Versatile PCs Chapter 14

Slide 2

Overview In this part, you will figure out how to Describe the numerous sorts of convenient registering gadgets accessible Enhance and redesign compact PCs Troubleshoot compact PCs

Slide 3

Portable Computing Devices

Slide 4

What\'s in a Name? What\'s the contrast between a convenient, a portable workstation, and a journal? Nothing! There\'s no industry standard for names However, most note pads are tablets in the 8 ½ x 11-inch range

Slide 5

Desktop Replacements Typical tablets capacity as a completely standalone PC which might be considered a desktop substitution Input gadgets Trackballs on early tablets IBM\'s TrackPoint pencil eraser-sized joystick in the center of the console Touchpads LCD screens

Slide 6

Desktop Extenders Desktop extenders are versatile gadgets that are not proposed to replace a desktop Think of them as a littler, lighter, less effective portable PC for less serious uses

Slide 7

PDAs Personal Digital Assistants ( PDA s) are small, hand-held compact figuring gadgets Address book, individual notes, arrangements, word processors, picture viewers Often utilize penmanship acknowledgment with a pen-style stylus for pen-based registering Uses specific OSs, for example, Windows CE, PocketPC, PalmOS, and Linux Made by Palm, Sony, Toshiba, Hewlett-Packard, Microsoft and different organizations

Slide 8

HotSync You can undoubtedly synchronize your information on your PDA with your office PC Just put it on your support by the PC and snap the catch to synchronize PDA Memory Internal blaze ROM of 1 MB or more Compact Flash cards that are removable and upgradable for removable stockpiling needs HotSync & PDA Memory

Slide 9

Enhance and Upgrade the Portable PC

Slide 10

PC Cards PC Cards are ordinarily known as the Personal Computer Memory Card International Association ( PCMCIA ) Hot-swappable gadgets that play out each PC work Easy to utilize, economical, and helpful

Slide 11

PC Cards CardBus card is a 32-bit PC Card with a unique opening PCI transport acing Can perform up to 8 capacities contrasted and 2 capacities for a consistent PC card, (for example, a modem and system card consolidated) Regular PC cards will work in a CardBus space CardBus utilizes 3.3 volts of force – customary PC cards utilize 5 volts

Slide 12

PC Cards Two levels of programming drivers Socket administrations Device drivers that empower the framework to distinguish when a PC Card is embedded or expelled, and give vital I/O to the gadget Standardized and took care of by the framework BIOS Card administrations Recognize the capacity of a specific PC Card and give the particular drivers required to make the card work Handled by Windows Accessed by means of PCMCIA alternative in Control Panel

Slide 13

PC Card Types

Slide 14

Limited-Function Ports All convenient PCs and numerous PDAs accompany an assortment of ports VGA association for attaching an outer screen PS/2 port for an outside console or mouse Speaker ports Built-in NICs and modems for system bolster All of these work the same as in desktop PCs Video ports Allow showing the tablet LCD, the outer screen, a projector, or a blend Extra capacity key (like the Control or Alt keys)

Slide 15

General-Purpose Ports USB ports Support up to 127 gadgets Usually most USB sharing is constrained to 3 or 4 gadgets 12 Mbps throughput Maximum link length of 5 meters just Due to electrical obstruction, it\'s ideal to stay around 2 meters greatest Hi-Speed USB Backwards perfect with consistent USB 480 Mbps throughput

Slide 16

USB Configuration Ensure that the CMOS gives an IRQ to USB ports Ensure that the working framework underpins USB All variants of Windows from Win95B and more up to date (aside from NT) support USB Always introduce gadget drivers before connecting to another USB gadget

Slide 17

Port Replicators Port replicators are gadgets that fitting into a USB port and offer basic PC ports, for example, serial, parallel, system, and PS/2

Slide 18

Docking Stations Easily gives portable workstations access to expansive screens, customary mice, system associations, full size consoles Provides a simple approach to remove your tablet in and from the workplace Basically a port replicator with additional elements, for example, a DVD drive or PC Card openings

Slide 19

FireWire has speedier exchange rates than USB Uses a 6-pin controlled connector that can give energy to an appended gadget (like USB) Or a 4-pin unpowered connector

