Laptop Components
- Chassis
- motherboard
- power supply
- display screen
- keyboard
- touchpad
AC Adapters
laptop needs a power supply to convert the AC supply from the power company to the DC voltages used by the laptop’s components. are normally universal (or auto-switching) and can operate from any 110–240 VAC 50/60 Hz supply, though do check the label to confirm.
battery
Laptop computers use removable, rechargeable Lithium ion (Li-ion) available in 6-, 9-, or 12-cell versions, with more cells providing for a longer charge.
a system or device has a smaller number of components that can be easily removed and replaced on-site by a technician without needing to send the entire unit for repair;
Fewer field-replaceable units (FRU)
is a smaller alternative to a DIMM, being roughly half the physical size of a regular DIMM, slot pops-up at a 45º angle to allow the chips to be inserted or removed.
small outline DIMM (SODIMM)
wireless cards
essentially enabling internet access without needing a physical cable connection; most modern laptops have a built-in wireless card,
is a small version of the ….. that’s used in portable devices and compact computers. I
Mini PCI Express (MiniPCIe)
Migration
means using backup software to create an image or clone of the old drive and store it on USB media.
Replacement
means that only data is backed up from the old drive. The new drive is then fitted to the laptop and an OS plus apps installed. User data can then be restored from backup.
Laptop HDDs
are usually 2.5″ form factor, though sometimes the 1.8″ form factor is used. tend to be slower
(usually 5400 rpm models) and lower capacity, reduced height units designed for ultraportable laptops, standard has a z-height of 9.5 mm; an ultraportable laptop might require a 7 mm (thin) or 5 mm (ultrathin) drive.
Keyboard and Touchpad replacement
- Read the documentation instructions
- Orginal fitting size
- When replacing an input device, use the OS/driver settings utility or app to configure it.
fingerprint reader board
Is a biometric sensor and is attached to the motherboard by a flat ribbon cable in the same way as the keyboard and touchpad. is configured in conjunction with an authenticator app, such as
Windows Hello.
near-field communication (NFC) scanner
NFC might be implemented as a feature of the keyboard, touchpad, or fingerprint reader. As well as the data connection to the motherboard, the NFC sensor must be connected to its antenna.
mSATA (mini-SATA)
is a type of solid-state drive (SSD) that is smaller than a standard SSD. It’s used in devices that are portable and have limited power, such as laptops, tablets, and netbooks.
M.2
is a form factor for solid-state drives (SSDs) that are small, rectangular, and designed to fit into a computer’s motherboard. M.2 drives are also known as Next Generation Form Factor (NGFF) drives.
Mini-PCIe (mPCIe)
is a small expansion card interface that’s used in laptops, mobile devices, and other compact systems. It’s a variation of the PCI Express (PCIe) interface, and is designed to save space while still providing a fast connection.
