can be a good first step in the right direction. Overheating is definitely one thing that is going to indicate that your laptop needs to be repaired as much as possible. For the most part when you look into using your laptop it will need to maintain a consistent temperature, and if you touch the underside of your machine and find it to be unreasonably hot then this might indicate that your laptop is heating up far too much and you would need to make sure that this never happens again.
If you feel like your laptop is getting too hot then you should definitely look into making sure that this overheating issue is dealt with. More often than not this would mean that you would have to clean the fan out as well as the heatsink as when these two elements are compromised this leads to your laptop being unable to maintain a temperature that would enable it to continue working at maximum capacity at the end of the day.
