Mod 01 Taking a Computer Apart and Putting it Back Together
1. You replace an internal drive that is only used to backup data on a computer. Before you
install the case cover, you power on the computer and observe the disk drive lights are not
blinking. You suspect it may not be receiving power, but cannot find the power supply tester.
How can you quickly verify whether power is being supplied to the disk drive?
a. Use a POST card
b. Replace the power supply
c. Run diagnostic software once the OS loads
d. Use a multimeter
ANSWER: d
FEEDBACK: a. Incorrect. A POST (power-on self-test) card is used to
troubleshoot problems that occur after you power on the
computer but before the operating system is loaded. The
replacement drive is only used to backup data so we can
infer that it does not contain the operating system. The
question does not indicate the computer did not boot
successfully so POST must have completed without errors.
b. Incorrect. Replacing the power supply may fix the problem
but it is not the best way to quickly verify whether power is
being supplied to the drive.
c. Incorrect. Running diagnostic software once the operating
system is up and running will not determine if there is power
being applied to the drive. If no power is being supplied, the
system will simply will not detect the hard drive.
d. Correct. You can use a multimeter to verify the appropriate
voltage level is detected on the connector used to supply
power to the drive.

3. An employee informs the help desk the laptop they are using cannot update the login
credentials when they plug it in to the company's wired network. Wireless connectivity is fine,
but the login credentials cannot be updated using Wi-Fi. What is a possible action the help desk
could take to troubleshoot the problem?
a. Replace the network card
b. Ping the loopback address
c. Use a loopback plug
d. Use a USB to RJ-45 dongle
ANSWER: c
FEEDBACK: a. Incorrect. The network port on a laptop is integrated into the
motherboard so the help desk would not try to replace the
network card.
b. Incorrect. Ping is used to verify network connectivity.
However, pinging the loopback address (127.0.0.1) is used to
verify the networking protocols are installed and working
properly on the laptop. It does not transmit any data so it will
not serve as an effective method to test the network port on
the laptop.

7. The original P1 connector had 20 pins, why did the development of PCIe induce the adoption
of a 24-pin P1 connector?
a. PCIe slots are faster than the previous generation and requires more power
b. The four new PCIe slots each require one extra pin on the P1 connector
c. To provide an additional 12 volts to the PCIe slots required by graphics cards
d. ATX specification 1.1 supports PCIe and calls for additional power requirements
ANSWER: a
FEEDBACK: a. Correct. PCI Express (PCIe) slots are faster than PCI and
require additional power. The 24-pin or 20+4-pin P1
connector provide +12 volts, +5 volts, and +3.3 volts of
output.
b. Incorrect. Mother boards are not limited to four PCIe slots.
Some have less, some have more so the implied limitation is
not accurate.
c. Incorrect. The 24-pin P1 connector provides +12 volts, +5
volts, and +3.3 volts, not just 12 volts. In addition, PCIe slots
are not only for graphics cards. A variety of devices can be
installed in PCIe slots such as sound cards, wired and
wireless network cards, video capture cards, RAID controller
cards, etc.
d. Incorrect. ATX 1.1 does not support the additional power
requirements of PCIe and does not call for a 24-pin P1
connector; ATX 2.2 does.

8. Your company sells hundreds of large storage disk arrays every year that can be configured
locally using a dedicated laptop. You travel between many customer sites providing maintenance
and support to these laptops. It is your responsibility to ensure you have the necessary FRUs as
you travel from site to site. At the very least, what type of FRUs will you keep on-hand?
a. DIMMs, monitor, keyboard, mouse, and wireless card
b. Port replicator, webcam, headphones, network cable
c. P1 connectors, SATA cables, video card, and a multimeter
d. Memory modules, hard drives, keyboards, and wireless card
ANSWER: d
FEEDBACK: a. Incorrect. Laptops do not use DIMMs (dual inline memory
modules), they use SO-DIMMs (small outline DIMMs). The
keyboard and wireless card are FRUs (field replaceable
units).
b. Incorrect. None of these devices are considered FRUs (field
replaceable units). The webcam is not considered an FRU as
it is typically built into the screen and cannot be easily
replaced compared to a traditional FRU.
c. Incorrect. Laptops do not use P1 connectors. SSDs on a
laptop typically slide into a connector so you would not be
replacing SATA cables as you do in a desktop. The video
card is integrated into the motherboard and not considered
an FRU. A multimeter is not an internal FRU device.
d. Correct. FRUs are field replaceable units. These are internal
devices that can be replaced in the field with relative ease if
they become defective.

9. Maria has a laptop with a motherboard that is beyond repair. She comes to your computer
repair shop and requests that you replace the motherboard. What are two of the most likely
responses you will give her?
a. Buy a new laptop because replacing it will be more cost-effective than repairing it.
b. You thank them for their business, tell them how much it will cost, and how long it
will take.
c. You assure the customer it is not the system board because they seldom go bad; you
will troubleshoot and fix it.
d. Your shop has made a conscious decision not to replace motherboards on laptops.
e. It will take a long time because laptop motherboards are not typically in stock.
ANSWER: a, d
FEEDBACK: a. Correct. Replacing the motherboard on a laptop can be time-
consuming and costly so this is not a recommended course
of action.
b. Incorrect. Unless you are very experienced replacing
motherboards in laptops, you don't know for sure how much it
will cost and how long it will take. You might end up losing
money in the process and not complete the task to the
customer's satisfaction.
c. Incorrect. You cannot make an absolute determination on
what is or is not the problem without some level of
troubleshooting. It is better not to give the customer what
could be a false sense of hope.
d. Correct. Choosing not to replace motherboards on laptops is
a reasonable policy to adopt because it is time-consuming
and costly.
e. Incorrect. Not in stock where, in your shop, or at the factory?
In either case, the process is time-consuming and costly.
Thus, it is best not to replace motherboards in laptops.

