T60电源指示灯一直闪

特此请教本人的IBM T60购买才不到一年，平时使用时也特别注意，基本上都是拔下电池使用，昨天突然发现电源指示灯一直在闪，拔掉充电器以后电脑无法开机。请问是怎么回事呀？

在Power Manager>Battery Information 里面有如下信息，
Irreparable damage to the battery has been detected. Replace the battery with a new one.Your battery can only store 54% of its original full charge capacity.90W ac adapter is attached.

程序的问题吧，死机只是程序挂掉吧？
