Hi! I am having a problem with my Dell Inspiron 5150 laptop. The laptop was brought to me because it didn't start. It tried to boot up on me once but then died completely. So I ordered a new motherboard and when it arrive I have had the same problem. I have two light battery and something else (can't look at it now) flash every 5 seconds when the laptop is plugged in to the wall. when I insert a battery only one flashes and it is amber hue. I replaced almost all parts on it so I don't know what it can be. I heard that some laptops can't start without a battery but I wanted to consult with you before a make another purchase. Thank you!
