Mini PCI/PCI-E 2-Digit Laptop Motherboard Diagnostic Card

Mini PCI / PCI-E 2-Digit Laptop Motherboard Diagnostic Card

Keep your laptop running at its best with this professional-grade Mini PCI / PCI-E 2-Digit Diagnostic Card by OULLX. Designed specifically for laptop motherboard analysis, this compact debug tool displays POST (Power-On Self-Test) codes on its 2-digit LED readout, helping technicians and advanced users quickly identify and interpret motherboard status codes — saving time and guesswork during laptop servicing and troubleshooting.

⚠️ Important Compatibility Notice: This diagnostic card is designed for laptops only. It is not compatible with desktop computers, nor can it be used with a converter card to connect to a desktop. While compatible with most laptops, not all laptop motherboards are supported — this is a normal limitation of the tool, not a product defect. If your motherboard is not supported, please test with a different laptop. Made in Mainland China.

Key Features

• Dual-Interface Support: Compatible with Mini PCI, Mini PCI-E, and LPC Bus interfaces — only one interface needs to be connected at a time.
• 2-Digit LED Display: Clearly shows POST diagnostic codes for fast motherboard status interpretation.
• Stable Power Design: Equipped with 2 capacitors for stable power delivery and a red power indicator light for easy monitoring.
• Mini PCI-E Pin Support: Works with PIN-8, PIN-10, PIN-12, PIN-14, PIN-16, PIN-17, and PIN-19 for the Mini PCI-E port.
• LPC Bus Ready: Supports LPC interface with clearly defined pin layout (PIN1–LFRAME#, PIN2–LAD3, PIN3–LAD2, PIN4–LAD1, PIN5–LAD0, PIN6–GND, PIN7–LRESET#, PIN8–LCLK, PIN9–3.3V).
• Broad Laptop Compatibility: Supports popular platforms including IBM ThinkPad X60, T6, R6 series, and chips such as PC97551, PC87541, PC87591, H8S/2149, W83L950D, and TCPA.

Frequently Asked Questions

Q: Can I use this Mini PCI/PCI-E diagnostic card with a desktop computer?

A: No — this diagnostic card is designed exclusively for laptops. It inserts directly into a laptop's Mini PCI, Mini PCI-E, or LPC Bus port. It cannot be used with desktop computers, even with a converter card. If you need a diagnostic card for a desktop, please look for a full-size PCI/PCI-E POST card instead.

Q: Do I need to connect all three interfaces (Mini PCI, Mini PCI-E, and LPC) at the same time?

A: No. You only need to connect one interface at a time — whichever port is available on your laptop's motherboard. The other two interfaces can remain unconnected. The card will function correctly through a single connected port.

Q: How do I read the diagnostic codes on the 2-digit LED display?

A: When the card is powered and connected, the 2-digit LED display will show hexadecimal POST codes as the laptop's motherboard goes through its initialization sequence. You can cross-reference these codes with a standard POST code reference chart to identify the motherboard status or pinpoint where the initialization process stops, helping you diagnose the issue efficiently.

Q: My laptop is not displaying any codes — is the card defective?

A: Not necessarily. Some laptop motherboards are not compatible with this diagnostic card. This is a known limitation and is not a product quality issue. We recommend testing the card in a different laptop to confirm functionality. Every unit is tested before shipment to ensure it works correctly.
