Open your laptop''s case using your specific laptop''s motherboard replacement guide, which can be found on your specific laptop''s device page. Using a flashlight, visually inspect all of the capacitors on the motherboard. Visual symptoms of failed capacitors include the following: Bulging or cracking of the capacitor''s top vent,
Capacitors are found in many devices and can be hazardous. Especially high voltage capacitors should be treated with extreme caution. You will encounter them in audio amplifiers, microwaves, televisions, switched-mode power supplies, guitar tube amps and HVAC equipment, amongst others. With the right tool it is easy to discharge capacitors safely.
Capacitors are incredibly simple in their concept but the details, the way they work with DC and AC signals, and their imperfections provide an unbelievably diverse amount of applications and considerations. Dozens of tutorials can be written about the different capacitor uses and we''ll see how many of them we''re able to put together. If ...

This month repair article is about how you can make a hand tool to discharge the big SMPS filter capacitor using a simple DIL extract tool, two 470 Ohms x 7W resistors, two probe tips and some shrinkable tube. The resistors are connected in series and you need to cover it with shrinkable tubes.
Doing some simple experiments, including making and measuring your own capacitor, will help you better understand the phenomenon of capacitance. In this lab, you will use a commercially …
A PHY-102 student at Mulungushi University wants to make a simple 10 𝑛𝐹 capacitor for tuning her crystal radio, using two sheets of aluminum foil as plates, with a few sheets of paper between them as a dielectric. The paper has a dielectric constant of 3.0, and the thickness of one sheet of it is 0.20 mm. ...
Here in this blog I explain something about capacitors and teach you to make a simple capacitor in your home. So, first we discuss about capacitors and then about the DIY capacitor making. Capacitor. Basically what is a capacitor? It is a basic electronic component which stores electrical energy. It is a passive device. It has only two leads.
