HP Pavilion 540n power supply & front panel pin schematic info
I am trying to move a HP Pavilion 540n to a Gateway LPmini Tower (GP6-350) I am doing this because the small HP case does not allow enough ambient air movement and the gateway is a large case... It will also be a performance sleeper of sorts using the Pent 11 Gateway Housing, as I want to create another dual boot system, for my next users group meeting... I have cutout the restrictive power supply opening for a generic power supply. Discovered the bolt pattern was already complete, I only had to make a round area for the fan, and a small Dremel cut for the female 120 volt connector... I could not get the system to power up using the Pavilion 540n power supply, so went for a larger HP power supply... both fit easily in the resized power supply area... http://support.gateway.com/s/CASES/B...b0052506.shtml I also moved the Gateway front panel pins into the HP front panel block and for one reason or another can not remember or find my color coded drawing... Still looking for a webpage to make certain I have wired the Front panel pins correct... Front Panel pin- http://support.gateway.com/s/CASES/B...b0043415.shtml * * Now the problems, I believe I moved everything correctly but system will not power up, have two questions * * Question: I could not get the system to power up using the Pavilion 540n power supply, so went for a larger power supply from another HP... It this a wiring problem? I am not able to find a comparison of the power lines to know if the Pavilion 540n power supply has an odd proprietary wiring schematic. Pavilion 540n power supply = Bestec ATX-1956D HP P/N:*0950-4106* Generic Power supply = HIPRO HP-D2537F3R HP P/N: 5187-1098 * * Question: Pinout on the motherboard does have a missing pin, and the block has a white insert for that missing pin... Most Blocks I have seen are double row, but this one is different and I can not remember how it was installed, nor can I find the drawing I made to change the gateway switch and LCD lights... Had a number of phone calls on other systems during the time I was completing my drawing... Might someone be able to post links to give me a visual for the power supply wiring and the front panel pin layout for the HP Pavilion 540n... JR the postman |

A decent housing upgrade for this computer system that was installed in a small form HP case... The Gateway Housing can easily accommodate the HP Pentium lV 1.5 system... I have several E-machines with Biostar motherboards used as a replaced, so will try to move a EM T-2778 in the next few evenings, they use a normal power supply but have a different back panel that will present a different problem... Maybe a $35 generic Computer case is better in the long run, but then my recycling efforts would not be accomplished.... As I have already recycled the E-machine with the Biostar motherboard and a decent power supply... Funny how the cheap Bestec power supply is also the reason the E-machines originally were tossed aside... JR the postman |

"Funny how the cheap Bestec power supply is also the reason the E-machines
originally were tossed aside." Not funny at all. Downright sick and disgusting. Seems like GateMachines and HPaq do not give a damn about the damage done to their reputations by their use of the Bestec junk. The lousy power supply alone is ample reason to avoid buying Presarios, Pavilions, eMachines, and Gateway boxes. I doubt that HPaq has the nerve to foist off the Bestec power supplies on corporate customers who buy the business-class Evo product line. I forget though, because it's been a while since I handled an Evo...

The missing pin on your other supply (white wire) is a -5V. Some better 20 pins will have it (atx 2.0.x spec and some atx 12v), most 20+4 or 24 pin power supplys will not. Just get a fortron like this one: http://www.newegg.com/product/produc...82E16817104931 or a similar sparkle (fortron makes sparkle) if you want to be cheap or don't like black http://www.newegg.com/product/produc...82E16817103484 Both of those should have the white -5v pin provided they haven't revised it. I have had good luck with fortron as HP/Emachine/Compaq replacements. Oh yea, fortron underrates their supplies, so your getting a really good power supply at 350w, it can probably handle what others 400-450s can. |
