Frequently asked questions

Which laptops use the LA-A341P motherboard?
File names in the catalog tie LA-A341P to the Lenovo ThinkPad Yoga S1 and Lenovo ThinkPad S1 Yoga. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-A341P do I have?
Files for this board mention Rev 1.0 and Rev 1A. 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.
What should I check before flashing the LA-A341P BIOS?
Read the original chip with a programmer and save two copies before writing anything. Some archives include EC/KBC firmware, which may need to be written to a separate chip. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
