Laptop motherboard tester - 3 interfaces: Mini PCI / Mini PCI EXPRESS / LPC

For PORTABLE PC ONLY. Mini PCI or Mini PCI Express port interface or LPC connection. This device should only be used by experienced users.

Details:

This test card supports 3 interfaces: mini-PCI port, mini-PCI Express port, and LPC. Only one interface is required, so you can use any one of the three, leaving the other 2 free. This tester is easy to set up and very stable.

STRUCTURE AND USE OF THE CARD
1-Mini PCI interface (connection to mini PCI port).
It's naturally shorter than your PC's mini PCI port

2-Mini PCIE interface (connection to mini PCI Express port).
New standard found on recent laptops. The card doesn't use all the pins on this port, but only 8/10/12/14/16/17/19. Note that in the Mini PCIE standard specifications, these pins are reserved and are generally used as LPC ports. This is the case with IBM, Toshiba, HP, Asus etc... Some marginal manufacturers do not respect these reserved ports, so the card cannot operate in mini PCIE.

3-LPC interface (connection to LPC-type briches)
For users without a mini PCI or Mini PCIE port, this interface will be salutary, as it exists on all notebooks. However, it rarely features a dedicated connector, so you'll have to use wires to connect the tester to it. From left to right, the pins correspond to:
PIN1 3.3V / PIN2 FRAME# / PIN3 LAD3 / PIN4 LAD2 / PIN5 LAD1 / PIN6 LAD0 / PIN7 GND / PIN8 LRESET / PIN9 CLK / PIN10 -3.3V

4-Chipset (ASIC)

5-Display LED (2 digits 7 segments), gives error codes and RST/CLK signals

6-Test port: used for board maintenance, do not use these pins

USING THE DISPLAY:

The display consists of 2 7-segment digits, together with 2 dots, indicating "RST" (left) and "CLK" (right) status. The two digits allow you to access the post's error code to locate the malfunction.
