Laptop booting up and then shutting off unexpectedly.
I have a Gateway laptop that was started this morning and unexpectedly shut off. Now, I can't start it. Lights come on and immediately shut off. Interestingly enough, an older laptop I had sitting around I decided to bot up in the meantime started to give problems now, too. It boots to Windows everytime but shuts off unexpectedly.

This sounds like the cpu fan assembly go to Gateway and enter the model in the support then download the system diagram so you can remove the casing it would take me forever to type the inst. once you have removed the cover put you hand over the cpu fan assembly and check for airflow

CHECK THE FANS! The biggest enemy to your laptop is HEAT! You just replaced the display it's very possible you inadvertently disconnected the cooling fan. Clean it while you have it apart dirt and dust prevent proper cooling
Is the Laptop Overheating? During intense game play your Laptop will Overheat if it's not getting sufficient air flow. Try cleaning the Fan, vents, heatsing with Compressed Air, Improve air flow through the Laptop, a Laptop Cooler is a option. Try shutting down unnecessary processes, I use freeware RAZER GAME BOOSTER, you configure what you want to shut down: http://www.razerzone.com/gamebooster Remember, Your machine usually shuts down for a good reason, it's trying to protect vital components. Overheating will fry the CPU, Graphics Adapter, etc.
First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty. Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.
When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.
When you dropped it you will have caused the Hard drive arm to contact the surface of the hard drive, damaging it.
Unfortunatly, it looks like it damaged the Boot files, Its worth a try with the recovery disc, you may need a new hard drive if it fails with the recovery disc
- buttons, especially the power button could be grounded. This needs replacement and repair. You will need to contact the manufacturer for support if warranty is still active. A technician needs to be there to replace some parts
- The reason why the computer went straight to diagnostic mode is because the power button could be grounded since it's turning on automatically when plugged and when the power was disconnected the system shuts down unexpectedly. Turning on a computer that experienced unexpected power loss may result to running in diagnostic mode
