I have power but it doesn´t turn on
I tried hard reset, nothing, i have the light of power on, but when i press the power button nothing happens....
These laptops are known for GPU failure, as are many laptops from this time period; I'm surprised it lasted as long as it did.
Hook the laptop up to an external monitor with VGA, since you'll need this to rule out the GPU. These are known to lock up under any sort of load when they fail, so what you want to do is try loading the OS normally. In my experience the bad GPU ones fall flat on their face here as the high level driver kicks in and causes it to lock up. If it locks up before it gets to the login screen, the GPU has failed. If it loads the login screen, the internal display has failed. In most cases, it's caused by the GPU.
If the GPU is bad, you can boot into Safe Mode for data recovery purposes most of the time. Copy the data off of the laptop and then wipe or destroy the hard drives. Do not bother repairing this, since the problem cannot be repaired. Repairs will work, but it will always die again.
