How to work SMPS ? ( हिन्दी)
Web: www.arieslaptoptraining.com Mail : [email protected] A switched-mode power supply (switching-mode power supply, switch-mode power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a source, like mains power, to a load, such as a personal computer, while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in the high dissipation transitions, which minimizes wasted energy. Ideally, a switched-mode power supply dissipates no power. Voltage regulation is achieved by varying the ratio of on-to-off time. In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. This higher power conversion efficiency is an important advantage of a switched-mode power supply. Switched-mode power supplies may also be substantially smaller and lighter than a linear supply due to the smaller transformer size and weight.

How to check MOSFET with multimeter  (हिन्दी)
www.arieslaptop.in [email protected] MOSFET is a field-effect transistor in which there is a thin layer of silicon oxide between the gate and the channel. MOSFET used in Desktop and Laptop motherboards there are two different types of MOSFET N-Channel MOSFET. P-Channel MOSFET. N-Channel MOSFET Used in Desktop motherboards while in Laptops (motherboard) both N-Channel and P-Channel MOSFET are used. Ok! Enough talk about introducing MOSFET lets Do the testing Process and see which MOSFET is working one and which one is non-working. During testing I will show you which one is P-Channel and which one is N-Channel MOSFET. To test a MOSFET we will need a Multimeter and some working and non-working MOSFET. Mulitimeter-with-MOSFET Ok as we can see MOSFET consist of 3(three) pins 1) Gate 2) Drain 3) Source Gate-Drain-Source-MOSFET Now set your Multimeter to (Continuity Beeper) and Black Probe to Common Ground and Red Probe to Ohms(Everything but Ammeter). Touch Both Red Probe and Black Probe and if your hear a beep sound than you are ready for testing MOSFET. First we will check if this MOSFET is N-Channel or P-Channel. N-Channel MOSFET: Connect Black Probe to the Drain and Red Probe to the Source of MOSFET and if you get any Value on screen of Multimeter than this MOSFET is N-Channel MOSFET.If you did not get any value than better try second one. P-Channel MOSFET: Connect Red Probe to Drain and Black Probe to Source and if you get any Value than its P-Channel MOSFET. So now we know how to find P-Channel and N-Channel MOSFET so its time to test if its in working condition or not. N-channel Working MOSFET: Now Pick a N-channel MOSFET and connect Black Probe to Drain and Red Probe to Gate if you don’t see any value than its working MOSFET.If you see some Value than its a (short MOSFET, a leaked MOSFET or not a MOSFET at all). As its working MOSFET lets charge this MOSFET, connect Black Probe to Drain and touch Red Probe for few seconds to Gate and than Touch Red Probe To Source while Black Probe should stay Connected to Drain and you will here a beep which shows that your MOSFET is charged and in working condition.Remember to do the same test again you have to release to charge from MOSFET you can do this by Holding a MOSFET for few seconds between you fingers or just connect Black Probe to all three Pins at same time. P-Channel Working MOSFET: If you have a P-Channel MOSFET than connect Red Probe to Drain and Black Probe to Gate and if you don’t see any value than its a working P-Channel MOSFET but if you see some value than probably this MOSFET is Short or leaked MOSFET. To charge a working P-Channel MOSFET connect Red Probe to the Drain and touch Black Probe to Gate for few seconds and bring back the Black Probe to Source and you will hear a beep sound which means your P-Channel MOSFET is charged and good to go.

Tips to take care of your laptop: Laptop cleanliness: -Keep liquids away from your computer: Liquids can damage or short internal components, corrupt data and make keys stick or not function. -Keep food away from your computer: Crumbs can damage the keys preventing them from depressing totally, invite small bugs, damage circuitry and make the laptop look dirty. -Have clean hands: Dirt and oils from your fingers and wrists can eat away from the protective finish on the laptop, keyboard and track pad. -Use an old clean toothbrush to clean parts of your computer: Cleaning around the keys on the keyboard, exhaust fans and around the bezel of the screen will help promote airflow and reduce heat buildup inside the laptop. LCD Monitor: -Prevent damage to the monitor: Make sure there are no obstructions (paper clips, pens or pencils, cats, motorcycles, etc.) on your keyboard when you are shutting the lid. Items like these can dent, scratch or even crack the screen. -Close the lid properly: Close the lid gently and hold from the middle of the screen. Closing the lid using only one edge causes extra pressure on the hinges which over time will crack and break them. -Hold your laptop by the base: Lifting and holding the laptop by the display creates unneeded pressure on the hinges. This action may direct pressure to the LCD and deform or crack the screen itself. -Be aware of what you put on top of the laptop: Placing heavy items on the laptop (open or close) can cause serious damage to the LCD, hinges and chassis. Placing heavy items on your laptop can also squish the optical drive (CD-ROM) and if there is a disk in the drive, shatter that too. Transport: -Do not expose your laptop to rapid temperature changes: Large temperature fluctuations can cause major damage to your laptop. The metal platters inside the hard disk can expand and contract rapidly. If the metal platters are being accessed at the time, they may even crack causing partial, if not total, data loss. The temperature change can also form condensation within the laptop and short internal components. -Do not leave your laptop in your car: Leaving your laptop in the car will expose it too severe tempertures and possibly further damage. Even in a laptop bag, leaving a laptop in the car is an inviting target to a thief. -Use a laptop bag: Laptop bags reduce the chance of accidental drops or bumps to the laptop. If using another bag like a book bag, consider a laptop sleeve. A sleeve is not as protective as a bag but it will reduce damage and scratches too. -Use a laptop bag that fits: Make sure your bag is large enough to fit your laptop but still remain snug. A properly fitted bag will help prevent damage to your laptop during transport and is a good place to store the power adapter and other laptop accessories. Power: -Do not pull on the power cord: Pulling on the power cord can damage the cord, socket, and plug. Instead, grab the actual plug and disconnect from the wall socket. -Do not roll over the power cord with your chair: Rolling over the power cord with your chair can lead to a short and further damage to the power cord, power supply and laptop. -Power Conservation: If not using your laptop for more than two hours, shut it down. The power consumption of the laptop within those two hours is far greater than that required to power on the laptop. -Battery Maintenance: Leaving a laptop plugged in after the battery is fully charged will reduce the overall lifetime of the battery.

