When it comes to Apple products, the company usually takes a risk-free approach and opts to replace the entire logic board. While it is possible to replace all Macbook logic board models, this can be quite expensive and is usually a last resort. So, why replace the logic board when you can repair the current one? If your Apple laptop or desktop Mac computer passes the POST test, you'll need to test the hard drive, RAM and GPU. If not, just test the RAM and GPU.
Most Apple Mac laptops have a GPU integrated into the logic board, so you can't take it out to test it on another desktop Mac.Repairing your current logic board is often a more cost-effective solution than replacing it. However, if your logic board is damaged beyond repair, then you may need to replace it. In this case, you'll need to find a compatible replacement logic board for your Mac model. It's important to note that replacing a logic board is a complex process that requires specialized tools and knowledge.
If you're not comfortable with this type of repair work, it's best to leave it to a professional technician. Replacing a logic board can be expensive and time-consuming, so it's important to weigh up all of your options before making a decision. If you're unsure whether or not you need to replace your logic board, consult an experienced technician for advice.
