The Compaq Aero was popularized as a line of computer handhelds produced by Compaq Computer Corporation. It was succeeded by the iPAQ line. The Aero name was first used for small sub-notebooks computers that Compaq produced in the mid-90’s, the Contura Aero 4/25 and 4/33c.

I had bought this computer from the local flea market for $5 in November 2016. The computer had its original bag and the external floppy drive but no AC Adapter. I was able to buy an adapter from eBay and it arrived quite fast. 

The next day after the adapter arrived I had plugged it  in and pressed the POWER ON button but nothing was coming up. The power LED was flicking a little but either than that, NOTHING!

 I decided to disassemble the computer and I found out that one of the power supply’s capacitors was bulky and needed replacement. Also the right hinge was broken so I glued it back using Poxipol (epoxy based glue).

After these little tweaks the Compaq Aero booted up like it was 1995!


Size, wight, the Trackball

I have to admit the idea with the trackball and the mouse buttons on the side of the case was a great idea for a small device such as the Aero. The control is much better than what you get on the Toshiba Libretto and probably better than the Omnibook’s mouse!


Keyboard, poorly engineered hinge system

The keyboard is the worst keyboard I ever typed on! Okay, not the worst but its clearly in my top 5! The keys feel laggy and sometimes you got the feeling they get stuck if you don’t press the keys on the center.

    I have one Aero 4/33C and my screen was broken.
    Do you have just the screen to sale?
    I’m from Brasil and I would appreciate your help.

    1. Hi Rogerio,

      Unfortunately I do not have a spare display for this unit. I think e-Bay is your friend on this matter.