Input/output controllers receive input and output requests from the central processor, and then send device-specific control signals to the device they control. They also manage the data flow to and from the device. This frees the central processor from involvment with the details of controlling each device. I/O controllers are needed only for those I/O devices that are part of the system. Website: www.arieslaptop.in Email : [email protected]

The voltage available from a wall outlet is a poorly regulated AC ranged worldwide from 90V to 240V, while most electronic circuits require a well stabilized low-voltage DC. That's why all electronic equipment needs some form of power conversion. A PC power supply unit (PSU) is an internal device that converts an input AC to a set of regulated DC voltages needed by personal computer. In the process it also provides primary to secondary safety isolation. Since the introduction of IBM PC/XT, there have been about a dozen different PC types. They differ by their structure, form factors, connectors and volt/amp ratings. The output rating of a modern computer PSU ranges anywhere from 185 W to several kilowatt. The units over 400W are used mainly for servers, industrial PCs and to supply the desktops with high-end video applications Mail: [email protected] Web: www.arieslaptop.in

Motherboard diagnostic cards ( PCI POST cards) are electronic devices that fit into the PCI slots, can analyze hardware issues and BIOS faults. These troubleshooting tools can usually find problems with the BIOS, video, CPU, hard drive controllers among other components. A computer system has a number of failure points and while the cause of some issues will be quite obvious, at other times faults can be very difficult to find. Motherboard diagnostic cards can help technicians to quickly pinpoint the cause of system errors or hardware faults. This saves on time that would otherwise be spent in the trial and error process, and prevents waste of money purchasing the wrong solution.

Learn Laptop & Desktop motherboard chip & bga level in 20 days course Please visit our website for more information www.arieslaptoptraining.com Mail: [email protected] What are POST Codes? "POST" stands for Power On Self Test. When the BIOS starts to run, it does a Self Test of the components on the motherboard, and in some cases, boards that are plugged into the various slots. It goes through several steps of checking, testing and initializing the hardware components. Before entering each step, the BIOS writes a 2 digit identifying code to an external address. This code is commonly referred to as a POST code. The meaning of the codes varies widely. Most computer manufacturers use a BIOS supplied by a third party, the most common are Phoenix and AMI, but there are many others. The codes also vary depending on the motherboard and the manufacturer's requirements. These codes are useful during the manufacturing process to help identify problems. To the consumer, they are useful in cases where the system won't boot up and the video screen does not work, or if you are attempting to make modifications. If the BIOS detects a problem, it will stop on the problem, and the last code that was output will indicate what the failure is. In order to see the codes being generated by your BIOS, you will need a Post Code Master Display card, which plugs into your PC and displays these codes as the BIOS performs its tests. There are versions available for both ISA and PCI motherboard slots. The card displays HEX digits which consist of the numbers 0-9 and the letters A-F. The letters B and D are displayed as lower case (b & d).

VRM: Voltage regulator module, this term refers to anything from a linear regulator to a synchronous multiphase buck converter, which is a switch mode power supply, which is what your motherboard’s CPU VRM is. People also call the VRM the PWM, which isn’t correct, PWM refers to a modulation scheme or a chip, not the entire circuit, however since PWM has a catchy ring to it people still refer to the VRM as the PWM. Some others may also call the VRM a VR or a VRC(voltage regulator circuit). PWM: Pulse Width Modulation or Modulator, this is a scheme where phases are turned on and off in a pulse like manner, it can also refer to the control chip of the VRM. The PWM control chip does everything from turn on phases to monitoring different characteristics of the VRM, the PWM is the only part of a VRM that could be considered digital in nature, however it is possible to design the PWM with analog mechanisms(which is quite easy and popular)
