[Gaurav0224]

Hey HP Community,
I replaced my HP pavilion power 15-cb518tx's old battery which was died, and after replacing this new battery, it wont charge after 64% during first boot up after fully discharged and than i use my laptop for a while and again put it to the charge it will always goes for only 70% charge in windows 10 and if i on virtualization it will maximum go upto 80% and if i charge from ubuntu OS than it will charge upto 84% .....
And it automatically shuts down when battery is below 30% by saying that battery low
And sometimes miracle happens and its charge upto 90%....I dont know what is the problem.....and when i fully discharge battery and i turn my laptop on, it shows cmos checksome error, BIOS version is F.41

This is the command (powercfg /batteryreport) result:

  I wonder if anyone helps me out because it is so disturbing for my college IT studies ...i have to charge my laptop after every 1 hour of basic use such as running visual code. 
  
  
  And i also want to add ram and SDD .....is crucial 8 ram and Samsung 980pro NVMe M.2 is good for it?
