Hi, i have a Problem with my Dell Inspiron 7520 LA-8241P Mainboard.
When i start it, all LED's turns on but the display is black.
Shortly after starting I noticed a click on the mainboard but don't know where it came from.
I have tested it with the i5 and after the click the laptop goes off but with the i7 the laptop stays on after the click .
The Dell Inspiron 7520 supports the i7
What I've already done:
- start without RAM and it beeps 2 times
- start without bios battery and it beeps 5 times
- Press D on start, but show nothing, the display remains black
- CPU changed (i5-3210M to i7-3632QM) -> no improvement
- flash new BIOS (original BIOS A10 from Dell) -> no improvement
- RAM changed -> no improvement
- Display changed -> no improvement
- the Battery is charging
I don't know what the problem is and my technical understanding is very limited.
Has someone ever had the same or a similar problem and have a solution?
