Okay so my laptop is dead for about three days. I cant figure out the cause, as i tested my charger with a test pen, and the light turns on (idk if the metal around the output conduct the electricity). Okay so i assume the charger is fine. Then i tried using test pen on motherboard power "jack" (i assume). It seems like there is power since some "fire" burst out a little. But my laptop wont turn on, the charging indicator also doesnt light up. I've tried something like hard reset though.

Help me, thanks.

But before it's working just fine. Does the voltage can dropped in sudden?

... and even if you get the right voltage open circuit, you can't be sure the PSU can still produce the power required when connected.. Maybe you can borrow a compatible known good PSU?
 


That is the second test, if the first one is not good, then he needs a new adapter, but until he knows that he has the correct voltage, we speculate about the problem.

I'll post the result once I get a multimeter. That could be the problem, as the charger is a 3rd party stuff. But if the voltage is not right, how it will affect the laptop? Like no indicator, or any sign?

And I'm using laptop, how can I use a PSU..

So I've checked on the charger, right the charger was faulty. But I've tried another charger, the computer can light up and turned on, but there's no display, even with a monitor. Is the motherboard is the problem, since there was spark when I tested it with a testpen. Also the fan doesnt spin.
 
The way I troubleshoot the problem is with what I know from your laptop, since you don't tell me what is the make and model of laptop you have, and you don't know the voltage from the adapter, I can't tell you what is defective with your laptop.

Oh I'm sorry i forgot to mention of that. The model is HP Mini 110-1006TU. The charger voltant should be correct, 19V, 30W as I tried with the original part from HP, and from different retailer. And the light turns on, while my own charger doesnt show up anything.
