CMOS Checksum is invalid ERROR-502 and battery is not charging

[Gtrainer]

Hi, I have a HP Stream x360 - 11-p010nr.  When I turn it on, I get a blank screen.   After several attempts, it does give the the CMOS checksum is invalid...CMOS reset (502) message and then telling me to boot the system.  Nothing happens after that.   The charge on the power cord never goes beyond an orange light (never finishes charging) and once the power cord is removed, the computer shuts down.

I wanted to verify firstly if there is a CMOS batter on the HP Stream x360 - 11-p010n and if there is one, where would it be located?  Assuming there is none for this model, would replacing the battery be the next step. 

Appreciate any help in getting this up and running.

Thank you.

Thank you very much for your feedback.

Firstly, I am unable to obtain the software and drivers, specifically, the BIOS for my HP Stream X360 and therefore could not create a "Recover the BIOS using a USB recovery drive.  See below for details:

I am also not seeing that the stream is getting fully charged as it's getting hung up on the orange light and never goes to white for a full charge.  I am wondering, since i had to purchase a new adapter power cord, if that might be an issue even though the cord is giving me a blue light.   The other issue is if the battery is faulty.   I

So firstly, how could I obtain the bios for this machine if I cannot obtain from HP?

Thank you for your continued assistance.  Appreciate it.

I'm gonna keep trying here.  The issue is not how to update the BIOS, the issue is how to get to the BIOS software.   The HP Stream x360 Convert 11-p010nr is an expired product and I can not download the software!   

Is there another notebook that uses the same bios where I can download the software.  I've never run into this before.  Whether expired or not, one should still be able to obtain the software no matter how old the notebook is.   If not from HP, where??

Your feedback would be highly appreciated.
