Re: my dell latitude e6420 screen goes blank when it has to boot

hello DELL-MANSHU 

am very grateful for the response. i tried what u said...at the logo boot...it showed "entering diagnostics" but right after the Dell logo screen goes, the screen stays blank forever.

only places the screen displays is there Dell logo and only if i choose to enter BOIS setting..

i also release the single USB port on the left side and the e-SATA port  do not respond when i placed a bootable usb drive in them to try to run windows. the other 2 usb ports by the e-SATA port responded but when i choose to boot from the flash drive, screen goes blank and stays blank forever .please me!!!!!!!!!
