Computer Repair

In case of failure the power supply the correct choice for computer repair – replacement power supply for a new one. However, we consider the most common causes of failure of power supplies. Computer Services, with experience of more than 5 years gives the following recommendations: The most likely breakdown diode rectifier bridge to high-voltage circuit. Power supply for such a defect is completely dead: there is not one of supply voltages (including the "duty" of five volts), and inclusion – no sounds and movements. The reason is determined by any ohmmeter: if the resistance between any two terminals of the diode bridge is less than 1 ohm and the same in both directions – the bridge needs to be changed.

Incidentally need to be replaced and a fuse for these breakdowns it is usually consumed, unless the food chain computer was not protected by circuit breaker is activated quickly. As a replacement suit almost any rectifier bridge or individual diodes, the voltage above 300 volts and a current of 1 amp, but does not include meals in a hurry – perhaps deeper reason. Second on the extent of failure – the breakdown of separate diodes in secondary rectifier circuits. External manifestations of such a failure – the existence of "duty" of voltage and weak signs of life: when you press the power button the fan once twitches, but nothing more occurs. In this case, the actual converter is working normally. Will help you ohmmeter: punched diode or diode assembly is easy to detect, not by almost zero resistance in both directions. If you using a multimeter, which allows you to check the serviceability of the diodes by measuring the forward voltage drop, do not be surprised too low for such diode arrays main channels – where applicable Schottky diodes with a drop of about 0.1 volts. Unfortunately, the assembly on the Schottky diodes can be replaced only similar, ordinary diodes here will not help – they have too much power dissipation, in addition, will be considerable variation stresses in the channels.

In the negative supply chains, the normal diode, but do not forget that the converter operates at a frequency of 200 , so that the diodes should be high frequency. Another part of the reasons for exit block Power failure can be determined visually, these include the breakdown of electrolytic capacitors (rupture of the shell, more often – from the top) and protective varistors. Capacitors, of course, be changed, and varistors – because it does not there is always the same – you can just vypayat (remembering that the unit is left without protection from the next major power surge). Breakdown of high-transistor, which is a few years ago it was possible put in the first place, now rare: the element base is not static, and the current transistors rarely fail on their own. There are other possible reasons, but for their diagnosis would take at least oscilloscope, and connect with their removal is economically inexpedient. In any case it is better to trust computer repair professionals.

Investment Fund

If yours, yours is not having your money in the Bank, investment funds may be the best option for you. But really what is the difference between having the money in an investment fund operator or an investment funds Manager? First to nothing, the operator only offers you products say your brand, while the administrator has different options for you to choose. If you don’t have enough money to buy shares on the stock exchange of different and important Mexican companies, you have the excellent choice of putting your money into mutual funds. These funds, we can say that they are like having your money in a little piggy, well kept, but also where there is someone who cares for him and gun packages of bonds that you can get more money to the little piggy. Code.org is often quoted on this topic. Since you put the money to the little piggy you desentiendes for a moment, because experts are responsible for buying and selling with fewer committees because everything is divided among all the people who put their money at the same little piggy than you. By things like which they talked above, I can say that investment funds often are much better option that having your money simply in the Bank. Although it implies some kind of risk that would maybe having money in the Bank don’t you bring, the remuneration may be much more positive. In Mexico there are more or less 400 investment funds different, looking for which you think that is your best option to invest your money in mutual funds..

Tips For A Successful Holiday In India

Here are some truths that everyone should know: – worry about their beauty in India is certainly not necessary! There is enough money to care for hair and body. Excellent products based on plant components, without fat and chemicals (only a natural product!) – this technology is applied in this country for hundreds of years. – With regard to vaccination: if to leave for India (Goa) on one or two weeks, then do vaccination is possible, but not necessarily. If you still have gathered to make it, do it in advance (at least 20 days before departure). All the recommended vaccinations, you can ask your tour operator or the nearest medical center. – No problem in India is not and that your trip is not clouded by any misunderstandings simply follow the standard rules of hygiene: wash your hands after walks, before eating, wash fruits / vegetables before eating; drink only boiled water or water from the store, take a shower after swimming in open water, cuts / scratches / abrasions treat the wound with antiseptic – in general, as in all other countries =) – Only one major Note: some of the medicines in India do not, at this if you have allergies – Take the cure for allergies, you can take aspirin or any other means of light headaches. Take a sterile band-aid and bandages. And also: 1.

Features of culinary delights in India can someone cause stomach upset with (habit) – bring your activated carbon and festal. 2. Immediately bring at least a small bottle of sunblock, unprepared skin can be burnt in the sun in the first hours after leaving the airport. 3. You can take with ointment or spray for mosquitoes – if you're a fan of sleeping in a hammock outside. 4. Girls – all necessary means to personal care taken with you, so do not run around town in a piquant moment 5. Boys – contraceptives, too, have a better homeland. Happy holidays!

The Broth Was Cooled, Free Software Cooking Remains Half

As our president, what is happening, my God, because believe it or not and despite that, what free software is a mandatory decree, in the public administration, and nobody is moving, even some supporters CIOs Decree are disappearing, being sent into oblivion or to the gallows by their own superiors, who seek any justification subtle, disguising his true intention is that ultimately do not want their desks have nothing to do with that perola called Linux. Which we have prepared in this area, to assume positions of server administrators or coordinators of free software projects, we look stunned disbelief, as an underground movement is presenting anti Linux, do not know who commands this movement, but is inserted into all businesses as if someone was funding. And day after day recruiting supervisors and technicians who do not agree with the replacement of proprietary licenses, to form a mafia in charge of political sabotage migration. Definitely will remain for many years, a country Presidential, because only if the president again with music retrieval free software and bureaucrats tremble revolutionary government agencies, it could move forward and back on track. Although the Ministry of Science and Technology, together with the CNTI, is offering free technical training, coordinating seminars, conferences, etc.

, Directors of public administration only aligned if and only someone pushes back. It is a truly rare situation, they agree to free software, to please the central government, but are not willing to spend, we save with these free licenses, better equipment or the training of personnel, including some entities are returning decentralized migration from Linux to Windows again. We know that the strategy of the Ministry of Education and the Ministry of Science and Technology, for providing Linux and computers in primary schools, despite that may be the generation of relief, that is not going to be afraid of free software, however take many years for these children’s future technical developers and organizations to achieve set, for which in the meantime, we need to Emphasize and drives, the technology costs, the imposition of free software in public administration, setting aside so much flexibility, otherwise going back to buying proprietary licenses and conviction of the sovereignty and technological independence.
