Hello everyone.
I'm trying to put in place the notebook in question.
It 'a friend of mine, unfortunately crashed and you are no longer on again.
I already did the usual tests, without battery, reset CMOS.
No signs of life.
I need some advice Electronic / Computer.
Now I totally disassembled, I unplugged all devices, type keyboard, dvd player, wireless card.
I'm looking at some different voltages, power supply marks 19,69 Volt.
The power button is connected to the motherboard via a flat cable.
If I measure the button shows me 2.5 Volt. According to you okay?
What other evidence could do.
Thank you in advance.
