Hi @praveenkuma1062 Here's the [https://download.lenovo.com/consumer/mobiles_pub/e41-20_e41-25_hmm_201802.pdf|hardware maintenance manual] that shows how to remove/replace all of the removable components in the laptop. If you meant fault finding on the motherboard then the schematics will be necessary. Search for ''LA-F971P schematics'' to find suppliers that suit you best.
