Q:I have found the event viewer in the boot event, ask what should be done next Ask God ...: Open the event viewer and look for an icon with no empties Click "Start → Run", enter eventvwr, click "OK", you can open the event viewer. Right click on the "application" "security" "system" menu to clear!

Q:I produced the power supply is output 12V and 5V two groups. Current is 2A. Will the normal aging time is how much the load should be connected to the number of normal. Please advise experts. Thank you so here.: The initial trial production can be 24 hours of aging, and take 10% of which for a long time aging (at least half a month) to ensure quality. Into the first five batches of 100% load aging 40 minutes, if no problem and then you can use 80% or 100% load aging 25-30 minutes. General power plants are the same operation. Aging conditions: Ambient temperature: 35 degrees Celsius Aging load: 80% of total power

Q:Press the TV switch to a long time to start the TV, and not necessarily how long, maybe 10 minutes, maybe one day do not get up, when the frequency is also started, is to start - off - start - off .... Until the start of stability so far, what is wrong with this, ah, how much money to repair?: This problem is generally in the cold when the weather appears, commonly known as preheating phenomenon, in fact, is the capacitor failure. The biggest possibility is the power and motherboard, the term called cold start point does not shine. Capacitor temperature is low when the voltage power is not enough, not enough to support the boot, power on a capacitor temperature will return to normal to boot. This is the case of capacitive failure. First replace the power test, if the problem can still be determined to be the motherboard capacitor problem. I am a so-called work package 600W, with a few days of cold weather on the emergence of this situation, and later changed the TT500A problem to solve. The above is the computer often problems, I do not know the TV, but you can refer to the next, if only the capacitor problem, maintenance costs are relatively low. ? The answer was adopted by the questioner

Q:If there are three lights can use a microcomputer when the control switch to the different time: You want to have a control three way. You can analyze it into three ways. Install a switch on each way. So that you go to the artificial cut off the exact time to let a microcomputer control switch to control

Q:For example, a week, I play every day, every day switch machine? Can you sleep all the time? If you can sleep, how long is the best sleep?: No relationship, when not on the shutdown, so as to extend the life of the hardware. Long boot is not good! Sleep is in the system before the shutdown, the memory of the file backup to the hard disk, and then you boot the next time, you can directly read the last backup in the hard disk image file to memory, so as to achieve rapid response. But the disadvantage is that sleep is sometimes difficult to recover!

Q:Millet phone how to set the switch machine time?: Shutdown to use third-party software, boot set silent alarm clock, shut down after the time to automatically boot

Q:Time control switch for a shortest time to add time relay to reduce the time to a few seconds how to increase: Plus a ST3P power delay time relay, the time relay coil and relay two groups of public point connection, often close to you want to control the equipment such as bell, the control switch output power supply relay coil, so you can

Q:Is there a software that can record the time on the computer?: C: If you still feel too much trouble, then had to use nirvana. Type "C: WINDOWS schedlgu.txt" in "Run" in the "Start" menu. In the open schedlgu.txt file, "Task Scheduler Service" has been started and the "Task Scheduler Service" has been exited In the time, respectively, corresponding to the boot and shutdown time, is not it convenient? Every day for the record is not difficult. D: If you want every time the switch machine can be clearly recorded, it can be "script + batch" approach. But you have to hands-on, we use the "script + batch" approach to achieve. Simply add two batch-time batch commands on the power-on, shutdown script, and let them start or close the recording time with the system into the C: aaa.txt file. First create two new text documents, respectively, used to record the boot and shutdown information, enter the following command, and then save as ". Bat" file on it. Where the boot batch (start.bat) is as follows:

Q:Other brands are what, please specific models have the best manual In addition, I do not understand why the design of the dual power supply conversion time so high? What are the devices or devices that require 0.5 seconds? Thank you to answer the perfect set points: Change the transition period? Similar to the strict requirements of the same period is the grid, requiring phase sequence, voltage, frequency are the same. UPS and dual power switch is not a concept, like your phone to change the use of charging, there is no power switch problem, because they are battery-powered, nothing more than the battery at the same time whether the charge in the charge. More detailed on the power switch problem I can not reply, I was engaged in industrial control -_- !!! But from the actual use of view, in fact, you still mention the point of the most critical, which devices and equipment on the dual power supply switching have different needs, from my contact, such as the Pudong Airport runway lights double power, oil machine Three-way power supply) switching time requirements are concerned, is not more than 15 seconds. Other more stringent requirements, really did not encounter.

Q:What is the response time of the switch?: The time required to switch from the on state to the off state, or from the off state to the on state, the time between the two is not the same, and generally take the average value
