Hi, I have a problem with my laptop now. Itís a Toshiba Satellite L300D-40. I have received it 2 days ago I did some Microsoft updates. Then I was on it for a while then I got off it. I went back on a couple of hours later and I lifted the monitor and nothing. I not even shut it down. I only moved the mouse. The charger was also cold. The battery lid was green and not orange. My son has the same laptop and I tried the battery of that charger but nothing happened. Then again I put the battery in my laptop and I pressed the button of power. I have 5 lid lights on the front and 3 are green, the power lid and picture of a clock lid and the battery lid are on. The charger was warm when the battery lid goes green to orange. When I hear something going on in the laptop and the 3 ledís on. The HDD led doesnít come on. The screen is black. The before mentioned that work stay on they donít stop at all after a few minutes .I tried removing the battery and holding the power button down for 30 sec. then 45 sec. I put the battery back in and still a black screen. They said on the internet to try the battery removal and press the power button. Just because the battery led is green and the charger is warm I donít know if it could be one or the other with a problem. But I tried my sons and it didnít work. Am now thinking itís the central processing unit or motherboard. Any suggestions I could try .Any special buttons to press on the key board when it boots. Is there such a thing as a hard boot? I even put in the Toshiba recovery disks and they didnít work. I tried a secondary monitor thinking the screen was bad and nothing came on the monitor. There isnít even any beep codes. Not too much on the internet.
