Thunderbolt over Type-C
Thunderbolt is a hardware interface that combines data, video, audio, and power in a single connection. Thunderbolt combines PCI Express
(PCIe) and DisplayPort (DP) into one serial signal, and additionally provides DC power, all in one cable. Thunderbolt 1 and Thunderbolt 2 use
the same connector as miniDP (DisplayPort) to connect to peripherals, while Thunderbolt 3 uses a USB Type-C connector.
Figure 7. Thunderbolt 1 and Thunderbolt 3
1 Thunderbolt 1 and Thunderbolt 2 (using a miniDP connector)
2 Thunderbolt 3 (using a USB Type-C connector)
Thunderbolt 3 over Type-C
Thunderbolt 3 brings Thunderbolt to USB Type-C at speeds up to 40 Gbps, creating one compact port that does it all - delivering the
fastest, most versatile connection to any dock, display or data device like an external hard drive. Thunderbolt 3 uses a USB Type-C
connector/port to connect to supported peripherals.
1 Thunderbolt 3 uses USB Type-C connector and cables - It is compact and reversible
2 Thunderbolt 3 supports speed up to 40 Gbps
3 DisplayPort 1.2 – compatible with existing DisplayPort monitors, devices and cables
4 USB Power Delivery - Up to 130W on supported computers
Key Features of Thunderbolt 3 over USB Type-C

Enhanced Pre-boot System Assessment (ePSA)
The ePSA is a diagnostic utility available on the tablet. This utility includes a series of tests for a tablet's hardware. Customers can run these
tests even if the computer lacks any media (hard drive, CD drive, etc.). If an ePSA-tested component fails, the system displays an error
code and generates a beep code.
Features:
• Graphical User Interface.
• Automatic Default Operation- runs test on all devices, allowing a user to interrupt and select any device.
• Checks the Master Boot Record for readiness to boot into a full OS environment.
• Tablet panel test.
• Video card.
• Battery test.
• Charger test.
• Primary battery.
• Multiprocessor cache test.
Running the ePSA Diagnostic Utility
NOTE: The following steps can be used to run the ePSA diagnostic utility in DOS mode without using an external keyboard.
1 Power on the system.
2 Before the Dell Logo is displayed, immediately press the Volume Up button to get the Boot Menu.
3 Scroll down the Diagnostics and then press the Volume Down button to select.
4 The tablet will begin running the ePSA utility.
Dell wireless charging mat
• Ensure that the correct AC adapter is plugged into the charging mat and AC input is connected and supplied to the adapter.
• Ensure that the charging mat is not placed directly on metal table or if using a metal table ensure there is at least a 5-cm gap between
the metal table and the charging mat.
• Place a known working wireless charging keyboard on the charging mat and check to see if the LED lights up. The keyboard must be
placed within the charging area and no object should be inserted between the keyboard/Mat and/or Mat/table.
• Or if using a tablet connected to the wireless charging keyboard, then check that the battery indicator displays charging.
• If all the above troubleshooting steps fail, then the charging mat may have malfunctioned. Please contact Dell Support for assistance.

Tablet LED
This section details the diagnostic features of the battery LED in a tablet.
Diagnostic LED
Tablets rely on the Battery LED light blinking amber/white pattern to determine failures listed in the following table:
NOTE:
• The blinking patterns will consist of 2 sets of numbers being represented by (First Group: Amber blinks, Second Group: White
blinks)
• First Group: The LED blinks 1 to 9 times followed by a brief pause with LED o at the interval of 1.5 seconds. (This is in Amber
color)
• Second Group: The LED blinks 1 to 9 times, followed by a longer pause before the next cycle starts again at the interval of 1.5
seconds. (This is in White color)
•Example: No Memory detected (2,3), Battery LED blinks two times of amber color followed by a pause, and then blinks three times
of white color. The Battery LED will pause for 3 seconds before the next cycle repeat itself again
The following table depicts the amber and white blinking patterns with possible troubleshooting resolution:
Table 1. LED pattern
Blinking pattern Problem Description Suggested Resolution
2,1 processor processor failure
2,2 system board, BIOS ROM system board, covers BIOS corruption or ROM error
