    Thanks for this video!
    I just picked up a first gen from a thrift shop here for 10$. Battery light goes orange when plugged in. Pressing power turns on the top left light and the power led green. I'm going to try your fix but I'm also suspecting the screen/battery are broken.
    Thanks VERY much for your video!!
    What would be the command you'd actually be sending through the serial port to the laptop if I get it connected to fix the clock? Or was it more for diagnosis?

    7:26 Remember, this machine was meant to be cheap, durable and easy to fix when it broke. Also it was sized for a child to use, not an adult.

      yes, sure, and also it may be relatively durable in hot and dusty real-world environments, ...

    I still use my XO-1.5 now and then. I just hate that you can't view Flash content anymore (as far as i know).

      Nice! Did Flash ever work on those? I was never really a fan of Flash, I guess if you really wanted to, you could use swfdoc t2sde.org/packages/swfdec to continue using it w/ OpenSource, ..!

    Hey dude how did you connect to the actual J1 serial socket on the board? What is that piece you are using and where can we find one? I have the AdaFruit FTDI friend ready to go but it's unclear how I'm supposed to connect to the tiny pins on the board

      I said this in the video ;-) the matching micro connector, or like me: an old Apple iBook speaker cable that also fits after trimming it's plastic a little bit. Getting the matching micro jack thing is probably easier, more straight forward, or also go thru your tinkering spare parts boxes and see if you find something fitting ;-)

    Interesting, I didn’t know it had a serial port for such diagnostic use.

    • @renerebe
      @renerebe  6 ปีที่แล้ว

      yeah, still most modern devices have diagnostic serial ports, often unpopulated on the PCB, from router, modems, IoT, cars, you name it ;-)

    I just got two of these with this issue. They were purchased by the organization I work for probably a decade or more ago (most likely the buy one donate one option). Would replacing just the clock battery get them to boot, or do I need to do the serial connection as well? Also, since you're magically turned on unexpectedly, should I leave them plugged in and powered on and see if they eventually get enough charge to the RTC? I do want to try to update the firmware at some point, but don't have a soldering kit (or skills - never soldered anything before) so I'm researching options to get a mostly plug and play kit running. I've got a RPi B+ that I've never used for anything other than as a little general purpose computer so maybe I can interface that with these machines?

      I only have one OLPC so I have no other data points. The instruction on their website clearly stated somewhere, that charming and waiting will not make this problem disappear. Yet it looks for me it somehow did. I mean you could try, probably, I guess, but it might simply not have an effect. You do not really need soldering skills though, just disassemble, and plug in the serial connection into the micro connector. Best avoid the overpriced (~$100) ready made solutions for OLPC, a serial dongle and this micro connector thing should cost less than $10.

      @@renerebe Good to know, :) I'm gong to take one of them apart and see what I'm up against. I've seen a couple fairly cheap kits (under $20) and new batteries look to be around $2 or $3, Thanks for the reply!

    Hello! I have an old xo laptop with a crack screen because my stupid little brother cracked it! I'm an young adult now and I received this laptop in elementary school. Is there a way to extract the old videos and information off of it?

    I head of that glitch when I got mine, the first thing I did when getting it was updating the firmware and the OS.
    Hope this doesn't happen to me.

      Cool what are you doing with it, still using it?

    PS: I would recommend doing this DIY like sown in the vide, with any regular serial adapter, and not spend over 120$ for this, e.g. on eBay: www.ebay.com/itm/OLPC-XO-1-0-One-Laptop-Per-Child-Serial-Adapter-Fix-Bricked-XO-Laptops-Not-Boot/261077483054?hash=item3cc96e3e2e%3Ag%3AIV8AAOxyNSVSQUlH
