RE: Sudden black or blank screen on Inspiron 15 7559 Win 10
I'd suggest you run Dell F12 Preboot Diagnostics tool to check the hardware on computer. Please follow steps below:
1. Turn off computer and disconnect all peripherals - printer, flash drive, external drive, etc....).
2. Power on system, quickly start tapping the F12 key continuously. In boot menu, stroll down to diagnostic and then click on it. After quick tests, click on hard drive and run Thorough Test mode. Report back any error code. Please click on link below:
