Laptop Shuts Down Without Warning

 One fine day you're working on your Acer laptop. You have this important project that you need to finish and the deadline is fast approaching when all of a sudden the laptop shuts down without warning. You then wonder to yourself " Is it the battery? no it cant be cause I've already had it replaced recently." Fair enough. You even boot it on from Linux mint on a live USB and it still shuts down. What's the problem here? A couple of things could be causing your laptop to shut down.
Blue Screen of Death

If you're getting the deep blue sea(or Blue Screen of death) on your screen  your laptop is telling you to take a look at your hardware components or there could be a problem with your operating system. This suggests your laptop has blue screen errors. So long as these errors persists the operating system has to shut down and reboot for it to function. You're probably asking yourself, How do I fix this Blue Screen of Death?
Well, the process is a bit long. So pay attention.
First Perform a Clean Boot. You'll need a System Configuration Tool to perform this procedure
  • Click "Start" then "Run"
  • Type "MisConfig" and press 'Enter'
  • System Configuration opens
  • Under 'General Tab', select 'Startup Option'.
  • Tick the check box for ' Load Systems'  and uncheck the box for 'Load Startup items.'
  • Click'Apply' and then 'OK'
Delete Incorrect Registry Configurations:
You need to delete incorrect registry configurations.Outdated information in your system registry also triggers the blue screen. To fix this, you'll need to download  Regicleanse or System Mechanic    and scan the entire registry. Fix all the errors and when done reboot your laptop.
Change Startup Type of Specific Drivers

Certain drivers in your Device Manager should be changed  from 'Startup' to 'Demand' here is how.
  • Click 'Start' then 'Run'
  • Type ' DevMgmt.msc' and Press 'Enter'
  • Click "View' and "Show Devices"
  • Check whether the following devices are present: 
  • If they exist, click on then and select "Properties' option.
  • Click 'Driver Tab'
  • Select 'Demand' option from the 'Startup' drop down menu.
  • Click 'OK'.
Your Laptop Overheats

Because your laptop overheats  due to long hours of use, it needs to shut down to protect itself. Also, poor ventilation can also cause your laptop to overheat. Due to the strong electrical resistance of your laptop  components, your laptop can heat up to 170 degrees. The shutdown is necessary to protect the components from melt down. < To fix the the overheating problem, stand the back of the laptop up on a laptop stand and allow the air to flow under the laptop and around the batter. It should do enough to cool the laptop down. If you don't have a laptop stand, I suggest you purchase an adjustable  laptop stand.  to keep your laptop cool.

Automatically Shut Down
your laptop shuts down because you have configured it to automatically shut down  shut down in your default settings to conserve battery energy. This happens after several hours of inactivity. To avoid this inconvenience, check your power settings in control panel under "Hardware and Sound" and  remove this setting.

So there you have it.  follow these suggestions and you can prevent the scenario where your laptop shuts down without warning.
