– Power Supply AT – Power Supply ATX.

• Power Supply AT: is the Power Supply that has– Two connector to mainboard– Power Button– Not Shutdown Automatically( When you Click Start => shutdown=>

it displays message “it’s now safe to turn of your computer” you can press Power Button to Shutdown)

• Power Supply ATX: is the power Supply that has– One Connect to Mainboard– No power Button– Shutdown Automatically


• Note – If your computer use power supply ATX but ,

it doesn’t shutdown Automatically so you change it to shutdown automatically :

– ( start =>setting => control panel=> Power option =>APM=> you tick Enable Advanced Power management Support =>OK.)


Power Supply Power Supply • Connector Power supply

– Power supply AT has 8 connectors:• The same 2 big Connectors: used to connect to mainboard• The same 4 big Connectors : Used to connect to (HDD,

•Definition– Jumpers allow the computer to close an electrical circuit allowing the

electricity to flow throughout certain sections of the circuit board. Generally, the jumpers consist of a set small pins which can be covered with a small plastic box. This box connects the two pins together allowing the electricity to flow freely between the two pins.

– Jumpers are used to configure computer peripherals such as Hard Drives, Modems, Sound Cards, and various other components. For example, when installing a new hard drive, you may need to change the jumper settings depending if the hard drive is a master drive or a slave drive.

DIP SwitchDIP Switch• Dip switches are designed with the

same intentions as jumpers. However, instead of having to remove the jumper block and placing it over separate pins, dip switches are actual small switches which can be turned to the ON or OFF position.

• Like jumpers, Dip Switches are used to configure computer peripherals such as Hard Drives, Modems, Sound Cards, and various other components. Generally, however, Dip Switches are usually only found on PC Boards such as the Motherboard, Sound Card, or other PC Boards.

- Master(M): Used to configure First running of HDD-Slave (S):Used to cofigure the second running of HDD-Cable Selector(CS): Used to configure the last Running of

HDD

• Note– If two HDDs connect to only one

IDE we have to check jumper on HDD before connect.

– If two HDD connect to deferent IDE we do not need to check jumper.

– When we connect CD-ROM, CD-RW, DVD-ROM, DVDRW,and HDD together we have to check them like above.

Jumper on mainboardJumper on mainboard

• Jumper on mainboard TXPro II– JP4:clear CMOS Memory

– Note: you can see jumper clear CMOS • it is near the CMOS Battery• There are 3 or 4 pins of jumper• Use the words”Normal, Default, Battery on, Clear CMOS”

Normal (mainboard works normally)

Clear CMOS Memory(mainboard does not work )

• Note– If sound build on board and mainboard has jumper for

sound when we install sound card we have to disable sound on board.

– If sound build on board but mainboard has no jumper when we install sound card it will disable on board sound automatically.

– If sound build on board but mainboard has no jumper some maimbord, when we install sound card they all work but we have to select Driver that we want to use.


• Start => setting => control panel=>sound and audio device=>audio=> ( select driver you want to use )=> ok

Ms DOS(Miscorsoft Disk Ms DOS(Miscorsoft Disk Operating System)Operating System)

• Definition– Ms Dos is the operating system that run by typing command .– FOR computer repair use ms dos to prepare hard disk to store data.

• Kind of ms dos– Ms dos mode – Ms dos prompt


Kind of Ms dos Kind of Ms dos – Ms dos mode is the ms dos dos that run not depend on windows– Ms dos prompt is ms dos run on windows

• How to Open Ms dos – Ms dos mode

• Use CD boot or diskette boot (power on => CMOS =>BOOT from CD-ROM=> insert CD BOOT)

– MS DOS PROMPT– WINDOW 95,98

– Start => Run => command=>ok– Start=>program=> ms dos prompt– Power on =>f8=> command Prompt only

– Windows me– Start => Run => command=>ok– Start=>program=> Accessory =>command prompt

– Window 2000,XP– Start => Run => command or cmd=>ok– Start=>program=> Accessory =>command prompt– Power on =>f8=>safe mode with command Prompt


notenote

• We always use ms dos mode in computer repair because the HDD is not store windows yet, so we have to prepare HDD to store data with ms DOS mode the run from CD BOOT or diskette.
