Remove the battery from the unit and allow it sit for a couple of minutes then plug in the unit to power and see if it somes up. Removing battery and power often unlocks a unit. make sure hibernation is not causing problem. Once it comes up successfully, power off and reinstall the battery, try again. Some times a failed/failing battery can lock things

Check the color of the power light on the monitor (screen). If it is orange, that means you're getting no signal from the CPU to the monitor. If that's the case, check the signal cable going from the CPU to the monitor to make sure it hasn't been disconnected.
So there is not so much as a BIOS message on screen? Any beeps? If there is no life at all, you have a CPU/motherboard failure. This may be direct or indirect (e.g. no power to MoBo). Check your connections. Otherwise, your boot device may not be operating. This is usually a dead or disconnected HDD. Check that it is plugged in. Does it get warm? Can you feel any vibrations from it? It should spin even if your cpu is dead but MoBo is alive.
hi,check the CPU of your computer if it is booting properly.you can try to push the caps lock of the key board pressing the keyboard once the LED light indicator lights up then press again the light will turn off .This means that the CPU boots up and functioning properly.Check the data cable connecting the CPU and the monitor there must be a broken line there you can replace the cable or you can re insert the cable a loose connection can cause the problem.IF all are good and still same problem try to re insert the video card from the main board make sure to turn of the power before removing the video card...try this solution and post back if nothing happens after doing these solutions..good luck!
If you mean a constant beeping, open the case and see if the CPU fan is running, check also that the heatsink is firmly attached to the board, this noise usually points to a n overheating CPU, if you get no activity on screen,it is because there is no signal being sent to the monitor. Do not operate the computer until you have checked the fan is working, you need to establish if there is power getting to the fan by testing with a multimeter on the motherboard cpu fan pins. If you are getting power, replace the fan, worthwhile removing and regreasing the CPU and making sure it is firmly in place.
If there still is no signal, replace CPU, but also try a different graphics card (faulty video will give 9 beeps).
It could be your monitor is fine. It simply goes to a cycle when its turned on and does not detect any signal coming from your CPU, it simply goes on standby mode (hence the darker image and orange/blinking light.) have you checked the computer (CPU) part?
First Check the power cable of ur monitor whether power is coming or not..
Then remove signal cable (which is connect the cpu) and then switch one the power, check whether any msg is coming in screen.(like no signal or no connection) if it comes means u want to check the cpu or else their is problem in ur monitor..
Connect the another monitor with ur cpu.Whether ur cpu is working properly..
