Laptop Comes On With A Black Screen. How Do I Fix This.
After replacing a cracked screen on my Acer laptop 7250-3821, I turned it on. I went to the yahoo site and suddenly a blue screen popped up then it went black. I turned the laptop back on and got the black screen again. What is the cause of this problem and how do I fix this problem.

- Press and hold the power button until your laptop is forced to turn off
- Unplug the laptop from the charger
- Remove the battery
- Press and hold the power button for 30 sec to drain all power left on the laptop.
