Question about Intel D865PERLL Motherboard

Intel D865PERLL Motherboard will not power up

System will not even turn on the power supply when the “Power On” Switch is pushed. Power supply & CPU fans & case fans stay off. Had a bad lightning storm. System was off but plugged into a UPS. UPS still works with other PCs. No obvious burn marks on the system or power supply . 5V power LED standby power was still working. Power On Switch was checked & OK. New power supply installed but system does not power up (no fans running).

I don’t have detailed schematics.

    Good morning Mike,

    Thanks for trying. FYI, I was deliberate in typing Intel D865PERLL. There are apparently several versions of the Intel D865PERL motherboards. The "LL" version has the LAN and Firewire built in. That is the version I have.

    FYI: Here is the Intel link to the details of the differences in the Intel D865PERL motherboards.

    I already have the pdf file whose link you sent. Unfortunately, it does not give a detailed enough schematic indicating which IC controls the power on for the power supply and motherboard. I was hoping there might be a small (16 pin DIP) that could easily be swapped to get the board running again.

    Do you have any additional ideas of where to look?

    Thanks for your help, Jim

    Do you have another Intel Motherboard ATC form factor which still supports Socket 478, with USB, LAN & Firewire builtin, AGP & 5 PCI Slots, that might still be available?

    Regards, Jim

    Also Intel doesnt build MOBOs only chipsets.

Since the board won't power up, try a jumpwire solution to start it through the ATX power supply connector. Green wire on ATX power supply connector to ground. You may have a fried connection to the power on line, and it can be anything from a blown resistor to a fried copper trace within the motherboard (which is multilayered)

Hi nkda2000, this is as close as I could find for power schematics. Intel D865PERL

(There is no Intel D865PERLL board). Sure it's a typo. Have done searches for D865PERLL & found it (Not on Intle's web site) but when looking at the specs it's listed as D865PERL. (One L ) not two.

I hope the Technical Product Specification pdf can help you check the power on the motherboard.

The computer wont start up, i can see a green light on the motherboard and nothing else. even the power button wont show up led light.

This can be a power supply problem or a motherboard problem.
One or the other has probably gone bad and must be replaced, if this is what happened.
Start by disconnecting all things from the motherboard except the CPU and memory.
If the system starts, then you've ruled out the power supply, CPU, motherboard, and memory.
If not, remove the memory and see if it tries to start. If so, then the problem is the memory.
If not, then it's definitely the power supply, CPU, or motherboard.

Intel D815EEA2 mobo won't boot - no clue to why not.

I know, this is a very frustrating situation...
Unfortunately, the only reasonable way to find out what's wrong is to swap components with a reference system, until you found the defective part. I hope you have another P3 system available to swap parts.

I would do it this way:
  • First check that the power button is connected correctly.
  • Swap the memory from the faulty system to the reference system.
  • If ok, put it back into the faulty system and connect the power supply from the reference system (or some other known good one) to the faulty system.
  • If this doensn't help, swap the CPU from the faulty system to the reference system.
  • If the CPU is ok, the motherboard seems to be defective.

Fans run without turning on front switches

Hi Gene,

If you've installed the cpu and hooked the fan to the power supply plug, which is just left of the cpu mount, then the board if connected to the power supply cables, it should start up. Regardless of the front switches. However, you probably don't want to start plugging in the power cord until you have all of your components in place and ready to close up the case. First you can create a shock by just touching the board and that can damage the board. (I speak from my own experience :-( .

But once you get the power switch plugged into the board that should take over turning the rear power supply on and off (Including the cpu fan)

Good Luck and don't forget to leave a rating, based on my solution.

Thanks Mark

Motherboard not working correctly.

The way that I solved the problem was to unhook each and every connection to the motherboard except for the 4-pin and 24-pin power supply connections, the processor, the cpu fan and the power on switch connectors, once I have done that, then I plugged in the power supply and turned it on, in which that worked! After that, I would hook everything up to the motherboard one piece at a time, in which after each piece I would turn the power supply on again to see if that was the problem. Starting with the hard drive, the memory sticks and then the DVD drive, and found out that was the problem. The cable between the DVD drive and motherboard was the wrong cable for that motherboard. I will purchase a new cable and see if that works!

Cpu on but does nothing

I once plugged in the power cable of the floppy drive incorrectly, and it shorted out the power supply, floppy drive, and motherboard - but the smoke pouring out made it obvious what had happened.

Could this be the case for your issue? Is it possible to try an alternative power supply to see if the system then boots properly?

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
