Sample teach you buy a laptop anti-JS six strokes

Whether rich or the common people under heaven, each person had to spend every human consumption does not deceived, 315 step-by-step approximation, IBM ThinkPad R51 battery  IBM ThinkPad R52 battery but the trick JS not enough to disappear completely, for the purchase of laptop users, the endless hoax is that we simply can not avoid the ordinary users, because we are not expert in mobile, often purchased with a laptop JS enthusiasm was obtained fraudulently , losing everything for laptops have become for the addition to the existing cottage Han counterfeit or not, and tips almost turned around and price performance, alter, today we speak of struggle against Zeneng sample furu -JS, Bang Bang’s apply the common people.

Buy Laptop Anti JS-1 features: Verify the external appearance of the books Though there is no technical content of some, but make sure the appearance is very necessary, because now, three packs of France where the appearance of a very vague definition of the problem, even if they retreat, JS usually steal consumer after the result of the purchase, be sure to see if there are shells Diaoqi, wear The hinge cracked and loose, if there are problems then the firm called JS-for.

Buy Laptop Anti-JS 2 times: check the serial number of the serial number is usually in these places: the body, battery, external boxes, manuals, certificates and other parts of the UNPROFOR. However, to verify if it had been amended and was displayed off the stage. Some books at boot time, entered the BIOS of the laptop, make sure that the BIOS serial number and serial number of the fuselage are the same. If there is a discrepancy, this model does not absolutely, the solution is a single word: “Change!”

Buy Laptop Anti-JS 3 shots: Test the LCD screen special inspection was to determine if the dead pixels, you can use the software NOKIATEST check and give you a LCD screen can indirectly test the time response software - DisplayX. It can also detect if the dead pixel LCD screen, you can also find in the area of travel does not dragging the shadow of his time is appropriate for your books LCD delay time on the screen. 371785-001 417066-001

Buy Laptop Anti-JS 4 stroke: test processor that many consumers think that the processor is more difficult to begin by deception JS components, but the fact that some of the JS is the use of consumer psychology desperate to make history in the BIOS above, the transformer low frequency transformer into a high frequency of misleading the operating system, but also for consumers of a Mongolian. They must use the latest CPU-Z test.

Buy Laptop Anti-JS 5 traits: detecting the video card can Everestpro software, 3DMark01 to check if your graphics card on the books shrink. Each card in the 3DMark01 score in the circumstances, the user may advance on-line surveys. Note that if you use the battery test, the latest test scores from scores significantly lower than normal.

Buy Laptop Anti-JS 6 features: Battery test battery for the laptop is more important, through a post-test or Batterymon BIOS, if found to load more than 3 times then the battery is used, the user can ask the dealer to replace. And watch to see the ability to load “and” full load capacity in these two columns of data are the same.

PS: Finally, I draw attention to the controls provided by donations from traders, confirmed it is correct, then it could take leave Jiaoqian. It will also help develop vote!! Latitude D610 battery Latitude D620 battery

Without battery-operated wireless transceiver device will come out

United Microelectronics Research Center (IMEC) at the recent International Solid State Circuits Conference reported a power consumption of only 51 micro-watt 2.4GHz (Ji Hezi) / 915 MHz (megahertz) since the alarm receiver. The minutes of low-power developed without Sony VGP-BPS8 Sony VGP-BPS8A battery or can be automatically capture energy opens the door to devices transceiver wireless technology can be widely used in the identification of long range radio frequency (RFID) and logistics, smart buildings and medical services used by the wireless sensor node.

Currently, the battery system of wireless communication in wireless devices do not send or receive data consumes much power, which means that most of the time, the Bluetooth phone or a wireless LAN when you do not work and also the battery access to energy. IMEC developed with ultra-low power consumption and fast response time of the receiver clock can be compared with the equipment transceiver traditional to send or receive data when you need to change. GD761 KD476

R & D based on double sampling of new wireless transmitter architecture can overcome the 1 / f noise, 1 / f noise will affect the majority of low-speed (10Kbps to 100kbps) devices transceiver wireless. Therefore, obtaining the same performance as the traditional principle that the device transceiver high data rates of devices has a higher budget power. Double sampling technique, 1 / f noise can be reduced, so that the receiver sensitivity can change with the data rate to increase proportionately. TD347 C1295

Self-clock receiver chip using 90 nanometer digital CMOS technology, the chip area of about 0.36 mm2. Measurements show, 915MHz 100kbps receptors (OOK) modulation of the sensitivity of-75dBm (signal to noise ratio greater than 12dB). When the data rate of 10Kbps and filter by business soundtrack, the sensitivity may increase 5dB. 2.4GHz receiver and 100kbps data rate of 10Kbps cases, the sensitivity of-64dBm, respectively, and-69dBm. PC764 Y9943

The researchers reported that research in autonomous systems, wireless sensor, the research objective is to develop energy can be made to the environment, instead of using cell systems of wireless sensors. For the digital signal processor, radios transceiver and sensors, power budget of the system of only 100 microwatts. Only 51 micro-watts of ultra-low-transceiver power wireless devices successfully developed towards achieving this goal has taken a major step, which is as long-range RFID, smart lighting, sensor tags and other applications not the battery, opening the door. 371785-001 417066-001

Battery welding and assembly

1. Oxygen - the use of acetylene

Oxygen - acetylene welding is a welding bus, bridge tools, welding quality is good or bad, the good relationship between the degree of operation and more competence, Sony VGP-BPS10A Sony VGP-BPS10A/B the operator must spare no practice continuously improve the professional level . Operation NOTE:

Depending on the size of the head of the selection of welding Welding Joint Model:

Note that the distance between the torch and welding, welding, welding position clear, welding almost bit.

Torchlight, the first open acetylene gas acetylene, then opened fire when the oxygen closed when the welding torch, first oxygen, then the arrival of acetylene gas.

Work, attention to the time off the gas valve of the oxygen and acetylene.

2. The use of iron

Soldering iron is a great column and leads to welding parts (terminal) is the only tool for electric soldering iron and oxygen - acetylene welding with different welding techniques. Welding, sheet welding sets in a column first time, the welding wire (including rosin) solder pieces on top, electric soldering iron melting solder wire first, followed by division and then merging , melting polar column and the solder will melt films together. Welding must pay attention to;

Always keep the iron with a layer of tin, such as the layer of tin off, will tip the net with the file immediately CuO fusion welding wire on top. Inspiron 5150 battery Inspiron 700m battery

Tip temperature to appropriate high temperature soldering iron, when the layer of tin is easy to take the head temperature is low false welding or welding Yi is not strong. Regulate the temperature of the TIP is a fixed tip of the screw loose screw, insert the tip of the soldering iron to change the location of the interior elevation of temperature outwards, the temperature drop.

Choose the appropriate power of the electric iron (usually in the 200-500W or so). To ensure there is enough heat to absorb technology.

Beautifully rosin flux, can not use a corrosive flux.

All welding is not a complicated theory to talk about mainly by the operator through the expert hands slowly. Workers Stone attention to culture in the production of a number of skilled workers to improve the stability of product quality is very important.

3. Manual Welding description framework

Frame welding is the positive plate (or the negative) with lead solder (bus composition) and the 371785-001 417066-001 Polish and buses welded together tools. Welding tools usually oxygen - acetylene welding torch.
