Hi @sohammaity
Create a [https://www.groovypost.com/howto/generate-battery-report-windows-10/|battery report] to find out the charge status of the battery.
When you have the report, compare the ''Design Capacity'' value versus the ''Full Charge Capacity'' value and check what percentage the Full Charge value is of the Design Capacity value. If it is <40% you should consider replacing the battery.
If you determine that the battery needs replacing, here's the [http://h10032.www1.hp.com/ctg/Manual/c06242992.pdf|maintenance and service guide], taken from this support [https://support.hp.com/us-en/product/hp-14-dk1000-laptop-pc-series/32591219/model/34443567/manuals|webpage] for the laptop model.
Go to p.35 to view the procedure to remove/replace the battery.
At the top of p.35 you will find the part numbers for the 2 compatible batteries that may be used in the laptop. Search online using the ''part number only,'' to find suppliers that suit you best.
