Win8 Touchscreen shortage of
It is reported that, in the past few weeks, the traditional notebook computer manufacturer, Acer, Asus, Sony, HP and other companies have released many touch display laptop. Unfortunately, the touch display manufacturers usually intelligent machines and Tablet PC touch screen orders to give priority to production status, production will be used for the touch screen of the laptop placed behind. In fact, even the touch screen on the Tablet PC market also appeared inadequate supply.
This is why Windows laptop touch screen in short supply reasons, about 70% of the Windows 8 laptops touch screen shortfalls. Touch screen manufacturer models lack the experience to make the Windows 8 touch screen laptop production trapped in a more difficult position. The same situation also appears in the September and October, the laptop manufacturer's production process.
Touchscreen laptop demand in the next few quarters, will continue to increase, this trend only for laptop touch display also will continue to increase production, will it be possible to ease the touch screen panel on laptop inadequate supply situation.

Switching power supply notes
Switching power supply notes about selection and use
(1) The appropriate choice of input voltage specifications;
(2) Select the appropriate power. In order to make the growth of the power of life, the models suggested the use of more than 30% of the rated output power. For example, if the system requires a 100W power supply, it is recommended that the selection of greater than 130W output power rated models, and so on can effectively enhance the power of life.
(3) to consider the load characteristics. If the load is a motor, light bulb or capacitive load current when instant boot, should choose a suitable power supply in order to avoid overload. If the load the motor voltage shutdown intrusion should be considered.
(4) In addition, the need to consider the power of the working environment temperature, and the presence of additional auxiliary cooling equipment, excessive ambient temperature power derating output. Ring temperature output power derating curve
(5) Depending on the application required to select the functions: protection functions: over-voltage protection (OVP), over-temperature protection (OTP), overload protection (OLP).Application functions: signaling functions (normal power supply, power supply failure), remote control functionality, telemetry function, parallel functions. Special features: power factor correction (PFC), constant electrical (UPS)
(6) to select the desired line with safety regulations and electromagnetic compatibility (EMC) certification.
Note switching power supply
(1) Use the power, make sure that the input and output voltage specifications with the nominal value of the power used to match
(2) before turning on the power, check the input and output leads are connected correctly to avoid damage to the user equipment.
(3) Check the installation is solid, with or without contact, mounting screws and power board devices measuring shell input, output insulation resistance, in order to avoid electric shock
(4) in order to ensure the use of safety and reduce interference, please ensure reliable grounding ground
(5) multi-output power supply is generally divided into primary and secondary output, the main output characteristics superior to the auxiliary output, the output current of the main output of the general case. Generally requires every road in order to ensure the output load regulation and output dynamic indicators, with at least 10% of the load. Use side roads without the main road, the main road must add the appropriate dummy load. Refer to the specifications of the corresponding models.
(6) Note: The the Frequent power switch will affect their life.
(7) working environment, and the degree of load will affect their life.
Why power use will crash, reopen and again after shutdown?
Generally caused by the use of the power supply in the crash reason about both cases, the first load instantly overload caused by the overload protection, it is recommended to upgrade the power supply output power or modify the design of load; second temperature is too high, over temperature protection phenomenon. The above happens will power crashes into protection state conditions are removed before turning on power can be restored to normal.

Fridge Maintenance in Fall
After a summer of use, the fridge always an unpleasant smell, this refrigerator the cleaning and maintenance. Into the fall, the weather constantly cooler, reduce the number of families in the refrigerator operating at full capacity, working pressure, things need chilled in the refrigerator less, this is the best time for cleaning maintenance refrigerator, and refrigerator cleaning maintenance can extend the life of the refrigerator glow "youth" the autumn maintenance need to pay attention to what?
Usually bear in mind the four points of seasonal maintenance easier
1, should pay attention to store food
Busy day-to-day work, many of my friends often buy food fling go out into the refrigerator, which not only reduces the long food preservation, greatly reduce the nutritional value of fruits and vegetables, more importantly, refrigerator perhaps became the growth of bacteria 's paradise. We should pay attention to placing the food, what is it?
First, hot food should not be placed in the refrigerator, to wait for its cooling into the refrigerator needs the huge refrigeration to ensure that the temperature inside the hot food into the refrigerator must be in a cooling state for a long time, not only the costs of electricity and will damage the refrigerator. The second is the best food freezing chamber is divided into small portions, so not only frozen fast, and you avoid the moisture becomes frost. Finally, the food in the refrigerator, do not put too full, do not close the refrigerator left, right wall and the back wall, which is more conducive to the flow of cold air flow.
2, to reduce the number of refrigerator door
The refrigerator door too often, it will reduce the service life. Because every time you open the refrigerator door, there will be hot air to enter, when the internal temperature of the refrigerator will rise naturally speed the frosting, frost layer thickens, do not say we have cleaned up the task harder, more important is the cream layer is too thick, the increase in the workload of the compressor, abrasion along accelerated, while power consumption will gradually increase.
