Replacement power button board for IdeaCentre C540

This NShi power button board replaces the original LS-9301P part in Lenovo IdeaCentre C540 all-in-one desktops. It restores the front-panel power switch and LED indicator so the system can be turned on and its status seen at a glance. The component is supplied new and carries a six-month manufacturer warranty. It is intended for technicians or owners repairing a faulty power control assembly.

Sustained operation as a control interface

The board functions continuously while the computer is powered, passing the press signal to the mainboard and driving the status LED without active cooling. Because it handles only low-voltage switching current, thermal load remains negligible during extended uptime. No fan or heatsink is required, and the part does not degrade under normal desktop duty cycles. Reliability depends on the integrity of the solder joints and the flexible cable connection to the mainboard.

Blue PCB with integrated LED and flex cable

The printed circuit board is coloured blue and carries the power button actuator and indicator light in a single assembly. A flexible flat cable terminates in a connector that mates with the mainboard header inside the C540 chassis. Mounting points align with the original standoffs, so installation follows the factory layout. The part is specific to the IdeaCentre C540 line and will not fit other Lenovo models or standard ATX cases.

Questions about this item

Does the LS-9301P fan run loudly or get hot when the IdeaCentre C540 is on all day?

The board is a power-button and LED indicator unit; it does not contain a cooling fan that runs continuously.

What must already be installed in the IdeaCentre C540 for the LS-9301P board to function?

The board connects to the existing front-panel header on the system board of the IdeaCentre C540.

Will the LS-9301P board work if I keep the original power-switch cable from an earlier C540 chassis?

Yes, the LS-9301P matches the IdeaCentre C540 pin-out, so the original cable plugs straight in.
