Hi SE.Huzaifa,

Do you hear any beeps from the computer?
Are you able to work on the computer?

It could be an issue with the hardware or software of the computer. To isolate the issue, I would recommend you to run the diagnostics on the computer.

To run the ‘Dell Diagnostics’

• Power off the computer
• Restart the computer, press F12 on the Dell logo
• Select ‘Diagnostics’ from the boot menu
• Please refer to the link if any error code shows up http://dell.to/OUGnqT

 If you are able to boot to the desktop, then update the BIOS of the computer:

Note: Before updating BIOS please ensure that:
*Battery is 10%> or >10% charged
*Battery charger should be connected
*No external devices (flash drives, printers, external hard drives) should be connected.
*All other programs should be closed and documents saved

• Click on the link http://dell.to/RcWyRx
• Click on ‘Download File’
• Check on the radio box ‘Single-file download’
• Click ‘Continue’
• Click ‘Save’
• Choose the location as desktop, save the file on the desktop
• Right click and choose ‘Run as Administrator’
• Follow the on-screen instructions to install the program
• Restart the computer

Please reply if you have any questions.
