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.
Look at the power indicator:
If it is not lit, no power is being supplied to the computer. If the computer has a battery, it may be low and unable to power the computer. Connect the AC adapter to recharge the battey pack and make sure the AC adapter is properly plugged into the computer and to the AC power outlet.
If the power indicator is lit, check if a non-bootable (non-system) disk or USB thumbdrive is in the computer. If so, remove it and press Ctrl + Alt + Del to restart the system.
Pressing F2 by itself is only used to enter the system's BIOS on startup. 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....

3. Backlight might be turned off. Press Fn and F6 to turn on the backlight.

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...
