    In that case we faces firsly rtcrst, srtcrst and rtc frequency and also bios faulty, and there also fault of 3.3vdsw and rsmrst is generating?

    Is it possible to disable the 4GB RAM soldered on the motherboard so you can use a 32GB stick in the SODIMM slot?
    I'm currently using 20GB with a 16GB stick but it would be nice to upgrade to 32GB if possible.
    I think the max RAM is 32GB so 4GB on-board + 32GB stick = 36GB won't work. Right?

    • @laptex1377
      @laptex1377  2 года назад

      Yes possible if schematic and boardview is available.

    Sir this old video help me today to resolve ideapad 330s not triggering problem. Problem in this board is rtcvcc is okay on rtc diode but on rtcrst it's 1.4v instead of 3v. Track of rtc is internally leakage . After jumper from rtc diode to rtcrts resistor board start triggering. Thank you very much

    Sir that replaced IC has a hole in it. I have a similar board with no lights nothing but 19v is present. Had a bad charger that caused the 330s to go off. Any suggestions plz? Checked mosfets and caps. Not found any shortage yet

    Hello, I have an issue with the same PC and Motherboard. The PC suddenly stop working. I check the power voltage directly on the power connector (without to be connected to the motherboard) and I have well 19v.
    When I connect the connector to the mother and check the power value on the slot near the connector (+) I have only 0.4 v.
    No light is switching on. I did the test with another power supply: same issue. I removed the battery, RAM, disk... same thing
    Any idea? Thanks for your help.
