Dell Inspiron 1525 wont boot

Hi Terry,

I have a Dell Inspiron 1525. It was not booting, seemed like it had some issue with the motherboard. Got it changed. It worked fine for one day, then again the next day it was not booting.  Then I tried removing  the battery and kept the adapter on and it worked. Now is the battery faulty? Do I have to change that, or could it be some other issue?

Can you help?

Thanks in advance.

Linda.
