1.1 Given a scenario install and configure laptop hardware and components
Hard ware /device replacement
Consult the documentation from manufacturer
Some models need a t-8 torx screwdriver
Might be countersunk in deep holes
Always ensure you are grounded
Keyboard
Try not to damage the data cable connector to system board
Hard Drive
Back up the old drive before swap
SSD vs hybrid vs magnetic disk
Many devices still use a mag disk hard drive
Most are moving to solid state or hybrid
Solid states are not as susceptible to damage if dropped and are generally faster
CON: more expensive, don't display as many warning signs as other physical drives
Hybrids have a magnetic disk and some solid state memory. These monitor the data being read from the hard drive and cache the most frequently accessed bits in the high speed flash memory. Needs to be learned to see te improvement
1.8 in vs 2.5 in
The 2.5 in hard drives are small (laptop good) but in comparison to 3.5 in, they have less capacity and cache and they operate at a lower speed
2.5: 5400 to 7200 rpm/ 2.5 W power used
3.5: 7200 to 10000 rpm. /5 W power used
1.8 very small. Only used in subnotebooks and audio players
Memory
There should be a panel used for access to the memory modules. If not, refer to documentation
Smart Card Reader
Come in internal and external versions.
External probably plugs into USB, may need a driver
May use the express card slot
Internal readers will reside in a drive bay as a hard drive or optical drive.
To replace:
Optical Drive
Easier than hard drive or memory
Remove the screw that secures the drive to the bottom of the notebook.
Grab the edge of the bezel and slide the drive out of the base enclosure.
Insert the new one into the base until the connector is seated and replace the screw that secures the drive to the bottom of the notebook
Wireless card/ Bluetooth module
Both wifi and bluetooth wireless cards that are built in can be replaced if they go bad. Sometimes they reside near the memory, so you would open the same panel.
Other times, you have to dismantle memory, keyboard, optical drive and hand rest to get
Not always together, consult the docs
Once you've found the card, disconnect the two antenna contacts from the card.
DO NOT PULL BY WIRE
Pull by the connector itself.
Remove any screws from the wirelss card and gently pull out by the slot.
Insert the replacement at a 45 degree angle and reconnect the antenna to the adapter. Reverse
Cellular card
Changing an external broadband card is as simple as pulling the old usb stick out and plugging in the new one.
USB is plug and play: you shouldn't have to do anything further
Sometimes there is a CD or downloads
Changing an internal is very similar to a wifi adapter, follow above
Video card
Ensure that the new card was supported by the laptop and the OS
Mini PCIe
Since many of the wireless cards are mini-pcie, replacing any other card in this format will follow the same steps.
Documenation for location.
Screen
One of the harder ones
DC Jack
Replacing a bad dc jack usually requires soldering== if you can't, just replace the mobo
Remove all the parts to get to the mobo
In some cases, the old one can be used, the old solder just needs to be removed
If not, remove the old dc jack by unsoldering it from the connector. Then put the new jack in and solder it to the connectors.
Probably just replace the mobo
Battery
Remove the battery storage bay, remove batter, insert and replace the bay.
**WARNING** If bitlocker is enabled, the laptop will not boot after replacement unless the key is provided
Touchpad
Another complicated one
Plastic/ frames
May be hold in place by screws or snaps.
Never force a piece
Restoring the full case is important. Leaving open spaces can tamper with circulation, resulting in overheating
Speaker
Remove hard drive, battery pack and the screws holding the body together
System board
Remove everything prior to these notes.
CPU
If it is not built into the mobo, it can be replcaed. If it is integrated, then just replace mobo.
If upgrading and not just replacing, make sure BIOS supports the new one.
May need to flash the BIOS to support
Follow the above notes for removing the case, keyboard and display.
As always, follow documentation from manufacturer
1.2 Given a scenario, install components within the display of a laptop
Types
Laptop displays are
-LCD: have replaced CRTs as the default display type for laptops and desktops.
Two major types are used:
-active matrix screens:
Uses a separate transisitor for each individual pixel in the display, resulting in higher refresh rates and brighter display quality. Use ore power.
There is a variant called thin-film transistor TFT uses multiple transistors per pixel, improving quality further.
-passive matrix screens:
Row of transistors across the top of the screen and a column of them down the side. It sends pules to each pixel at the intersection of each row and column combination, telling it what to do.
Becoming obsolete because the're less bright and have poorer regresh rates and quality. PRO: they use less power
Main difference is quality, both use some kind of lighting behind the LCD panel to make the screen viewable. One or more small fluorescent tubes are used to backlight.
TN vs IPS
Two majorkinds of LCDs
Twisted Nematic (TN): twisted nematic is older of the two for flat panel displays.
In-Plane Switching (IPS):
Fluorescent vs LED backlighting
LCDs can use two kinds of backlighting:
Characteristic
Flurorescent
LED
Size
Thicker and heavier
Thinner and lighter
Cost
Cheaper
More expensive
Power
High power consumption and heat generation
Lower power consumption and heat generation
Brightness
Lower
Higher
Lifespan
Shorter
Longer
LED
OLED
WiFi antenna connector/ placement
Located in display.
Wireless card in the body of laptop
Webcam
If replacing, will need to disconnect the laptop lid from the base. Remove the screw covers and screws holding the display bezel in place and remove the screen from the lid assembly.
Carefully remove the tape and remove camera
Attach the replacement cable to the new camera and reverse
Microphone
Many desktop systems lack a built-in microphone, almost all laptops have one.
Sometimes the microphone will be located on the laptop bottom
Sometimes it will be in the display next to the webcam or off to the side.
If needed to replace, follow the same steps on the webcam
When you unhook lid from bottom, unplug cables from the board and one of those will be the microphone cable.
Sometimes the cable can be cut by the constant opening and closing of the case
Inverter
Component that takes DC power and converts it to an AC form that can be used by the LCD screen
Implemented as a circuit board that is located behind the LCD
Problems with flickering display or dimness occur, the inverter is probably the problem
If the inverter needs to be replaced you should be aware that it may contain stored energy so it may need to be discharged to be safe.
Digitizer/ touchscreen
Digitizers:
Exam essentials
Differentiate the types of displays available in laptops
Two major types of LCDs are used
Active matrix screens and passive matrix screens
Describe the location and operational characteristics of the wireless antenna in a laptop
Located in the display
Moving the laptop changes the polarity of the antenna
Identify the location and function of the inverter
An inverter is a component that takes DC power and converts it to a form that can be used by the LCD screen
Implemented as a circuit board behind the LCD
1.3 Given a scenario, use appropriate laptop features
Special function keys
Docking station
Docking stations or port replicators
Cheapest form of docking station is port replicator
