Einleitung

This fine computing device was recently discovered in an undisclosed warehouse where it was being studied by Top... Men.

What could be lurking inside this heavy metal box? A Golden Idol... The Ark of the Covenant... Giant Ants?

These are all possibilities, but there's only one way to find out for sure.

  1. Behold, the power of beige!

    • Behold, the power of beige!

    • Tech Specs:

    • 933 MHz Pentium III Processor

    • 10 GB PATA Hard Disk

    • 512 MB of PC133 RAM

    • 16x DVD-ROM and 3.5" Floppy Drive

    • Life Experience

    • Compaq was bought by Hewlett-Packard in the early 2000s. Let's just say that the transition could have gone smoother.

  3. We're going to remove the heavy steel casing by pressing in on the tabs located on the sides of the cover and then pulling the cover forward. There are a few hooks holding the cover in place, so some rocking is necessary to free it.

  4. With the cover removed, we are greeted by some ancient hieroglyphics. Green tabs and arrows identify how the rest of the major components can be removed. A diagram of the motherboard and common diagnostic codes can be found on the interior of the chassis cover.

  5. The various drives are mounted on a single hinge that flips forward. Just pull up and it will click into place. The PCI riser is one of the few things missing a green label. The release button is the silver tab towards the front of the computer. The card slot is fragile, so use an even amount of force and pull straight up to remove the riser board.

  6. Time to remove those pesky cables. We'll want to be careful since PATA ribbon cables have many pins that can be bent. Tape. Why'd it have to be tape? We'll just leave that one cable taped to the drive hinge where it can't hurt anything.

  11. It's finally time to remove the motherboard! We'll start by releasing the I/O port bracket on the back of the computer. This bracket is under pressure and will fly across the room if it isn't held down. (That may be why it's called a "Flying Serial".)

  13. Take a moment to admire the motherboard in all its glory! In lieu of a dedicated video card, the Intel 815 chipset utilizes an integrated graphics solution. Needless to say, gaming on this machine would be painful at best. The bicycle is a complete mystery. Some people have suggested that a tiny mouse would pedal it to drive the cooling fan. Others have said that it was placed there by Freemasons to locate buried treasure.

  14. The RAM can be removed by unlocking the white tabs on each end of the modules and pulling up. Here we find yet another sign of past upgrades.

    • Gently push down on the red tab.

    • Squeeze the red tab towards the fan and then lift the cooler.

    • Using too much pressure can crack the processor and ruin your day.

    • We can now see the CPU die since this version of the Pentium III does not have an integrated heat spreader. This design is called a flip-chip pin grid array (FC-PGA).

  16. Removing the CPU requires a steady hand and can be slightly intimidating. A beige lever keeps the CPU locked in place. Pull it away from the processor and then up. The processor will move towards the group of capacitors when it is unlocked. Now would be a good time to ground yourself if you haven't been wearing your nifty anti-static wrist strap.

    • Completely Unofficial Compaq Deskpro EN Repairability Score: 10 out of 10 (10 is easiest to repair)

    • Most common repairs can be done with one tool.

    • Faces remain unmelted after removing the cover. (Always a good thing.)

    • Finding replacement parts may require entering a Temple of Doom/RadioShack.

Personally I’d include ease of finding suitable replacement parts in a reparability score, I’ve worked on these things and would rate them at 8.5-9.5 for non-standard motherboard, motherboard mountings, and power supply.

If purchasing rather than leasing, I think the point was retire the first few that break out of warranty, and start parting them out. Compaq was very good about keeping the same line going for a long time so the parts would be compatible.

Awesome! I love these machines. I’m pretty sure these ones will run a Tualatin PIII if you upgrade the BIOS too.

Mike Roach - Antwort

do you know, how to oil noisy power supply fan in this computer? I tried but I can’t open it?

Thanks for the quality
