MacBook Pro Charging Issues

[robertd]

Hey guys. I have the first generation MacBook Pro that they brought out with the Intels, so it's maybe 5 or so years old. I have never had any issues but about a 6 months ago I did a battery replacement, well the new battery has never seemed to hold much of a charge and I am constantly informed to service battery (I assumed it was a glitch of some sort since the battery was newer). My charger plugs in and charges for a few minutes but occasionally the light will dim and almost go out, it then stops delivering a charge. The display also shows 40%+ battery charge but my MacBook will randomly go to sleep and when I wake the display it says 0% left.

Is this a battery issue or maybe a charger issue or is there something more serious happening with my computer? Any help you guys could give would be extremely appreciated!

sounds like you got a bad battery. If it charges initially, then the issue isn't with the charger, but with the battery.

After the light goes out on the magsafe power, if you unplug the battery, does the computer shut off?

I never thought of trying to charge without the battery in. When I remove the battery the computer still works when plugged in. Guess it is the battery. Is there any way to check the serial number on Apple to if I am still within warranty or do I need to take it to my store?
