Frequently asked questions

Which laptops use the DA0WJ5MB6F0 motherboard?
File names in the catalog tie DA0WJ5MB6F0 to the HP PRO 3420 and HP 120-1050XT. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of DA0WJ5MB6F0 do I have?
Files for this board mention Rev D, Rev E and Rev F. 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 DA0WJ5MB6F0 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.
