    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…

    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

    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….

    I can't find that mosfet anywhere (except from china). Is there an equivalent I can use as a replacement?

    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.

    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
