G4 powerbook adapter plugs/tips

I have had the unfortunate repetitive occasion of seeing the wiring going into the older style G4 powerbook tips gradually get loosened and then break off. I successfully resoldered one of them, but I have at least two others, one of which I tried to break off the plastic cap but then couldn't have possibly rewired it, even though I thought I had the pattern for wire connection points down before doing so.
Is there anyone selling these old G4 plugs, preferably with wires coming out of them? It seems unlikely, but a proper wiring guide or diagram might also be helpful, as I am still doing this on the fly, i.e getting sparks in the dark!
Seems obvious this is one reason Apple switched to a different connector design!!
I still can't understand why there are two wires inside the wire, and sometimes a shielding strand which is like a bald man's last locks. Finally, take note of the fact that the connector plugs look suspiciously like phono plugs/RCA connectors...don't suppose I should use one of those, eh?

Hi
You should try the Mac PowerBook G4 forum - or -
may be http://www.macfixit.com/ might be able to help.
Yes the old plug is bad. NO You can't use a RCA-plug.

Powerbook G4 won't charge battery or run with power adapter plugged in.

My Titanium Powerbook G4 will not charge the battery or run with the power adapter plugged in. When plugged in the power adapter doesn't change to amber showing its charging. Instead it has a green light that flashes off and on. I thought it was a defective power adapter but when its plugged in to another powerbook its seems to be working properly. I reset the PMU but that didn't help. I have been unable to find anything that would tell me what a flashing green means.
Powerbook Titanium G4 Mac OS X (10.3.9)

Hi, Marshall. With no power being supplied to the Mac for several months, not only has your main battery gone flat (and may never again be able to take a charge), but your internal backup battery has also gone flat. A Tibook with a dead backup battery generally will not start up at all, even with AC power connected.
Try this: remove the main battery and leave the AC power adapter connected overnight in an attempt to recharge the backup battery. If the Powerbook won't start in the morning under AC power, the backup battery is shot, has lost the ability to be charged, and must be replaced.
If the PB starts up in the morning on AC power, set the date and time correctly, shut the computer down, insert the main battery, and allow 48 hours with AC power connected in an attempt to charge the main battery. Then disconnect the AC adapter and try to start up under battery power. If that doesn't work, and no lights or only one flashing light appear when you press the power-indicator button on the battery, you'll have to replace the main battery.

Which adapter plug in World Travel Adapter Kit is right for Argentina?

My father in law is off to Argentina with his PowerBook in tow. We know it can handle the voltage down there but I don't know which world adapter plug he needs as it's not listed as one of the choices in the World Travel Adapter Kit. Nothing for South America is listed in the kit, for that matter. Any ideas?
Thanks much,
Jake

Jake,
Check out this site for the type of connector and voltage used in Argentina (and everywhere else for that matter).
http://kropla.com/electric2.htm
It is the "Australian" type that he needs.
If he hasn't already bought Apple's adapter kit I'd recommend he just buy a travel adapter in Argentina, or in the Airport departure lounge on the way out - they only cost a couple of bucks and will work just fine. When I moved from Canada to the UK nearly two years ago I thought the Apple kit was overpriced - spent £2 on the relevant travel adapter that I'm still using.
Good luck,
Gareth

IPod AC Adapters + Foreign adapter plugs

I will be traveling to France in the next couple of weeks and was wondering if I could attach an adapter plug to the prongs of my American iPod AC adapter and be able to use it, or would it just fizzle out? This could be a very stupid question but I wanted to make sure.
Windows XP

Not really a reply, but piggybacking on the topic raised in this thread:
I'm travelling to India next week, and discovered - to my surprise -
that the World Travel Adapter Kit (WTAK) doesn't have anything that
works with India's electrical plug standard. In the dim recesses of my
memory, I recall that someone had ferretted out the name of the OEM
supplier of Apple's Powerbook AC adapter, and discovered an aftermarket
supplier of various plugs that fit them, much like the ones in the
WTAK, but with support for other electrical standards - which might
even iinclude India's.
And yes, I realize I can stick a converter plug on the end of standard
Edison cable and handle it that way, but I'll be moving around a lot,
and having a dedicated plug on the end of the Apple adapter cube will
be much slicker.
Can anyone help? The usual search engines have come up empty. I recall
the supplier being Asian, with an odd name, but that's probably not
much help. The irony is that one search took me to the Apple Store in
Indai's listing for the WTAK, which of course does not help anyone
either in India or travelling there at all.
Thanks in advance.

Power Adapter Plug Keeps Disconnecting on 1.67Ghz ***

I constantly have to re-push in my power adapter plug into the
Powerbook 1.67 Ghz. It seems as though the socket in the Powerbook just wants to squeeze the male part of the adapter back out again and again. I have 2 power adapters that this happens with, so I am almost certain it's the female socket on the Powerbook itself.
Has anybody been able to get Apple to cover this problem under warranty?

