Detailed description:

Recently, perhaps the past two or so months, I've been having issues with the laptop's battery life and it's been very noticeable in the past several weeks.

I also notice that when I am using it and plug in the AC, it makes a very loud noise as the fan begins to rev like a 900 HP Mustang GT. I'm a very busy student so I would like to avoid sending it off to repair unless it can be made within the week, but I'm not sure if this is necessary at the moment. Any tips? ANy help would be greatly appreciated.

*I have the battery and energy reports from a couple of days ago but the file type can't be posted directly on this forum, but I can easily provide it.

**Also, this may be unrelated but earlier today my screen completely froze and I couldn't use any button on my keyboard or even get the display to turn off...had to hold down the power button for a minute or two to get it to power off [I assume this is a separate issue but I'm really not sure]



  • Hello musto,

    Please kindly check if your BIOS and Windows have been updated.

    Thank you.

  • I believe I updated my BIOS recently, the current version I have is:

    BIOS Version/Date: American Megatrends Inc. UX433FA.310, 2019-10-14

    If there is a more recent version, please let me know and direct me to a download link

    Thank you

  • Hello musto,

    How about windows update? and does the issue get better after update?

    You may put space in the link you want to share then you are able to post it.

    Thank you.

  • Yes, my WIndows is also up to date, but the issue still persists.

    - Also, what link did you want me to share? I wanted to share battery and energy reports which are .html files but I don't think this file type is compatible to be shared here?

  • Hello musto,

    you can either attached the file here.

    or you can upload the file to google drive or other cloud, and share the link here.

    Thank you.

  • I wasn't able to directly upload the link, so I've attached it via a txt file.

  • Hello musto,

    For your battery, it's pretty obvious that your battery has been aging, it has been through quite a lot of cycle, so the battery life is decreasing.

    Please disconnect the adapter and long press power button for 40 sec.

    Also, enter BIOS to load default setting again.

    For the fan issue, please run the diagnostic tool in MyASUS, and is there any abnormal sound other than the spinning sound?

    If there is any freezing issue, please let me know and describe what you are using at the moment.

    Thank you.

  • Hello Blake,

    How do I resolve the issue then if it's a matter of my battery life (which btw, it's only been slightly over a year since I bought this laptop)? Do I need to get a new battery or something?

    I entered BIOS and loaded default settings, but the battery still seems to be draining rather quickly.

    There aren't any other weird sounds it's just very loud usually when I plug the AC in.

    The freezing issue was more of a one-time occurrence I believe. But the touchpad does seem to slow or freeze every now and then, to resolve that I normally disable it for a few seconds and then enable it again, which works pretty well.

  • Hello musto,

    The battery went through more than 500 cycle, that is a lot. Please refer to below article.

    If you think that the battery life issue troubles you, then you may change one.

    When the AC is plug in, the performance of the laptop increase and the heat would goes up, so of course the fan would spin faster and become louder.

    It became louder than before could be that there is dust in the fan or the heat radiation of the laptop is also decreased.

    Maybe it's time to back up your data and reset? to have a fresh start? the freezing issue could be related.

    Thank you.
