My first power cord lasted 5+ years, but now I'm on my third in as many months, and I'm getting no light unless I move the plug around or twist it while standing on one leg with my other foot out of a window. Sometimes a bad module on the board causes the malfunction. Alternate them in different slots in addition to trying each alone. One thing that hasn't been mentioned is to try the connection after removing one - then the other - memory modules. If not, there's a thought that it has a relationship to the charging system. What's the condition of your PRAM battery? When the system sleeps, does the white LED on the front pulsate? If so, it's good. However, you might replace that, as it's cheaper than the logic board. Even if it's solid, the DC-in card itself could have failed, but that doesn't happen often. On the female plug where the power adapter plugs into the side of the Powerbook, is it loose? This jack can become loose over time, separating from the DC-in card, which would prevent the power adapter from sending any juice. in what you've described, which is no power getting to the system using good power adapters, the DC-in card and logic board would be the two suspects. Unfortunately there's no automated test so you need to proceed with most likely causes.įirst, do you have another Powerbook available to you so you can confirm both power adapters are still working? Assuming they are good. There are 4 primary components in the power circuit: power adapter, DC-in card, battery, and logic board. I'm scared that it's some kind of internal power supply issue. I've had absolutely no luck with anything. I've tried a different battery, I've tried no battery at all, and several different combinations of new / old AC adaptor and new / old battery. A different AC adaptor successfully charged my machine to about 40%, and then the same thing happened again! Now, neither adaptors work with my PowerBook at all. and here's where the strange part comes in. Ever since then, my PowerBook hasn't charged at all, and it simply won't power up as it has no power at all. I plugged in the power cable, the green light on the connection itself stayed lit for about 3 seconds, then it faded out.

I rely on my PowerBook G4 every single day for my portable machine.Ī few days ago, I was running at a pretty low battery level (31%) so I decided to plug in the AC power and charge it up while using it. I have a pretty annoying problem that's effecting my day to day life in a big way.
