How long should you wait to turn on laptop after it overheats?

    first question that I got, is why did you laptop overheat. the best possibility is that the internal fan has failed it self. try to find out that it works and then after 10-15 mins, turn on your laptop. if the overheating continues, the best option is to take it to an authorized service station.

    Hello Fred,

    Because computers are not designed to overheat on a regular basis, you may wish to consider a vigorous cleaning of its fan and other components, as others have suggested. This is because repeat overheats wear down your fans and CPU - in the long run, the heat buildup will only get worse.

    Some of the better articles I've read on the subject can be found here, regarding laptops.

    Another possibility causing the heating issue could be an overworked CPU due to too many startup programs and/or malware running in the background. Tina Sieber discusses some of the key causes of restarts/crashes in this article. A common trouble-shooting methodology is to isolate the cause of the problem and in computers that's either hardware or software (or both). It's a highly useful read.

    Frequently, however, heat problems are either a design defect and/or dust combined with an overworked CPU. In such a case, you may need to implement a variety of solutions, such as cleaning your computer + removing startup entries/virus sweep + getting a cooling pad. The important part, through this frustrating process, is that you stay calm and keep cool. ;-) Good luck!

    You can use the laptop as soon as it has cooled down, but, and it is a big but, it will just overheat again and may turn your laptop off or even do some serious damage, you need to get to the root of the problem as to why it is overheating and fix it.

    First of all check whether the fan is overloaded.If it remains overloaded all the time then you need to clean out your laptop.This means the fan is not able to direct the cool air towards the processor and other components(due to build of dust or pet hair).Second, do you use your laptop on places like your bed?If so I would advice against it.The fans suck up the cloth fibers and dust thus the build up of dust.Third, always use your laptop on a flat hard surface.If there is no proper airflow under your laptop then use something to raise your laptop so that there is proper airflow.

    What until its cool. Also, see what caused it to overheat, clean the fan grill(s), blow out dust with compressed air, or even get a cooling pad. Get one with a large fan rather than lots of little ones as it results in the same cooling but significantly less noise.

    The time is when it's comfortable to hold your laptop from the base.It usually takes 30 mins to cool down.

    Well, try to take away dirt from your fan and then try to start it again. If you have a hairy pet, hair might get stuck in the fan.

    1. clean your laptop of dust, hair etc.
    2. turn it on, listen if fans are running see if it still overheats
    3. if fans not running you have a situation
    4. if fans running but it still overheats, you might wanna buy a laptop stand with cooling in it, or move into colder places :)

    but to answer your original question, only turn it back on when it cools to the room temperature on the entire surface.

    restart system after it cools to room temperature

    the best time is when it cools down. To get more efficiency and don't want that your laptop is being heated it is better to use cooling pads and do not run programs which require high CPU usage when you do not require software.

    if it overheated this mean it has problem to solve first

    first of all use the cooling pad for your lappy

    Why did it overheat in the first place? Were the cooling vents blocked? Is the cooling system full of dust, pet hair etc.? Eliminate the cooling problem and restart your computer.
