    Asus Zephyrus GX501gl fan issue

    Was working fine until I had an issue with the GPU and CPU fans. They were very noisy, I bought new fans from Asus Europe. I installed them, they worked for about an hour, then nothing, the touchpad, and RGB also stopped working, any help would be very welcome.
    thanks

    You have tell us a very few info...
    Have you ever before replaced the fans on a laptop?
    Did you remove battery connector first, before replacing?
    When fans stopped working...did touchpad stoped working in that moment or later?
    Besides backlight is keyboard and usb working?
    Can you read voltage on fans connector to motherboard?

      do you happen to replace the whole cpu heatsink with fan or just the fan? have you placed fresh thermal grease on the heatsink? if you remove the heatsink it is advisable to put fresh thermal grease.

        thanks a lot, turns out when you remove the heatsink it requires you to replace the thermal paste, there's a sensor near the cpu socket that detects when you remove it, and disables the fans till you replace the paste, a bit odd but it worked, i never seen something like that, I always got away with that

              ASUS Zephyrus GA401I Severe Lag, Suspect Motherboard/Power Issue - Need Help Diagnosing
              by MakNCheese
              Hi everyone,

              I'm having a serious issue with my ASUS Zephyrus GA401I (4 years old, worked perfectly until recently). The system is lagging heavily, even in the BIOS, and is charging extremely slowly (a few percent in hours), making it nearly unusable. I suspect a motherboard or power delivery issue.

              Symptoms:
              • Severe lag across the system, including BIOS navigation.
              • Slow boot times and unresponsive performance in Windows.
              • Battery charges very slowly (e.g., ~5% in 2–3 hours).
              • No error messages or BSODs, just extreme sluggishness.

              What I've Tried:
              • Replaced
              ...

              Asus ROG Zephyrus G14 GA401IU-HE103T GPU Nvidia Issue
              by tech_guru
              Hello all,
              I am having an issue with this laptop, on which I repaired the motherboard on other power issues (PMIC, mosfets etc) and it came back to life, but I am having problem with the GPU NVIDIA GTX 1660. It gets error 43 in device manager with exclamation mark and does not work. When I install official asus driver or official nvidia latest, the error goes away until you reboot the laptop, where the error comes back again.
              GPU-Z software does not show many information and vbios info is missing (photo attached).

              Because the customer sent the laptop to 2 other labs trying...
