  • Inside a MacBook Battery

    The battery on my MacBook is dying so I decided to just take it apart. You know, nothing stops my curiosity. I love taking things apart ever since young, though I wasn’t able to put most of them back together… last time. Hopefully, some things improved.

    Of course, I’ve paid for my curiosity with nasty shocks – just last week, I got a nasty zap from a flash capacitor inside my Canon Powershot A70. I got so pissed I just shorted the capacitor to get rid of the current in it. Some months ago, I got super freakin’ zapped by the household 240V AC current while taking apart a Sun PSU. The house tripped.

    Actually, this MacBook belongs to my sis, but she hated it so much so I swapped my laptop with hers, so technically, I’m taking apart her battery.

    Anyway, here’s the takeapart journey. Small torx screwdrivers are needed to remove all ten screws on both sides of the battery.

  • Environmentally Friendly Way to Discharge a Li-Po

    Earlier this evening, the air-con guy called me up and asked to meet up at my new house to discuss how we would love run the array of ugly thick gas pipes around the house. Since the electrical wirings are out, there’s no light in the house and we needed one.

    I keep an old Li-Po (Lithium Polymer) battery from my RC heli in the back of my car so I could use it with a 12V flourescent tube whenever the occassion requires. I’ve been using it for quite some time already and never had to recharge the 12V pack for almost a year.

    I brought the battery and flourescent light along to meet the air-con guy. We kept talking until the lights went out and drained the battery well beyond its safe minimum capacity and it puffed like a pillow.
