Inspiron 15 -5558 won't power on
I suspect a bad battery but I have no history as it's a friend's laptop.
When plugged into the AC adapter, the adapter light comes on, but no indication that anything is charging (no lights on the laptop at all). If the power button is pressed, with or without the adapter plugged in, the power light and keyboard lights briefly (1 sec), a fan starts to spin, and the system turns off again.
Alternate power adapters have no different effect.

If it's the battery, remove that (or disconnect it), hold the power button for 30 sec. and then plug in the adapter. Try powering up on AC only.
If it will, it's the battery. If it won't, replace the mainboard.
