Blue Screen On Start
All system operations become terminated during start-up because of blue screen
Overheating
A device that is overheating can lead to a system failure and a blue screen. Ensure that your cooling fans are always in a proper working condition.
Outdated Drivers
Whenever you update Windows OS, your old drivers can conflict with the new OS and even create blue screen errors. A malfunctioning driver can cause various issues. To fix this, you have to completely reinstall or update your drivers.
Keyboard/Keys Not Responding
The keys on your keyboard appear to be faulty or sticky
Keys Are Stuck In Place
If the keys on the keyboard are difficult to press, it's possible that in situations like this, there might be something physical such as debris or dirt stuck in between the keys. To fix this, remove the keys and make sure that nothing is stuck below them. You then can wipe the area with a cloth dampened with alcohol preferably isopropyl (avoid bleach). You never want to clean your keyboards with a soaked cloth, as that can damage the hardware that lies underneath the keys.
Keyboard Wont Type
If your keyboard is locked, you might have turned on the filter keys feature accidentally. Hold down the right shift key for 8 seconds to display a pop-up for the Filter key and click no. If your keyboard is still not responding, then it might be an issue with the driver. Try to restart the computer and reinstall the current driver for the keyboard.
Losing Charge Quickly

Faulty Battery
On average, a fully charged battery should produce about six hours of power. If it barely makes it past a couple of hours/minutes, then you should purchase a new battery.
Touch Screen Is Unresponsive

Defective Motherboard
If you know that your computer is on and the laptop screen is blank with nothing displayed, this might be caused by a faulty motherboard. You should transfer all of your data to another driver to make sure that it's safe. Before going ahead to replace or repair your motherboard, you could try performing a hard reset. To perform a hard reset, you will have to press and hold the power button for ten seconds; you also have to disconnect any external power supply going into your computer. If your computer has a removable battery, you can remove it and reconnect it after the hard reset process. After this process, you can reestablish your laptop's connections. When booting the laptop again, the Windows warning screen may appear stating that the "Windows was not shut down normally." Select the "Start Windows Normally" dialog and Windows should start again. If it doesn't work then you might need to get your motherboard replaced.
Faulty Driver
If your touchscreen is not working, it could be that your touchscreen's driver needs to be reinstalled and it can be done in your device manager. To do this, you will press the Windows key + the X button simultaneously and pop-up window will appear; you should see the device manager on the top left side of the pop-up window. Search for your touch screen device on the list and right-click on it, then select uninstall and follow the prompted indications. You will have to restart your device and go back to the device manager. On the top of the screen next to the file option, there is an option that says "Action" and you will click it and scan for hardware changes. Install the detected Touch screen after the scan and restart your device, it should work after that.
