    Asus ROG G513QC liquid damage

    Hi!

    I have an Asus ROG with some liquid.
    I already replaced most of the damaged components.
    But there are some resistors that have OL resistance but i don't have the exact value to replace them.

    In boardview it carries a signal called VRAM_DGPU_TON.
    First is 2.2 Ohm 5% (R67218)
    Second is 499K Ohm 1% (R67217)

    also R6016 Measures 210k instead of the 130k in boardview.
    It's part of AC_SHORT_DETECTION circuit.
    Should I replace that?

    I have 1 ohm, 3.3 ohm, 100k, 470K resistors.

    Is it OK to use those or should I get resistors with the exact value?

    Any help would be appreciated.

    Suggest to get the true value indicated in the boardview file. Use 1% tolerance.

    You will also need to confirm the physical SMD size of the part. Popular sizes are 0402, 0603, 0805. Cell phones / ipads will use 01005, 0201 - these are very tiny buggers.

    The proper size is required so that you can solder the tips onto the SMD solder pads when they arrive. Suggest to source from Digikey / Mouser or Arrow Electronics. You may be ok with RS electronics in the UK.

      For test purpose,you can use
      01. 3.3 ohms instead of 2.2ohms
      02.470k for 499k
      03.100k for 130k.

      make sure you're reading the resistor out of circuit before going for replacement.

        Thanks for the answers.
        I will order the parts and update after i replace them.

          HI!

          I have replaced all the parts with correct value replacement.
          Now i have 1.69V on the ACDET pin.
          And the main power rail is now shorted.
          I checked the coils the battery charging circuit is shorted.
          I removed the mosfets the short is gone one of the two was shorted.
          Now the main power rail is 20V and ACDET is 2.69V.
          What could cause this? I will order new ones, will they blow up too?

          Sorin had a video with almost the exact same issue. He couldn't figure out it either.
