Ok, here’s the story. I own a Toshiba Satellite A350 laptop for a few years. As every night, laptop was on, I press the power button making it go into hibernate and then pull out the plug (battery is out, since it is always on cable and it might save the battery)

The next day, I plug in the adapter, press the power button and nothing happens. Literally nothing. Black screen, not a single sound .. nothing. All I can see is the indication light that the adapter is plugged in, which lights up.

I searched the internet (using another PC, duh ) and found lots of similar issues with Toshiba laptops. Main solution seems to be holding the power button for 30 second, putting the battery in and restarting it. None of these methods help.

I took the laptop apart, checked (and disconnected) the CMOS battery. Checked the power button, which is working, cleaned everything.

Here’s the weird thing: I have an USB optical mouse and a keyboard connected. I noticed that –besides the indication of the adapter- the red light of my mouse is on all the time and also the indication lights (caps lock, num lock) of my keyboard can be switched on. So there seems to be power on my USB as soon as I connect my adapter.

Hope anyone can help, because I ran out of options. Two friends looked into it, no one has a clue.
