Any possible way to fix this issue with my PowerBook G4 battery? It holds charge, but the capacity is reported wrong, therefore the gauge percentage is not correct. I tried charging and discharging it few times with no improvement. Thanks!

I can also confirm that I repaired multiple LCIIs that all did this. Every time the problem were capacitors. They are just bad. And the first one that I came across with this problem was back in 2011, so at that time the machine was "merely" 19 years old, this is the same age now a G5 iMac or a...

Those are standard DA7052A (TDA7052A in SOIC-8 package) from what I can see. I see they have them on Aliexpress and eBay...

Update: it has been now running flawlessly for last 6 hours. I only still need to sort out the battery issue. I was thinking of putting a CR2032 there, I think it will work, despite being 3V instead of 4.5V. P.S. For recapping, I used 25V rated caps for 12V rails and 16V rated caps for 5V...

Hello everyone, I just (almost) finished restoring Performa 630 which I got for €25 few years ago. Previous owner presumably found it in some abandoned building, along with a painted black Mac 512K which I also got. He cleaned it a bit and removed the leaky battery, but didn't have the right...

I am interested if anyone has managed to obtain the schematics (or perhaps a boardview) for G3 series of PowerBooks. I repaired lots of MacBooks and other Apple and non-Apple hardware in the last 10 years or so, and I do have every schematic for every Apple laptop from the PowerBook G4 on. As...

Very nice! I went through same steps on my PB 140 and 160 :) Mine had failing hinge mounts on the LCD cover, which was fixed with 3D printed bracket

I know, I recapped mine years ago, when I started collecting these PBs. But reccaping is easy compared to polarizer replacement... If NOS one was stored in original packaging, and never used, then it will be most likely still fine for few more years. Also I found that NOS units usually don't...

Thanks, you are welcome :) I wouldn't risk it as I don't know if it will work, nor if it needs to be oriented in a specific way (like 90 or 45 degrees off axis). Also I found some NOS LCD panels for about $100 few months ago (don't know if they still have it), so I'd rather take full panel...

Thanks, but it is awfully expensive. Almost $70 (incl. shipping) for just one small sheet of film... and I might need two of them in the end which doubles the price

Of the keyboard? :) It looks like it wasn't painted, I will make some photos soon

I have 4 laptops of similar vintage, all developed vinegar syndrome. All of them have passive matrix of course, so that means they are just for parts now if there is no source of STN film. Too bad, as I modded them with CF-IDE adapters, rebuilt 2 batteries with fresh NiMH cells, recapped some...

I got a Methoxypropanol, and it works great, but it would work the best if I had enough to fully submerge the plastics in it... Sadly it cost me $25 to get just 0.2L of it. I managed to clean the keyboard almost 100%, now I need to tackle the system unit. Anyways, the four screws that hold the...

I used some citrus cleaner at first and it took the paint off quite nicely after few minutes of soaking. But it was still quite slow, and the textured parts were stubborn. I then tried using a Acrysol, which is said to be good at removing acrylics and other stuff. It was even better than the...

iMac G5 may work "fine" with multiple blown (bulging) capacitors, or might fail to POST or exhibit problems with just one defective capacitor. My iMac G5 (17-inch, 1st version) has 2 bulging capacitors on the mainboard and it works fine. I reccaped the PSU (also very important on those!) about...

That's true. But I would really like to see how bad the original caps were ESR wise. If that was a eMac (the one with known capacitor disease) or iMac G5, then a full recap (including the PSU) would be totally in order. I had iMac G5s that didn't boot into OS (just froze) that had just one...

My condolences. Btw, why did you attempt to do a full recap anyways? Were there any problems that looked like there were bad capacitors? I deal with 70 year old radios and TVs sometimes, and I almost always replace just one cap and then test. I only do a full recap on few sets that I had...

No replies? Is vinegar syndrome so rare after all? I found another two laptops with vinegar syndrome, one of my favorite 486 laptops ever made - Compaq Contura Aero 425. And one much newer, a Compaq Armada E500, from 2000! That one was still fine just 6 months ago. I guess the defect isn't that...

Here, some photos:

My PowerBook 160 sadly developed a vinegar syndrome after being stored for bit more than 2 years. Other similar aged PowerBooks in my collection are still fine, also being stored for same amount. I opened it and found out that the panel is Sharp LM64P58. I saw few videos about replacing the...
