A particular model of a laptop computer has many configurations and there are also some differences. Next, I will guide you through the process of finding out your motherboard model and making a selection.
- The first method is to check the model number printed on the back of the laptop, which is the simplest way to locate it.(The search results are most likely for the entire device, not the accessories.)
- The second type is the board number on the motherboard,These numbers composed of letters and numbers are the model number of the motherboard.By referring to this model, you can determine the parts that need to be replaced.（It should be noted that the board number cannot distinguish between CPU configuration and graphics card configuration.）
- Confirm whether your motherboard has an independent graphics card (the cooling fan structure is different and it cannot be replaced)
- The replacement of the motherboard must be carried out strictly in accordance with the requirements; otherwise, it will result in the device being unusable.(Both the CPU and the graphics card can be equipped with different configurations. However, it is important to distinguish between Intel and AMD.)
- If you want to find an exact replica, you can look for the sticker on your motherboard. The numbers on the sticker represent the precise configuration number.（This kind of number may not be searchable because there are too many motherboard models, and many search engines have not included this number.）
- When searching, you can also try entering the letters and numbers directly without punctuation.（If there is a very long one【NB********】,Just select the first ten digits will do.）
- Similar to other numbers [******-601] [******-001] are also the same and can be searched for.
- Dell The QR code on the back shows "DP/N" Just select a six-digit number followed by a letter.
- Lenovo can view PN: 5B********（Just search for the ten-digit and letter combination number of 【5B**********】）
- The best way to find out is by checking the motherboard serial number. Then, you can contact the customer service for further inquiries and recommendations.
