Hi, when I am charging the battery or using the iBook with the battery fitted in and still connecting to the A/C, the light on the power adapter plug sometimes goes off(I mean off, not green or orange, I think the power adapter is not actually working at this stage). if I pull the power adapter out of the wall socket then put it back in, the light turn on and start charging again(but sometimes only on for a short time). This has happened many times.

I tried to take the battery out and used the iBook power supplied by A/C only and it worked fine(the green light is always on).

I wonder any people here has the same problem and what the problem is, what can I do?

the spec of my iBook is G4 1GHz, 14", 256K L2 Cache, 640MB, 60G, AE.

thanks for your help

It's the power adapter's self-protection circuit tripping, which deactivates the adapter. It means your AC power is "dirty". At my old apartment, if I ran the adapter straight into the wall, it would deactivate. Putting my good surge protector in between fixed it. If a surge strip doesn't do it, get a UPS unit with a feature called "AVR" (Automatic Voltage Regulation), which cleans up the power. If you don't want the battery backup, but want even cleaner power, you can buy a device called a power conditioner, whose sole job it is to output squeaky clean power.
