Acer V3-572g problems

[Markosgcx]

I have this laptop with
Motherboard: z5wah la-b162p
Processor: i7-4500U
ram: 16gb
GPU: nvidia geforce 840m

When i turn on the laptop the fan goes slow, with no display at all and i cant make sure if the internal keyboard works.
I tried an external keyboard and the lights works accordingly.
Whats the problem of the motherboard ? Its a "new" motherboard from a factory located in china. It should work.
Is it a bios error ? or an ec error ?

Hi! If you have two memory strips, then try running the motherboard with one.

Tried that.
It turned on when I pressed the power button but no light on display and the fan stopped. 200€ product.

On the bios battery, how many volts? Try to unsolder it and briefly close the contacts on the motherboard. Try connecting an external monitor.

Re: Acer V3-572g problems

The bios battery is off the motherboard due to customs reasons. Tried to connect to an external monitor but again no signal.

We need to put the battery on. Some motherboards don't start without it.

I had the old motherboard it works without it. My mind tells me the problem is elsewhere but I fail to understand.

In the other motherboard same model it worked turned on and could get into bios system. Here this motherboard just don’t cooperate

Clearly a malfunction of the motherboard. We need a deeper diagnosis.

Now here I stop because I don’t actually own a technical workspace. I just want to know what’s going on with it.
I will communicate to change the motherboard with a new one.
TMT z5wah la-b162p sucks.

Hello guys. I wanted to share these facts with this computer.
Never put a different screen and always check your cables flex. I went it to a technician. He managed to run the computer. Problem was that it wasn’t posting, lcd flex burnt and screen heave for the motherboard.
Thank you guys for the support. Everything solved
