[Your Name] Date: [Current Date] Subject: Firmware Reverse Engineering / Hardware Modification 1. Abstract Lenovo, like many OEMs, implements a BIOS-level whitelist in many of its consumer laptops, including the Lenovo G570. This whitelist restricts the system from booting if an unauthorized (non-Lenovo certified) PCIe or mini-PCIe device—such as a Wi-Fi card, WWAN card, or SSD adapter—is installed. This paper analyzes the technical basis of this restriction, outlines the risks involved, and provides a step-by-step methodology to remove the whitelist by modifying the system’s SPI flash BIOS image. The procedure described is for educational and advanced repair purposes only. 2. Introduction The Lenovo G570 is a legacy Sandy Bridge platform laptop (circa 2011) valued by enthusiasts for its durability and upgradeability. However, its BIOS (InsydeH2O) contains a hardware whitelist (often via an ACPI or PCIe vendor/device ID check ). Installing a third-party Wi-Fi 6 card or a different Bluetooth module triggers Error 104: “Unauthorized wireless card is plugged in. Power off and remove it.” lenovo g570 bios whitelist removal

Zac's Challenges:

Zac’s tech business is growing rapidly. He’s gone from being a developer with a good idea to now overseeing an ever-expanding team. Zac knows that in order for the business to grow successfully, it needs to stay true to its founding values and his staff need to feel valued and engaged. Zac wants to understand if he and his team are on the same page and he needs to do it quickly and cost effectively.

Zac's PCS Solution

Zac decides to use PCS Lite to get a quick temperature check of how his team are performing and what they think about the business. The PCS Lite report quickly surfaces the fact that his team have lost sight of the organisation’s purpose and goals. Zac realises that he needs to improve his on-boarding processes and help orientate the new team members better in the company culture and vision. 6 months later, Zac uses PCS Lite to check his new onboarding process is working; concludes that the growing team are much better aligned to his vision and are generally operating in a more positive working environment.
