[NAME] Try turning off Fast Startup. Go to All settings / Power & sleep / click on the 'Additional power settings' link / click on 'Choose what the power buttons do' / click on  'Change settings that are currently unavailable' (if necessary) / then uncheck 'Turn on fast startup' under 'Shutdown settings'.
Hi all,  I'm hoping you can help a non-techie.  My XPS One 2720 won't get past the black Dell screen at start up - the whirling 5 dots don't appear.  If I press and hold the power button to turn off and then try again, it works (the whirling 5 dots appear and shortly after, everything loads up) it then turns back on again.  But I have to go through this same dance every time.  I've run the 40 min diagnostics on Dell.com/Support and that recommended updating 4 drivers, which I did.  But the problem still persists.    I'd really appreciate any help in pointing me in the right direction. Thanks,   
XPS One 2720, start up issue
