This is happening because your laptop is under a big load or it can’t breathe. Make sure nothing is blocking the fan vents and check for viruses/malware. If nothing above worked then the vent inside the laptop is probably dirty not allowing proper airflow. You can find guides on iFixit and YouTube on how to open up the laptop. If not comfortable on opening up the laptop to clean it, you can take it to a local repair shop. Hope this helps.

Try pulling the battery for the camera and let it sit for 5-10 minutes. Put the battery back in the camera and see if that resolves your issue. If not, most likely the lens is slightly out of position.

This is a harder issue to solve. Try a different power supply for the laptop. If that didnt work, unplug the battery. A battery can short circut and cause the laptop to not do anything. You should be able to find a guide that shows you how to open up the laptop.

Take out one stick of ram and see if that works. Since your charging port has a spark, its probably not a ram issue, but try. The way that you were describing the laptop behavior sounds like a ram issue to me. Hope this helps.

Hello, did you make sure that the battery is plugged in fully? Maybe try to unplug it and plug it back in. Was your old battery keeping a charge? If not, try to use a different power supply for your laptop. If that doesnt work, check to see if the charging port is dirty.

An outdated device can have performance issues. This drop of performance could be making your microphone not work correctly.
