Safe to plug-in on 110VAC 400 Hertz?

Question

Will my laptop suffer damage if I plug it into a 110 Volt AC 400 Hertz constant frequency outlet?

Answer 1

It might, but probably not immediately. If you feel that the voltage adapter is getting unusually warm, unplug it.

You see, in most cases, transformers don't like to be plugged into a lower frequency source. But they are designed for a specific frequency.

I recommend against it.

Answer 2

I will say yes, it will damage it! Mainly because of your power supply. The Computer actually operates on DC like a car battery, that why it will work with your Battery Installed when you portable. What the power supply do is convert the AC into DC. Hertz is the amount of times AC goes from Positive to Negative in a cycle (Hertz). This increased speed from 60 to 400 Hertz may over heat the components of your power supply (Being designed for 60 Hertz) and burn it out. This my opinion and I may be wrong.

Answer 3

YES! You will damage your laptop. The transformer at least is external, but the bridge rectifier, the components that convert AC to DC are usually internal, and yours were not designed to filter out 400 Hz. You'll wind up feeding excessive amounts of AC into the circuitry.

My real worry, and I don't have enough experience with the newer batteries to know, is what this will do to your on-board battery.

Answer 4

Now most power supplies to Laptops are made to convert to much and to little. Depending on what Laptop, IBM is one that makes to converter in the power box. Just keep a look at the black box and if its get very warm unplug it, use you battery, and the later plug it back up to charge you batt.
