Solved! Weird battery problem

I have a problem with my HP 15-r249tu, windows 10 laptop. It needs to be plugged in to start, after that if I unplug, it works, the battery icon show empty, but clicking on it show's 100% battery.

Earlier I had a different battery issue, when ever I charged the battery and it shows 100%, fully charged, I unplug and the system would shut down. Only after plugging it in, it would restart, then after it would work even when unplugged. SO immediately after charging, on unplugging it would shut down. No problems after pluggin and restarting.

I contacted HP support and the support, did some troubleshotting steps but did not solve the problem.

Now I can not start my laptop without plugging in. Also the laptop does not shuts down like before when unplugged. The HP support were of the opinion that battery needs replacement. But I dont agree, as ican use the system for a few hours after unplugging, and the problem started after some times of ungrade to windos 10. (No option of going back to win-7)

My laptop has the old UEFI with no component option, so I will download new UEFI from HP site on a USB and run the test. However I did run the test using the HP assisant yesterday itself, and the result was Charging (67%), Primary battery OK(0). cycle count 197/300, design capacity-1692, full charge capacity-1692, remaining capacity-1125, current-1723

But today running the same test showed Unkown-Primary battery unknown(90), HP battery was unable to access the battery, PLease shut down the PCand reinsert the battery and AC adapter. Please verify that you are using the latest version of HP battery check and the latest BIOS version.

During my previous communication with HP UEFI test were run and it was also found ok. see below

Battery check: did not progress 1%, waited for 10-15 minutes, but justdid not move beyond initiall 1%, so stopped.

After I restarted, the icon show empty, plugged in but not charging and clicking on it shows battery at 100% fully charged.

I unplugged the system and have been using the laptop for 3 hours and 40 minutes now on battery.

This is not a faulty battery issue, but some software issue.

Kindly find some solution. I have tried to uninstall and reinstall the battery drivers, remove the battery and reinsert it, it works sometimes, but then again the same problem. Every time I need to start the system or re start after shut down it need to be plugged in.

BIOS version/date-Insyde F.40, 7/26/2016
SMBIOS version -2.7

The above BIOS was updated by the HP support, but did not solve the problem. My model laptop on HP site says the lates BIOS is F.40 Rev.A, I am not sure what to do.
