Laptop Suddenly shutdown at battery 70% sudden drain

[KaranGulista]

Hi

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.

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 evey 25% battery drain means after half hour battery backup only.

Kindly help if someone knows.

When you do the battery check in UEFI diagnostics (F2 as you power up) how many cycles does it say are on the battery? 

1.5 years is a bit of a short life but it depends on how much the battery has been charged and discharged.

Presently in Battery test it showing 49 cycles.
