Frequently asked questions

Which laptops use the LA-4107P motherboard?
File names in the catalog tie LA-4107P to the HP Pavilion DV4, HP DV4-2080 and HP CQ41. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of LA-4107P do I have?
Files for this board mention Rev 1.0 and Rev 2.0. 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-4107P BIOS?
Read the original chip with a programmer and save two copies before writing anything. File names for this board mention 4 MB images; the dump size must match your chip.
