My laptop turns off without any reason

After I turn on my laptop it works fine for 25-30 minutes and after that just turns itself off without any warning. When I turn it on again, it works for some time and then shuts down again. What is going on? How can I fix it?

Most likely you experience a laptop overheating problem and it would be fixed by cleaning the cooling module – the heat sink and the fan. The notebook processor produces a lot of heat when the notebook is turned on. The cooling module helps to keep the CPU cool when the laptop is working. The cooling module includes two parts: the heat sink and the cooling fan. The heat sink is attached to the CPU and helps to conduct the heat from the processor to the radiator. The cooling fan blows on the radiator and helps to disperse the heat produced by the CPU. The laptop will overheat if the heat sink radiator is clogged with lint and dust or if the cooling fan stopped spinning.
If your laptop shuts down after some time without any reason and warning, check if the cooling fan spins. Usually it makes some noise and you can hear it. If the fan works fine, then check if the heatsink is clogged. In some cases you can clean the heat sink with compressed air, just blow inside the fan openings on the laptop bottom. If the heatsink is completely clogged, then it is necessary to remove the heatsink for cleaning.

    I was having this problem out of no where as well when the screen would not turn on but i would hear the fan and the computer seemed to boot up. This started to happen right after i was trying to use my recovery cd’s to recover windows. Half way the computer would turn off and when booted would say ntldr is missing, or “Inf file txtsetup.sif is corrupt or missing, status 14. Setup cannot continue. Press any key to exit.”
    I thought the discs were dirty so i went on a journey to fix the discs and even tried using brasso metal polish “thanks to searching google on how to cheaply repair cd’s” the cd’s came out better and so i tried it again and again the same result. I tried clearing the cmos by supposedly holding down the power button for 30 sec with no power source attached and … It didnt work. I scratched my head and dived into google for hours, searching desperately for a solution that wouldnt mean sending my laptop in for repairs and thus throwing away my lunch money for a year! It turned out to be that the fan was dirty and was causing the computer to shut down halfway thru installation and not letting the screen come back on. Make sure your fans are clean. A computer can get very!!! Hot! And the only thing keeping it cool is a small fan. Hope this helps

    Hello. I’ve got an N1 Smartbook laptop and the same with you, I’ve got the same problems. Only, there’s something worse that I can’t fix alone. My laptop computer turns down by itself and then reopens by itself. Or when you’re using it, if you shut it down it restarts alone and then keeps working for some time. It will eventually shut down again and then later, open again. It only cools off when its battery loses charge. I just manage to use it this time. Can you help me.

    Hi.
    I have a dell I’ve had for about 2 years now. For the last 5 or 6 months, when the laptop gets a little warm, it’ll shut down on me.
    I did some research and found out about a thermal failsafe with my battery. I don’t know if that’s it, but if it is, is there a way to turn the failsafe off? It gets annoying when I’m in the middle of a game and my laptop suddenly shuts down.
    Any help would be greatly appreciated.

    and now to the reason i was hunting info this morning i have a hp dv 1000 series that has the typical power issue ive tracked it to a bad diode which i tried to replae to a similar one but without knowing what its value actually was the original was in two pieces and fried the upper half had no markings it is small rectangular it is maybe an 8th of an inch long its black soldered to the board on both ends it is located under the plastic isolator between the mainboard and heatsink assembly i am guessing it is labeled as component pl75 but could be mistaken thanks for any help i recieve and to those who read this posting

    while surfing around i came across this forum i have a little bit of advise for the guy with the gateway 7330gz as ive personally owned one and its older sister m520 both suffer from the heatsink getting clogged with dust/dirt ive found ive had to dismantle them and clean the fans and the heatsink assembly as often as once every 3-6 monthsits actually fairly simple to do after you remove the keyboard and then the plate under it as well it takes paitence and a bit of time but after doing it once i learned a few shortcuts to make it a faster process and always remeber to clean the old thermal grease and apply new for best results another thing is the cloth filters on the side pannel and the buttom board can also become clogged i removed mine possibly why ive had to clean mine so frequently lol

    Dear Laptop Freak:

    I have an Averatec 3700 and I been getting the message “New Hardware found” then my wireless will only work for like 20 minutes and the laptop restarts automatically. I Can’t update Bios because I don’t know my Supervisor password. I also think it may be a heating problem but i’m not sure what is going on with my Laptop.

    Cordially,

    Hey, thanks for your advice to others, my HP laptop dv6000 Special Edition was shutting down on its own. I never turn off the laptop, so its been on for a good 4 months.. I just tried blowing into the fan and getting all the dust, and my laptop went from uber hot to chilled nice room temperature within a matter of seconds, and, it doesn’t shutdown anymore at random. :)

    Kay,

    The reason I haven’t done that is because I’m clueless when it comes to taking apart and putting together computer parts and I’m scared of doing the wrong thing so I was hoping to get a definate reason for whats going on before I do anything.

    I wouldn’t take it apart unless you know exactly what you are doing. You can damage the laptop.

    Try cleaning the laptop with compressed air without taking the whole thing apart. Buy a can of compressed air in a local home improvement store and spray the air inside the heat sink grill on the back. After that spray it inside the air intake on the bottom.

    Jonas, thanks for responding. The reason I haven’t done that is because I’m clueless when it comes to taking apart and putting together computer parts and I’m scared of doing the wrong thing so I was hoping to get a definate reason for whats going on before I do anything.

    Would I just screw out the tiny screws on the bottom and remove the whole thing? Or is it a section of it?

    Thank you!!!

    Kay, try reading the article. If you try to remove the laptop’s case lid where the CPU is and check how much dust is there, it should give you a clue as to whether or not this article is your answer.

    Hi,
    I have a Dell Inspiron 1501 and for awhile it has been shutting off completely all of a sudden. I thought it was because my charger was torn up and my battery cells were nearly dead but I have replaced both and it still does the same thing so I don’t think its the charge. It does not happen often. It’ll range from 1 -2 times a day and then sometimes not happen for a week or 2 and happen again. I have heard maybe the motherboard is shutting down due to overheating, but sometimes it is not even hot. Please let me know what you think it might be. I have final exams in this next week and a half and my laptop is very important!!

    I just wanted to say thanks. My computer had this problem, but after cleaning out the heat sink (which was completely covered in a heavy layer of dust), problem solved. No wonder it wouldn’t work. That stuff seemed like some pretty effective insulation.

    You’ll probably find that there are dry joints on the mainboard that are causing it to restart irratically, or potentially a crack in the mainboard… Make sure to totally illiminate overheating problems first, try replacing hardware with spares (if possible, dont go spend money on this as yet), if you’re uncomfortable doing this yourself, take it to a Computer shop and get them to do it fo you.
