I have a IBM Thinkpad 2888-4BU. About 4 mths ago I was experiencing problems with my laptop. This is what happened. I would try to cut it on and it cam on for about 2 secs and cut of and the indicator lights (battery,caps, and power etc.)Just started to blink and made a clicking noise and then stopped about 2 secs later. Everytime I would go to cut it on it would do that and after about 3 times it wouldnt cut on and it just made that blinking noise. About 3 mths ago it wouldnt cutt on at all or make the blinking and the noise. When i plug it up to try to charge it now the charging light wouldnt comme on. My sister has the smae computer and i tried to put her battery in mine and it still wouldnt work.
