    Hello, I'm new to the forum, but I have been following it for some time. I seriously hope someone will be able to help me.
    Here is my problem: I bought a new ASUS laptop 3 months ago, and it was all okay until it started to shut down on its own ( about a month ago). I tried resetting Windows, updating etc then I replaced my hdd because a software diagnostics tool reported that there were bad sectors. I could also hear strange noises. I read that manhandling the laptop while it is running could damage the delicate workings of the hdd, and I had done that sometimes. Everything was fine for almost a week, then the computer started shutting down on its own again. It happened while I was working , keeping multiple programs open (twice, hours after turning it on) and while I was watching a video (10-15 min later). However, today was not the first time I watched a video, so the issue is new. It seems like it is gradually worsening. After it shut down, I tried to power it back on, but it wouldn't boot. The LEDs didn't even turn on, unless it was plugged in. When i unplugged the charger it shut down again immediately. After 3 minutes I removed the external power supply, and it kept running.

    I have already updated the BIOS firmware to the last version, but it obviously didn't work.
    ASUS PC Diagnostics tells me that the CMOS pattern test failed, I looked up possible solutions, but I wanted to ask before doing anything stupid.
    I am pretty sure it isn't a heat issue, internal temperatures are within range and the laptop feels cool anyway.
    What worries me the most is that this guy is just 3 months old, and it already has so many problems.

    If you bought that ASUS VivoBook Max X541UV laptop in brand new condition 3 months ago, it should still be under warranty.
    Unfortunately, by tampering with it and replacing its hard drive, you probably voided its warranty.

    I'm not a hardware or diagnostic expert, so be patient and wait for one here to reply.

    Thank you for replying. Yes, I am aware that I probably voided the warranty, even if I haven't broken any seals, this is why I would like to find a way to fix it by myself before taking it to ASUS
    Anyway, it's not VivoBook, it's F541U

    You almost undoubtedly have a defective battery; though, if it gets totally discharged, it may need 12+ hours on the AC adapter to fully recharge it.
    It should; though, have gone to sleep instead of rudely turning off. Are you sure it doesn't say "resuming Windows" when it does this?
    Get a copy of BatteryInfoView and see what it says about the battery when it is most of the way fully charged. It should say designed capacity and current capacity which should be somewhat accurate.

    If it shuts down when it has a decent charge on it, you should pursue a warranty replacement from ASUS and just don't tell them you changed the hard disk drive.

    Your TSGSIU log identifies your laptop as an ASUS X541UV - which is a VivoBook Max model.
    https://www.asus.com/Laptops/ASUS-VivoBook-Max-X541UV/

    If your laptop is actually an ASUS F541U model, I can't locate a support site for it.

    F541U is the name written on the label near the touchpad, I don't know if that matters if the motherboard is X541UV

    Yes, I'm completely sure it doesn't say anything. When it shuts down, it is like someone pulled the plug while a desktop computer is running, it makes the same static noise.
    This is the log of BatteryInfoView, everything seems alright

    Do you think that the failed CMOS pattern test has something to do with this?
    Thank you for your help

    I forgot to specify that as long as the laptop is plugged in it works normally, without a hitch

    Thanks for finally mentioning that.
    DavisMcCarn's suspicion about a defective battery appears to be right.

    Its either the battery or the power management circuitry on the system board. Whatever you do (!!!) keep ALL of the original parts if you replace anything. I hope you still have the original hard disk drive.
    Here is how to replace the battery:
    https://www.ifixit.com/Guide/Asus+X551CA+Battery+Replacement/24928
    And this looks to be a genuine ASUS replacement battery:
    http://www.ebay.com/itm/Genuine-A31...777092?hash=item238ba62604:g:34oAAOSwA8VZlQlV
    As a note, the F541 is a different model but is part of the X541 series.

    Thank you for everything, and sorry for replying so late
    First I am going to see if my warranty covers this, otherwise I'll replace the battery on my own
    Anyway, of course I have kept the HDD

    My worry is that the problem may be (less likely; but,...) with the system board (most folks call them motherboards) in which case you'd be silly not to put all of the original parts back in and then invoke a warranty repair. ASUS' customer service rating has gone up a lot in the past few years.

    Yes that is what I thought before as well, and your opinion makes me more convinced of it.
    I'm a bit confused as to how I could have damaged it, I am more inclined to think that it is a manufacturer defect

    It is still far more probable that the battery is defective.
