how did you solve

I repaplace U7400 SLG4AP645AV in this case.

@@jrepair5543 thanks for the reply man. You don’t know how desperate I am to repair this laptop. Could the chip be called u4700? That’s the only one I can find on eBay. Thanks for your help man. Very much appreciate it

Yes ofcourse.

@@jrepair5543 I wanted to consult my macbook, the same thing happened to your video, my question is in the battery screw there is a plate that I lost, can I install the logic board without that plate and placing the screw directly?

@@jonathanariel7225 Yes you can use only the screw without small metal plate.

@@jrepair5543 Thank you very much for your answer, if you do not mind I wanted to ask you one last question, in my case I bought a logic board (how long do you think it will last me without having any problem again) Do you recommend that I change the logic board following the steps in your video? thank you

@@jonathanariel7225 if you use original charger and the macbook used at flat surfaces not beds etc for avoid thermal to lo logicboard ( remember that logicboard not have fan) i don't think have any problems. The most important is the charger must use original Chinese ones cause damage to logicboard.
