![]() GPU is a graphical processing unit, which handles computation for 2D/3D graphics applications. It is measured in Megahertz (MHz) or Gigahertz (GHz). The frequency of the processor describes its clock rate in cycles per second. They increase the performance of the device allowing the execution of multiple instructions in parallel. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. If the CPU does not find the data needed in L2, it proceeds to look for them in the 元 cache memory (if there is such) or in the RAM.Ī CPU core is the processor unit, which executes software instructions. Just like L1, it is much faster than the system memory (RAM). ![]() The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. In some processors the search in L1 and L2 is simultaneous. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory. The L1 (level 1) cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. Information about the set of instructions the processor can execute. The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. 64-bit CPUs provide better performance than 32-bit ones, which on their part perform better than 16-bit processors. The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. Its main function is to interpret and execute instructions contained in software applications. The value in nanometers represents half the distance between elements that make up the CPU.ĬPU is the Central Processing Unit or the processor of a mobile device. Information about the process technology used in manufacturing the chip. The SoC integrates different hardware components such as the CPU, GPU, memory, peripherals, interfaces, etc., as well as software for their functioning. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. Materials used in the fabrication of the device's body. Information about the colors, in which the device is available in the market. Applies for devices in the form of a rectangular parallelepiped. Information about the weight of the device in different measurement units.Įstimated volume of the device, calculated from the dimensions provided by the manufacturer. Information about the thickness/depth of the device in different measurement units. the vertical side of the device when it is used in its standard orientation. the horizontal side of the device when it is used in its standard orientation. Body materials, available colors, certifications. They have the necessary experience and tools to open your phone and change the motherboard of your LG K7.Design Information about the dimensions and weight of the device, shown in different measurement units. You need to approach your retailer or go to an LG authorized service station for your phone and have a professional handle this issue. However, this is a complicated process and should not be performed by you. You need to replace the motherboard of your LG K7. If you find that none of the problems are responsible for your phone for not powering up, then the problem lies in the motherboard. Try a different outlet to test whether the connection is stable. When there is no proper flow in the current the phone will not be charged properly. A damaged electric outlet could also be the cause of the problem.If the sound does come then the sound system of the LG K7 is problematic. Push the power button of the phone while keeping it close to your ears and try to listen if there is a beep sound.If your battery charger is faulty, then it may cause problems in your phone. ![]() While you are checking the battery also go through the charger. Make sure to double check the battery and if required replace it.
