Step 1: Checking the Power Source

1. Verify the Outlet: Ensure that the wall outlet is working by testing it with another working device, such as monitor, lamp, and so on.
2. Check the Power Strip: When using a power strip or surge protector, make sure it’s turned on and working properly. If possible, bypass the power strip to check if the power strip is faulty.

Step 2: Inspecting the AC Adapter and Cable

1. Visual Inspection: Look for any physical damage or fraying on the power adapter, cable, or the power port on the laptop. If you notice any damage, stop using the device immediately and contact Help Desk.
2. Connection Check: Ensure the adapter or charger is securely connected to the laptop and the power source.
3. Use a Different Adapter: Always use Dell provided or Dell-approved adapter or charger with your laptop. If available, test with a known working adapter to check if the adapter is faulty.

Step 3: Resetting the Real-Time Clock (RTC)

Real-time clock (RTC) reset restores the BIOS to factory default settings and resets the date and time. The reset process may restart the laptop several times depending on how it is configured.

Note: Real-time clock (RTC) reset is only available on some Alienware, Inspiron, Latitude, Precision, Vostro, and XPS laptops.

1. Unplug the Device: Disconnect all external devices.
2. Connect AC Adapter: Plug in the ac adapter or charger to the laptop.
3. Hold the Power Button: Press and hold the power button for 30-35 seconds, until the power LED blinks three times to discharge residual power.
4. Release Power Button: Release the power button to complete the real-time clock reset.
   Note: If the power is interrupted or the power button is held for less than 25 seconds or longer than 40 seconds, the reset process is aborted. Attempt to reset the RTC again.
5. Reconnect and Test: Plug the adapter back in and try to power on the laptop.

If the above steps didn't resolve the power issue on your laptop or you suspect hardware failure or damage, Contact Help Desk.

Troubleshooting a Dell Desktop That Does Not Turn On

Follow this troubleshooting sequence outlined below to systematically address power issues with your desktop.

Step 1: Inspecting the Power Button and Cables
