness fades or keys fail, the entire 4CTXW unit must be replaced as a single spare part.

What limit appears first during sustained typing on the 4CTXW keyboard?

The slim 0.6 cm profile and integrated membrane mean heat from the chassis can make the deck feel warm during long sessions, which is the first comfort limit users notice.
