I recently got my hands on a G3 iBook 500 MHz which is in really good condition except for some things I noticed:

1) The harddrive is probably dying - really noisy and I would like to swap it for an ssd. I have seen several adapters on amazon but which are compatible? They all seem to have some sort of IDE to SATA bridge onboard.

2) I would like to hook up an external display but I am not sure which adapter to buy - is Mini DVI right?

3) When I installed MacOS 9.22 on this machine it got really, really hot. Is it normal for these iBooks? I thought about re-applying thermal paste but I fear breaking the plastics in the process. My MacBook from 2006 is already crumbling away.

4) How do you think about buying a new battery these days? I guess these do not sell well and are probably years old if you buy new. I am intrigued to repack the battery with new cells - has anyone ever done this before successfully?

I run one of the red board IDE-to-mSATA adapters on my clamshell iBook 466 (I no longer remember the brand, if there was one, but it was spendier than a cheaper, green board adapter which was faulty from the outset). Mind you, I bought that five years ago when mSATA was the dominant, small form factor blade SSDs (in terms of price and availability). These days, obviously, the m.2 SATA form factor is most common and prices for those are lower, in most cases, than mSATA stock still out there.

The IDE-to-m.2 adapters I use in my two PowerBook G4s are the generic ones (from eBay/Amazon/Aliexpress) which come with either a white or black 2.5-inch HDD-style case. They’ve worked flawlessly and uneventfully for me since 2019. Those boards are also green, but bear no relationship to the green ICE-to-mSATA adapter I tried back in 2018.

2) I would like to hook up an external display but I am not sure which adapter to buy - is Mini DVI right?

The dongle you need is the mini-VGA-to-VGA adapter 603-0607/922-4554. As you probably already know, the mini-VGA-out on that iBook mirrors what’s on the main display — not unlike the mirror feature on my clamshell predecessor (which uses a different method for composite-out).


3) When I installed MacOS 9.22 on this machine it got really, really hot. Is it normal for these iBooks? I thought about re-applying thermal paste but I fear breaking the plastics in the process. My MacBook from 2006 is already crumbling away.

The ice iBook G3s were the first iBooks to have a fan in them. Even so, all the designed components were packed into a tight case (something the clamshell design didn’t have to struggle with).

First thing first, you’ll need to look into whether the fan inside your is still functional and/or is powering on at a certain temperature threshold. Whatever the case, if it hasn’t been done before, it’ll need a clean-out. But chances are also probably likely that it no longer freely spins when power is sent to it (as a lot of these older fans are prone to do).

Applying fresh thermal paste is going to need to happen anyway, especially if you’re disassembling it for a thorough clean-out/tune-up.


4) How do you think about buying a new battery these days? I guess these do not sell well and are probably years old if you buy new. I am intrigued to repack the battery with new cells - has anyone ever done this before successfully?

If you can find a working battery, go for it. There’s a company on places like eBay whose “brand” is to show the aftermarker battery and generic box against a Photoshop-yellow background. Having bought one of these for my clamshell iBook, just before their prices nearly quadrupled in 2019, I would avoid them at all costs. My battery began to have failing cells about two/three months after purchase, and the final cells failed within six months.

In 2019, I bought eight 18650 lithium cells to attempt a cell re-pack. I ended up having the eighth getting very close to thermal runaway as I finished the connections. Fortunately, that didn’t occur, but the polarity on that cell completely reversed and was, effectively, ruined. I never bothered after that because, frankly, that’s a lot of energy to be dealing with should something go sideways, and I don’t think I can come close to replicating mass-production conditions (including the arc-weld which typically affixes the series plates between cells) in the confines of my home work space. So I have seven good, basically unused cells sitting around with nothing to do and little desire to try that again anytime soon.

That said, if the idea of re-packing seems like a bit too much to try on a lark, you might want to keep your eye on old iBook G4 12-inch models which people are disposing on your local used web sites (CL, etc.), as I think those batteries can be used in the iBook G3 ice/opaque models. At this point, you’d be better off salvaging used iBook batteries from those used laptops, as some will have batteries with good serviceable life left in them. This route, of course, may look aesthetically off, as the G4 batteries are of the opaque white plastic finish, but it should give you portability.

One positive thing, though: iBooks don’t, in the absence of a working battery, downclock the way PowerBook G4 models of the time period (the models with an L3 cache) do in the absence of a working battery, so even if you need to carry a power adapter, you’d be getting full power out of your 500MHz PPC750CXe CPU.

Let us know how everything goes. :)
 
@B S Magnet has done a fine job of covering it, just a few added notes;

1) The harddrive is probably dying - really noisy and I would like to swap it for an ssd. I have seen several adapters on amazon but which are compatible? They all seem to have some sort of IDE to SATA bridge onboard.
We had a thread going on the forum where we were posting many different working configurations that might help steer you in the right direction:

The red board mentioned was a Lindy brand, which I have used in a few PowerPC Macs, but also went by other brands including "Addonics" model AD25MSD / ADMS25IDE (according to my records).

