  1. System: Windows 10 Home
  2. Battery or AC: Battery
  3. Model: Asus zenbook UM425IA
  4. Frequency of occurrence: once per week
  5. Reset OS: I did not try
  6. Screenshot or video: unfortunately I don't have any video, next time that will occur I will record one.


Detailed description: Sometimes my laptop won't charge.. (it's showing that it's charging but it's not), I tried reinstalling the battery drivers but it won't help. Only way which helped was restarting the laptop several times and on the 5th time it worked. (this happened like 4 days ago for the 3rd time or so.) When I ran the MyAsus hardware diagnostics it showed problems with adapter. After restart everything was fine.

The battery indicator on the left was blinking.


This issue: https://zentalk.asus.com/en/discussion/comment/112451#Comment_112451 The led next to the power button was also blinking.

Here is screenshot... I did get this problem now also when the battery is charging.

+ I did get the battery problem which never happened before

    i have the same problem as the threadstarter, same model um425ia, a windows update made somewhere last week started to give problems in charging since last tuesday 15 Sept. the asus bios update was also launched during the update but i continued by clicking ok. my serial number is L7N0LP021274305, after running the hardware checkup, it says there may be a issue with the adapter, but the laptop was just bought in 6 Sept.

  • Hello @windtreader ,

    Please update the BIOS I send your in the PM.

    And also update MyASUS v2.2.36.0 & ASUS System Control Interface v2.2.28.0 from Windows update/ My ASUS update or from official support website for the diagnose tool issue.

    Thank you.

    Hi Blake, i managed to update my bios using the bios installer for windows from My ASUS, it managed to solve my battery charging problem, without using the BIOS file you gave me, will keep using this BIOS version.

    if i were to use your BIOS UX425IAAS.306, do i copy over the file in the BIOs installer?

    i was able to find the MyASUS v2.2.36.0 from the microsoft store and ASUS system control interface v2.2.28.0 from the official webpage

  • Hello @windtreader ,

    The one I send you is the same as the "BIOS for EZ flash Utility"

    Thank you.

  • Hey @Blake_ASUS

    I am using UM425IA and just received this laptop on 1 October. I have the same problem; orange flicking LED light when charging. I tried to download the BIOS file but I am unable to since my battery is below 20%. What can I do?

  • I bought this laptop on the 28th September and am having the same problem. How do I solve this?

  • Hi,

    Then...you may plug in the adapter and then wait until it is charged over 20%?

  • HI there @windtreader , may I ask if your zenbook is the one with the Ryzen 4700u or 4500u? I think I may have exactly the same problem as yours.

  • Hi,

    I have the same problem on UM425IA

    I know that i must upgrade to bios 306 or higher 307.

    I downloaded this bios.

    But when PC reboot and i enter in BIOS and EZ Flash 3, although i put my USB key formatted in FAT32, the bios UX425IAAS.306 and the usb key are not seen by the system and i can not upgrade.

    Why this EZ flash 3 i unable to recognize this USB key ?


    PS : In Windows, i see also that device System Firmware is not working correctly and give CODE 14 or CODE 10. And asking details on it, it says UX425IA.307 in pilote details at end of line and driver version is
