Ask Slashdot: Is There A Screen-Less, Keyboard-Less, Battery-Powered Computer?

Long-time Slashdot reader Wycliffe writes: So I have a travel keyboard that I love. I can carry my OS on a USB flash drive. There are several options for portable battery powered monitors. The only thing I'm missing to have a completely modular laptop is the CPU/MB/RAM... I can get a laptop but it seems silly to carry around a laptop with a keyboard when I never use the keyboard. I don't need a long battery life, if I need more than an hour then I can find somewhere to plug it in...

I've thought about buying a small box like a Zotac and trying to replace the hard drive with a battery -- but does anything like this already exist...? Also, are there any systems like this with decent specs? Most stuff I see like the Intel Compute Stick are horribly underpowered compared to a decent laptop.

The original submission drew some interesting discussion. Another option is "a good x86/x64 tablet that I can install Linux on" -- especially with a decent processor -- or "laptop-like systems that got rid of the screen entirely... I just need the travel CPU part without the added weight of a second keyboard and monitor." So leave your best suggestions in the comments. Is there a good, lightweight computer that's battery-powered without a screen or a keyboard?

      I bought it a couple of years ago, along with a docking station. The tablet is horribly constructed, too heavy to be used as a reading tablet, it has a plastic back that gets deformed overtime and won't fit anymore, and the batteries that came with it puffed up out of nowhere (at least they didn't explode).

      Docking Station was also very poorly built. It has a single proprietary connector that supports the entire weight of the tablet that eventually gave away... I had to dismantle the whole thing, pull the connector out of the docking station so that I could make it work again.

      It also puzzlingly has a microUSB port for charging, but it needs a proprietary brick to supply enough power to charge... horrible decision that goes against the standard. It won't work with external batteries or regular smartphone chargers.

      Other stuff you might want to know: it uses a non-standard size for m.2 SSD storage that is hard to find and very expensive, power button is very easy to break, and despite having core i5 models and such, it's actually dual core and a series of CPUs designed with power savings in mind, which means it's far less powerful and sluggish than a Surface Pro 3 or so.

      The whole thing smells like initial prototype for a tablet that Dell decided to sell. I got so fed up with it's quirks and problems that I ended up abandoning it and buying myself a Samsung Galaxy Tab S2... which is why I even started experimenting with Ubuntu in it in the first place.

      What I'm trying to say is this: perhaps, if you can find out someone who tried to do a similar thing with a more robust tablet, it'd be a better route. Dell deserves only shame for putting out such a shoddy product in the market. :P I've been trying to find out if there are other smaller Windows tablets from other brands that will also take Ubuntu, no luck so far. I remember there were a bunch of them of the 8 inch type that came out around the same time the Venue also came out, but I'm finding hard to get real experience information...

      Anyways, here's something else I've been looking into since yesterday, thanks to your post:

      Wow, I'm seeing there are others / new ones in the Pico PSU form factor too. i.e. some have wide input voltage range and thus built-in converter/regulator (because your battery will go 13V, 12V, 11V, 10V...), others just say "input 12V" and are made with a power brick or laptop PSU plugged to the mains in mind.

      i.e., to be 100% specific : this one is specifically advertised for running from a car battery or in a car (or in a truck), where a "picoPSU-90" at half the price is not. (I will suppose the picoPSU-90 is exactly what's needed if you have very clean and close to 12V power to start with)

      a bit more power hungry than an Atom system (cheap Celeron/Pentium soldered systems are rebranded Atom. sic)

If you are thinking of some cabin off the grid, get a generator or solar panel. And even if using it while traveling is not a use case you are interested in, the laptop will be way cheaper and better than some battery powered screen plus a battery powered single board computer. Just the battery powered single board computer will run you entry level laptop prices, and the monitor will probably be more than that alone.

    One potential gotcha to think about- I'm not sure how many USB monitors require USB3. DisplayLink makes most of the chipsets, and their origins are in USB2 but I'm not sure how well their newest USB3 products do when attached to USB2.

    There's the "is there enough data" question (but their DL2xxx chipsets did 1080P on USB2),
    And there's the "is there enough power" question, since USB3 offers 80% more juice (0.9A vs 0.5A).
    Also I've never heard of anyone try to compile DisplayLink's proprietary drivers on ARM, so more cross-your-fingers.

    I suspect it *will* work but some potential gotchas to think about. Maybe you have a different idea for a portable monitor than me, dunno, but these USB powered things are what I think about.
