Fix: Dell laptop Inspiron 15 slow on dell logo or stuck.

 My dell Ispiron 15 5510 having and slow booting time. When I  power up my laptop it takes 5 minutes on dell logo but when it is on windows it became fast. This is what I do to fix this problem.

Solution. Turn off the Fast startup on power setting.

1. On your windows 10 go to Setting>System>Power and sleep>additional power settings.
2. On the left menu list click the "Choose what the power buttons do".
3. Click the link "Change setting that are currently unavailable"
4. Uncheck the "Turn on the fast startup".
