    I get that same satisfaction when I complete the repairs, I admire those who have that same joy and don't act like it's just another repair. I became a fan of hers and here in Brazil, I say "the job is done" my wife looks at me strangely, what is it, speaking English now😂

Now i know something but i also know that you have nice personality and you are great guy so i wanted to say thanks for your video and educating how to do things. Now i know that some things what i thought are not fixable could be fixed. Also your talks how to behave to people or to customers are very usefull for everyone.

    From most of the times you upload videos about Asus and mosfets I have learned alot about mosfets and what is inside the mosfets. I broke them for fun.
    You dug into this subject and that's how I learned.

    When you repair the motherboard it looks so simple, yet you had at least one thousand devices in your hand so that you can see "the factory flux that came underneath a mosfet" and to actually be sure that's the component that cause problem. Phenomenal usage of tell tell signs.

      By the same logic you should never buy any brand of anything. All brands have problematic models, plus you never know WHY exactly has a device failed. If you have to, at least judge models, not brands. 😉

    • @GaryB007
      @GaryB007 3 роки тому +4

      They sell millions of computers. It stands to reason that repair companies will see more of them. It's the failure RATE that's important, and without knowing failures vs sales, that's impossible to know. How much and how they're used is also factor. Asus are a commodity brand. Buyers of high-end models are more likely to know how to treat them well.

    If you replace mosfets on a badly designed laptop. Won't they just blow again? We don't do board repair where I work...we'd have to charge a couple hundred dollars for a repair like that if we did...no one would want to pay that to repair a motherboard. Keep up the good work and good work on the channel.

    • @coyotex850
      @coyotex850 3 роки тому +2

      a dead mosfet doesn't mean a laptop is designed badly, a mosfet is essentially just a switch, you can have a multimillion dollar house but that wont stop a light switch from failing eventually
