    Really seeking some advice or help.

    I currently have an ASUS UX301LA Zenbook that has been very well taken care of. The laptop recently dies due to low battery and shut off on it's own. The laptop has been shutting off right away and not going into sleep mode at all without any critical warning to plug in my charger when it is lower battery. I would just replug the AC adapter and no problem it would charge and work normally.

    So the computer shuts off due to low battery, I plug the AC adapter in and the charging light (orange) turns on and I try to push the power button but nothing happens. The power button just lights up and then shuts off and the screen remains black. Now when I plug the AC adapter into the laptop the "power button" and "caps lock button" light flashes in sync. I try to push the power button and nothing still happens, it just continues to blink. I have endlessly googled for solutions and similar problems. I am looking desperately for any advice as I do not have extra cash to get a new laptop and need to urgently get my school documents back ASAP.

    This is what I have tried so far.
    1. Removing the battery and pressing the power button for 1 min to get the electric circuit out. Put the battery back in and closed the laptop and tried to boot it up with the AC adapter back into the laptop and still the same blinking issue (caps lock and power button).
    2. I have removed the CMOS battery for about 3 minutes then replugged it in and still the same blinking (caps lock and power button). --- I would like to buy a new CMOS battery but cannot find one anywhere online for my laptop model.
    3. I have removed the battery out and held the power button for 1 min and then left the battery out and then plugged the AC adapter in and tried to boot up the computer withOUT the battery. The same issue with the blinking lights (caps lock and power button).
    4. I bought a new AC adapter charger to make sure it was not my charger that was broken and tested it out and it is still having the same blinking light issue.
    5. I wanted to reseat the RAM but I could not because the RAM of this laptop is soldered on.

    My next guess is maybe buying a new battery, but if the laptop cannot even run with a new AC adapter without the battery plugged in then I think that will not work either. OR maybe I could buy a new CMOS battery for the laptop and see if that is the issue, but I do not know where to get a reliable one that is identical to my laptop's model.

    I am afraid there is something wrong with the motherboard and that this is the end of this laptop. Does any have any other suggestions or suggestions I could try, I would love to revive this laptop, it was functioning great before this happened. The only issue I was having with it was the laptop would just die and not give me a low battery critical warning before automatically shutting off.

    The computer is no longer under warranty is it about 3 years old.

    The mainboard could have been damaged or short-circuited due to various of reasons because of the power issue. The system should at least function without the internal battery but it still behaves the same way whether the battery is connected or not.
    You can request for OOW RMA (Out of Warranty) request with ASUS and see if they are able to do this for you or not.

    Hey thanks for the reply, I guess my best bet is to try and call then correct? I hope it won't cost too much, this has been a great laptop.

    Yup, try to give them a call and find out what options you have. It may not be worth it though.

    It looks like I will need a motherboard replacement. Do you think it's worth chipping out $200 - $300 for a motherboard and install it myself?

    I have personally never done this before, if it's known to be a hard task where I could ruin the computer maybe I should not do it.

    Motherboards can be a bit tricky. If you have any static build up you can short out the board again. I would personally leave it to the professionals if you have any misgivings.

    If ASUS repairs it for you, they can at least provide you with 30-day warranty on everything so it's up to you whether you are comfortable of doing this on your own or not.

    Yeah I am going to just take the laptop apart and sell it for parts. I was hoping to sell it because I don't use it anymore :(

    I think ASUS would probably charge me a ridiculous amount to install a new motherboard.

    Those batteries are generic; any CR2032 size will do.

    Would be unusual for a system to refuse POST just because of a dead cmos battery, but if the bios tinkerers were having an off-day and had malicious intent against their end-users then it is indeed a possibility. For $0.92 it isn't that much of a financial risk anyway. Could also measure the voltage of the battery, of course; ~2.8V would still be acceptable.

    However, think your best bet is to research what this led-blinking combination actually means. To be sure; it isn't random. Something caused the system to halt during post and that particular stage has a particular led and/or beep sequence. If there's no proper documentation for this exact system then look for other Asus models from roughly the same era; they'll all use the same combination.
