I installed manjaro in my Acer Predator Triton 300 few months back. I did not like it much as my system temps were peaking up till 70degrees in idle usage. I uninstalled it by deleting all the partitions and removing it from bootloader using EasyBCD. After that when I tried entering into BIOS, it shows me a blank screen with an underscore in top left. I have no other option other than to hold the power button and enter into my windows OS normally. I tried entering into BIOS using the windows advanced settings also but same effect. So that solution will not work for me. Tried reinserting the RAM stick as suggested by some people on internet. Some articles suggested to reinsert CMOS cell. I cant spot out any CMOS cell in my motherboard. I disconnected battery, held on my power button for 30 seconds and tried it but nothing happened(this was suggested by few articles which said that some laptops dont have CMOS cells to power up BIOS and they normally use battery to power up.) All of this is tried by me. Can anyone suggest a fix or tell me about location of CMOS battery in triton 300?

     Spandan yes seems that installing linux in dual boot might break the bios access as i have stated many times here before linux its not officially supported by Acer so use it at your own risk im afraid we cant be of much help on your issue unless some other member here has a fix for it u will probably need a clean install assuming your acer stock recovery still intact backup whatever you need and follow the instructions on the video below good delete everything for a clean install luck :)

    PS: all laptops have cmos battery what they dont have its the battery powerdrain switch which was replaced with the power button on the 2019 and above models only the 2017/18 have it i havent looked at the schematics of the triton 300 yet but your cmos battery might even be on the other side of the mobo under the keyboard as some tritons have inverted mobos which require complete disassembling to access ram and ssd upgrading
