Replacing power supply HP M8120N

How do we disassemble tower to replace power supply?. We need to know the sequence of removing hard drives, fans, disc drives, etc. to get to power supply to replace it. It appears that the entire computer needs to be taken apart to get to the motherboard to disconnect the old power supply and install the new one.

Here is the link for the upgrade and service guide.

This one is just as easy as 1) removing the side panel; 2) Remove the four screws that hold the power supply into position; 3) Remove the power supply cables from the motherboard (NOTE: If the media bay reader is in the way, you remove the front bezel by pressing the release tabs on the bezel and it will swing open. Remove the one screw securing the bay in position, then slide it forward so you can reach the power cable to the motherboard.); 4) Remove the power supply cables from the hard drives, cd rom drives, and other peripherals inside the PC. 5) Remove power supply...sometimes there is a button to push and it will slide out, sometimes not. 6) Replace power supply, then reverse procedures.

Thanks and please take a moment to rate as fixya.

System fan error


If you have replaced the fan and you are still getting a "Fan Error" then you have replaced the wrong fan. The system fan is not fitted to the top of the processor, it is usually fitted to the case.

My HP pavilion has stopped running, no power to tower, just a blinking green light in the back of the tower. Everything else works fine monitor, printer. Do I need another power supply. My computer is 10...


I strongly advise you to replace your old (VERY OLD!!) PC with new one. Do not worry, you will not lose any data from your old PC if you will take hard drive off your old PC and fix to new one. Anyway, if you still want to keep your old PC (NOT RECOMMENDED) you will have to buy new Power Supply and clean up your PC inside.

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

Please try to remove all the connections from your computer and also connections inside the motherboard, the power cord for your hard drives and also the power cord from the power supply to your motherboard.After that, remove the memory and clean the pin by using an eraser of the pencil. And then insert again the memory stick and connect all the connections from the power supply to motherboard and everything. Lastly reset your bios and put it back to normal again. Hope this would help. Thanks..

Dell tower desktop Dimension 5100. Tower makes whistling sound.


sounds like it could be a bearing in your hard drive. is this problem constant? If so, I would open up the tower and disconnect the hard drive and then power up the tower again. if the sound goes away--you need to get a new hard drive. If not, you could have some dust bunnies in your cooling fan.

The fan is very noisy


The post begs for the obvious answer: Replace the fan.

Now to be more polite, first you need to identify the failing fan and replace it.

A desktop system can have several fans. Case/processor fan (you can test to see if this is the effected fan by unplugging it for a minute or two from the motherboard (a couple minutes will not hurt the system).

The video card may have a fan on it (Often on the underside if a mini tower) Some video card fans can be easily removed but finding replacement fans can be a challenge. Normally if a video card fan fails, replace the video card.

Most often, the failing fan is in the power supply unit or PSU. If you are handy with electrical components, you can remove the PSU, remove the fan and replace it. If you are not handy electrically, replace the PSU.

Higher end system may have card cage fans to help cool hard drive/expansion cards and others have fans specifically to coll hard drives.

Most manufacturers have spare parts where you can buy parts or you can use google to find specific replacement parts or fan suppliers.

Power supply fan is makeing a lot of noise


1) Unplug the power cord and give the fan a good cleaning
with a soft paint brush and a vacuum cleaner.

i.e. Let the fans spin up by the vacuum and than bring
the brush against it.

2) If this fails, it's time to replace the fan:

a) Upgrade or replace the power supply enclosure with more
power/higher quality.

This is usually a good investment anyway.

b) Replace the fan only as described below:


Unplug the power cord

Open up the computer (remove sides)

Unplug all the power supply harnesses from
the mother board, drives and chassis fans.

Unscrew and remove the complete power supply
enclosure at back of computer (ie top of the tower)

Vacuum it out as much as possible.

Disassemble the power supply enclosure by removing
more screws and removing the metal cover.

Unplug the fan from the circuit board, remove it
and take it to a computer store/ builder.

buy another fan just like it

reverse the process to put your computer back together.

1) A new power supply should cost $65 to $120
depending on power and quality. The bigger the better.

But make sure it fits mechanically into the existing chassis
and that the AT generation matches ***********-board.

2) A new fan should cost $15 to $25. Makes sure it runs on
the same voltage, and that it is physically compatible.
