, the battery voltage is not equal to the charging voltage at the time of charging. In support of the high-pass Quickcharge protocol models, often take is low current fast charge, such as QC2.0 standard 9v1.2a and 12v1a, at this time only to see the charging current can not determine whether the device is high-pressure fast charge, can not judge whether the charger is really supporting the QC protocol.Voltage and current information storage location:/SYS/CLASS/POWER_SUPPLY/USBThe Voltage_max sup

Liquid crystal display with thin fuselage, save space; do not produce high temperature, low radiation, good health, the screen is not to hurt the advantages of the eye is now widely used, that everyone on the life of the liquid crystal display is not understand how long, the following small series to introduce the life of the LCD display is how long, hope to help everyone. The following is an introduction to how long the life of a liquid crystal display is. 1, about 50,000 hours, m

this: when the machine is started, will u8expstep = 255, s16exptolerance = 50, this is because the image appears faster, if the setting is small, the image will be from dark to light about 5 seconds (here to see personal needs). When the machine executes to about 5 seconds, we then set the value to U8expstep = 16, S16exptolerance =10,u8expstep is set to 16 because preventing changes in the light source will cause the image to quickly effect (flash flash). The s16exptolerance set to 10 is set fo

, I really hope that Sony only 3 products AH.The traditional idea is that enterprises can provide more product choices. However, each product is bound to wear down the enterprise resources (time, manpower, money), Apple's choice of slow, small number of products can attack the market share rate (ipod about 70% of the MP3 Walkman).Another layer of focus for jobs is to say "no". When every manufacturer launches a product that offers the same specs, Apple has the courage and confidence to make it d

); Keybd_event (vk_off, 0, keyeventf_silent │ keyeventf_keyup, 0 ); The two keybd_event calls simulate the press and release power button. The virtual key value of the power button is vk_off. Executing the preceding two lines of code suspends the system. Because the virtual key code is executed by GWES, the two functions may be in a certain state before the system is suspended, the image is the same as that of the actually pressed button ).

Only because these products are based on the UNIX architecture, but also high prices, so there is no large-scale access to pervasive applications. Later in 2004, AMD and Intel unveiled their dual-core plans, and for the first time since 2005, they have been supplying dual-core products. Of course, the two companies have launched dual-core processors dazzling-including AMD launched dual-core Opteron server chip and Athlon
