Do you know what to do if your screen goes blank? What if you can't seem to close an application, or can't hear any sound from your speakers? Whenever you have a problem with your computer, don't panic!

Computer maintenance is the practice of keeping computers in a good state of repair. A computer containing accumulated dust and debris may not run properly. Dust and debris will accumulate as a result of air cooling. Any filters used to mitigate this need regular service and changes.

Well-maintained devices last years longer than maltreated equivalents, supporting smooth personal and professional use patterns and keeping more of your hard-earned money in your wallet along the way. These electronic device maintenance tips are all well within the capabilities of the typical non-expert computer user. Some are tailored to desktops and laptops. Others apply to a broader range of devices.

Most are best done on a recurring basis. And none require excessive investments of time, effort, or money. A dirty keyboard will eventually stop working properly.

Ditto for a dirty mouse. Dusty or particle-clogged ports reduce airflow into and out of the device, increasing the risk of overheating. Dust it periodically with a microfiber cloth. After prematurely KOing two keyboards in rapid succession, I instituted a new rule in my household: nothing but water on the same surface as my laptop.

I highly recommend you do the same. If you have an active home office setup, it probably features a mess of cords, power strips, and random accessories on the floors and working surfaces. This mess is unsightly and unwieldy at minimum. If you have small children or pets, it may well present an electrocution risk. Depending on how loaded-up your power strips and outlets are, you could have a fire hazard on your hands.

And jumbled cords are more vulnerable to damage, meaning higher long-term ownership costs. Fixing this is easy. Unplug, detangle, and reorient your cords in your handy new organization system. Then plug everything back in. Pro Tip : Seeking more home office hacks? Resist the temptation to keep your portable devices plugged in at all times. If you have a desktop, keep the tower clear of any obstructions, like cabinets or walls. For laptops, maintain a clear workspace free from clutter that could obstruct airflow — for instance, papers or books.

Periodically check that the fans are working as well. No matter what kind of device you have, maintain adequate ventilation and reasonable climate control. Rice is merely the best desiccant, or drying agent, that most people have lying around the home. As it turns out, there are products made specifically to mop moisture out of electronics. An even cheaper alternative: the little silica gel bags that come in many shipping boxes.

Rather than throwing them out, collect them as they come in, taking care to store them somewhere child- and pet-proof. Keep your home office — and your devices themselves — away from magnets, even the weak refrigerator kinds. Your hard drive is incredibly sensitive to magnetic fields of any strength. If you need to remember websites or phone numbers, use Post-it notes or digital files instead. Keep magnets where they belong — in the kitchen. Be wary of unsecured WiFi networks in coffee shops, airports, hotel lobbies, and other public places.

Without basic network security, your computer is a sitting duck — out there in the open for any hacker or cyber criminal who feels like sending a malware package your way. When in doubt, use a virtual private network VPN to encrypt your connection and repel attacks.

My wife cracked her last three screens, all under relatively mundane circumstances. Phones are resilient, but not indestructible. The choice between purchasing a brand new phone or buying a protective enclosure to deflect kinetic energy is no choice at all.

Ditto for screen protectors. Bake this into your nightly routine. Also, how you shut down matters. I personally only shut down my smartphone for updates, since I like to be available for emergency calls and alerts through the night.

With rare exceptions, it should always be up and running. Generally, you should avoid downloading any files from an unverified source. Turning on your firewall is easy. Mac OSX v This is an issue with certain multiplayer games and older versions of Apple iTunes, for instance. Though some such programs are essential system processes, many are trivial and can safely be deleted. You can address some bloatware-related issues by running a free system cleaner like CCleaner.

For best results, you need to manually uninstall bloatware — and you need to do it right. Deleting program icons is not the proper way to remove unnecessary programs from your computer. You need to execute a formal uninstall process for every single application you want to get rid of.

Cult of Mac has a good overview of trickier Mac uninstalls , for instance. Your job or hobby might require you to download or create and store large multimedia files. Yes and no.

An external hard drive is your best, and cheapest, bet. Drive cost has moved in near-inverse proportion to drive capacity. Novel malware crops up just as fast as white hats neutralize it. Enter the system-wide malware scan. You should periodically run malware scans, ideally with more frequency than bloatware checks. PC World recommends using Malwarebytes to scan your system, but there are other options. The best way to protect your computer from malware in the first place is to use a high-quality anti-malware program.

This is especially important for PCs, which are more vulnerable to viruses, worms, and other malware. New laptops and PCs generally come with anti-malware software preinstalled or at least included in the package, but be wary of accepting it at face value.

Some anti-malware software may cause more problems than it solves. This routine exercise requires minimal buy-in on your end — patches and updates generally install themselves when your computer is off or asleep. One way to make sure you stay on schedule is to shut off your computer regularly. Updates only go so far, and too many layered updates can actually be counterproductive.

Microsoft has more about its Windows reinstaller tool here. Just make sure you reinstall any necessary applications too. Always keep original install media handy, or at least know where to find them. The added convenience might be worth the cost. When the time finally does come to rid yourself of an old electronic device, please do so responsibly.

In my hometown of Minneapolis , a fantastic organization called Tech Dump has rescued tens of thousands of old devices from landfills since its founding — including about a dozen from my household alone.

