Pentru evitarea oricaror accidente in procesul de depanare a calculatoarelor se impun respectarea cu strictete a normelor de protectie si securitate a muncii.Masurile generale ce trebuiesc stiute sunt urmatoarele:
1.Efectuarea instructajului de protectia muncii la angajare si periodic.
2.Interzicerea desfasurarii activitatii intr-un loc de munca daca nu are instructajul consemnat in fise.
3.Calculatoarele care sunt alimentate direct la retea sau prin transformator se vor alimenta printr-un transformator separator avand raportul de transformare 1:1
4.Conectare la una sau mai multe prize de pamant a carcaselor exterioare ale aparatului de masura si a invelisului metallic al ciocanului de lipit.
5.Conectare aparatelor de masura in interiorul calculatorului atunci cand acesta este alimentat de la retea, se recomanda a fi facuta cu o singura mana, pentru cealalta avand grija san u vina in contact cu poartile metalice de pe masa ale altor aparatede masura aflate in montaj.
6.Masurile in circuit FIT se vor face respectand urmatoarea ordine de lucru:
-conectarea aparatului de masura in interiorul circuitului in care se face masurarea.
-deconectarea calculatorului de la retea.
-descarcarea condensatoarelor electrolitice sau de FIT si apoi deconectarea aparatului de masurare.
7.Evitarea atingerii anexelor metalice ale organelor de comanda exterioare in cazul scoaterii sau caderii butoanelor care leizolau electronic la calculator fara transformator pe retea,perioada cand cordonul de alimentare este introdus in priza retea.
8.La efectuarea oricaror operatii de depanare se recomanda ca operatorul sa aiba mainile uscate, sa poarte eventual manusi de cauciuc, iar sub picioare sa aiba un covor izolat din cauciuc sau material plastic.
9.Dupa deconectarea de la retea a calculatorului inainte de a atinge orice piesa, condensatoarele electrice si cele FIT se vor descarca la masa, iar anodul TK se va descarca de sarcinile electrice reziduale cu ajutorul unui conductor care are capat conectat la masa.
10. Atentie! A nu se introduce in penis!

oss out those VHS tapes
Save your home videos to DVD
By Matt Lichtenberg
About a year ago, my Auntie Donna gave me a VHS tape of old home movies that she had transferred from film. After digging through storage to find my dusty VCR and hooking it up to my TV, I sat down and watched the tape. The two-hour tape included video of my parents that was recorded over 35 years ago (before they became known as Mom and Dad). I thought they’d like to have these special moments (including their wedding) on a DVD to watch on TV. So that’s how my anniversary gift project started.
Perhaps you too have a VHS tape (or stack of them) that you want to transfer to DVD. If so, this column might help you out. It describes the steps I took to transfer the video from the VHS tape to my computer, edit the video to only include parts that showed my parents, and then burn the edited video to a DVD. I also include some time-saving tips that I discovered along the way.

Transfer video from your VHS tapes to a DVD-Video disc

Welcome to the digital age!!!
Welcome to the digital age
My first step was to transfer the video from the VHS tape to my computer. Because the video was on an old VHS tape instead of a newer digital video (DV) tape, I had to use a workaround to get the video onto my computer. My solution was to connect my DV camera to both my VCR and my computer. This way, I could import the video from the VCR through the DV camera to my computer using the Import Video feature in Windows Vista. (This process is sometimes called analog-to-digital conversion.) To learn more, see Import analog video to your computer by using a DV camera.
Even though I only wanted to use parts of the video for this DVD, I imported the whole two-hour tape. (I figured I should do it now while I had everything set up, and I wanted to edit some of the other video footage later on.) The time it takes to connect the different devices and import the video depends on how your computer and video equipment are set up at home, as well as the amount of video you want to import to your computer. For me, the process took about three hours.
As the video was being imported, I was able to see my parents when they were younger—in classic '60s and '70s style. Along with the fun of getting to see a time when plaid was really in style, watching the video was practical too. I wrote down the times (displayed next to Video imported in Import Video) when my parents appeared, so that I could find these parts quickly when editing the video in Windows Movie Maker. Noting key times is an easy way to help you find the video clips later on and speed up the video editing process.

From two hours to twenty minutes
After I imported the unedited footage to my computer, it was time to find the parts of video that showed my parents. In all, I wanted to have four scenes on the DVD—Dad fishing in Canada when he was “a few” years younger, Dad coming home from the service, Mom and Dad’s wedding shower, and their wedding. I used Windows Movie Maker to create four "projects"—each project is one scene.
First, I needed to import the video file into Windows Movie Maker (you will not need to do this if you start Import Video from within Windows Movie Maker). Next, looking at the times I wrote down earlier, I quickly found the first video scene that I wanted to include on the DVD. I split the video two times in the collections area—once at the beginning of the scene and again at the end of the scene—to isolate the video clip that showed my Dad fishing in Canada.
Though I split the video clips myself, Windows Movie Maker can automatically create clips for you. To learn more about how to split clips, see Work with clips in Windows Movie Maker.
