i got a dell 1545 from a buddy of mine that told me it didnt work, quickly i noticed the dc port was messed up and ordered the part. it came in today and i installed it but when i plugged my battery into the laptop nothing happened. the battery light just blinks white... i took it apart and looked to see if all my connections were still together and from what i can see it looks like they are. if anyone has any pointers please let me know. or if yall have something i can look for cause nothing comes on when i press the power button. when i installed my brother in-laws battery into it, the light stayed on but still nothing happened. im not sure what could be wrong with it.
