I left the room returned 30 minutes later and I observe my inspiron B130 was off. I pushed the power button and nothing happened. I unplugged and then Replugged then also nothing happened. Then I removed battery. And put it back in but then also nothing happened. Then I left it for all night and after night when I try to on It again this morning then also nothing happened. I Have tried a call to Dell to ask if this is usual or a security feature. They are not responding properly. Any suggestions from anyone, so thanks.
