MacBook Pro 15" Unibody Battery Indicator Light

I recently bought a used MacBook Pro "Core 2 Duo" 2.4 15" (Unibody) Late 2008 and have replaced several parts with more coming soon .... One thing I've noticed is that when I connect the charger the Battery Indicator LED's on the ports side light up briefly then go out completely.

I've never owned a MacBook Pro before with this feature and not sure if they're suppose to stay on ? and change as the battery charges ?

So if anyone who has this model or has owned this model could give me some insight if something is not functioning the way it should that would be great -

The battery checker LED's do in fact light up when you plug in the MagSafe power adapter. They will go out within a few seconds if the battery is fully charged, otherwise they will stay on until the battery is charged.

This is normal!

All the LED's light up for a few seconds no matter what the battery percentage is and Do Not come on again even with a full charge ( battery life cycle is 70% ) so from what you're telling me this is not normal.


Just so we are talking about the same things here run this app: Coconutbattery this is a free app that will give you a better picture of your systems battery. take a screen shot of its display and post it in your question (edit it)


How so? The charge effects the LED's as you use the system on battery alone. Slowly the LED's will not light starting from the right end working back. Run your system for a while on battery alone so the charge is about 20% used based on the menu bar's battery level value. Then press the battery checker button on the left of the LED bar (round silver depression).
