Notebooks Unit objective: Identify notebook components and features
Topic A Topic A: Notebook hardware components Topic B: Notebooks displays Topic C: Laptop features
Notebook computer Small size Light weight Standard client operation system Components modified from desktop Touchpad Keyboard Monitor
Typical notebook components CPU Memory Hard drive CD or DVD drive Monitor Keyboard Pointing device Network adapter Modem Peripheral ports One or more slots for expansion cards
Notebooks Not as easy to upgrade as desktops Little compatibility between manufacturers or within a manufacturer’s own lines Typically more expensive than desktops Designed to be small, lightweight, and portable
Netbooks Subcompact notebooks Smaller than regular notebooks Designed for wireless Internet use Lower processing power and storage capacity Easy to travel with Run variety of operating systems
Notebook batteries Vary in size and shape Provide 30 minutes to 8 hours of power
Power adapters External power cord and transformer Replacements must be model-specific 12-volt power adapters available Computer plug TransformerOutlet plug
Auto-switching Automatically switch between battery and AC power AC power supply connected, notebook runs on external power No AC power supply connected, notebook runs on battery –Runs on battery until fully discharged or connected to AC power supply OS monitors battery power and displays low-battery warnings
Notebook processors Engineered to: –Use less power –Generate less heat For up-to-date specs refer to manufacturers’ Web sites: –http://www.amd.com/us/products/notebook/ processors/Pages/notebook-processors.aspx –http://www.intel.com/products/laptop/ processors/index.htm NOTEBOOKCHECK Web site maintains CPU benchmarks for mobile processors continued
Notebook processors, continued Heat dissipation Power management –ACPI Sleep Hibernate Standby –Wireless network connectivity
Notebook drives Hard drive DVD or CD drive Typically no floppy DVD/CD drive might be RW Hard drive –Size: typically smaller than desktop –Small form factor: 2.5" drive –Uses less power than desktop drive –Often slower than desktop drive
LCD monitors LCD technology –Uses less power –Generates less heat –Takes up less space –Produces less glare
Notebook pointing devices Integrated pointing devices –Middle of keyboard –Below keys Types –Small pointer (like a joystick) with separate buttons; below Spacebar –Trackball –Touchpad
Touchpad Glide surface Left button Right button
Notebook ports USB and IEEE 1394 ports VGA, DVI, HDMI ports Memory card readers S-Video Volume controls Line out Microphone port Mute button Microphone port Mute button Volume controls Mute button Volume controls Mute button Line out Volume controls Mute button Line out Volume controls Mute button
Wireless communication Use to link devices: –PCs –Handheld computers –Music players Methods: –Infrared light –Radio waves –Bluetooth
Infrared Pulses of infrared light Up to 16 Mbps 1 meter range Direct line of sight No more than a 30-degree angle
Radio Modulated signals sent over radio waves Not line-of-sight Technologies with varying features –802.11n — Theoretical max. 300 Mbps; real-world speeds 100-140 Mbps –802.11g — Theoretical max. 54 Mbps; real-world speeds 22-24 Mbps RF = radio frequency –Uses antenna; sometimes hidden in case
Bus connections CardBus Zoomed Video eXecute In Place ExpressCard
Notebook memory SODIMM –Approx. half size of regular DIMM –6.76 cm x 3.015 cm –72, 100, 144, 200 or 204 pins MicroDIMM –Smaller than SODIMM –4.25 cm x 2.5 cm –5.4 cm x 3.0 cm –144, 172, 214 pins
Replacing components Refer to manufacturer’s documentation to find panels or slots Document and label screw locations Organize parts Use appropriate hand tools
Hot-swappable components Can be added or removed without turning the computer off Technologies include: –PCMCIA –USB –IEEE 1394 –Fibre Channel –Serial ATA Supported in Windows and Linux
Inserting and removing PC cards Inserting –Insert straight into slot –Pins connect in back of slot Removing –Stop services by using Safely Remove Hardware icon –Press Eject button –Card pops out of slot
Card and socket services Metaformat or Card Information Structure Card Services Socket Services
Non-hot-swappable components Require computer to be shut down Referred to as “coldplug” Often internal components –Memory –Hard disk Unplug the system and remove the battery Always follow ESD precautions
Mini PCI card Same functionality as PCI card, but smaller format Installed inside notebook
Mini PCIe cards Replacing the mini PCI card on mini- ITX system boards Smaller than mini PCI card by approximately half –30 mm x 51 mm 52-pin edge connector System board mini PCIe slot must support both ExpressCard and USB 2.0
Upgrading memory Location in notebook varies by model and manufacturer Most modern notebooks use standard memory modules Some notebooks use proprietary memory When upgrading, consider shared video memory Configure shared memory in BIOS
Replace an optical drive 1.Open drive tray slightly, turn off the notebook, disconnect power cord, remove battery 2.On case bottom, locate and remove screw locking drive in place 3.Slide drive out of socket 4.Insert the new drive 5.Replace locking screw
Keyboard 1.Remove screws holding bottom cover in place. 2.Remove cover. 3.Disconnect connectors that connect the keyboard cables to system board. 4.If keyboard held in by screws, remove the screws. If held in by plastic snaps, gently pry up the edge of the keyboard using a flat-head screwdriver. 5.Gently lift keyboard out. 6.Gently place new keyboard in place. 7.Connect cables to system board. 8.Replace bottom cover and reinsert any screws.
LCD panel and video inverter card Video inverter card – interface between LCD panel and system board If LCD monitor is dim – replace video inverter card If LCD is black – connect external monitor to notebook –External display works, LCD does not – replace LCD panel assembly –External display doesn’t work – replace video adapter card
Disassembling an LCD panel 1.Disconnect the notebook from any external power source and remove the battery. 2.If necessary, remove the keyboard. 3.If necessary, remove screws in the back of the notebook to release the hinge assembly. 4.Remove the hinge covers. 5.Lift the cover off the notebook.
