Power Up Basics (Dell XPS 2023)
The model specifically detailed here is the Dell XPS 2013 model P91F004. It is a 15.6" XPS 15 9530 released in 2023. The models I typically work on include the RTX 4070 GPU upgrade.
This power up guide will be more aimed towards repairs and expected power up voltages and currents rather than the obvious of just pressing the power button to turn the laptop on.
When powering up the laptop for diagnostics, make sure to keep the heat sinks attached, and fans.
The simplest way to get the laptop to power on is remove the battery, and insert a USB-C power device in the right-hand USB-C port.
This will cause the laptop to auto-boot. The boot-up sequence should be:
- Insert USB-C. 20V should be negotiated.
- A current draw of 0.09A to 0.12A should be there for 4 seconds
- DELL logo should appear on screen.
- Current should go in sequence approximately 1.8A > 2A > 2.2A > 1.8A > 2.1A over the course of 18 seconds.
- After this the current should jump up and down between 1.9A to 5.8A and the screen should show Secured by Dell SafeBIOS. The laptop may boot into the BIOS (dropping to 0.1A as it reboots) or it may boot into Windows depending on configuration.
- Once in Windows the power usually floats up and down between 0.3A and 5.8A all depending on what's happening.
- Usually at Windows desktop idling it is under 0.5A with random short spikes of a few amps as things happen in the background.
If your motherboard has a fault on the RTX 4070 (or doesn't have a dedicated GPU installed and is using integrated graphics) the power draw would be around 0.3A less in most areas so:
- Insert USB-C. 20V should be negotiated.
- A current draw of 0.09A to 0.12A should be there for 4 seconds
- DELL logo should appear on screen.
- Current should go in sequence approximately 1.5A > 1.6A > 1.9A > 1.6A > 1.8A over the course of 18 seconds.
- After this the current should jump up and down between 1.6A to 4A and the screen should show Secured by Dell SafeBIOS. The laptop may boot into the BIOS (dropping to 0.1A as it reboots) or it may boot into Windows depending on configuration.
- Once in Windows the power usually floats up and down between 0.3A and 4A all depending on what's happening.
- Usually at Windows desktop idling it is under 0.5A with random short spikes of a few amps as things happen in the background.
