    fixed my rtc failure by doing a power drain. and clearing cmos via clrp pins. I removed the battery cable. Pressed power button for 1 minute holding it.
    I cleaned/wiped the gold/cooper contacts with Alcohol.
    Shorted/put a jumper to connect the pins to reset/clear cmos. I did this for 1 minute. Then i left the laptop and had a shower. Came back did the same steps. Connected everything including ram like all that is supposes to be connected. connected the psu then turned on the laptop. The sign that cmos is really cleared is the laptop will turn on led lights on no screen. will auto turn off and do this cycle twice. after that it will display a screen RTC clock not set. All done and sorted. Hope this helps. Im using a monile phone and english is not my first language so bare with me.

    Miraculously fixed it.. Thank god. I did this process earlier and maybe i was rushing which is why cmos was not cleared properly.

    Thank you much for the post. I was reading your posts through a search and appreciate the follow up.
    I will add this to my list.

    it would be helpful to understand if I have a catastrophic problem or not.

    I tried this with no luck.
    I am getting two errors by watching the lights:no ram detected and cmos battery failure.

    I had that as well earlier. First light indicator was
    2 red and 4 blue which means RAM FAILURE then after that 3 red and 1 blue which means RTC power failure/CMOS battery failure.
    What follows next is just the CMOS battery failure light indicators and no more for RAM.
    One of the step I did which I did not mentioned as I don't know if it is relevant for the fix was - Removing the battery cable - Remove RAM - Clear CLRP - Plug the battery cable again - Turned on Laptop - Let the light indicator for the RAM FAILURE do it thing - Suddenly after that I PUT 1 RAM Stick in.
    This steps did not fixed the entire problem but it fixed the RAM FAILURE because after that no more light codes for RAM FAILURE.
    Next thing I did is what I mentioned previous post but I failed to mention something which again I thought was not relevant.
    I also did remove the CMOS cable which is next to the 1st SSD slot by using a plastic clipper. Did the power drain steps again. Left the laptop for approx 30mins. Came back and did the same process where pressing the power button for 1 minute draining power. Then also shorting the CLRP pins for 1 minute. After that I put everything back in and power it on with the PSU connected as well.
    This is the whole steps that I think I did. Sorry for less information earlier as I was using my mobile phone and also you did not mention or I missed the RAM FAILURE lights you had as well.
    I really hope this will fix your problem.
    RTC power failure as far as I am aware is fixable compared to a beep code CPU/GPU failure.
    Also I am not an expert. I am just sharing what I know and hope this will help.
    Edited:
    Place I got to know the error light codes.

    Errors defeated with tips from 0lok.

    However now when it boots, nothing populates on the screen and it sits and runs for about 2 min then shuts off. The fans run higher and eventually shuts off. I tried booting holding Fn with no luck.

    I think I mentioned it earlier that it is normal. It is a sign that cmos has been cleared properly. All you have to do is be patient and really wait until it finish its cycle on and off until you will have a screen display. Mine did it twice or three times the cycle on and off after that a screen display.

    reread and it seems 2 minute is quite a long time l. mine was approx. seconds only like 5 to 10 max then shuts off and repeated the cycle twice or three times then had a screen displayed.
    I don't know to fix tge problem now. more googling and wait for other members to help.

    It’s definitely not restarting. It’s pausing.
    I greatly appreciate your assistance. It appears you tackled the first two problems for me.

    Does anyone have any feedback on no boot, no display, fan running for a couple minutes and then turning off?

    You have to disconnect the CMOS battery for a long time and then CLRP trick works or you can flash full SPI dump of working BIOS to revert to factory defaults.
