1 Introduction Unit 2 Computer Systems HND in Computing and Systems Development

2 Unit 2 Practical activities A3 The computer systems are desktops (and a server) LO3 and LO4 Build, configure, test and maintain systems Witness statements wherever possible, photographic evidence Individuals for desktop Pairs for server

3 Criteria LO3 Be able to build and configure computer systems LO4 Be able to undertake routine maintenance on computer systems 3.1 build and configure a computer system to meet a design specification 3.2 test and document a computer system 4.1 perform routine maintenance tasks on a computer system 4.2 upgrade the hardware and software on a computer system.

4 Test plan Normal format Table of tests Table of problems Content POST Mouse/keyboard/monitor/USB ports OS boot, checkdisk, device manager, disk management, event logs, SMART disk analysis (Hiren s boot USB), device drivers Installed software (AV, firewall, camera utilities) Configurations (desktop, storage) Operation of the peripheral

5 Activity Write a test plan Carry out the tasks on the witness statement ACTIVITY ACTIVITY Safe working area Electrostatic precautions Disassemble desktop PC (Note 1 and 2) Install motherboard, CPU, heatsink, fan, memory Install power supply unit Install drives Install graphics card Configure BIOS (date/time, power, security) Install OS Install security applications Configure desktop Configure storage including permissions Connect and install a peripheral Complete all tests on your test plan Note 1: Check correct operation before dismantling. Note 2: One person only to remove CPU, heatsink and fan, document for everybody. Cleaner and thermal paste available for refitting

6 Configuration Date/time Security password on BIOS Boot order: USB, HDD, DVD Screen resolution, large fonts/icons Create additional admin user Create additional standard user Create folder for use by admins only Create task bar shortcut to admin folder

7 Upgrade Unit 2 Computer Systems HND in Computing and Systems Development

8 Criteria LO4 Be able to undertake routine maintenance on computer systems 4.1 perform routine maintenance tasks on a computer system 4.2 upgrade the hardware and software on a computer system. Research motherboard and graphics card specifications INTEL D101GGC Sapphire HD 3650 Check for compatibility Prepare a test plan Prepare the work area Remove the existing graphics card Install the new card Update drivers, adjust resolution and test

9 Witness statement ACTIVITY ACTIVITY Prepared safe area Removal of existing card Installation of new card Install new drivers No errors in device manager Screen resolution adjusted Successful boot

10 Test plan Normal format Table of tests Table of problems Content POST OS boot Drivers installed (device manager check) No errors in device manager Resolutions available (right click desktop)

11 Evidence and clean up Screen shots required Replace old card Roll back drivers

12 Maintenance Unit 2 Computer Systems HND in Computing and Systems Development

13 Learning Outcome 4.0 Be able to undertake routine maintenance on computer systems Software maintenance: upgrade software eg virus definition files; patches/updates; scheduling maintenance tasks; utility software eg defragmentation, clean-up, back-up, system profilers; other third party utility software eg compression utilities, spyware/malware removal Hardware maintenance: upgrade hardware; install and configure new peripherals eg printers, scanners; install and configure additional or replacement devices eg hard drive, memory, graphics, sound, optical media, network; cleaning equipment File management: manage files/folders; back-up procedures

14 Learning outcomes LO4 Be able to undertake routine maintenance on computer systems 4.1 perform routine maintenance tasks on a computer system 4.2 upgrade the hardware and software on a computer system Mainly assessed by witness statement

15 Maintenance schedules (for a heavily used machine) Daily Weekly Monthly 6 months Yearly Security Clean up Anti malware quick scan Clean temp files Anti malware full scan C: Verify malware up to date Verify firewall Check updates Change passwords Clean registry Data integrity Backup Verify backup Full backup or image Disk health Hardware Quick defragment C: CHKDSK C: Full defragment C: Full defragment C: CHKDSK all disks Check free space Remove obsolete files Full defragment all disks SMART check all disks Clean Check BIOS Uninstall unused applications Check batteries

16 Witness statement ACTIVITY ACTIVITY Anti-malware scan Verify firewall Check updates Change passwords Clean temporary files Clean the registry Remove obsolete files Uninstall unused applications Take and verify a backup Defragment hard disk CHKDSK and SMART all disks Check BIOS updates Check driver updates Clean and remove dust (Proliant)

17 Automation Several of the activities in the schedule can be automated When you do the tasks on the witness statement you need to use automation wherever possible Task scheduler Policies

18 Desktops Individually perform the majority of activities on your virtual desktop or the lab desktop Take screen shots as evidence If you don t know the procedures, research them

19 Server HP Proliant used for cleaning exercise Maintenance manual on studshare in HND folder Refer to the manual for disassembly procedures Work in pairs to identify and photograph all dirty areas that require cleaning, then reassemble Do NOT clean it (needed for next group) Assignment will require you to identify cleaning methods to be used
