It turned off out of nowhere when I was playing a game, then it simple died all it does is this weird blink!

I have:

- Removed the RAM and put it back again.

- Pressed the power buttom for 60s and waited a few minutes.

- Pressed the battery buttom behind the notebook with a clip for 5 seconds and waited a few minutes.

- Removed the battery and put it back again.

- Pressed the power for 60s without the battery.

- Cried a lot

The notebook has around a year of use, mostly for 3d modeling, rendering and gaming.

The temperature was hot I don't know exactly how much tho.

I had undervolted around -0.115v.

It happened once a month or two ago but did not stopped working like now.

Its possible that the undervolt causes any problems?

What is the exact model? example g3-572-58vh. Is it still under warranty? Does this model have this button?

No warranty.
No buttom

I would start by disconnecting all hardware and testing each one individually. I would also check out this video:

But remember it may not be the same problem!

Thanks for trying to help... I am not good with computers, was hoping for an easy fix, unlucky I guess, gonna try to find someone to repair it...

I would try to reset the battery:

I already did this
I also tried again to:

- Remove the battery, click power 60 seconds, replug it and try to turn the computer on.
*Same result just a LED blink

- Remove the battery, plugged the charger, tried to turn the computer on.
*No answer from the computer not even the LED

Makes me even more worried!
(The charge was 100% when the computer turned of out of nowhere)

I would start by checking if the power adapter provides 19v with a multimeter. I would also press some keys on the keyboard and without releasing them, I would press the power button, to check if the notebook turns on when pressing several keys.

I dont have a multimeter to check, but, if that was the problem what would be the solution?

Notebook blink once as always even when lots of keys are pressed.

I tried plugging my fan table and it turns on for a few secs when I turn on the notebook, but it shuts down right after with the notebook

*I was using the right USB slots, I tried with the left one (the 3.0 port I think, idk) and it keeps the table fan on, if I try to use all the notebook energy in the battery would that change anything?
