Power for the PowerBook 100

Hi everyone

I own a PowerBook 100 but it's power adapter has a leaked capacitor. Still trying to get the PowerBook back working i bought another power adapter. However it has got the same issues.

This weekend i've been experimenting with a universal adapter. I could get it at 7V and 4,0A. The original adapter gives output of 7,5V and 2,0A, afraid of melting something i didn't plug it in.

Any ideas on how to get the PowerBook 100 back alive?

regards

more amps is fine, the system will only "take" what it needs

where you get into trouble is when the system is taking more than the supply can provide, which causes a meltdown of the power supply

Be careful about using an adapter that is not regulated (ie, keeps the voltage at a precise level). If you use an unregulated adapter that can't supply enough current (amps), it can go into over-voltage and burn out the device.

You should be fine at 7V regulated and 4A available current though. I doubt the 0.5 V difference will break anything; might have difficulty charging an internal battery if you even have one - I would run without just in case. IMHO and YMMV, at your own risk, etc.
