Frequently asked questions

Which laptops use the LA-D707P motherboard?
File names in the catalog tie LA-D707P to the HP 15-AY, HP 15 AY125NR, HP 250 G5 and HP 15 AY127CA. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-D707P do I have?
Files for this board mention Rev 1.0. 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-D707P BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 8 MB images; the dump size must match your chip. 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.
