How to tell if battery dead or problem with logic board?

My early 2011 Macbook Pro recognizes an attached battery but isn't charging it. Per CoconutBattery:

Current Charge: 0 mAh

Maximum Charge: 3716 mAh

Design Capacity: 6900 mAh (53.9%)

Mfg Date: 2011-02-10

Load Cycles: 89

OS X Battery Status: Poor

Battery Temp: 33.6

Charging with 0.0 Watts

Battery State: Discharging

Before I go buy a new battery, is there anyway I can tell if the logic board is damaged and not supplying the battery with power? It runs on the 85w magsafe adapter alone but at significantly reduced clock speed. I tried a SMC reset. Thanks

I noticed that these three orange components appear to have been overheated. There appears to be very minimal corrosion in a couple other places on the port side of the board. Should I try to soak/brush it in alcohol as a first step?

The battery is 50% worn out well with half capacity left it says. I think the battery is still okay to use but just won't last as long as a good one.

Does the magsafe charger show a orange light or a green light? Could be liquid damage issue on the board.

I can't get an orange light. I removed the logic board but couldn't observe any obvious liquid damage. I'm wondering if there are any places to test with a multimeter to see if the charging circuit is damaged. Also, the battery may have just sat too long uncharged for the computer to deal with it. In that case, any way to jumpstart it, so to speak?

Before you do anything else, take it to an ASP and request that they run the test for this issue, you may end up with a free logic board replacement:

Thanks for the tip, I bought this used and discovered that the computer has been disassembled before. It's missing some screws and such. Where does apple draw the line on user tinkered stuff before voiding the warranty?

An ASP Auhorized Service Provider is going to cut you a lot more slack on something like this than Apple will.
