Hi @abhinabasharma
It may be that the battery is starting to slowly fail and can no longer maintain its charge as it did before, so the laptop hardware is struggling.
Create a [https://www.windowscentral.com/generate-battery-report-windows-10|battery report] to check the condition of the battery.
When you have the report, compare the ''Design Capacity value'' versus the ''Full Charge Capacity value'' as seen in the report. For a good battery they will nearly be the same value.
You can determine the condition of the battery as as percentage by using the formula ''Full Charge Capacity value x 100 ÷ Design Capacity value.''
If the percentage is <35% you may consider replacing the battery.
If you decide to do this, here's a [https://www.youtube.com/watch?v=c0T3Cj9vCAo|video] that may help.
Search online for ''0B200-03270100'' to find battery suppliers that suit you best. This is the Asus part number for the battery. It should be located somewhere on your battery if you wish to verify.
