Recently my Dell Inspiron P57G was experiencing issues when entering sleep mode. When trying to wake the PC, a blank screen was coming on. After some research, I concluded it was due to bugs with the most recent version of the display driver. These were the steps I took to remediate the issue.
- Go to Dell Support page and find the Intel HD Graphics 510 515 520 530 540 Driver.
- Click 'Other Versions'
- Download the most recent driver prior to 08/13/2017.
- Follow the installation instructions and restart the PC.
- If prompted to overwrite newer drivers, select 'Yes'
After restart, either force the PC to sleep or let it sleep on its own. The problem should've been fixed.