If you are still under warranty I would suggest you contact AppleCare regarding your issue. Every case is unique so just because one person may have gotten it fixed, or has been refused, does not necessarily mean this will fillow in all cases.

Can I charge my ipod classic in Germany with the same usb wall charger I use in the USA, by plugging it directly into the correct adapter plug? Or do I need a power converter/transformer?

I will be in Germany for a year. I want to take my ipod classic and charge it with a usb wall charger, like I do here in the USA. Can I simply use the correct wall adapter plug for Germany, or must I use a power converter/transformer in between?

It should work as long as the prongs adapter are adapted to the outlet configuration.

Hp pavillion dv9700 won't start with Ac adapter plugged in

Dear all,
I have a 3 year old hp pavillion dv9700. The problem is that the computer won't turn on when i remove the batteries and leave the Ac adapter plugged in. The led that indicates that the adapter is plugged in is on, so that means that the adapter is working fine. But to be sure, I used another Ac adapter from another dv9700.
The next thought I had that the problem might be the Ac jacket( that is connected to the motherboard ). So I dismantled 2 dv9700 laptops (one is mine, the otherone from a friend, which is by the way working fine), and toke out the Ac jacket from the laptop that was working oke and replaced it with mine(whIch wasn't booting with the Ac adapter). And still the same problem. So now I am able to say that there is something wrong with thE motherboard.
When ever I plug in a battery that is not empty, the laptop starts up normally. The other thing that noticed is that whenever I plug in the battery the led of the Ac jacket turns on (not full bright, but somewhat dimmed). This doesn't happen normally. That means that there is somewhere a short circuit on the motherboard.
I have looked all over the internet, but wasn't able to find someone who had the same problem as me, or a solution for it.
Ps. It has nothing to do with the video card, because if that was the case, it wouldn't even start with the batteries.
Already thanks, kdeo2k

Which adapter plug from the Apple Worldwide Adapter Kit should I use for travel with MacAir to Czechoslovakia and Hungary?

Traveling to Czechoslovakia and Hungary and puirchased the Apple Worldwide Adapter Kit. I'm confused about which adapter plug to use with my MacAir. What does the correct plug look like?
Thanks

Here is the link to the adapter kit on the Apple website:
http://store.apple.com/us/product/MB974ZM/B/apple-world-travel-adapter-kit
This may or may not suit your needs but I suggest that you visit an Apple store and take a look at the kit yourself. With the information from prior link, you should know exactly what to look for.

Power adapter plugged or unplugged when using an external display?

Is it safe to keep ac adapter plugged into notebook all the time?

I have been consistently using a Pavilion DV6-1230 US notebook for 5 years almost always with the ac adapter plugged in. I have replaced the battery once. I was told yesterday that this is not a good idea because it can lead to a shorter battery life and hardware issues. We are buying a new computer and want to know what is the recommended practice for using ac power with a notebook. Is always connected OK? Or do we shut the computer down at the end of the day? Should the power plug be removed from the outlet? Appreciate suggestions and recommendations on best practice in this case.

Hi: It is not a good idea to leave the power cord connected with the battery in the PC continuously. You should disconnect the power source at least once a month even if you don't move the notebook, run the notebook as needed, and let the battery drain down until you get the low battery warning. Then charge it back up. Here is a helpful HP guide for prolonging battery life... http://support.hp.com/us-en/document/c01297640

HT4124 can I keep the magsafe power adapter plugged in to computer all the time?

Can I keep the magsafe power adapter plugged in to my computer from the power source at all times?

it is ok to keep it in all the time, BUT at least once a month let it run the battery down to 10-15% then do a full recharge.

Why can I not load pictures from a micro SD 64gb using scan disk adapter plugged into an Apple iPad camera connection kit. I have the iPhoto app but pictures not being seen on iPad. So incredibly frustrating. Apple please fix this.

Do you have a smaller capacity micro SD card to try? I seem to remember from past posts that users were having problems with cards larger than 32GB, however, Apple's page doesn't mention this.

Macbook won't sleep with power adapter plugged in

Hi,
My Macbook has stopped going to sleep if the power adapter is plugged in.
I have the power adapter energy setting to sleep after 30 minutes. When I got the Macbook (about a month ago) the thing would sleep until I pressed the spacebar.
Now, the screen blanks but otherwise the Mac remains awake.
If I close the lid the Mac immediately goes to sleep.
I have reset the SMU but this didn't fix the problem. I also checked disk permissions and verified the disk in Disk Utility - all good.
Suggestions?
Thanks,
John

my MacBook has also stopped going to sleep with the power adapter plugged in or when using battery power, unless I close the lid. Did you ever figure out the problem? Did you try calling Apple Care?
thanks,
Liz
