I will be picking up a Compaq Presario 7210 soon, but I can't find much information about it on the internet.

Does anyone here have manuals, advertisements, drivers and specs about the model? such things will be very usefull for me.


Here is a link to the unit that I bought: http://www.marktplaats.nl/a/compute...a871b0d84f75c3056cc6db858f31&previousPage=lr#
(Notify me if the link expired.)


Thank you very much for reading.
 
Can't say as I recall that model specifically...but it should be pretty standard by the looks of it and remembering similar-looking models of the day. Pull the cover and take a look. Likely a generic Cirrus Logic video chip in it. Somewhere around here I have a set of the Compaq Support Reference Library CD's from back in the late 90's when I did Compaq warranty repair work at a local computer shop...the QuickSpecs would have all the details. I thought maybe they would still be online somewhere, but no such luck.

If you get stuck, post here again, and if you don't hear from me, PM me to remind me and I'll see what I can dig up for you...there's a chance I've got drivers on those CD's as well...I don't remember for sure though.

If you can't find anything about the 7210, try the 7212 which seems to be identical enough.



After a few weeks of it working, it no longer wants to boot, almost nothing at all.


I have a Compaq Presario 7212 (Or Compaq Presario 7210 ) AT style motherboard with a Pentium I that I was installing a secondary harddrive into.
Everything was working until that point, it passed every Norton Utility and Compaq diagnostic test.
The system was running while I was looking at some connectors, I accidentally kicked the harddrive cradle, moving it along its rail slightly and then everything shut down. The power supply was making a weird high pitched noise, as if water was boiling, for a short moment. I'm not smelling anything burning inside the powersupply or on the motherboard.

Now the board no longer wants to boot. The only things that turn on for a moment are the keyboard lights.
The harddrives still do their thing when I turn on the power, the harddrive light from the motherboard even lights up. But the 'power on' light from the motherboard does NOT. My screen does not get any signal either.

I have re-inserted every powersupply connector. I have put back the original 2 4MB EDO ram simms supplied by compaq. I disconnected the harddrives, floppy drives and tried different configurations. I switched out the Pentium I CPU for an other Pentium I

None of that has worked, what should I try next?

Thanks for reading

That would be great, and I need you help also. It no longer wants to boot, read my update on that above this reply. Hopefully you know what has happened?

I hope so, thanks!

Sounds like you may have created a short when the power was on, forcing the power supply in to self-protect mode.

My first thing (personally) would be to swap out the power supply just to eliminate that cause (I've found this to be unlikely, but you want to eliminate it).

Edit: actually, no power light, but the power supply starting up, I wonder if you shorted the lines that go to the power LED damaging the power on circuit??

The keyboard lights power on for a moment, note that.

Is the power-go/on circuit of the PSU slow enough to be measured by a multimeter? or are you talking about something of circuit on the motherboard? or both?
 
I'm probably confusing things here - I just realized you said this board is AT powered not ATX. If it's got a big mechanical switch on the front, then ignore that point. I'm just so used to Pentium class machines being soft-start ATX style,

Do you know what / where the hard drive cage would've touched when it shifted?

ATX power supply: https://upload.wikimedia.org/wikipedia/commons/8/86/Power_Supply_ATX-450PNF.jpg

AT power supply: http://www.esapcsolutions.com/images/DSC00886fsb.jpg

Mine uses the AT connectors (P8/P9) and has a hard power switch. Windows 95 was not able to shutdown the computer, this had to be done manually after the screen said "It is now safe to turn of your computer."


The harddrive cage only shifted a few CM, it didn't touch anything that is was not already touching.

The IDE and Molex cable shifted of course. As did the floppy drive data and power cable, as it is connected to the harddrive cage.
 
If your power supply made a weird noise, then it is certainly suspect...not sure why bumping the hard drive would have caused that though. I would also think it could easily be something other than a standard AT power supply...but I don't know for sure. I need to see what this thing looks like...may jar some memories from back in the day if I was to lay eyes on it. I saw my Compaq CD set here just the other day...I'll see if I can dig it out here shortly.

If you haven't already done so, I would try turning it on with the hard drive completely disconnected.

One power supply post and I'll stop spamming the thread with info... First the "Functional Description", then the connector pinout...should be able to test from that. Here's the block diagram listed below...in case it is useful: blockdiagram.jpg


Publication Date: July 1995
Source Document: Compaq Presario 7100 Series Personal Computer
Maintenance and Technical Reference Guide
Document Number: 188914-001

The power supply provides four DC voltage levels for the computer system:
+5VDC, +12VDC, * 12VDC, and * 5VDC.

