My laptop is not working anymore… I was a bit gambling, suddenly the sound stopped and 1 minute later he crashed and he hissed funny 3 seconds. Now he does not drive up… Previously, not even the standby light went on, now it works again. When I press the power switch, it does not start up and hisses very quietly for a few seconds. I do not have a battery in it, so it can't be there, it is not overheated either.
If it hissed, something broke. Remote diagnostics are usually not possible.
The crash most likely will have broken something in the laptop. This can be a component or something else… In such a case you can't do much anymore. Build the hard drive and the RAM, the rest as it is you can throw only then in the electronic waste. Is not nice to hear that I already know. But unfortunately the laptops are so built today. Too bad.
