RE: My Inspiron 15 won't turn on
Hi Fried Mind,
Inspiron 15 comes in 7 different variants. Please share the exact system model.
You may try removing the battery and turning on the system with only the adapter connected.
Also, try running the diagnostics by following the steps below:
Disconnect the battery from the system, hold down the power button and connect the AC adapter with the power button pressed to see if the diagnostics begin.
Keep me posted with the results. I will be glad to assist you further.
