How to find your motherboard number
One laptop model is often sold with several different motherboards (Intel or AMD, with or without a graphics chip). A schematic or BIOS for the wrong board will not help — or can brick it. The board number printed on the PCB tells exactly which board you have.
Where to look
- Switch the laptop off, unplug the charger and remove the bottom cover. Disconnect the battery.
- Look at the white text printed on the green board — near the RAM slots, under the battery area, or along an edge. Some boards also have a sticker with a barcode.
- Note the code and the revision next to it (REV 1.0, R2.0, -A01). BIOS dumps should match both.
- Search the code here. Try without the revision, or just the digits, if nothing comes up.

Tips
- Search partial codes: 7912 finds LA-7912P, LX6 finds DA0LX6MB6G2.
- Check the revision before flashing a BIOS: REV 1.0 and REV 2.0 boards can need different dumps.
- Phones: search by the model number (for example SM-A515F) — it is in Settings → About phone.
