IN this ar­ti­cle, we will be­gin to learn about com­puter hard­ware ser­vic­ing which is part of the In­for­ma­tion and Com­mu­ni­ca­tions Tech­nol­ogy (ICT) com­po­nent of Tech­nol­ogy and Liveli­hood Ed­u­ca­tion (TLE) sub­ject in school.

As a short in­tro­duc­tion and re­call about ICT, UNESCO is pos­i­tive about learn­ing ICT in school will con­trib­ute to uni­ver­sal ac­cess to ed­u­ca­tion, eq­uity in ed­u­ca­tion, the de­liv­ery of qual­ity learn­ing and teach­ing, teach­ers’ pro­fes­sional de­vel­op­ment and more ef­fi­cient ed­u­ca­tion man­age­ment, gov­er­nance and ad­min­is­tra­tion. This is par­tic­u­larly pos­si­ble through learn­ing com­puter hard­ware ser­vic­ing which is likely ben­e­fi­cial es­pe­cially for learn­ers from the coun­try­side in the Philip­pines.

Com­puter hard­ware ser­vic­ing is a blan­ket term ap­plied to the act of sup­port­ing and main­tain­ing com­puter hard­ware. This in­cludes di­ag­nos­ing com­puter hard­ware is­sues, up­grad­ing hard­ware on a com­puter and re­pair­ing com­puter hard­ware. A pro­fes­sional in charge of com­puter hard­ware main­te­nance must be able to per­form the fol­low­ing tasks: (1) in­stall per­sonal com­puter (PC) hard­ware; and, (2) di­ag­nose com­puter hard­ware prob­lems. In­stalling PC hard­ware whether desk­top or lap­top, a stu­dent must learn how to in­stall and how to up­date hard­ware driv­ers.

The les­son on com­puter hard­ware ser­vic­ing will pro­vide de­tailed step by step in­for­ma­tion about how this can be done but be­low are the im­por­tant items that needs to be checked: pro­ces­sor, drive, ex­pan­sion card, key­board, moth­er­board, mouse, power sup­ply, mem­ory, printer and scan­ner. But the most im­por­tant thing that we need to note be­fore in­stalling any hard­ware in­side a com­puter is to open the com­puter and be aware of Elec­tro Static Dis­charge (ESD) and its po­ten­tial dan­gers.

Many peo­ple are faced with ev­ery­day com­puter prob­lems that are easy to fix, but are un­able to di­ag­nose the ac­tual prob­lem. While there are many prob­lems a com­puter will be faced with, this ar­ti­cle will tell you where to look for com­mon prob­lems.

The fol­low­ing needs to be checked in or­der to di­ag­nose a com­puter hard­ware prob­lem: (1) Check for Power On Self Test or POST; (2) No­tice the load time of the OS (op­er­at­ing sys­tem); (3) No­tice any graph­ics prob­lems once the OS has loaded; (4) Per­form an au­di­tory test; (5) Check any newly in­stalled hard­ware; (6) Check any newly in­stalled soft­ware; (7) Check RAM and CPU con­sump­tion; (8) Lis­ten to the com­puter, if the hard drive is scratch­ing or mak­ing loud noises, shut off the com­puter and have a pro­fes­sional di­ag­nose the hard drive; (9) Run a virus and malware scan; and, (10) Check for the prob­lem in safe mode.

Ac­cord­ing to ex­perts, in­di­vid­u­als with ex­per­tise in com­puter hard­ware ser­vic­ing can ex­pect to see the field in­crease by 30 per­cent by 2018. Much of this in­crease will be seen in the field of net­work en­gi­neer­ing, the field size of which is pro­jected to in­crease by 50 per­cent. But even if one has earned com­puter hard­ware ser­vic­ing skills in the coun­try­side, this prom­ises a good source of liveli­hood al­ready.

A well- taught com­puter hard­ware ser­vic­ing topic in TLE sub­ject in school can in­spire stu­dents pur­sue higher stud­ies that will make them be­come com­puter tech­ni­cian, IT tech­ni­cal sup­port of­fi­cer, tech­ni­cal sup­port rep­re­sen­ta­tive, and com­puter hard­ware spe­cial­ist.
