We have repair succesfully the DC plug for an customer, but after it we only got black screen when turning it on.

We are unsure if it's a hardware fault, testing with memory/storage/battery/CMOS battery turn not be succesfully to find the problem.

Is there any possiblity to find the error in de bios file and correct it? We have try a different bios on the website. But that was not a succes.

Is there someone that maybe could help us?

Spec:

model:N18Q13
Aspire 3 A315-57G-78SP
SN:NXHZREH004118010FC7600

Thank...
