Replacement keyboard for Inspiron 9100 and XPS Gen1

This genuine Dell A157 keyboard restores typing function to the Inspiron 9100 and XPS Gen1 laptops. It matches the original US English QWERTY layout with 87 keys in black. The wired connection installs directly without adapters. Part number Y3740 confirms exact fit for the listed models.

For owners of the listed Dell models only

Buyers repairing an Inspiron 9100 or XPS Gen1 will find the correct layout and connector here. Anyone with a different Dell series or another brand should look elsewhere because the key arrangement and ribbon cable will not match. The US English legends also make it unsuitable for non-US layouts.

87-key US QWERTY layout

The keyboard provides exactly 87 keys in a US English QWERTY arrangement. This specific layout and key count determine compatibility with the target laptops. If your machine requires a different key count, language or regional layout, this part will not fit.

Questions about this item

Does the Dell A157 keyboard draw enough power to warm up the laptop after hours of typing?

It connects by a thin ribbon cable that carries only signal current, so it adds no measurable heat and has no fan or power draw of its own.

What connector must the Dell Inspiron 9100 or XPS Gen1 motherboard provide for this A157 keyboard to work?

The board needs the matching ZIF ribbon socket that accepts the keyboard’s flat-flex cable; no USB, PS/2 or wireless link is used.

Will the Dell A157 keyboard fit a newer Dell chassis that still uses an 87-key US QWERTY layout?

The A157 is moulded for the Inspiron 9100 and XPS Gen1; different mounting points and ribbon routing mean it will not seat correctly in later models.
