MacBook goes to sleep without warning at above 15%

[jplg842]

Hello.
I started getting this problem a while ago.
While im on battery and it reaches around 15-20% my macbook will turn off without warning.
when i press the button of the battery one green light flashes and stays on (meaning the battery is not completely drained).

I have a Late 2006 white 2GHz Macbook
373 cycles and health of 70%

i have not been able to calibrate the battery since it doesnt drain, instead the laptop shuts off.

What should i do??

Thanks

There have been other postings on this same problem. Search and you shall find the battery is the culprit. Go see Mr. Apple for a replacement.
