Garbled characters on output pages may indicate a printing problem related to which component?

Printer driver

Which 4 actions may help when troubleshooting a non-responsive touchscreen on a mobile device?

Reseating the device's battery Erasing all content/settings and restoring the device to factory defaults (factory reset/hard reset) Pressing a specific key combination/button to perform system restart (soft reset) Removing screen protector and cleaning the screen

Once the theory of probable cause of the problem has been established, the next troubleshooting step should be:

Testing the theory to determine the problem cause

T or F? Disk Defragmenter is a software tool used to rearrange data on magnetic drives in order to improve system performance. Defragmentation results in faster read/write operations of a magnetic hard drive's read/write heads because defragmentation consolidates data into the smallest contiguous regions. This means that the heads can access data sequentially without seeking data fragments in different areas of a disk

True

T or F? The Blue Screen of Death (BSoD) in MS Windows provides technical information that might help advanced users to determine the cause of stop error. Information typically displayed on the screen for this type of error includes: an error code, the memory address where it occurred, and the name of the driver that caused it.

True

T or F? The final step of a troubleshooting process should involve documenting findings, actions and outcomes. This step comes after verification of full system functionality and the implementation of applicable preventive measures.

True

T or F? When PC components are not getting enough power, common fixes include disconnecting all extraneous peripheral devices that might be putting too much load on the Power Supply Unit (PSU), reseating the PSU cable connectors inside the computer case, and using a PSU tester to check if the power supply is working properly.

True

What would help ensure proper re-assembly of a serviced mobile device? (4 answers)

Using appropriate hand tools Documenting and labeling cable and screw locations Magnetic mat/separate containers used for holding disassembled parts Manufacturer documentation used as a reference

According to troubleshooting theory, when should verification of full system functionality and implementation of applicable preventative measures be performed?

After implementing the solution

A dim display on a laptop LCD screen might indicate that there is a problem with: (2 answers)

Backlight Inverter

An IPv4 address within the range of 169.254.0.1 through 169.254.255.254 indicates a problem with what type of service?

DHCP

In laser printing, long vertical streaks on each output page indicate a problem with:

Damage to the imaging drum

An actuator arm assembly failure manifested by loud clicking noise emitted from the inside of the computer case is a problem symptom that should prompt for:

Data backup and hard driver replacement

T or F? Establishing a theory about the probable cause of a problem is a troubleshooting step that requires conducting research based on symptoms and may also involve asking for assistance from a more experienced tech.

False

T or F? The term "Stuck pixel" refers to a tiny spot on an LCD monitor display screen that permanently remains black when it should be activated and displaying color.

False

In laser printing, toner falling off of a printed copy indicates a problem with which component?

Fuser assembly

What might be caused by excessive dust buildup inside a computer case?

Overheating unexpected shutdowns intermittent device failures continuous reboots

Which actions should be the first step in a troubleshooting process?

Identifying the problem

After developing a plan of action to resolve a problem, the next step in a troubleshooting methodology should be to:

Implement the solution

The most common and simplest reasons that a computer monitor is unable to display a screen image include: (2 answers)

Loose cable connections wrong input selection

Which 2 actions might solve the problem of leaking/burst/bulged capacitors inside a computer case?

Motherboard replacement Capacitor replacement
