Questions about this item

Does the power switch board draw any power or generate heat while the A540 runs all day?

The board only completes the power-on circuit when pressed; it consumes no measurable power and produces no heat during normal operation.

What must I already have to install this replacement on my ideacentre A540?

You need a compatible Lenovo ideacentre A540-27ICB F0EK, A540-24ICB F0EL or A540-24API F0EMAIO unit, plus basic tools to open the chassis and disconnect the old board.

Will this switch board work if I keep the original motherboard and display in my A540-24ICB?

Yes, it matches part numbers 01LM916, NS-C236, NS-C942 and 5C50Z66263 for those exact models, so the existing motherboard and display remain fully compatible.