As mentioned, this is a few years out of date now, so finding the exact same combinations might be tricky - I don't have any experience adapting m.2 to PATA, but there may be others here who can confirm a working configuration on their PowerPC Macs.

Just be mindful that buying a 2.5" SATA SSD + a SATA->PATA adapter likely won't physically fit inside the iBook unless you open up the SSD to remove the board/components and discard it's outer case, which is usually majority empty space.

2) I would like to hook up an external display but I am not sure which adapter to buy - is Mini DVI right?
As per the reply above, mirroring is the only option. So that external display (via mini-VGA > VGA) will only be able to be driven up to 1024x768 resolution. There is some discussion around the iBook G3 and "extended desktop" hacks here:
https://forums.macrumors.com/threads/ibook-g3-500-dual-usb-mirror-mode-hack.2211760/

3) When I installed MacOS 9.22 on this machine it got really, really hot. Is it normal for these iBooks? I thought about re-applying thermal paste but I fear breaking the plastics in the process. My MacBook from 2006 is already crumbling away.

Where do you feel the heat coming from? I find my iBook G3 500MHz runs real cool, the fan has never come on (or I didn't notice it) and I have not re-applied the thermals on this one - I assume it probably used a thermal pad rather than paste as many G3s did at the time.

If the majority of heat is at the palm rest (left side) then it is likely that noisy hard drive spindle is cooking up due to corrosion and/or dried out lubrication. Replacing the hard drive (with either an SSD or a healthy HDD) will improve this dramatically.

If you are getting [excessive] heat from the right side palm rest then stop what you're doing and dispose of that battery before it becomes a fire hazard!

Also just on the plastics - the 2006 MacBooks were notorious for cracking/crumbling even under regular use. The iBooks had a bit more of the right mix to stand the test of time. These things were touted as literally bullet proof when first marketed by Apple -- or maybe I'm making that up. I can't find any references to this or my memories crossed over with something else there o_O

Also, you'll need to take a few dozen steps to open up the iBook just to replace the failing drive, so while you're in there it is always a good idea to investigate the thermal cooling situation (replace worn out components, test the fan spins and re-lubricate, blow the dust out, etc)

4) How do you think about buying a new battery these days? I guess these do not sell well and are probably years old if you buy new. I am intrigued to repack the battery with new cells - has anyone ever done this before successfully?

Those iBook G4 12" batteries will work perfectly fine in the G3s. They are a different shade of white and style of plastic, but they fit and work as expected.

You can re-pack the cells if you're adventurous. I've done this for a clamshell iBook G3 with success and those replaced cells are still working great 5 years down the track.

I might be the culprit because I'd previously raved about the anecdote of the Panasonic CF-M34 Toughbook that stopped a bullet when an infantryman in the 82nd Airborne came under fire in Iraq. :oops:

Can confirm! I've got a 500 MHz iBook with a battery from a G4 and it works perfectly, I get around 4 hours of use from it!

Yeah, mine too. The hard drive actually produces more heat than the processor and I can feel it is the hottest area underneath to the touch. The fan on mine also never spins up either.
Although I do have a 500 MHz PowerBook G4 and for some reason that thing gets so hot it burns, even when the fan is on (which is very loud). I even replaced the thermal paste and pads and it didn't change much.

I think it might have been Steve Jobs saying they're made from polycarbonate, "just like crash helmets and bullet proof vests" - clever marketing like titanium laptops "just like spy planes..." :)

My Powerbook is made from Aluminium, whoops, sorry - Aluminum..."just like sweet wrappers..." :D

Amusing, since the clamshell was made of the same polycarbonate case material.

drat, FOILED AGAIN…
 
Thanks for all your kind answers!

The heat is located on the right side of the palm rest. I only installed OS9 last night and I rarely felt a laptop that hot.
As I do not know for how long it ran that hot I won't stress this out any longer.
It came to my attention that many of these models died prematurely due to heat.

Replacing the thermal paste and the harddrive is something I want to carry out in one setting to avoid opening the laptop too many times. I looked at the ifixit guide with like 40 steps... Apple has come a long way since then.

I will look out for a used battery. New ones are not on sale anywhere near me.

That's how it survived Phil jumping off a platform while holding it. ;)

The 500MHz models don't really have the GPU failures the later ones did, but it's still a good idea to reduce heat where possible. And yes, I loathe opening iBooks so I get wanting to do it all at once. The 12" PowerBook G4 may have a lot of screws but I'll take that teardown over an iBook any day. 😄

Did you use same capacity cells? I've wanted to replace mine on my laptops with high capacity ones and double up the batteries on my Lombard to shoot for a 24 hour battery life but I've heard from someone on Tinker Different that that might not work and they'd be unrecognized by the pack's firmware...​

What a way to spend an afternoon. This was one of the least enjoyable teardowns I had.
Later models were really way easier to get into but now I have a working 120 GB SSD in my little iBook.

Does anyone else notice that older iFixit guides are really not that good after all?
 

1. In comparison to more recent ones the images are quite low-res
2. there is less focus on details
3. there are quite a few mistakes or important details left out

Sure it differs from entry to entry but in general the quality has improved a lot

Ok, I was just curious about your experiences.

Thanks for replying. :)
