  1. I have one mosfet burned out in my motherboard. Its a NIKOS P60N03LDG QNA7LOMO3. Now do i have to change it to the same one, or i can use some other?

  2. If you know how to solder the video showed you what you need to do it. Now the soldering well I cannot teach that. It is like teaching a baby to be a cardiologist…

  3. I have a dv4-2040us does no power with fully charger battery or AC adapter. Charging indicator comes on but once I press power button power led and flashing indicator flashes once and then charging led goes off on charging port. Please help. I already reseated everything, tried different chargers, pressing 30 secs power button without battery and nothing seems to help. Any suggestion will be appreciated, thanks

  4. I am getting 19.5 V on the charging jack, but as soon as I plug it into the port on the motherboard it gives me less than 1V on the port… This chip does not have any damage, could that still be defective… please help, thanks….

  5. Can you tell me what is the exact name of that pen like tool that you used to clean up the PCB board? The silver and black one that you said was a precision sander. Thank you.

  6. Hello!

    Could you please write down for me what is the exact name of that pen like tool that you use? Not the "Circuit writer" but the other. And for what do you use it? Sorry my english is not the best and did not really catch on what is it and what is it for.

    Thanks a lot in advance

  7. @coolerester77 I would say it can and probably will. I have seen and worked on 6 in the past 3 months. They used OEM and non-OEM adapters. I think it happened because it failed. This is a emerging fault in my repair operation so I will say it is different than the BGA errors everyone normally attributes to HP systems.

  8. i own a dv4. should i expect something like this to happen to my computer? using the same power cord from manufacturer, why do you think that part exploded?? what is the dv4 known as faulty in any way? great vid…
