20 Most Recent HP Compaq 175-Watt Power Supply Questions & Answers


the fuse blew for one reason, overload, and stops the fire from happening, that is its #1 job, the fire thing and smoke bad thing
and deathhh..
Never have PCs on or servers when doing power feed swaps.
of any kind unless you have the type that has expensive power frequency syncing,.. and full load dump protections. (ask)
let me guess you dont have this, nor a UPS on your server to save it.
what is this, it has a real name, this is generic, phrase.
embedded network.+
what ever this phrase means?, and what it is by name and model unstated, all I can say its not on a UPS, nor is its internal battery any good, or other power backup issues bad inside.
coin cell in side bad," or you load dump glitches its so badly, well, no need to say why, there its obvious.
even some homes the cable modem has battery now and more are bad. now. (huge problems with ignored batteries)
doing exactly that. as expected too.

Your server has RAID, like mine (DL380G7) has Cash ram
with battery on it , 1GB here, if bad battery on this, you will lose data on your HDD if you kill or bump power, AC, called load dumping, My RAID card allows power loss. and no data loss ever.

also load dumping blind invites, surges of overvoltage and blows to H3LL very expensive electronics. boom dead. $%$$$$
sounds like you need a real UPS there, between H3LL and $$$$ things.
This is how 911 service centers are built, done many.
ground up,. not just thrown together, not even close.
The run a HUGE UPS, $20,000 worth or more.
for you do use a UPS we need your load, actual (watts)
then 2x bigger UPS.
The gen set must be at correct voltage and freq, before the switch or even UPS can be damaged,
but some can run as low as 100v and 50hz.
so read the UPS spec first before buying one and to be sure the gen set cant damage it. (no gen set stated BTW)
In Hospital here we have a genset monitor that makes the genset delay the switch over until, all is perfect then switches. see?
or you will blow lots of things up. endlessly.

There's an old saying about "The lights on but nobody's home" :-)

It seems like you are writing about a Power Supply based on the picture and the section you posted in. Did you change the power supply? If you did you probably have problem on the mother board. That's pretty fatal unless you have a computer repair shop you are working in. Swap the CPU, swap the Motherboard.

Hell just buy another computer as cheap as they are these days. :-)

The fuse on the power supply would be on the primary side (before the transformer). It's usually either under the cover, or it's in the red voltage selector switch.

But...if you have some lights on the motherboard, it's not the fuse. The power supply has to send out a couple different voltages (usually +/- 5V, and +/- 12V). If parts of the computer have power, then you probably are missing one of the voltages. You could get a voltmeter and check each one, but chances are you will just need to replace the power supply.

They all do, I believe, I installed a new one, into my computer system not long ago, are you sure your power supply is one that the computer can handle? You shouldn't have that much of a problem - I wouldn't go pulling apart the wires on the power supply, its made like that for a reason, what you could try is see if your power supply has seated properly, sometimes if your not working on a flat surface the power supply plug won't go in properly and will not be pushed in all of the way, try laying your computer on its side, and pushing in the plug also, each motherboard has a certain amount of plugs for example 20 and 24, some motherboards want it to be a 20 power plug and others want it to be 24 power plug, thats the plug thats connected to your motherboard, that I'm talking about. make sure you have the right number, and that the motherboard plug and the power supply plug match, basically have the same number of connectors, (I mean that little white plug at the end of the red,yellow,black, wires, I hope this helps. ps- I really had to push on the white plug to get my seated properly

if it turns the fan, it works, if not its the motherboard, you can find them on ebay

HP Compaq... | Answered on Feb 04, 2009


hi well install a couple of wings and your good to go!....:) the fan starts when the power supply is heating up from a big pull of current all you need to do is service the little jet - unplug the power - take a can of compressed air and blow it on the fan (while working to) - after you cleaned it take a spry oil can (WD40....) with a nozzle and lubricate the hinge of the fan (not to much, while working only if the hinge is opened from outside) good luck

If this issue started with a motherboard error that appeared to be a faulty CMOS battery and then it started incorrectly detecting your memory and now is asking for a password it could be a faulty motherboard. If you are 110% you or anyone else has set a password on that laptop then I would say your motherboard needs to be replaced. It is a difficult process to reset admin passwords on most laptops due to a security chip that will prevent the trick of removing the battery from working. In all honestly if no one has set a password and the motherboard THINKS someone has then even if you reset the password you will still have issues. There is a small chance your CPU or RAM could be defective. But, again going back to it saying you have a password set that was never set. It just yells faulty motherboard unless someone has set a password without you knowing.

If you've got working Wi-Fi but your wired ethernet connection is not working, the first thing to do is turn off the Wi-Fi. Believe it or not, this might tell you that the ethernet is working. ... Right-click on the icon, go to Open Network and Internet Settings, then the Wi-Fi tab, and toggle off.

This Error 1702 problem can occur if all the following conditions are true:
  • You originally installed Office from a network administrative installation.
  • The network administrative installation is no longer available to you.
  • You are trying to use an Office CD-ROM when you are prompted by the Windows Installer for an Office source location.
  • You click Cancel when you are prompted to insert the CD.
Because the files in an administrative installation are uncompressed, and the files on an Office CD-ROM are compressed, the Windows Installer cannot resolve the differences between the two source types. The resolution to this problem depends on whether you can obtain access to a network administrative installation. Use the following methods, as appropriate to your situation.

If the original administrative installation from which you installed Office is not available, you can use a different administrative installation for the Office source file location. To do this, follow these steps:
  1. Click Start and then click Run.
  2. In the Open box, type a command line similar to the following, and then click
    OK new network path\Setup.exe /fvm package name.msi
    where new network path is the full path to the alternative network administrative installation, and
    package name is the name of the Windows Installer .msi package on the root of this administrative installation (for example, Proplus.msi).
  3. Click OK when the update is finished.
