MacBook Pro Question

I have something strange going on here with my 15" MBP Unibody

 

I connected my MBP 15" machine to an external FireWire 400 drive last night using a FireWire 800 to FireWire 400 cable. The drive was not plugged in, but the MBP was running. When I started the drive, the MBP shut down instantally. I could not start the laptop. I removed the FireWire drive, plugged the laptop in, it started up just fine, and I did my work, but did not get to connecting up the FireWire drive last night.

 

The machine would not start up at all this morning, but worked just fine with the power adapter connected. The battery showed a charge, but the machine would shut down immediatedly when I removed the power adapter. Interestingly, the LED charge lights on the side go dead when the power adapter is disconnected, but work just fine when connected.

 

I also recieved a notice that the PRAM battery was dead and the date and time needed to be reset.

 

I reset the SMC via the Apple instructions, and zapped the PRAM.

 

No joy.

 

When the laptop is plugged in, everything works fine, and the battery LED display shows a charge. The screen display shows a full charge as well.

 

When the power adapter is unplugged, nothing at all, no LED charge indicators at all.

 

Could my battery just have suddenly failed? It had a 4 plus hour battery life until 9:45 last night.

 

I checked the FireWire drive this afternoon, and it seems to work just fine.

 

Everything on the laptop seems to work fine when plugged in as well.

 

Any thoughts anyone?

A question about my Macbook Air's battery life...

I just purchased this Mac a couple of days go and, I haven't found any information to answer my question...

If I keep my Macbook Air (2012 model) on AC Power will it over charge the battery, or harm it in any way?

Because I know that my iPhone 4 has special charging instructions...like letting the battery drain completely until it shuts off, every 30 days. I found that on the apple support website very easily, not so much information on Macbook Airs though.

Anyway...That's basically all I wanted to ask...

                   Thank you to anyone who answers!

Question about items I found for my iBook that I don't know what to do with

As stated above, I have an iBook that I've had for several years and I cannot use it anymore to go online as routers aren't accepted in my household.  I recently found a plastic bag with a new USB cable, a phone line cable and a new battery Pegatron Model:PB013 with my computer things and I don't know what it is for since I never had occasion to use it.  Can anyone tell me what to do with these things?  I do know that they came with the iBook but at the time we bought it, we were never interested in what it is for.  If anyone can tell me the use for it, I would appreciate it and if there really isn't a use for these items, I will just throw them away.  I would love to be able to go online with my iBook but spouse doesn't believe in routers, says then others can get into your info even though I know that isn't true.  Any help would be appreciated.

MacBook charging question.

I received my new MacBook Air today and I couldn't see any charging instructions and the machine was already highly charged when delivered, so I have been using the laptop all evening and let it run out completely before plugging it in and allowing it to fully charge overnight. Does this seem like the right thing to do?

 

Also, when is it okay to recharge the laptop again? Do I have to use it to a low percentage before plugging it in, or can I use it to, say, 60% and then charge it again? I don't want to ruin my battery life! Thanks, guys.
