With the introduction of the INTEL 80486 processors back in 1989, COMPAQ equipped its Contura “All-in-One” notebook series 2820 with these faster chips. Also the 80486 had a mathematical co-processor integrated in the CPU.

    I bought this computer from Marktplaats Netherlands with 25 EURO + shipping. The computer came with its original bag and charger. 

     If you check out the gallery you will see that this computer has some navigation maps from ANDRoute 1996 of all Europe, EU of that time at least. The GPS module was connected via its parallel port and there you go! A primitive but fully working GPS navigation system!

Back in 2009 when I got it the computer was running fine.

In 2016 I had a vintage computer exhibition and this computer was running Lotus (video game) and it started to have a fishy smell and randomly shutting down. I instantly knew the capacitors needed replacement.

In 2020 when I opened the lid, the hinges were stuck and I broke the plastics around them… It was like a horror show.

I decided to replace the capacitors and fix the hinges

The problematic capacitors are both located on the internal power supply , on the voltage divider board. There is a 330uF at 25V and a 180uF at 16V. Once these are replaced, there is no more fishy smell and the computer stays ON.

The hinges needed some lubricant applied and also the plastic was restored using some epoxy based glue to rebuild the broken plastics.
