Question about Hi-Pro (HP-P401W) (HPP401W) Power Supply

1 Answer

I have the HP-2537F3R power supply on a computer. The LED no longer lights up and the computer will not turn on. I think I need to replace the part. There has been some additional hardware added to this computer since we bought it. The present power supply is rated for only 250W. I think I will need an upgrade to 350 or 400 or so. What are my options for compatibility?

Compaq Presario SR2150NX doesn't turn on. Front panel green light turns on but nothing else happens (no fans, no boot, no noise, nothing) Please advice


On the back of the Power Supply there should be a Green LED, When you power it on if it is flashing, this means that the Power Supply is dead and you need to replace it.

Hp desktop power wont turn on


When you powered it on, does the power supply fan spinning? If not, then you might need to change the power supply. It may got the led light lit on, but it does not have enough power to turn on the entire computer.

I think you have more than one problem there. Take it to a local PC repair shop and have them check it out. Five years is a good age for a computer though so you may want to think about buying a new one. Best of the Irish Luck to yer.

Hipro HP-d3057f3r computer power supply broken?


I have the same problem. I found this:

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=bph06788&product=12455#bph06788_section_2

  • Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:
  • If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.

    No longer turns on


    It's well worth replacing the capacitors, but this problem can be caused by a short on the power supply (Which is what the caps do). Most shorts that arise in power supplies are result of a shot transistor or diode and of course the electro caps. Check these while your changing the caps.
    Good luck with it.

    Printer will not turn on


    The all-in-one product will not turn on If the all-in-one will not turn on at all, follow the steps below in order to determine the cause:
    1. Verify that there is power at the wall outlet.
    2. Verify that the computer and the all-in-one product have a three-prong power plug.
    3. Remove the product cable from any power strips or surge suppressors, and plug it directly into a grounded (three-prong) wall outlet.
    4. For models that have an external power supply module, verify that the power supply module is plugged in correctly. Some power supply modules have a green LED built into the connector end or on the power supply module. This LED will be lit if power is present. If the LED is not lit, replace the power supply module.
    5. Plug the power cord into a different electrical outlet.
    6. If the all-in-one has an ADF with an external cable plugging into the back of the product:
      1. Turn off the unit.
      2. Unplug the power cable from the wall outlet.
      3. Unplug the ADF cable from the back of the product.
      4. Plug the ADF cable to the back of the product.
      5. Plug in the power cable to the wall outlet, and turn on the power.
        • If no change, the problem is not the ADF.
        • If the problem clears, turn off the all-in-one, unplug the power cable, and plug in the ADF.
        • If the error returns, the ADF is defective. Contact HP Customer Care to get the ADF replaced.
    7. Unplug the USB or parallel communication cable from the back of the all-in-one and try to power up the all-in-one. The computer may be grounding out through the communications cable. If this corrects the issue, check the grounding of the computer and outlet. If the above steps did not resolve your issue, contact HP for additional issue verification or the servicing of your product.