Basic computer troubleshooting

Preventive maintenance is something that is often overlooked, but good IT professionals understand the importance of regular and systematic inspection, cleaning, and replacement of worn parts, materials, and systems. Effective preventive maintenance reduces part, material, and system faults, and keeps hardware and software in good working condition. Performing basic tasks like checking what programs run on start-up, scanning for malware, and removing unused programs helps a computer function more efficiently, and can keep it from slowing down. Good IT professionals also understand the importance of troubleshooting which requires an organized and logical approach to problems with computers and other components.

Computers play a vital role in our lives, which is why it is crucial that you take care of them. We use them daily to pay bills, stream videos online, play games, surf the internet, research for school assignments, and that is just on our own time. Most people need computers to get their professional work done as well. Computer maintenance is very important for keeping your computer running smoothly.

4.0 – Introduction

Этот человек сломал запястье, у него травма головы. Он был принят сегодня утром. Его карточка должна лежать где-то сверху. Беккер еще больше усилил акцент, но так, чтобы собеседница могла понять, что ему нужно, и говорил слегка сбивчиво, подчеркивая свою крайнюю озабоченность. Люди часто нарушают правила, когда сталкиваются с подобной настойчивостью. Но вместо того чтобы нарушить правила, женщина выругала самоуверенного североамериканца и отсоединилась. Расстроенный, Беккер повесил трубку.

 Eh. - Una nina? - повторил Беккер.  - Pelo rojo, azul, y bianco. Красно-бело-синие волосы. Мужчина засмеялся: - Que fea. Ничего себе зрелище.

Он прислушался. Голоса звучали возбужденно. - Мидж. Ответа не последовало. Бринкерхофф подошел к кабинету. Голоса показались ему знакомыми. Он толкнул дверь.

У нас очень строгие правила относительно контактов клиента и сопровождающего. - Но… - Вы спутали нас с кем-то другим.

 - Голос послышался совсем. - Ни за. Ты же меня прихлопнешь.

Фонтейн почти во всем полагался на Стратмора и верил в его план, в том числе и в достойную сожаления, но неизбежную необходимость устранять Энсея Танкадо и в переделку Цифровой крепости, - все это было правильно. Но одно не давало Фонтейну покоя - то, что Стратмор решил прибегнуть к услугам Халохота. Тот, конечно, был мастером своего дела, но наемник остается наемником. Можно ли ему доверять. А не заберет ли он ключ .

Он хотел его оставить, но я сказала. Во мне течет цыганская кровь, мы, цыганки, не только рыжеволосые, но еще и очень суеверные. Кольцо, которое отдает умирающий, - дурная примета. - Вы знаете эту девушку? - Беккер приступил к допросу. Брови Росио выгнулись.

Introduction to Computer Maintenance and Troubleshooting A+, Chapter 4

Все подняли головы.

Других слов для него у нее не. Стратмор оторвался от перил и переложил пистолет в правую руку. Не произнеся ни слова, он шагнул в темноту, Сьюзан изо всех сил держалась за его плечо. Если она потеряет с ним контакт, ей придется его позвать, и тогда Хейл может их услышать.

Словно по сигналу, поданному инстинктом выживания, все мышцы его тела моментально напряглись. Он взмыл в воздух в тот момент, когда раздался выстрел, и упал прямо на Меган. Пуля ударилась в стену точно над .

Выглянув в пустую шифровалку, он принял решение. На загрузку программы и поиск вируса уйдет минут пятнадцать. Скажи, что ничего нет, - прошептал.  - Абсолютно .

Кольцо, которое отдает умирающий, - дурная примета. - Вы знаете эту девушку? - Беккер приступил к допросу. Брови Росио выгнулись.

 - У него был врожденный порок сердца. - Никогда об этом не слышала. - Так записано в его медицинской карточке. Он не очень-то об этом распространялся. Сьюзан трудно было поверить в такое удачное совпадение.

Как только он оказался там, его сразу же увлек за собой поток молодых людей. - А ну с дороги, пидор! - Некое существо с прической, больше всего напоминающей подушечку для иголок, прошествовало мимо, толкнув Беккера в бок. - Хорошенький! - крикнул еще один, сильно дернув его за галстук. - Хочешь со мной переспать? - Теперь на Беккера смотрела юная девица, похожая на персонаж фильма ужасов Рассвет мертвецов. Темнота коридора перетекла в просторное цементное помещение, пропитанное запахом пота и алкоголя, и Беккеру открылась абсолютно сюрреалистическая картина: в глубокой пещере двигались, слившись в сплошную массу, сотни человеческих тел.

 Нет, - хмуро сказал Стратмор.  - Танкадо потребовал ТРАНСТЕКСТ. - ТРАНСТЕКСТ.

Сьюзан еще раз прочитала адрес на клочке бумаги и ввела информацию в соответствующее поле, посмеялась про себя, вспомнив о трудностях, с которыми столкнулся Стратмор, пытаясь самолично запустить Следопыта. Скорее всего он проделал это дважды и каждый раз получал адрес Танкадо, а не Северной Дакоты. Элементарная ошибка, подумала Сьюзан, Стратмор, по-видимому, поменял местами поля информации, и Следопыт искал учетные данные совсем не того пользователя. Она завершила ввод данных и запустила Следопыта.

Отключить ТРАНСТЕКСТТеперь это нетрудная задача, поскольку она находится возле командного терминала. Она вызвала нужное командное окно и напечатала: ВЫКЛЮЧИТЬ КОМПЬЮТЕР Палец привычно потянулся к клавише Ввод. - Сьюзан! - рявкнул голос у нее за спиной. Она в страхе повернулась, думая, что это Хейл.
