I forget to tell you that when I put the charger pc do a beep and turn on automatically I remove the battery and put charger, it’s same (pc do a beep and turn on automatically ) and I forget something about battery light yesterday it was red which means is very low, so I put it for long time and it is now white which means the battery is full or more than 20% (I think it’s charging) I can see that the battery is not the problem() I have thinkpad T430 can I use this battery to test the second pc any other idea?
