ASUS Risk Management & Mitigation 3 — Questions and Answers
Question 1: When working on an ASUS desktop with capacitors on the motherboard, which risk must technicians consider even after unplugging the power cable?
- RF interference from nearby devices
- Residual charge stored in capacitors can cause electric shock (Correct answer)
- Loss of BIOS settings
- Static buildup from the power cable
Correct answer: Residual charge stored in capacitors can cause electric shock
Capacitors can retain dangerous voltage charges for minutes after power removal, requiring discharge procedures before safe handling.
Question 2: A customer brings an ASUS ROG laptop claiming it was damaged during a previous repair. What is the BEST risk mitigation strategy before beginning a new repair?
- Immediately begin the repair to avoid delays
- Document pre-existing damage thoroughly with photos and notes before touching the device (Correct answer)
- Ask the customer to sign a blank liability waiver
- Refuse service to avoid further liability
Correct answer: Document pre-existing damage thoroughly with photos and notes before touching the device
Thorough pre-repair documentation with photos protects the technician and service center from false claims of technician-caused damage.
Question 3: Which cooling precaution is MOST important when replacing thermal paste on an ASUS CPU?
- Apply as much thermal paste as possible for maximum coverage
- Ensure paste does not contact surrounding circuitry to prevent short circuits (Correct answer)
- Use water-based thermal paste for better conductivity
- Skip paste application on integrated GPU to save time
Correct answer: Ensure paste does not contact surrounding circuitry to prevent short circuits
Excess conductive thermal paste contacting PCB traces or capacitors around the CPU socket can cause electrical shorts and permanent damage.
Question 4: What is the primary purpose of using a torque specification when reassembling ASUS laptop components with screws?
- To reduce repair time
- To prevent over-tightening that cracks PCBs or under-tightening that causes loose connections (Correct answer)
- To comply with recycling regulations
- To ensure screws are color-matched correctly
Correct answer: To prevent over-tightening that cracks PCBs or under-tightening that causes loose connections
Proper torque prevents PCB cracking from over-tightening and vibration-induced failure from under-tightening, both of which are quality risks.
Question 5: When servicing an ASUS all-in-one PC with an integrated PSU, which additional risk is present compared to a standard desktop?
- Higher chance of RAM incompatibility
- Mains voltage is present inside the display enclosure, requiring extra caution (Correct answer)
- Faster processor speeds create more heat
- Wi-Fi interference from the display panel
Correct answer: Mains voltage is present inside the display enclosure, requiring extra caution
AIO units route mains (AC) voltage internally to the integrated PSU behind the display, creating electrocution risk that external PSU desktops do not have.
Question 6: A customer's ASUS device fails its warranty claim due to liquid damage, but the customer denies liquid contact. What risk mitigation tool helps the technician support the finding?
- Running a benchmark test
- Pointing to the triggered liquid damage indicator (LDI) sticker inside the device (Correct answer)
- Checking the serial number label
- Reviewing the customer's purchase receipt
Correct answer: Pointing to the triggered liquid damage indicator (LDI) sticker inside the device
ASUS devices include LDI stickers that permanently change color upon liquid contact, providing objective evidence of moisture exposure.
Question 7: Which workspace condition MOST increases the risk of ESD damage to ASUS components during repair?
- A brightly lit workbench
- Low humidity environments below 30% relative humidity (Correct answer)
- Using a metal workbench
- Having multiple monitors at the workstation
Correct answer: Low humidity environments below 30% relative humidity
Low humidity allows static charges to accumulate more easily on surfaces and people, significantly increasing ESD risk to sensitive electronics.