7. The original P1 connector had 20 pins, why did the development of PCIe induce the adoption
of a 24-pin P1 connector?
a. PCIe slots are faster than the previous generation and requires more power
b. The four new PCIe slots each require one extra pin on the P1 connector
c. To provide an additional 12 volts to the PCIe slots required by graphics cards
d. ATX specification 1.1 supports PCIe and calls for additional power requirements
ANSWER: a
FEEDBACK: a. Correct. PCI Express (PCIe) slots are faster than PCI and
require additional power. The 24-pin or 20+4-pin P1
connector provide +12 volts, +5 volts, and +3.3 volts of
output.
b. Incorrect. Mother boards are not limited to four PCIe slots.
Some have less, some have more so the implied limitation is
not accurate.
c. Incorrect. The 24-pin P1 connector provides +12 volts, +5
volts, and +3.3 volts, not just 12 volts. In addition, PCIe slots
are not only for graphics cards. A variety of devices can be
installed in PCIe slots such as sound cards, wired and
wireless network cards, video capture cards, RAID controller
cards, etc.
d. Incorrect. ATX 1.1 does not support the additional power
requirements of PCIe and does not call for a 24-pin P1
connector; ATX 2.2 does.

8. Your company sells hundreds of large storage disk arrays every year that can be configured
locally using a dedicated laptop. You travel between many customer sites providing maintenance
and support to these laptops. It is your responsibility to ensure you have the necessary FRUs as
you travel from site to site. At the very least, what type of FRUs will you keep on-hand?
a. DIMMs, monitor, keyboard, mouse, and wireless card
b. Port replicator, webcam, headphones, network cable
c. P1 connectors, SATA cables, video card, and a multimeter
d. Memory modules, hard drives, keyboards, and wireless card
ANSWER: d
FEEDBACK: a. Incorrect. Laptops do not use DIMMs (dual inline memory
modules), they use SO-DIMMs (small outline DIMMs). The
keyboard and wireless card are FRUs (field replaceable
units).
b. Incorrect. None of these devices are considered FRUs (field
replaceable units). The webcam is not considered an FRU as
it is typically built into the screen and cannot be easily
replaced compared to a traditional FRU.
c. Incorrect. Laptops do not use P1 connectors. SSDs on a
laptop typically slide into a connector so you would not be
replacing SATA cables as you do in a desktop. The video
card is integrated into the motherboard and not considered
an FRU. A multimeter is not an internal FRU device.
d. Correct. FRUs are field replaceable units. These are internal
devices that can be replaced in the field with relative ease if
they become defective.

9. Maria has a laptop with a motherboard that is beyond repair. She comes to your computer
repair shop and requests that you replace the motherboard. What are two of the most likely
responses you will give her?
a. Buy a new laptop because replacing it will be more cost-effective than repairing it.
b. You thank them for their business, tell them how much it will cost, and how long it
will take.
c. You assure the customer it is not the system board because they seldom go bad; you
will troubleshoot and fix it.
d. Your shop has made a conscious decision not to replace motherboards on laptops.
e. It will take a long time because laptop motherboards are not typically in stock.
ANSWER: a, d
FEEDBACK: a. Correct. Replacing the motherboard on a laptop can be time-
consuming and costly so this is not a recommended course
of action.
b. Incorrect. Unless you are very experienced replacing
motherboards in laptops, you don't know for sure how much it
will cost and how long it will take. You might end up losing
money in the process and not complete the task to the
customer's satisfaction.
c. Incorrect. You cannot make an absolute determination on
what is or is not the problem without some level of
troubleshooting. It is better not to give the customer what
could be a false sense of hope.
d. Correct. Choosing not to replace motherboards on laptops is
a reasonable policy to adopt because it is time-consuming
and costly.
e. Incorrect. Not in stock where, in your shop, or at the factory?
In either case, the process is time-consuming and costly.
Thus, it is best not to replace motherboards in laptops.

b. The keyboard cable(s) will need to be disconnected from the ZIF socket(s).
c. The keyboard cable will need to be disconnected from the mini-PCIe slot.
d. The keyboard bezel will need to be removed.
e. The technician will need to remove the display assembly and system board.
ANSWER: b, d
FEEDBACK: a. Incorrect. The keyboard backlight component is integrated
into the laptop keyboard that illuminates the keys. The laptop
will be powered off when the keyboard is removed, making
this choice irrelevant.
b. Correct. Typical laptop keyboards are connected to the
system board via one or more ribbon cables. The system
board end of the ribbon cable utilizes ZIF (zero insertion
force) sockets. These cables will need to be disconnected
prior to removal of the keyboard.
