Haven't tried this myself, but instead of using a screwdriver, perhaps you could get a pair of tweezers (preferrably with some type of hooks at the ends) and use them to pull the screw towards you, and utilize the friction between the insert and the hinge to keep it in place while, carefully...

Interesting. Did you document it anywhere? The only solution I’ve come across this far is 3D printed replacements for the screw inserts. Regarding the longevity, both the front and back part of the housing showed cracks at around the same time, so I don’t think the old drilling fix affected it...

Thanks for your comments :)

The problem… A bit of background/history: Almost immediately after I purchased my PowerBook 170 back in 2001, two unfortunate accidents happened. After only using it once or twice, a crack in the insulation at the tip of the AC plug (a problem affecting the first version of PB1XX...

Oooh, that answers something I’ve been curious about for a long, long time! I frequently transfer stuff from OS X to my PowerBook, and as a result, hidden .DS_Store files are scattered all over the disk. Then whenever I run Norton Disk Doctor to check the system, it neatly puts together a list...

I'm still using beta 4 daily, and it's working great. Would be nice to get the speediness of beta 5, sans the bugs, but take your time. Good luck with the new house!

Finally got myself a profile picture after 8 years :)

Thank you for your thoughts. Since I wrote the post I have abandoned the idea of modifying the power bank's output, and instead plan on drawing power directly from the battery terminals (while still, hopefully, being able to rely on the BMS for safely charging the battery via USB). The main...

If voltage converters that provide a stable, linear conversion (where the output voltage equals the input voltage plus/minus a set amount) aren’t available, would it be possible electrically to somehow combine/offset the converted output voltage with the unconverted voltage? Anyone with...

My plan is to keep the power bank's circuity intact, to be able to conveniently charge the pack with standard USB chargers, and add a separate power converter for drawing power from the battery. I guess what I meant was unregulated power converters. Wikipedia's article on boost converters...

Thank you very much for your input! I haven't purchased any power bank yet, so I won't know for certain until I buy one and take it apart, but I'm aiming for lithium polymer for the greater energy density (and smaller volume). Also, I don't know, but my impression when looking around a bit on...

@sutekh, @360alaska, or anyone else with knowledge in lithium batteries and electronics, I’d love to you hear your thoughts!

After looking into the details of USB Battery Charging and USB Power Delivery, it seems like it would be a much too difficult task to be dealing with. While safe, it sort of takes the quick and easy out of the equation. So, would it be safe to leave the power bank’s circuity unmodified and...

Thanks, but what I want is a lithium based battery for my PowerBook, not a separate power bank to power it from :)

Thank you very much for your kind offer, but I would prefer a solution that’s as close to an off-the-shelf part as possible (original case (with my added port for charging), easy external charging, preferably through USB etc.). Also, I need more than 4000 mAh :) (especially if that’s at 3.7 V –...

Thanks, that’s valuable information. I actually thought about that aspect of it earlier but forgot to include it in the post. That might complicate things considerably, unless the USB output circuity can be bypassed easily and safely, or if output at higher currents can be enabled without data...

Hi all, I need a new battery for my PowerBook… Short background (feel free to skip): I built two batteries for my PowerBook 170 back in 2017 (briefly documented in this thread here and here) that I've been using regularly since then. However, all of a sudden at the end of 2020, they both...

That’s great. Take your time! (But not too long since I had to revert back to beta 4 because of the crashes and now miss the speed of beta 5 :D) By the way, after some further testing I noticed that some windows no longer are affected. Seems to be happening mostly to interface windows (such as...

Not that the display itself updates at 60 fps but guess the change lined up well with the frames :)
