Confirm the physical setup of your computer to ensure it is not affecting how your computer is operating:

• Check all the cabling going to and from your computer. Is it firmly seated in place?
• Check that all powered devices have power.
• Check that no media is in any reader through the computer booting.
• Check that another device or object is not crushing or activating an input device.
• Check that no damage has occurred, or liquid has been spilt on the computer or its devices.

Methods to wake from Sleep

You could resume from sleep by using any input device. This can be tapping any key on the keyboard, clicking or moving a mouse, power button. (Alternatively, if Wake-on-LAN is set, a timer has been scheduled or touching the touchpad, opening the lid, or pressing the sleep button.)

What is Hybrid Sleep?

Hybrid sleep - a combination of sleep and hibernate. It puts any open documents and programs in memory and on your hard disk and then puts your computer into a low-power state. So that you can quickly resume your work. If a power failure occurs, Windows can restore your work from your hard disk drive. This can be useful for desktop computers, but not as much for a laptop. This option is the default setting for desktop computers. It is the opposite for laptops, which ship with it disabled. (Desktops depend on mains power, while laptops have onboard batteries to mitigate power issues.)

You can two-way swap the hard drive.

The quickest and easiest way to rule out the operating system is to two-way swap the Boot hard drive. Use a boot hard drive from a working example of the same computer model.

• If the fault stays with the computer, you have ruled the operating system out, and I would recommend contacting Dell Technical Support for further aid.
• If the fault follows the hard drive, it is likely an issue with the operating system and moves on to the next set of steps.
• If there is no suitable computer to swap parts with, then move on to the next set of steps.

Reinstall the operating system to how it shipped from Dell.
