Inspiron 17R (5720) won't boot/POST, no Dell logo, completely blank screen

Hi Chtasm,

Welcome to the Community.

I’d suggest that you follow the steps mentioned below and then follow the next steps to go into BIOS of the system to troubleshoot the issue with the system.

• Switch off the computer.
• Disconnect the AC adapter from the system.
• Remove the battery from the computer.
• Press and hold down the power button for 15 seconds.
• Then connect back all the peripherals and check if you are able to turn on the system.

Please follow the below steps for resolving the issue with system stuck at Dell logo.

• Turn on or restart the computer.
• Immediately at the Dell logo screen, starting tapping the key once a second until the BIOS screen pops up.
• Using the right arrow key move to ‘Advanced’ tab.
• Using the down arrow key move down to ‘SATA Mode’ and press ‘Enter’ button.
• Change the SATA operation in BIOS from Intel Smart Response to AHCI.
• Save changes in BIOS.
• Reboot the system.
• Go back into Bios (F2) and change SATA operation from AHCI to Intel Smart Response.
• Save the changes.
• Restart the system.
• Now system should boot into the normal mode.
• Please restart the system multiple times to check for issue resolution.

Please let me know if this helps.

Thank you for the welcome.

The computer is able to turn on after performing the first steps, but I am unable to get to the BIOS. I do not see the Dell logo when I turn the computer on. Instead all I see is a blank screen (the screen seems to be working as it is backlit). Pressing F2 on this screen does not seem to do anything.
