Keyboard and Security Component Replacement

components such as the keyboard, touch pad, and biometric sensors can easily be damaged
- bc they are mechanical components
can be more cost-effective to replace damaged components than buy a new laptop

Keyboard and Touchpad Replacement

When you are replacing components such as the keyboard and touchpad
- almost always need to use the same part as was fitted originally
Each part connects to the motherboard via a data cable
- typically a flat ribbon type
- cable is held in place by a latch that must be released before trying to remove the cable and secured after insertion
When replacing an input device, use the OS/driver settings utility or app to configure it
- keyboard should be set to the correct input region

might be economical to lift a single key for cleaning or replacement
- pry off the plastic key cap with a flat blade to expose the retainer clip
- retainer clip can also be removed for cleaning
  - is fragile
- line up each component carefully and then push to snap it back into place

On a laptop, biometric sensors are typically implemented as a fingerprint scanner
- camera can also be used to make facial scans or to scan an iris eye patter
- fingerprint sensor might be installed as a separate component or might be a feature of the keyboard or touchpad
fingerprint reader board is attached to the motherboard by a flat ribbon cable in the same way as the keyboard and touchpad

near-field communication (NFC) scanner on a laptop is primarily used to pair peripheral devices or to establish a connection to a smartphone
might be implemented as a feature of the keyboard, touchpad, or fingerprint reader
NFC sensor must be connected to the motherboard and its antenna
