Quick update. I opened up the 2400 which was a substantial task. The hard disk had been upgraded at some stage in the past an was not touching its heatsink. Also the thermal past…

The flickering is a sign of insufficient voltage. Either the battery is marginal, or the power regulator board has a problem. The crashing could also be due to power instability. …

Using OF commands, after amending the settings for thermal-info I got the fan to turn on straight after booting, by setting them to 01010200 00000000 01010200 00000000. With the o…

I've got a 2400c spec'd very similarly to yours. My NUpwr is the 240MHz variety. Anywho, I couldn't say anything for sure about the first issue. It could be that something's aging…

If it crashes with intensive programs maybe it's overheating?

Hi everyone. I have a Powerbook 2400 with a few problems. I wonder if any of you knowledgeable people can help me out? My machine works pretty well. It has a NUPower G3 upgrade, …

Hi All, I've been delving around in open firmware on my Pismo to see if I can control the internal fan, or at least set a better temp. for it to come on at. In the device tree I'…

Am trying to revive a dead 2400c/180 in the next week or three. As detailed on this page, among a handful of others in English, there are some dozen or more fuses in the innards o…

Very, very rare indeed, so you might reasonably conclude that the weight and stiffness are much more valuable to you in stabilizing your laptop than a tiny, tiny risk of fire from …

Thermal runaway is kind of rare considering how many batteries are out there and how many combusted.

I think the filler is useful to give the laptop increased mechanical stiffness and better balance. And the primary hazard is with charged cells. However uncharged batteries still…

So basically the cells are dead and the memory manager will not let the unit charge at all. There is no problem then using the battery as a space filler in the laptop (which is the…

Thanks for that, Wally. It underscores how much more there is to fear from mistreated lithium cells than from the LHC.

Upon battery insertion the battery manager board, if working, momentarily test charges the cells and looks for approximately 3V= If this is not met charging is disallowed and the…

I recently got in 3 dead wallstreet batteries (2 Apple made and one 3rd party). One of the Apple batteries charges in like a few minutes to 4 lights and will not boot a machine. I …

Just an FYI, the 30 gig that I yanked from the Vaio is an IBM Travelstar, and it's deathly silent. Unless it's reading or writing, you'd think this thing had an SSD in it. Add that…

As long as the first partition on the disk is less than 4GB, SCSI Disk Mode will work on the pre-G3 PowerBooks with high-capacity hard drives. Of course, only that first partition …

At this stage, I would recommend a CF card on an internal 2.5" IDE adapter if you really want flash storage. Click to expand... In case you use an internal CF-IDE adapter for t…

I've had no luck using a PCMCIA ATA Flash card to boot a Powerbook (G3 Lombard). I don't know at this point whether it's a bad card or a fundamental problem with that card type. …

If you do _not_ need the SCSI target disk mode but want to have plenty of storage, get a recent hdd that produces not too much noise. Avoid the old travelstar models. Consider to b…

1400s can't use internal SCSI drives, only ATA/IDE. They can take any size up to 136GB, but yes, if you use anything larger than 4GB, SCSI Disk Mode (target mode) will result in d…

I have 120GB in my Lombard and my sister's Pismo has a 40GB yanked from a mac Mini. Both are PC compatible drives.

As far as PowerBooks go, so long as they're IDE inside, you can use any bloody drive you like. I yanked the 30 gigger in my Pismo right now out of an old Sony lappy
