Hello! I am new in repairing scenes and currently repairing a laptop Acer aspire e5 574. The power indicator does not light up, the laptop doesn't turn on and the heatsink is heating up. I saw the damaged transistor, I removed it and the heatsink doesn't heat up anymore. So, I am planning to replace the damaged transistor but I can't find the right replacement.

The marking of the transistor is A46v 1A and its part no. is BAT46AFILM.
 
its not transistor its schottky diode. You need to pickup SOD123 package, Reverse voltage 100V or higher, Average current 0,15A or higher, Max forward voltage 0,45V or lower, Peak pulse current 1A.
But if heatsink is heating up, your cpu/gpu is burned or your fan is not working.
if its burned -> game over
 

The fan is not working, I think that's the reason. Thanks for responding! I will update this if I fixed it.
 
OHelo! I have the same problem, I have an e5-574-370m that doesn't turn on, when I opened it I noticed a burnt transistor and it was getting very hot so I removed it, but I can't find a similar one.

OHelo! Estou com o mesmo problema, tenho um e5-574-370m que não liga, quando o abri notei um transistor queimado e estava esquentando muito, então retirei, mas não consigo encontrar um semelhante .

Pbecause I was burned I couldn't read it, I could only see the first 2 digits which is A4, if anyone can help me, I'm very grateful

There is not much what can be do without schematic or knowing part id. You can try BAV70. At you own risk.

Não há muito o que fazer sem o esquema ou o conhecimento do id da peça. Você pode tentar BAV70. Por sua própria conta e risco.
