Solve : Testing motherboard with a volt meter? |
|
Answer» Can anyone point me into the right direction to find out how to test a motherboard with a volt meter.I personally think the short answer to this question is "You cannot do this. A motherboard is not a toaster. You could test the PSU with a voltmeter". The long answer would be "If you are a skilled and experienced technician who is very familiar with the motherboard model and knows what voltages to expect in what locations and also knows what it means if they are absent or different from what you expected then maybe - maybe - you could get some information from those voltages". But if you were, you would not be asking this question. However, you ASKED to be pointed in the right direction, so you will find some information at the link below which might help you. isn't a multimeter a different tool from a Voltmeter? A voltmeter just measures voltage, and would be quite limited for troubleshooting a motherboard. A multimeter or "multi range test meter" measures a number of selectable things - usually voltage, current and RESISTANCE, but often other things such as frequency, capacitance, inductance, transistor gain, temperature, and some even can work as digital oscilloscopes. Quote some even can work as digital oscilloscopesWhich would be a better choice. Quote from: BC_Programmer on May 20, 2011, 07:07:21 AM isn't a multimeter a different tool from a Voltmeter? Sorry I should have said Multimeter not volt meter OjasMost DIRECT is you can not test a motherboard with a Multimeter. However, the multimeter can be used to identify a problem with the power supply, which may be the reason the motherboard does not respond. Do a Google on: How to test motherboard The general answer is to LOOK for obvious things: 1. Smoke or the odor f something burnt. 2. Chared components. 3. Bulging or bust capacitors. 4. Parts damaged by rodents. (Not a joke.) Or any visible clue that something is not right. Unless you are in a rock band on stage, smoke is usually a clue that something is wrong.Quote from: rthompson80819 on May 21, 2011, 02:14:44 PM Unless you are in a rock band on stage, smoke is usually a clue that something is wrong. Electronic components have smoke inserted at the time of manufacture; it is essential for their proper functioning. If it ever gets let out, the component is usually ruined forever. |
