Compaq Evo boot time beep codes

[Hul Tytus]

Anyone know the meaning of the boot time beep code: beep beep pause beep?
This occurs somewhere in the boot sequence and the machine stalls.

There were a lot of different EVO/s. Many of them also had diagnostic
lights.

You have to find your specific EVO modelno at HP/Compaq and look up the
post codes.

Here's a non-specfic HP beep code page. Navigate from there to your
specific product and then its troubleshooting section. If yours has
diagnostic lights, similarly find your model.

Needs a model number. Like

Compaq Evo D510

Evo by itself might not be enough to find the info.

For home-built computers, you look on the right-hand side of this
page, for the "beep code" links. However, Compaq/HP is not listed here.
Award, AMI, and Phoenix are popular retail motherboard BIOS makers.

As an alternative source of info, I'd have to find the
HP hardware maintenance manual for that exact model (if
available), and see if the codes are listed there.

First take it to "barebones" config: minimal accessories. Although do
note how components were originally laid out.

You can try removing, reslotting memory;- What your options are given
how it's populated.

Clean board contacts insertion pins, both sides, with an ink eraser
and brush. Spray insertion slots with decent quick-dry electrical
contact cleaner.

Check it for a cardboard config: IOW, prop the MB up, isolated on top
of a piece of cardboard, plugged into the PS and otherwise "normally"
assembled. You're looking for continuity or case mounting issues,
unlikely though that would be with a BIOS audio fault report.

Same goes for reseating the CPU.

Video: try alternatives if you're card-mounted and have them (another
video board or not limited to only on-board graphics).

Get real friendly with the pin-short CMOS reset: A "stuck" BIOS is a
PITA, especially when it's not especially so "smart" about picking up
changes in general hardware or peripheral [re]mounts.

COMPAQ is not in the MB biz. They usually have custom blueprinted,
OEM production runs contracted off Pacific Rim facilities. Sometimes
they're rebadged to specific model MBs sold by the MB name, itself.
Which may be of help, to know you're not limited to the only game in
town, COMPAQ resources.

I've bought MBs like that before, for dirt prices. All is fair
regarding involvements of love, war, and the business of barely
limping computers with broken BIOS's.

Many thanks Mike. I'll give the hp/compaq web site a try.

Thanks Paul. The model # appears to be D51S on this machine, which looks
close to you're suggestion.

There's a table here.

First, download the file. Change the file extension to .pdf if you are
on Windows. Linux might be able to deal with the file without needing
.pdf slapped on the end, because Linux checks for key bytes inside
the file to determine file type. But for Windows, you'll need PDF
on the end. If the browser screen fills with binary, don't panic.
Wait for the filling of the browser page to finish, then
select "Save" from the file menu and save it off as
c00704816.pdf . Normally the "binary dump" behavior only happens
if the server side is missing a MIME type declaration. It'll probably
download OK, but could really use a file extension on the end.

Open in Acrobat, head to page 51 (Appendix A doc page 4-1 "POST Error messages").

The beeps are measured in "longs and shorts" on this machine.

In addition, page 64 just happens to casually mention, that
they extend the codes by using the keyboard LEDs and the
power LED on the casing. The LEDs will start to flash
for certain errors too.

Try to record the "pattern" to the beeps, as well as
the LED flashing if available. Maybe that will narrow
it down a bit.
