    Hi there , i have a question how did you connect your power supply in to your mainboard ?? please in your next video show us for details.. did you use normal charger connect to mainbaord ?? how did you use the power supply and inject the power in to mainboard !! because you just showed the voltage in drop to 2.95 thax

    hi there, this video has been a great help. is it possible to get a copy of the schematics to obtain the specifications of the capacitors?

    • @northfixtz

      Yeah its possible if schematics for a particular model is available,some model doesn't have schematics so i replace a cap from same voltage rail .

    Could you explain the method to identify the damaged CAP when you spray with liquid the component? What do you see in the CAP? Which liquid do you use?

    Great video, but is it recommended that we just use the PC without replacing the capacitor you removed?? What are the effects on the computer when the capacitor is absent.

    • @northfixtz
      @northfixtz  Год назад

      You have to read functions of capacitor on circuit you will understand better

    Hi , i have a question at 01:09 ,You spilled some alcohol on Ceramic Capacitor , they were 19v Main Power Rail ? thnx

    • @northfixtz
      @northfixtz  2 года назад +1

      By experience most of big caps lie on the 19v (main power rail)so if the main power rail short to gnd most likely i check capacitors first...thanks

      Can you check voltage on the fan connector ,,you can reset by removing Cmos battery may be it will work,,,is also fan new?

    Hello sir, I have a problem with the same lenovo T420, it won't turn on when I press power. On the PSU the ampere is also not moving, if the cpu chipset is installed the ampere does not move, and a lot of short capacitors if the cpu is not installed the ampere goes up 0,16A and the capacitor that was short becomes not short and the area is warm on the U5 chipset, what should I do, thank you very much
