I take it that it is either the button connection or the power supply.  How do i check both?  How do i change both?  I have a down computer from the same era, can i take the power supply from there and install it?\nThanks

If your power button is bad then yes, you can probably take the button from the old one (if it is the same - not all are).  The old power supply may or may not be the same - you may have an AT supply in one and an ATX in the other.  If the power connectors look the same (the large ones that plug into the mobo) then yes, replace it.  You need not install it into the case first to see if it works, just connect it to the mobo, connect the hard drive and see if it powers up.

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.

Is there *absolutely* no power? No orange light even? Maybe the power outlet you're connecting it to is faulty.\n\nIf you're getting the orange light, it might be a video card problem.\n\n==============================================\nI hope you see this, because I couldn't email you because your ID isn't confirmed.\n---------------------------------------\nRe: No Power TO HD Monitor\n\nAh, i didn't read your question properly.\n\nCheck the power pins on you old monitor. The place where you plug in the power cable on your monitor.They might be covered in black sooty material if something blew up. \n\nOr maybe the fuse inside the monitor is blown. If you can open it up and check that out, and that IS the problem, you can get it fixed for a few $s. For less if you have the equipment and know how to solder.

There should be a power connection. If not, ask your vendor. Otherwise, for installation, visit here:

It would have helped if you had put down the make of the computer. They open up in various ways. If it is new, why not go to the shop where you bought the parts and ask them, or at least give them a call.

1.check your power cord for the computer\n2.try plugging it into a different electric plugin place\n3.make sure the power supply fan is running on back of the CPU tower

Hold the botton for 10 seconds and see. some computers are made or even programed that way on XP.\n\nIf that doesnt work, Unplug and check if it will power on using batteries. If nothing check yur cord cause it may be bad meaning yur laptop would not turn on or even charge the batteries. \n\nI f the cord works, it could be the switch on the laptop or the power source. Check yur cord first cause when u carry the laptop by a certified technician, he may charge u plenty and next thing nothing wrong with the laptop itself. Laterz.

Try turning on the monitor, see if it is plugged in right.  If none of that works don't hit it with a sludge hammer, bring it into a computer store.

if its a desktop you can try: open the tower and there is a lil battery and the power cord remove it for like a minute, one minute! not 15 sec. and replace the battery and power cord and turn it on you should be able to get in

Did you have a power outage?  Surge perhaps?\nSomething took out the power supply right?\nIf you aren't getting any kind of beep code or anything and everything seems to be reacting normally.  The very first thing I would do is check to make sure the monitor didn't get toasted!\nAlways verify the monitor isn't fried before you go to the MB and other internal parts of the pc for troubleshooting a video related issue.  Did you get responses from the hard disk, or cd rom after the power supply was replaced?

Its prob the power supply. Does  the fan turn on ???\nYou might want to replace it ( $ 60 ) . Also make sure that the power button is on . On the back of your computer theres a little button . \n\nAlso check out my free computer articals at http://www.cityredding.com/computerhelp

depending on how new your system is or maybe how old, your power supply might not have enough juice to give it power. this was a problem i had before, i just had to buy a new power supply and that solved it.

Black--or blank ?  \n\nIf it's black, then It sounds as if the power saver function might be on the fritz.\nUsually, striking a key or wiggling the mouse brings the last image on the screen back up.  Does the monitor have a small light on the front that is green when the screen is active? If that light turns yellow when the screen goes black, that tells you that the power saver function is on.  \n\nIf it's blank [not black], then I don't know what to tell you.  Call tech support and try not to lose your temper with the overseas representatives.

check that the elctricity cable is plugged correctly, then ckeck the power supply or just waste some money on going to a professional guy you know. I hope i helped you.

Check the battery..Go buy a new Battery.. See if it boots up then..If it dosent then it looks like a computer doctor is needed.Could be costly. If its an old one. it might pay you go buy a newer one.

Why did you take the battery somewhere to be charged if the laptop is not on but you have it plugged in you are charging the battery.  Check the metal connectors on the battery for corrosion, dirt, etc....  When you hit the power button does it make any noise(beep, humming?)?

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.
