I have a Satellite U405D - S2852. Last night, I tried to shut it down as normal, but it froze on the shutdown screen. I gave up, closed the lid and went to sleep. In the middle of the night, it was making hard drive spinning noises. I got up, opened the laptop and tried to switch it off. It wouldn't switch off. The noise was keeping me awake, so I took out the battery.
In the morning, I tried to switch on the laptop. The power comes on, but that's it. Not even the Toshiba logo. Can't hear the normal starting up sounds.
Any idea what's wrong with it? Is the motherboard fried? Is there any way I can fix the problem at home? I've tried the usual combinations of taking out the battery, holding down the power button, etc. No luck.
Thank you for your reply. I tried holding down the power button, but it didn't work.
There's a new development. I tried switching it on and off several times throughout the day. One time, it miraculously came on and booted up, just like normal. It was as if there was nothing wrong with it. I used it for a couple of hours without any problems. Then I went out. When I got back, it was dead again, the same as this morning.
Does that mean the motherboard is fine? Is it just a loose connection somewhere?
I wish I knew what brought it back to life. I didn't do anything different.