Slide 20

The Modular Laptop

Slide 21

The Modular Laptop The basic segments that can be supplanted or redesigned in a compact PC are: RAM 72-pin or 144-stick SO-DIMMs Hard drives ATA drives in the 2.5-inch group command portable PCs today Check for the best possible settings (Cable Select, Master, Slave) yet generally the same as general 3.5-inch drives Modular CPUs Just supplant with a fresher module from Intel or AMD Video cards Least institutionalized

Slide 22

Replacing RAM There\'s no standard yet you as a rule need to unscrew or pop open a board on the underside of the versatile

Slide 23

Modular Drives Laptop makers may incorporate secluded drives that might be swapped in and out CD-ROM DVD-ROM CD-R/W Floppy plate drives

Slide 24

Managing and Maintaining Portables

Slide 25

Maintenance Everything you ordinarily do to keep up a PC applies to compact PCs Windows fixes and Service Packs Upgraded drivers Check Disk ScanDisk Defragment Disk Cleanup

Slide 26

Batteries Types of Batteries Nickel-Cadmium (Ni-Cd) Nickel Metal Hydride (Ni-MH) Lithium Ion (Li-Ion)

Slide 27

Nickel-Cadmium Batteries Nickel-Cadmium ( Ni-Cd ) batteries were the primary batteries normally utilized as a part of versatile PCs Provide an enduring voltage yet subject to battery memory issue Battery memory is the inclination of a Ni-Cd battery to lose a lot of its energize capacity if charged more than once without being completely released To dodge this issue, these batteries must be released totally before each reviving Susceptible to self-release after some time

Slide 28

Nickel Metal Hydride Nickel Metal Hydride ( Ni-MH ) batteries were the up and coming era of versatile PC batteries Less defenseless to memory issues and last more between revives Still vulnerable to warm Popular trade for Ni-CD frameworks

Slide 29

Lithium Ion Lithium Ion is the most widely recognized kind of battery utilized today Powerful and totally insusceptible to memory issues Built-in hardware to avert incidental cheating

Slide 30

Other Portable Power Sources Smart batteries advise the PC when they should be charged, molded, or supplanted Fuel cells are a promising new innovation that could control a portable workstation for up to 40 hours before refilling

Slide 31

Battery Maintenance Batteries ought to be put away in a cool spot Ni-Cd and Ni-MH batteries ought to be adapted by utilizing a charger Battery contacts ought to be kept clean utilizing a little liquor or dry fabric Used or old batteries ought to be reused

Slide 32

Power Management

Slide 33

Power Management Power Management must Shut down unused gadgets specifically Define a greatest time of inertia Shut down the whole framework amid longer times of latency Ready to restart if activated by a wake-up occasion Sensitive to potential dangers like closing down the hard drive amidst a compose operation Keep the framework cost about the same

Slide 34

System Management Mode System Management Mode ( SMM ) is an arrangement of elements that empowers the CPU to back off or stop its clock without erasing the register data Stops the CPU and the greater part of the peripherals Requires a specific BIOS and OS To further power administration abilities, Intel presented Advanced Power Management ( APM ) in 1992 and Advanced Configuration and Power Interface ( ACPI ) in 1996

Slide 35

Requirements for APM/ACPI APM and ACPI require the accompanying to work appropriately A SMM-fit CPU APM-agreeable BIOS Devices that will acknowledge being stopped ("Energy Star") A framework OS that knows how to ask for the close down of a specific gadget

Slide 36

APM/ACPI Levels Full On No force administration – everything running at full power APM Enabled CPU and RAM running at full power Unused gadget might possibly be closed down APM Standby CPU is halted RAM still stores every one of the projects All peripherals are closed down APM Suspend Everything is closed down or at its least power-utilization Hibernation (stores everything in RAM on the hard drive before shutting down)

Slide 38

Configuration of APM/ACPI –Windows

Slide 39

Cleaning Use a screen cleaner to clean the LCD screen (not a glass cleaner!) Compressed air to get out the console and PC Card attachments Heat Use power administration Keep air space between the base of the portable PC and the surface it sits on Don\'t utilize a console defender Listen for your fan running a ton – on the off chance that it is permit your tablet to chill Cleaning & Heat
