Laptops Powered by AA Batteries (Seriously)

And some of them run an impressively long time on a single set of Double-A's.

December 03, 2023

If you’ve ever thought to yourself, “Gee, I sure do wish I could run my laptop on AA batteries”… boy are you in luck.

What follows is a list of laptops (or things that are very laptop-like) that can be powered entirely on replaceable AA batteries.

Atari ST Book

Released in 1991, the Atari ST Book was an absolute marvel. Slim (only 1.4” thick), light (4.2 lbs), and plenty powerful for a portable of the day (4MB of RAM, 120 MB HD).

Plus… the darn thing ran for 10 hours on 7 AA batteries (a rechargeable battery pack was also available).

TRS-80 Model 100

Released way back in 1983, the TRS-80 Model 100 is a pretty limited machine by today’s standards (especially compared to the likes of the Atari ST Book). 24k of memory. 240x64 display. But it also has a big, desktop style keyboard that is an absolute joy to type on and a built-in BASIC.

And it runs for a full 20 hours (I’ve done better than that with mine) off of just 4 AA’s.

To put that in comparison, the originally Gameboy also used 4 AA’s… and tended to get 15 hours (give or take) of play time.

HP OmniBook 300

Ah, the OmniBook line. Small. Light. With that adorable little “pop out mouse”.

The OmniBook 300, released in 1994, had a 386 CPUunder the hood, a monochrome VGA display and could run for up to 9 hours off of 4 AA batteries (when using the Flash storage model… the spinning hard drive model could manage around 5+ hours).

There were also 486-based models, including the HP OmniBook 425, that also ran off 4 AA batteries.

HP 200LX

Ok. So the HP 200LX (and the 100LX and 95LX) are technically “palmtops”. But they run a full, regular version of MS-DOS 5.0, are powered by an Intel x86 CPU (the 80186), and can have up to 4 MB of RAM. Making them a pretty noteworthy DOS portable.

Powered by two AA batteries and clocking in at a whopping 40 hours of battery life. I have one of these. Can confirm that the battery life is astoundingly good.

Alphasmart Dana

The Dana is a fascinating machine. A slab form factor, touch screen, PalmOS device will a full keyboard. Running PalmOS 4.1.2, with a super wide 560x160 display, 16 MB of memory… this is a true “PalmOS laptop”. Even has USB, SD card slots and (in later revision) WiFi. No joke.

And 40 hours of battery life (with the backlight off, 20+ with backlight turned on) via only 3 AA batteries.

Gecko EduBook

Here’s a somewhat more modern entry: The 2009 Gecko EduBook.

A “netbook” class laptop, shipping with Windows XP, juiced up by 8 AA batteries. Those eight batteries bring in only around 4 hours of battery life (a whole heaping helping less than everything else on this list).

But, hey. It’s running XP. And can probably run Linux. On AA's. Which is pretty nifty.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Those in power with openSUSE make it clear they will not allow me anywhere near anything related to the openSUSE project. Ever. For any reason.

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

A Eulogy For Omarchy - Sunday Laptop Rebuild Stream

Last Tuesday, I tried to put Omarchy on my daily driver laptop. After six days of fighting with it, I'm quitting.

This is the THIRD TIME I've tried to make Omarchy a thing for me, and all three times, I've had nothing but struggle. So, now, we're going back to Manjaro. But before I do, I'll spend a little time experimenting with other distros, live on camera, unscripted. Just for the gawkers.

The 100x Architect: Why the "Vibe Coding" Argument is a Dangerous Coping Mechanism

I hear it constantly from my fellow nerds: “I’m not worried. Non-coders ‘vibe coding’ AI slop will never be a threat to my job.”

You’re 100% right. Vibe-coded slop isn't the threat. The threat is top-talent developers who also master GenAI tools.

While the skeptics are busy mocking juniors for generating buggy Todo apps, they are missing the real shift: the veterans with 40 years of patterns in their heads who are using GenAI as a 10x multiplier.

The math is simple: 10x1 is 10. 10x10 is 100.

If you are a talented dev (a 10), and you refuse to use the multiplier, you aren't "staying pure"—you’re just being out-scaled by the people who have your skills AND scale themselves with GenAI.

A Field Report from the 100x Front:

In two recent projects—one for a paying client and one for a friend—I built in a few hours by myself what would have traditionally taken a small team a couple of weeks...

Lunduke Journal Week In Review - Jan 16th, 2025

Whew! It’s been another wild week for Tech News!

Here’s a crazy stat for ya:

We are currently 16 days into 2026, and The Lunduke Journal has already recorded 19 shows (17 of which have been published on every platform, and 2 others to be published this weekend everywhere… but are already available via the MP4 download page). And that’s with taking New Year’s Day off (and getting the flu this week).

It’s a heck of a lot of Tech News, to be sure.

Lunduke’s Top Stories for the Week

If you only have time to watch a few of shows, I recommend these 3 as being the most interesting (or important… or just… strange) from the last week:

In other words: A pretty gosh-darned crazy week for Linux.

(Those links are to Lunduke.Substack.com, but you can watch all of those shows on any other platform. As always.)

Other Tidbits of Awesomeness

A few other notes on this, most excellent, Friday!

The Lunduke Journal started publishing to TikTok this week. Why? Who knows! Because we can!
If you are a subscriber you can get access to the MP4 download pages (as well as the official forum) by following instructions on the Perks Page.
Reminder: Lifetime Subscriptions are only $89 this month.
So, you know, you want one of those.

And, with that, I leave you with a screenshot of the MP4 listing of the shows so far in 2026. Bonkers.

Lunduke's Lifetime Subscriber Wall 3 is almost full!

Holy moly.

This afternoon I sat down to update the 3rd Lunduke Journal Lifetime Subscriber wall — adding in all of you who sent in requests over the last week or so.

And, boy howdy, were there a lot of you! So many, in fact, that the 3rd Lifetime Wall only has room for around 6 or 7 more names (depending on the name lengths)! That’s crazy!

If you want to make it onto “The Lunduke Journal Lifetime Subscriber” Wall number 3… send me an email (bryan at lunduke.com) with the way you would like your name to be displayed.

Or, if you’re not already a Lifetime Subscriber, remedy that for $89. (Which, you know, is a pretty gosh darned good value.) … Then send me that email requesting to be added to the wall.

Once Wall 3 is full, we’ll start in on Wall number 4 (that’s nuts). At the current rate, I expect Wall 4 to debut this week.

And, as always, thank you for your support. Whatever kind of subscription you have, it is deeply appreciated. Monthly, Yearly, or Lifetime. All are amazing. You make The Lunduke Journal possible.

You rule.

Lunduke Out Sick Tomorrow

I’ve got the flu (or something else yucky) and need to take the day off tomorrow.

But I don’t really have a normal “boss” to email. Heck, all of you are sort of like my collective boss.

So I’m emailing you:

Boss, *cough cough* Lunduke is out sick tomorrow.

Which means no new shows on Wednesday. Hoping to rest up and be back with new shows on Thursday.

If you’ve missed any shows over the last few weeks, now’s a good chance to catch up.

And feel free to grab one of those fancy-shmancy $89 Lifetime Subscriptions while you’re at it. That won’t make my flu go away any faster… but it definitely won’t hurt.

Unrelated note: Buying stock in Nyquil might not be a bad idea. I think I’m about to increase their profits.
