You didn't post the Make, Model of Laptop or the OS you are using. I'll use a Win 7 solution. Boot the Laptop, open the Control Panel, select Power Options, set to High Performance, select Change Plan Settings, set SLEEP to Never, select Change Advanced Power settings, go through the settings , set SLEEP and Hibernate to Never, Power buttons and Lid to shut down. Always shut down and unplug your laptop when not in use to prevent damage from power surges and possible Fire hazard IF the battery malfunctions. A reboot every day will reset the computer.
When you turn on the laptop and get a black screen, does it sound like the computer is still running(are any lights lit up etc) ? If so, then you possibly have a bad video display. I would highly recommend visiting a repair shop or contacting the manufacturer of our laptop for service repairs.
If the laptop is plugged up to any other display, or TV , unplug it and reboot.
If it does not sound/look like your laptop is actually turning on then you may have a power issue. You can try some of the following tips to see if it resolves your issue. -Leave the laptop charging for 10 minutes then try and turn it on. It may not be charged up enough. -Try a new power cable -Try a new battery -Try a different wall to charge the laptop.
The following applies to Acer Laptops. You did not specify the brand of laptop you had. If your laptop is not Acer, the specific keys mentioned may be different and you should adjust accordingly.
If the power indicator is lit but nothing appears on the screen - The computer's power management system automatically blanks the screen to save power. Press any key to turn the display on. If pressing any key does not turn the display back on, check the following.... 1. The brightness level might be too low. Press Fn and the right cursor key to increase brightness level 2. Display device might be set to an external monitor. Press Fn and F5 to toggle to the internal display 3. Backlight might be turned off. Press Fn and F6 to turn on the backlight. 4. If the Sleep indicator is lit, the computer is in Sleep mode. Press & release power button to resume.
please check if you will see the Power On Self Test (POST), wherein this test is like a DOS prompt wherein the Specifications of Intel is specified. But if you don't see anything on the screen, try to remove the cables and battery after you turn off the laptop. Then press and hold the power button for 8 secs. Reinsert the cables and battery back to the laptop and turned on the laptop. If no display appeared, call Acer to repair your laptop. Motherboard problem is the main reason why...
In fact, that is the troublshooting technique when your computer does not boot up, insert the recovery disk and allow it to reload.

if the display did not lit and power indicator is flashing rapidly------you will have short circuit in speakers cables -----turn it off and remove short circuit cable-------or you have block in ventilation holes---------turn power off and leave it to cool down and remove anything block ventilation holes---and turn it on again after cooling---------another solution-------on screen display is set to off on system setup------turn it to on in system setup.
