[29] In January 2013, ASUS officially ended production of its Eee PC series due to declining sales caused by consumers increasingly switching to tablets and Ultrabooks.

[36] As of 2009[update], ASUS had manufacturing facilities in Taiwan (Taipei, Luzhu, Nangang, Guishan), China (Suzhou, Chongqing), Mexico (Ciudad Juárez) and the Czech Republic (Ostrava).

[46] In 2013, ASUS revealed an Android-based tablet computer that, when attached to a keyboard, becomes a Windows 8 device, which it called the Transformer Book Trio.

Equipped with the high-performance Intel's Core i9 processor and Nvidia's GeForce RTX 3050 Ti graphic performance, making the biggest innovation breakthroughs in tablet markets.

The Xonar DX was able to emulate the EAX 5.0 effects through the ASUS GX software while also supporting Open AL and DTS-connect.

[62] ASUS then released the Xonar HDAV 1.3, which was the first solution enabling loss-less HD audio bit streaming to AV receivers.

[63] In May 2009, ASUS launched the Essence ST sound card, targeted at high-end audiophiles, and featuring 124 dB SNR rating and precision audio clock tuning.

[79] In January 2021, ROG announced the establishment of a new esports academy in India, with plans to scout and train professional gamers for the Counter-Strike: Global Offensive (CS:GO) PC game.

[80] The initiative will provide shortlisted gamers with coaching, gaming equipment, and stipends to prepare them for competitive esports tournaments on both the national and international levels.

"[83] In 2006, ASUS obtained IECQ (IEC Quality Assessment System for Electronic Components) and HSPM (Hazardous Substance Process Management) certification for its headquarters and all of its manufacturing sites.

In the following month, it received EU Flower certification for the same N-Series notebooks at an award ceremony held in Prague.

[85] In December 2008, Det Norske Veritas conferred the world's first EuP (Energy-using Product) certification for portable notebooks on these machines.

[85] In April 2008, ASUS launched its "PC Recycling for a Brighter Future"[87][88] program in collaboration with Intel and with Tsann Kuen Enterprise Co.

The program collected more than 1,200 desktop computers, notebooks and CRT/LCD monitors, refurbished them and donated them to 122 elementary and junior high schools, five aboriginal communities and the Tzu Chi Stem Cell Center.

In September 2008, PC Pro discovered through a reader that ASUS had accidentally shipped laptops that contained cracked and unlicensed software.

At the time, an ASUS spokesperson promised an investigation at "quite a high level", but declined to comment on how the files got on the machines and recovery media.

In February 2014, a security vulnerability in the AiCloud functions on a number of ASUS routers was compromised to distribute a text file warning of a vulnerability, disclosed in June 2013, allowing the ability to "traverse to any external storage plugged in through the USB ports on the back of the router" via the open internet.

[93] The U.S. Federal Trade Commission issued a complaint about the breach for the company's "failure to employ reasonable security practices has subjected consumers to substantial injury", alleging that ASUS had also failed to perform basic penetration tests, allowed users to maintain a default admin password for the AiDisk feature and failed to notify users of security updates in a timely fashion.

In March 2019, Kaspersky Lab researchers disclosed a supply chain attack that affected the ASUS Live Update software bundled on its laptops, dubbed ShadowHammer.

It deployed a further payload if the device's network adapter matched an entry on an internal target list of around 600 MAC addresses.

Kaspersky and Symantec estimated that between 500,000 and 1 million devices were infected with the backdoor, although ASUS attempted to downplay the severity of the breach by noting the extremely targeted nature of the attack.

In April 2019, ESET disclosed that a group known as BlackTech had performed targeted attacks with malware known as Plead, distributed via the updater for the ASUS WebStorage service.

ESET stated that the group was likely using a man-in-the-middle attack via a vulnerability in routers, in combination with the updater using an unencrypted HTTP connection.

In mid-March, the company did announce it was halting its operations in Russia, following a social media boycott and government pressure.

[100][101] In April 2023, a post on the PCMasterRace subreddit began gaining popularity regarding the user's AMD Ryzen 7 7800X3D CPU, which had visible burning, along with the socket of the ASUS motherboard.

[102] This sparked the attention of both people interested in PCs, who initially thought it was an issue with the 3D V-Cache Technology (as there had been previous user reports similar to this incident),[102] as well as enthusiast YouTube channels such as Gamers Nexus, who ran tests to successfully recreate the burning of their CPU.

[103][104][105] Later that month, ASUS responded to the public backlash by reversing course, releasing a statement informing users that they will continue to honor warranty on motherboards that have been updated to beta BIOS versions, as well as extend motherboard warranty coverage to uses of AMD EXPO, Intel XMP, and DOCP memory overclocking technologies.

[108] Several days later, ASUS honoured the warranty and performed the repair of the original issue under pressure from Gamers Nexus,[108] as well as subsequently apologised for the poor service.
