I had an iPhone with a dead battery. I was trying to charge it in a very silly way using my MSI 63-thin laptop. I cut the charge cable and tried to connect the red and black wires to the phone's battery. Suddenly, the laptop turned off. I tried many times, but now it won't turn on in any way. Repair guy is saying that after checking there is no shortage in graphics and pricessor chip, but the IC KB9548GF2 has short circuited and needs to be replaced. My question is, is it repairable or not, because this IC is not available in our country, and I will have to order it from China.
