ASUS Certified Repair & Maintenance 3 — Questions and Answers
Question 1: An ASUS laptop powers on but the screen remains black. Which component should be tested first?
- The SSD
- The RAM modules by reseating or testing one at a time (Correct answer)
- The Wi-Fi card
- The USB ports
Correct answer: The RAM modules by reseating or testing one at a time
RAM issues are a common cause of a black screen on power-on; reseating or testing RAM sticks individually isolates faulty modules.
Question 2: What is the purpose of ASUS's 'Battery Health Charging' feature?
- To fast-charge the battery in 30 minutes
- To limit maximum charge to 80% to prolong battery longevity (Correct answer)
- To discharge the battery fully before each charge cycle
- To enable wireless charging
Correct answer: To limit maximum charge to 80% to prolong battery longevity
Battery Health Charging limits the maximum charge level to 80% (or 60%) to reduce electrochemical stress and extend battery lifespan.
Question 3: During an ASUS motherboard replacement, why is it critical to discharge static electricity before handling the board?
- To speed up the installation process
- To prevent electrostatic discharge (ESD) damage to sensitive components (Correct answer)
- To reset the BIOS settings
- To activate the warranty void sticker
Correct answer: To prevent electrostatic discharge (ESD) damage to sensitive components
ESD can instantly damage or degrade integrated circuits on the motherboard; using an anti-static wrist strap and mat is mandatory.
Question 4: What should a technician check if an ASUS laptop's touchpad is unresponsive after a keyboard replacement?
- The display brightness setting
- The touchpad ribbon cable connection under the keyboard (Correct answer)
- The Wi-Fi antenna cables
- The GPU thermal paste
Correct answer: The touchpad ribbon cable connection under the keyboard
The touchpad ribbon cable often routes under or alongside the keyboard and can be accidentally disconnected during keyboard removal.
Question 5: Which ASUS BIOS setting must be disabled to allow booting from a USB drive for OS reinstallation?
- Intel Hyper-Threading
- Secure Boot (Correct answer)
- XMP/DOCP memory profile
- CPU Virtualization (VT-x)
Correct answer: Secure Boot
Secure Boot blocks unsigned bootloaders; disabling it in ASUS BIOS/UEFI allows the system to boot from USB installation media.
Question 6: What type of thermal compound should be used when replacing the CPU cooler on an ASUS desktop motherboard?
- Electrical conductive silver epoxy
- Non-conductive thermal paste appropriate for the TDP rating (Correct answer)
- Standard white glue
- Thermal tape only
Correct answer: Non-conductive thermal paste appropriate for the TDP rating
Non-conductive thermal paste rated for the CPU's TDP ensures efficient heat transfer without risk of shorting nearby components if it spreads.
Question 7: An ASUS ROG desktop PC emits 3 long beeps during POST. What does this typically indicate?
- Successful POST completion
- RAM failure or no RAM detected (Correct answer)
- GPU initialization error
- Hard drive not found
Correct answer: RAM failure or no RAM detected
On ASUS AMI BIOS systems, 3 long beeps during POST typically signal a RAM error or no memory detected in the system.
