Hi there and welcome
Can you do the following please
Remove the power cable and the battery from the Laptop
Then hold the power button down for 60 seconds then release.
Once done, connect the battery and power cable and then try to turn the Laptop on.
Let me know please if it then starts
Can you tell me which model laptop you have please?
ok, this is one of the few models with a non removable battery
Thats ok, just skip the step of removing the battery please.
Let me know the results
you mean you have already remove the power and held the power button down for 60 seconds?
Are any of the lights showing on it at all?
And how old is it?
It is the internal chipset on the motherboard that has faulted. The power supply is ok as the lights still show (from the battery as well as the cable).
A corrupted firmware can cause this. But we have ruled this out by trying to hard reset it.
I am really sorry about this and you are going to have to return the laptop to have the motherboard replaced. It will be covered by the warranty and the replacement will be done at no cost to you but it has t be replaced
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
ok, do you feel comfortable dismantling it? As there is one more step you can do yourself that they would do under warranty for you.
