So, I find myself without the AC adapter for my laptop and I need power.

My adapter is rated 19.5v 4.7a.

I have an adapter from an older machine (same manufacturer), rated 19.5v 3a.

The physical connection to the laptop is the same.

Will I damage the laptop and/or the battery if I use this lower rated adapter?

Or will the battery simply charge slower?

Insufficient information to tell you anything certain.

There is a good possibility you would damage the lower power adapter as it gets overloaded.
If the adapter fails it could damage the computer.
