Either your graphics cards has failed, your screen has failed or the brightness has been turned all the way down.
check and see if you have a display port on your laptop (it is usually a blue 15 pin connector) and plug it into an external monitor and boot your system... if that works, your graphics card is ok.. either your screen died or the brightness is all the way down.
on some laptops, there is a button on the top row that allows you to toggle between the laptop display and an external monitor... you could try that too.
the reboot also leads me to believe that maybe the mainboard failed or the power circuit into the mainboard...

No power on vizio E371VL


Vizio TV model E371VL turned on ok and had tv show on ch.4.
Turned on the DVD player and put movie dvd in and closed tray.
We have done thhis numerous of times and never had a problem.
This time " HDMI " was showing on top right of black screen,
then " No Signal " came up on screen, then went completely black screen. Called Vizio, they had me power off and unplug set.
Push and Hold power button on TV for 30 sec. to reset.
Replug set and Vizio (lighted) on lower front of set lighted normally dull orange. Pushed power button on remote and when set did not come on, then push main power button on side of TV. Nothing, no White " Vizio " from orange light. Is this a power supply (0500-0412-1020) problem ? Thanks, Sidney (sidneysites@yahoo.com)

It sounds like your dishwasher might be locked. You unlock the dishwasher by pressing the "heated dry" button for three secs. and then releasing it, that should do it.

It wont turn on


Sounds like water damage but try this......... 1) press the * and # and Power button all at once - if the screen fires up with a black screen and some info - then you can flash the phone and hopefully recover it; 2. If the above works - you need to find a flash file and the software to flash it with Good Luck