3, to prevent damage to the power cord
Some families are often the refrigerator on the corner of the kitchen, so cooking is very convenient to pick up vegetables and other foods. However, due to the fumes from the kitchen easy to siltation, and the corner is not easy to be cleaned, and the ventilation is not good, it is easy to cause the line to aging, is apt to cause leakage.
So refrigerator should select a cool, well-ventilated place to place because of the temperature increase of around 5 ℃, the internal necessary to increase electricity consumption by 25%. Secondly do not pile up too much debris around in the refrigerator to avoid heavy pressure on the power supply caused by power supply damage. Also, if necessary, the plug of the refrigerator should not arbitrarily uprooted, because of the mandatory power failure causes the current increases, easily burned refrigerator motor.
4, clean properly
In order to ensure the freshness of the food, to prevent the growth of bacteria, the cleaning of the refrigerator is particularly important. Cleaning the refrigerator in order to be safe, or should we cut off the power. After with a cloth dipped in clean water, undesirable way is to wash with water or cleaning with detergent, water and other refrigerator.
Need to clean the refrigerator in addition to housing and internal drawer can be removed to the outside, it's back to do the same cleanup. Here water can not be washed, the best way is to use tools like brush or duster to remove dust on the condenser and compressor to ensure proper heat dissipation. The final step is the freezer compartment defrost refrigerator defrost best dedicated shovel, avoid tool damage it.
Do not direct water flush door seals need to be carefully cleaned
Should be cleaning the refrigerator first disconnect the power, and then remove the food, and then remove the shelves, food boxes. The metal containers filled with hot water into the freezer, to use its heat to the inner wall of ice slowly melting. If water-cooled, and can be replaced several times. When the inner wall of the frost to melt almost gently with a plastic sheet ice is broken.
Available temperature and humidity scrub, wiping Bucharest small amount of neutral detergent such as detergent scrub, then wipe dry with a dry cloth. The door seals should be carefully cleaned, oil injection molded parts must wipe to prevent aging. Do not use water, detergents, acidic and alkaline detergent, soap, abrasive powder, gasoline, alcohol and benzene the organic solvents scrub or scrub. Not to direct water to rinse the refrigerator to prevent electrical insulation capability of reducing and rust.
Refrigerators on the back of the condenser is easy to accumulate dust, affect the heat, so at least every six months to use a duster or vacuum once; catchment tray cleaned once monthly to bring it up. Defrost melt water evaporation is not easy, if dirty will produce odor.
After cleaning, you want to check whether the power plug and power cord damage. The power plug is firmly plugged in, check the thermal controller is set in the correct position. The refrigerator is not a long time, unplug it, the refrigerator is clean and dry internal, and the refrigerator is placed in a dry and well-ventilated place.
If you usually pay attention to maintenance, may be a week to wipe the surface of the refrigerator again. If there is grease or dust, available warm water to clean. The refrigerator wall wipe with glycerol, the formation of a thin layer of protective film, even if the the stained milk or food residue, can also be very easily with a rag to wipe off.
Understand the five major taboo health using the refrigerator
The refrigerator should keep in mind the five major taboo, healthy refrigerator.
1, the food should not be too full
Refrigerator to store food should not be too crowded, it is best left some gaps, so as to normally convection of air in the refrigerator, in order to lighten the load of the unit. Huddled together and too much food, and also very easily lead to cross-infection of the bacteria in food, leading to all kinds of discomfort, as well as a variety of diseases to the human body.
2 meat processing
Buy some fish, pork, beef and other foods, it is best able to carry out some of the corresponding processing, then put in the refrigerator. Like the best fresh fish, meat and other foods are first encapsulated with a plastic bag, and then stored in the freezer. Vegetables, fruits, should the appearance of water, dry, then placed in the refrigerator at the bottom, above zero temperature storage is appropriate.
Do not freeze bottled drinks
For the appearance of food packaging, such as various types of drinks, milk and other foods, it is best not in the freezer to prevent the cracking bottles. The best position to store the freezer or a doorstop, the best temperature to maintain the temperature at about 4 ℃ storage is best.
Refused to hot food
Some people like to just pan of food on the very spot in the fridge to cool, hope will be able to eat tasty food in a short period of time, but these too hot food if put into operation as soon as possible with a refrigerator, likely less short refrigerator life.
5, both raw and cooked food can not be put together
Raw food and cooked its storage time and temperature requirements have different requirements, and generally are present in the raw food with various parasites and bacteria, and cooked together contamination of cooked food. At the same time do not put food directly on the surface of the evaporator, to be on the vessels, so as not to freeze in the evaporator, and inconvenience to remove.
