ASUS (ASUSTeK Computer Inc.) is a multinational technology company headquartered in Taipei, Taiwan. It is one of the world’s largest manufacturers of computers, laptops, motherboards, graphics cards, and other electronics. ASUS is known for its gaming hardware under the ROG (Republic of Gamers) brand.

Main article: ASUS charges for previously free service

In May 2023, ASUS removed a tool they provided for unlocking the bootloader of their Zenfone and Republic of Gamers (ROG) smartphones. This tool was mentioned in advertising to appeal to tech-savvy customers and was provided free-of-charge. By early 2024, ASUS was charging approximately €185 for this same service.

Main article: Asus voids warranty of devices sent for repair over minor damages and performs unrelated repairs

ASUS customers reported that the company was rejecting their repairs under warranty due to alleged "Customer Induced Damage". An investigation by Gamers Nexus revealed that ASUS's repair process would void the warranty of products and charge for unrelated repairs, despite the customer only mentioning issues that are covered under warranty. A dispute had to be made for ASUS to finally agree to perform the repairs under warranty.

Asus sells replacement parts on their website, which (In my experience) was cheaper and less hassle than the warranty.

Between 2021 and 2026, flagship ASUS ROG laptops (including Strix, Scar, and Zephyrus lines) shipped with firmware that violated fundamental hardware programming standards, rendering devices unstable for real-time tasks. Independent forensic analysis revealed that ASUS engineers had placed blocking `Sleep()` commands (specifically `Sleep(0x64)`) inside high-priority Interrupt Service Routines (ISRs).^[1][2] This practice, which is strictly forbidden in kernel-level programming, caused the CPU to hang for over 100 milliseconds at a time, resulting in rhythmic system stutters and audio failure.^[3]

Additionally, investigations in 2025 revealed a "broken by design" violation of the PCI-SIG specifications regarding Power Management. The firmware hardcoded a mismatch in Latency Tolerance Reporting (LTR) values between the CPU Root Port (765µs) and the NVIDIA GPU Endpoint (0ns).^[4] This synchronization failure caused "Blue Screen of Death" (WHEA 0x124) crashes and black screens on high-end models.^[5]

Despite user reports spanning four years, ASUS support routinely misdiagnosed these firmware defects as software or driver conflicts, instructing users to perform ineffective Windows reinstallations or RMAs for hardware that was defective by design. While the ACPI stutter was patched in late 2025 following media outcry,^[6][7] the PCIe stability violations persist in 2026 model generations.

On the 8th of April 2026, ASUS has activated a new Privacy Notice to all users of ASUS Routers. The statement is as follows:
