Macbook dies when disconnected from AC power

Question

I have a mid 2007 Macbook, and while its battery is not in fantastic shape, it was holding approximately 2 hours of charge running music and internet about a week ago.  In the past few days the battery has ceased to work at all.  I must have it continuously plugged in or the computer will shut off without warning.  It will also not turn on without being plugged in. Here is the battery information from the system profiler:Battery Information:  Battery Installed:    Yes  First low level warning:    No  Full Charge Capacity (mAh):    2555  Remaining Capacity (mAh):    2492  Amperage (mA):    0  Voltage (mV):    12484  Cycle Count:    562I have also checked the battery health by iStat pro, it reads at 51%.  I have done the SMC reset numerous times to no avail, and left it turned off overnight, unplugged.  The battery is fully charged. Any help would be appreciated.

If you have a MacBook with the removable battery you can get a new third party battery fairly cheap on eBay. Every MacBook from 2006 through Mid 2009 except the Late 2008 Aluminum Unibody and the Late 2009 and 2010 White Unibodies use the same battery.Black Batteries http://shop.ebay.com/i.html?_nkw&#x3D;macbook+black+battery&amp;_sacat&#x3D;0&amp;LH_BIN&#x3D;1&amp;_sop&#x3D;12 &amp;_dmpt&#x3D;Laptop_Batteries&amp;_odkw&#x3D;macbook+white+battery&amp;_osacat&#x3D;0&amp;_trksid&#x3D;p3286.c0. m 270.l1313White Batteries http://shop.ebay.com/i.html?_nkw&#x3D;macbook+white+battery&amp;_sacat&#x3D;0&amp;LH_BIN&#x3D;1&amp;_sop&#x3D;12 &amp;_dmpt&#x3D;Laptop_Batteries&amp;_odkw&#x3D;macbook+black+battery&amp;_osacat&#x3D;0&amp;_trksid&#x3D;p3286.c0. m 270.l1313Or for $129 from The Apple Store  http://store.apple.com/us/product/MA566LL/A?mco&#x3D;MTY3ODQ5OTY
