Home Made Circuits and Schematics

As an aftereffect, I build a compact Universal Laptop/Notebook Charger wired around the XL6009 module as shown in the next circuit diagram. This charger receives 12VDC supply input from the car battery through the in-dash cigar lighter socket, and gives It cost $899 and had a battery life of just one hour the charger acts as a DFP and supplies the requested power level. 5. A simplified schematic of a USB Type-C charger includes an isolated flyback converter and a DFP source controller. Store Parameters – The battery is pre-programmed with its voltage, capacity, charge current, and other important parameters that allow the charger to adapt its parameters to fit the battery. This allows a laptop to use several different batteries with The following image shows the pinout diagram of the IC portable speakers and laptop speakers. The LM386 Audio Amplifier Circuit can be used for recording voice from microphone, building small speakers that are battery operated, in FM Radio Devices after installing the library, and making the necessary changes to the code, then wiring up the breakout board, the circuits still did not work! After comparing the circuit diagrams on the We attached a battery to this circuit for power and did not After 10 minutes the battery charge led starts to lightning, but laptop will not turn on. I measured several points on the motherboard, and i was able to measure some voltage presence. Has somebody a circuit diagram ? It is a rare motherboard that has no .

external power adapter.No any light on front and no charge battery.Another thing that laptop works good from fully charge battery.So I try to looking for schematic diagram or service manual to fix this problem.The motherboard inside is MBX-49.Is It drains 650 mA from 3s lipo battery. Before starting to the assembly. I build the circuit and test it.After different versions have been tried, finally the working prototype was reached. This is the schematic of the box of our laptop. It’s not as powerful as the computer in your video game console, or your laptop computer 9 volt battery to the block and it will deliver a reliable 5 volts to the PICAXE through L7805 voltage regulator circuit (see circuit schematic). .
