Laptop Components- Outside Bluetooth Battery Standby Reduces electricity Shuts off monitor, hard drive, CPU Little left for RAM so you can resume

Laptop Components- Outside Back Battery Parallel AC VGA

Types of Batteries NiCd NiMH Li-Ion Li-Poly Heavy, memory effect Moderate weight, no memory effect, only so many charges Li-Ion Light, no memory effect, gets hot, get freshest Li-Poly $$, light, small, charge fast

Laptop Components- Outside Side Kensington Lock USB Ports S-Video 4-pin Sends video only RJ11 Modem RJ45 Ethernet Ethernet LED Connect LED Traffic LED Audio Jacks Green- Spkr/Hdph Pink- Mic Vent Expansion Slot PC Card (old) & Express Card (new) Modem & Ethernet are for communications, PCI is on desktop only, PC Card/Express Card laptop only PC Card/Express allow you to expand a laptop like you would a desktop PC Card is hot swappable as well as USB. Optical Drive may be also. What does hot swappable mean?

Laptop Components- Outside Front Infrared Port Short range, printer Speakers Sometimes on top Latch to open it More vents

Laptop Components- Other Side Optical Drive VGA Port Others: HDMI eSATA Firewire Card Reader

Laptop vs. Desktop Compare and contrast desktop and laptop motherboards. Compare and contrast desktop and laptop processors. Compare and contrast desktop and laptop power management. Compare and contrast desktop and laptop expansion capabilities.

Laptop vs. Desktop Compare & contrast

Laptop vs. Desktop Laptop MB proprietary SoDIMM

Laptop vs. Desktop- CPU Laptop CPU designed for less power & heat CPU Throttling Changes speed to reduce heat & power Allows for longer use on battery power Mobile processors May be less speed

Laptop vs. Desktop- Power Options Always plugged in Battery keeps BIOS/clock running Laptop DC power (AC to DC convertor) Advanced Power Management (APM) OLD Bios controlled settings Advanced Configuration and Power Interface (ACPI) The OS controls power management

Laptop vs. Desktop- Expansion Internal bays of 3.5” & 5.25” PCI Slots USB, FireWire Laptop PC Card expansion- OLD Hot-swap bays

Types of Expansion- Storage Storage Devices Magnetic Moving parts Flash SSD Optical CD- 700MB DVD- 8.5GB per side BD- 25GB per side

Types of Expansion- Slots PCMCIA/PC Card- OLD All 54mm wide Type I 16-bit, slow, 3.3mm thick PDA memory expansion only Type II 16 or 32-bit, 5.0mm thick I/O devices like modems with dongles Type III 10.5mm thick I/O devices without dongle use

Types of Expansion- Slots PC ExpressCards Replaced PCMCIA Faster throughput 34 or 54mm wide, 5mm thin Hot-pluggable Replaced by USB 2.0/3.0

How to Configure Laptops Describe how to configure power settings. Describe the safe installation and removal of laptop components.

Configure Power Settings- BIOS ACPI Standards Help create a power scheme (plan) to maximize battery/computer performance In BIOS Under Power Must be enabled in order to configure in Windows Using battery power is important. Batteries can last 2-10 hours, depending on the type of battery. Managing that power is important. Advanced Configuration and Power Interface.

ACPI States S0- On & CPU running S1- CPU/RAM get power, unused devices not S2- CPU off S3- Suspend (XP)/Sleep (Vista/7), RAM gets power S4- Hibernate, RAM contents saved to file in HD S5- Off

Configure Power Settings- OS In Control Panel, Power Options Hard drive Display Shut Down, Hibernate, and Suspend/Sleep modes Low-battery warnings What do you think consumes a lot of the battery power in laptops? Hard drive & Display

Power Schemes/Plans Use preset or customize Notice you can set the hard drive to stop spinning after a period of inactivity when plugged in or on battery. Same thing with the display. You can even set low battery or critical battery “alarms” or warnings when battery reaches a certain percentage of life left.

Laptop Power Options XP Vista/7 Standby – Docs & apps saved in RAM; powers on quickly Hibernate – Docs & apps saved to a temp file on HD; takes a little longer than Standby to power on Vista/7 Sleep – Just like Standby Hibernate
