    WP_20151108_004.jpg Help!
    I was using the laptop, but recently i have noticed a burnt smell after some hours of use. I removed everything from the laptop and this is what i noticed.

    This burnt area is the same one as the one from this topic http://forum.notebookreview.com/threads/m18x-up-in-smoke-with-pictures.753394/

    The laptop is not dead yet, only some random restarts but thats it. However, I dont think that will last for long. Is there anytjing I can do to prevent that area from dying? Likeadding thermal pads, undercloking or electrical tape?

    thank you.

    UPDATE: Burning smell starts to appear only when the laptop is plugged in. On battery it works great, however, the battery doesnt get charged anymore. The adapter doesnt turn off auto. when I connected it to the laptop, and the laptop power off button changes when I plug it in; however, the battery doesnt charge and it turn off as soon as I disconnect the battery.

    Guess I have no choice but to replace the mobo.

    The slightly burned components are switching mosfets - any reasonably competent electrical tech should be able to swap those for new ones without having to replace the whole board. The key is to get it fixed now before it gets very hot and actually causes real damage to the board itself. Personally I have replaced these components many times in the past.

    Thank you for that, I was really hoping an alternative to the one when I have to replace the whole mobo. I make some research about those mosfets and this is the part number that I have found: AOD403 MOSFET. Is that the right piece, or is there something else that I need to look at? Any tips for the procedure?

    Hope that the chips just run out of life and there is not something else that is causing those chips to burn.

    As suggested - stop using it and repair it ASAP! The alternative is not really an alternative, since sourcing a good board would be a painful and VERY expensive task (you'll return at least one board in the process). Have you ever soldered? If not, better find a repair shop and ask them to replace these components.

    Ya, that's what Im doing, I am using a rented laptop for now. I already purchased the parts, they might come next week. I do not have much soldering experience, so I will prob ask someone for help.

    Prob it cant be seen that well from the picture above, but I think that the heat from the CPU melted the solder from those chips, which caused them to fail... at least that is what I think happened.
