principle, have an impact on device lifetime, but according to today's point of view, the reliability of electronic components has been quite good, as long as the design range, rarely a problem, life will not be short life than books, so this is not the main problem. More important issue may be the books of the data security, a sudden stop working for the automatic protection of the computer is a terrible thing, especially a lot of friends without the battery. Sometimes a reboot the computer somehow and relevant. For the first wife of the power supply, the manufacturers know what kind of access is a load, so you can easily calculate the nominal power supply voltage and nominal current, the nominal voltage power supply should meet the following two conditions, first when the nominal maximum current output voltage minus the power supply itself should be larger than the load required voltage drop of 95%, the second is the smallest when the current output voltage minus the power supply itself, the design should be less than the required load voltage drop of 105 %. However, if the adapter using a non-original equipment, such as general purpose transformers and the like, the problem can not be seriously considered, this is from the electrical parameters of the user can only think of ways to be compatible as far as possible, but the resistance is different for each adapter , the nominal voltage of the allowable error may be different, under the nominal current output voltage range of the definition may be different, and even output ripple factor is not small enough not necessarily, if not carefully measured the output power with the relationship between the output voltage, in principle, there is a certain risk, but this risk is small, because if you choose to supply enough current nominal resistance does not appear the problem is too large, the ripple coefficient can also be stable within books pressure to reduce, so I said, first wife of the power

supply is usually better than non-first wife. This is the first wife and the general power supply difference. Command of the situation. Then dust on the need to be handled. In general, the mechanical mouse just need to clean up the "body" in the rolling ball and roll axis can be.

Here to talk about why the first wife of the power supply is usually better than non-first wife. I want to say first wife's power theory is relatively better, in fact, may not feel different. Allowable load is usually a safe range of input voltage, such as the nominal value plus or minus 5%, one example is that many 2.5-inch hard drive 5v input requirement is plus or minus 5%. Notebook, too, if the input voltage is too large or too small will result in protection circuit action, in order to stop work. But the action in the protection of the circuit before the books have been biased internal regulator circuit working upper or lower limit, in principle, have an impact on device lifetime, but according to today's point of view, the reliability of electronic components has been quite good, as long as the design range, rarely a problem, life will not be short life than books, so this is not the main problem.
