I am using HP 15 Notebook PC.
It has been only one and half year to my laptop but its battery is not working anymore. It all started with very strange problem when its battery started showing 0% and still running and then it didn’t support charging either and later became dead.
Now I have replaced its battery but still a new problem of sudden shutdown I am facing in my laptop.-Battery suddenly discharged at 50-70% and then laptop starts only after connecting adapter.
Also when I connect adapter, after few minute or so it stops charging and start after one minute. This happens frequently and it takes so much time to charge only 25 % battery from 75 to 100% because battery usually shuts at 50-70% as I said earlier.
Presently in Battery test it showing 49 cycles.
I have tried uninstallation of drivers like in device manager( updating, uninstalling etc.) and battery check hard disk check and all other checks. Everything is showing ok.
But nothing is working. It still shutdown at 70% and now i am using adapter after every 25% battery drain means after half hour battery backup only.

Are you using an HP genuine battery and AC adapter?
Were there any recent windows update on the PC?
Try updating the BIOS to the latest version.
Update the BIOS using this link. Click Here
Try the steps recommended below and check if it helps.
Disable Fast Startup
Right-click Start and open Power Options.
In Power Options settings click on Choose what the powers buttons do option in the left panel.
Click Change settings that are currently unavailable option.
Under Shut down settings, remove the tick from Turn on fast startup (recommended).
Click OK to save the changes.
Check the BIOS to confirm the setting is set to Full Charge, if it is not, change the BIOS setting to Full Charge.
Power on the unit.
Press F10 to enter the BIOS.
Select the Power option.
Full Charge: The battery charge stops at 91~100%.

I tried the steps suggested by you. However, it didn't solved my problem. Then, I diagonosed the battery using troubleshooter which displayed the result as battery to be OK. However, I switched my battery in another HP notebook, the same problem persisted in that too. Therefore, I got a new battery in my notebook which seems to have solved my problem.
