    Hi Sorin, I've been buying scrap laptop motherboards and laptops without screens etc to practice on. I have a power supply so I can power them up. Unfortunately most seem to be working ok, but stripping out a motherboard from a shell without a battery, ram, hard drive or a screen and just watching the power supply react as i try to find and short the power button is educational. Weirdest thing so far is a board that works, but I saw 18v on the supply to the positive pin for the on switch and the board wouldn't come on. It reverted to 3.2v and would start normally. I would highly recommend buying scrap stuff from ebay and trying to find the problems and solve them. As an educational tool, they are cheap, it doesn't matter whether they work again, and they have useable spare parts. Win, win. Thanks for what you do, I would also recommend followers of your work to listen to your words more than use their eyes. You say things that are very important if someone is learning that are second nature to you. Much love ❤

      But they suck if the keyboard goes kaput due to liquid spill. Can't easily & cheaply remove / replace keyboards. Junk. Some other jobs on the superslim stuff sucks as well

    • @spongerobert
      @spongerobert 5 месяцев назад

      @@daffyduk77 Yeah, all the new laptops are doing that now with the keyboard not being a removable part but a thing under the plastic so you need to strip the whole laptop to replace it. Most Lenovo ThinkPads (maybe all of them?) still have a top removable keyboard. Old Dell Latitude and Inspiron had that but all the new ones have the keyboard under the cover. On Lenovo Ideapad the whole top cover with keyboard and trackpad is sold as 1 part so if you need to replace the keyboard they want you to replace the whole top. Lenovo ThinkPad, Dell Latitude and HP Probook are the best built laptops for business in my experience with HP being the worst of the good ones (lots of thin plastic and crap cooling)

    • @spongerobert
      @spongerobert 5 месяцев назад +2

      Both of those are really bad lessons tbh. Dell is expensive (2nd hand parts are fairly cheap for old Dell laptops) and they're too smart for their own good with various chips doing nothing but making things complicated plus I have seen literally 100's of Dell laptops spontaneously rejecting an original Dell charger and then going in to a "protection mode" where it runs at 20% cpu power and then best case scenario you need to get a new charger but usually it's a chip on the motherboard that dies because they have some dumb "charger verification" crap that pirate chargers circumvent anyway.
      Also, AMD Ryzen laptops are extremely good value for money with more cores on a CPU within the same price range. I recently ran a barrage of teste on a 12th gen i5 Lenovo and the exact same model but with Ryzen 5 cpu and the Ryzen won every time because the i5 had some funky power throttling/heat throttling. i5 Won in short bursts but not for sustained workloads like video encoding or gaming.
