the main issue is on the connectors therefore there are characteristics ,,what is it?????????

Connectors of...what?  You need to give a general field, here.

I think you;re on target. It's probably the cable. Make sure the cable is shielded. and the shield is only connected at one end.

Hi,\n\nHere is a pic with many laptop connections.\nAll are named on the pic.

Inductance is the "definite answer" that I was given 30 years ago. I don't suppose that my confirmation is any better than yours, but it's a vote anyway.

It is a number of things it could be.  Tie rod ends, idler arm, pitman arm, gear box.  Best to have a auto tech check it out.

The most important one are the glitches that can occur when there are differences in the propogation delay between gates.\nIt is possible to design logic circuits so that these glitches have no effect - can't remember what the technique is called, but involves overlapping fields in the Karnaugh maps.\n\nAnother characteristic to consider is the total propogation delay of the combinational circuit. The more logic gates you have in the path, the longer the delay

Look for connections: causes and effects.\n\nGOOD Question!

See Resources below\n\n***WARNING: When working with power supplies, be sure to read up on power supply safety.  It is quite dangerous (possibly FATAL) to work on power supplies if you do NOT have knowledge about how to SAFELY work with power supplies***

i have fixed those connectors before.\nits not real easy to get to one of those.\none must take everthing off the motherboard, then, pull the motherboard.\nthe connector will need to be reseated and soldered back on.\nputting a laptop back together can be hair raising

There are pros and cons.

Sounds like static electricty, which tends to develop in windy dry conditions.  Check it out.

The four pin connector you described is probably connecting to a hard drive or a CD/DVD drive.  I have seen a power supply fail to power on when connected to a bad hard drive, or CD drive.  Try replacing whichever component is causing the problem.

Maybe because it is depicting Current flow NOT Electron flow??

I believe there are issues in that department...

Current PC power supplies (I'm assuming a desktop or tower style power supply here) have several types of wiring coming out of them. I'll list them with comments. \n\n--Flat 4-pin inline wite plastic connectors, lots of them. These are power connectors for devices like disk drives. Polarized and can't be inserted backwards. Usually 4 multiply colored heavy guage wires to each connector. Not all of these must be connected.\n\n--Large 2 row white plastic connector (about 20 pins) which is the main power conenctor to the motherboard. Also polarized and can't be inserted backwards. 1 of these. Must be connected to the motherboad.\n\n--Small 4-pin connector, perhaps as many as two. Power connector for small drives (like 3.5" floppy drives). Not all need to be connected to drives.\n\n--Up to two additional connectors for the motherboard. One will have 4 pins, and one 6 pins (if memory serves). They are polarized and can't be inserted backwards. These are additional power supply lines for high current motherboard circuits. If present, and the motherboard has matching sockets, they should be connected. If the motherboard has no matching connectors, leave unconnected. If the power supply doesn't have them, and the motherboard does, stop. Carefully consider the total current draw of the various components on the motherboard and attached to it. You might have to (likely will have to) get another power supply to safely satisfy the motherboard's needs.\n\nIt may be useful to know that a great many power supplies don't actually behave very well. It's not easy to design a reliable supply with good perforomance at a reasonable price and in the size constraints within which a standard power supply must fit. A misbehaving power supply can damage your motherboard, the CPU, and everything plugged into it (expensive graphic card, perhaps?). If you've gotten a power supply made by someone you've never heard of, you might want to find a local hobbyist (or perhaps better a HAM radio operator) who can test the supply for you. \n\nPC Power and Cooling have a sterling reputation for the quality and reliabilty of their power supplies. Antec is also well thought of. Neither costs so much as to justify the risk of frying several hundred dollars of CPU, graphics card, motherboard, etc. \n\nSAFETY NOTE: These power supplies have lethal voltages inside. They are NOT safe to open, unless you know EXACTLY what you're doing, and even then they're dangerous as all get out. Furthermore, those lethal voltages will still be present for more than a few minutes after power is removed. Also note that many modern ATX and compatible machiens DO NOT turn off the power supply even when the front panel "power switch" is pushed and the computer shuts down. Most of the time they remain in 'warm' mode when apparently "off", and are still operating even when the computer itself isn't. Stay out of power supply innards! The only certain way to be sure the power supply is completely off (though it will remain dangerous for many minutes) is to remove the power cable. Putting it in a drawer, and closing the drawer, before doing anything further is quite sensible.
