It is common problem in dell inspiron 1525 laptop for battery charging due to DS-2 LIO BOARD is defective. which show Plugged in not charging. Also charger may be defective.
Laptop was working like as a Desktop. I was facing same problem in my laptop. On contact from DELL service center, representative say that main board is defective. Same will be change to resolve the problem but I searched on net found the reason that DS2 LIO BOARD was defective.
I change my DS2 lio board in my laptop and also replace battery charger. Now my laptop is working good
this is the manufacturing defect in DS-2 LIO BOARD of dell inspiron 1525 model laptop. I am not suggest to purchase dell inspiron 1525 model. Dell should change the DS2 LIO BOARD FREE of COST. IF any one required DS2 LIO BOARD may contact me.
