Hello. I have a Macbook Pro (Late 2008 model) Battery is a A1281. The last month of time, my batterys lenght has been to around 30 minutes, which isnt really such a long time, compared to the 4-5 hours it had to begin with. Now three days ago, it didnt want to start at all, so i've charged it for three days now and even covered it in a blanket, but it still wont boot. I've tried doing what it says on apples website (Taking out the battery and megsafe - pressing power button for 5 secs, and set everything back together) and the resetting where i hav to press (left) shift + ctrl + cmd + power for 10 seconds.. that didnt work neither. Now on my old macbook white i could run my macbook without a battery in, but only the charger. - can the macbook pro do the same thing, or does it require a battery at all time? Cus if it cant, then i can try buying a new battery, but if it can then its something else then the battery. I really appreciate you guys taking a look at this for me - i would rather not end up paying 2-300 bucks to get an apple guy to check it out, and then be told i need a new 200 buck battery.
