I Just brought Dell Laptop last week( January 20, 2017), at first it I was stuck on Dell Logo i tried many solution to solve it just like removing the battery , unpluging the AC adaptor , hold the power button for 30 seconds , after that I plugged the battery in and the AC adapter, but still it's not working. And now, My Laptop will not turn on, when i press the power button the led light flash but the screen has no display, its only black :( How can i repair this ? What the problem with it ? Thanks.
