Frequently asked questions

Which laptops use the BA41-02234A motherboard?
File names in the catalog tie BA41-02234A to the Samsung NP730U3E. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of BA41-02234A do I have?
Files for this board mention Rev 1.0 and Rev 1.1. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.
