Positivo BGH A 450 Power Module Burnt
Hello, I am fixing a computer it is my first notebook repair and i would like to know how to proceed to test multiple components but i don´t know what to look for in a burnt power module (With LAN RJ45 Connector) it seems that the laptop were connected to a wrong power supply, and now it doesn’t show signal of being working. there would be any fuse to check for?? or the procedure to discard as culprit these components? it shows brownish coloured spots nearby solder on the pins soldered to the plug on the board. Also there is like “bumps” on the board near the plug.
The Motherboard doesn’t show signal of faulty components fat capacitors and so on.
Thanks a Lot for any help in advance.
Images of possibly damaged board module:
In the last image it seems that there are no measurement on the component mc3 nor resistance mode neither continuity.
Is this a good question?
