Quick-start card (A6, two sides)
Print at 100 % on card stock; fold nothing. Side 1 faces up in the box.
Side 1 — plug in
x240-kbd — a ThinkPad X240 keyboard, ClickPad and TrackPoint as one USB device.
- Plug the USB cable into any computer, phone or tablet with a USB host. No drivers: it enumerates as a keyboard + mouse.
- Type. The ClickPad moves the cursor; its bottom corners are left/right click.
- Push the red stick for the TrackPoint. Rest your finger on it lightly — it measures force, not travel.
- Power button: hold ½ s for the system’s power/sleep dialog. A tap does nothing.
FN layer (hold FN):
| F1 mute | F2 vol − | F3 vol + | F4 mic mute |
| F5 bright − | F6 bright + | F7 display | F8 wireless |
| F9 settings | F10 bluetooth | F11 backlight | F12 print screen |
| PgUp home | PgDn end | ← prev track | → next track |
| Esc = FN lock |
Side 2 — keep it working
Firmware updates. Hold Esc while plugging in (or press the reset hole on the
underside with BOOTSEL held). A drive named RPI-RP2 appears; drag the new .uf2 onto
it. The keyboard restarts by itself. Firmware and instructions:
github.com/nikolareljin/x240-kbd
Cursor too fast or slow? That is a firmware constant
(SYN_TOUCHPAD_DIVISOR, SYN_TRACKPOINT_MULT); rebuild and update as above.
Opening it. Deck screws out from below, lift the deck straight up, unlatch the two ribbon-cable tabs. Nothing is glued.
Don’t. Bend the ribbon cables tighter than a 5 mm radius. Pull the cable by the plug. Run it from a USB hub that cannot supply 500 mA if the backlight is on.