Power-On Sequence

At power-on, the +5VDC, * 5VDC, +12VDC, and * 12VDC outputs are monitored.
A fault detection occurs if any of the monitored output voltages do not
reach the minimum low-voltage limits within 1 second. The POWERGOOD signal
goes active (high) between 100 ms and 500 ms, after the system voltages
reach the minimum low-level voltage.

NOTE: Output loading determines the order and amount of time required for
the system voltages to reach their regulated voltage levels. Figure
9-1 shows a functional block diagram of the power supplies used in
the Compaq Presario 7100 Series Personal Computers.

ILLUSTRATION OF Figure 9-1. Power Supply Functional Block Diagram

Power-Down Sequence

The power-down sequence is dependent on the same variables as the power-on
sequence. The output load determines both the order in which the output
voltages drop out of regulation and the time remaining after the POWERGOOD
signal becomes inactive (low).

Fault-Detection Circuits

The fault detection circuit automatically shuts down the power supply
until all faults are removed and the AC power switch is turned off then
on. The minimum time period required to recycle the AC power and to return
to normal power supply operation is 10 seconds.

Power supply faults that trigger the protection circuitry include:

Thermal overload: The protection circuit triggers if the power supply
becomes too hot as a result of fan failure or a
restriction of the air flow.

Overvoltage: The +5VDC output activates the overvoltage crowbar circuit
that triggers the protection circuit when the output exceeds
+5.60VDC to +6.80VDC.

Short Circuit: The protection circuit triggers if any power supply output
is shorted to ground or to another output. This function
prevents any shock or fire hazard.

NOTE: The minimum loading requirements for the power supply must be met at
all times, to ensure normal operation and to meet specifications.

I'll try to get a multimeter soon.

Also know that plenty of chips are still getting warm, including the CPU, int S3TRIO64+V, ESS, SMC and Opti Viper.

I am not sure if this still happends when ram has NOT been installed, I will test it out soon.
And yes, before you ask, I have already tried to swap ram and tried different combinations.

Edit: The BIOS chip only seems to get warm when I have memory plugged in.

Did you try connecting a speaker? When you power on you might hear a POST code beep. Also try that with no memory installed. Most motherboards will report a POST.
If you get a POST code, at least you know the processor is running. Chips getting warm indicates power is available.

Alright, I'll try your suggestion.

I have tried it a few times with or without memory, none of the situations gave a POST code beep.
 
If your power supply made a weird noise, then it is certainly suspect...not sure why bumping the hard drive would have caused that though. I would also think it could easily be something other than a standard AT power supply...but I don't know for sure.

Hello Weskey,

I've checked the PSU voltages, they seem to be next to spot-on. Is there any way to test the power-good signal on the PSU or motherboard? and if that didn't work, would the harddrive still turn on, blink lights and motherboard chips warming up?

I don't have any experience with this, so is there anything I could try next? I can take high res pictures of the motherboard and its chips if you want.

Thanks for your help,
Niels
 
Someone here may know more about it, but I'm thinking the power good signal comes from the power supply, not the computer...? Are you getting voltage on pin 1?

You've tried it without RAM and get no beeps...are there any add-in cards installed that you could remove? Troubleshooting a problem like this, I usually remove everything I can and try to get a beep code out of it... Certainly starting to smell like a bad power supply or motherboard...

Have you tried clearing the CMOS as well?

Wesley
 
Yes, there is voltage on pin 1.

Yes, all add-in cards have been removed. PSU seems good, now I need to test the motherboard. Which chips progress the power-good signal and distribute everything to the various IC components, including the CPU? would chips still warm up if the power-good signal or progress chip was faulty?

Yes, cleared CMOS as well. Note that the power-on light in the case does not burn, but the hardrive-activity light in the case does.
 
Last edited:
Maybe I could trace down the line of the power-on light? perhaps it would lead us to a broken chip.
----------
Alright, so one of the power-on lights that should be on traces back to the SMC chip. hmm. I guess one could figure out how the chip works and test the conditions of the power-on light burning. I'm not sure yet if both LED's use the same power line, so the problem could come from two things.

The harddrive activity light does work, its connected to the IDE port.

I will use pin numbers and macro shots later when I have the time, this will make my description much more usefull.
