Hi Nitishk23,
When exactly does the system shuts down?
Is the battery able to hold charge?
Please check the Battery Health Meter:
- Right click on the battery icon on the taskbar
- Choose ‘Dell Health Meter’
- Click on ‘Battery Health’ tab
- Examine the information shown in the window. Please check all the tabs
Would also suggest you to check with an alternate battery (if available), if you experience the same issue.
Please reply if you have any questions.
