It is the most dangerous problem as it can cause severe problems to your laptop like your laptop can go dead due to the faulty power supply. Because the value of current decrease and also increases, so it greatly damages the battery and laptop itself.

  1. None of these are my problem. My laptop turns itself off and doesn’t restart, every two weeks on a Tuesday, anytime between midday and midnight or so. I have looked for the programme that is doing this, but cannot find it anywhere. It started after I did a back up to a portable hard drive about six months ago. At first it was every Tuesday, now it is every fortnight. I used a My Passport hard drive to back up to. I think I must have accidentally told the laptop to back up or something, even though I don’t have the device plugged in and haven’t since that back up. This is driving me mad now, please help.

    1. You might want to delete any backup software of My Passport. If it doesn’t work, least you can do is try to reinstall windows completely. I hope it will fix your problem.

      1. my laptop shuts off randomly .After i can not start it even if i click the power button. But i can start the laptop by clicking power button only when it is charged .How do i fix this?

  2. Help, My laptop was on charge and switched on. Suddenly it shuts itself down and the light that shows it is charging turned of. I tried to switch it on but it can’t.

  3. does it once a day whether on battery or plugged in-usually a morning thing but not always–it NOT over heated -has always (so far) rebooted on it’s own –and O know many friends with Lenovo and they ALL say theirs does the same thnig–come Lenovo step up on this subject

  4. My laptop often shut down randomly when I play tf2 but I assume it is because my laptop
    is not suitable for gaming and might caused by hardware failure as listed above.
    I feel very disappointed and I will a purchase a suitable laptop for gaming in the future.

  5. My laptop keeps shutting down and restarting after about 5 minutes or so. When it starts it says that is there is an application error.

    1. Check your RAM and your battery. I’m not an expert but it seems like your RAM is failing, or your laptop doesn’t have enough power for it. It could be also a CPU problem…

    1. I start Micro Soft Edge and it works fine for a while then it shuts down. I start it back up and same thing happens.

  6. my laptop shuts down by its self and will not switch on again after using it every 20 minutes unless i connect my charger to it.
    NB: there is still power in the laptop before it shutsdown

  7. My laptop suddenly shuts down and the power supply to the laptop is steady.(even when its cold, no excessive heat. )and the shutdown pace continues to increase. what could be the problem.

    1. u need a new hard drive that it takes a lot longer to boot the older it is because the mechanical arm is wearing out and is taking longer to find the necessary info to boot I suggest a SSD it is much faster but the down side it cost more to get more space like a 1 tb hard drive might cost $100 but a 1 tb SSD might cost around $245 just because a SSD is stored on a chip rather than a set of disks

  8. my laptop just start for a few seconds with an unusual sound of fun then turns off again…. what can be the problem?

    Help, My laptop was on charge and switched on. Suddenly it shuts itself down and the light that shows it is charging turned of. I tried to switch it on but it can’t.

    1. Try taking out the batt and memory stick, then hold down the power button to about 1 min . Then replace items then power the device back up and see what happens

  12. josophina emvula

    I can’t put on my password on my laptop, when trying to do this, sometime the keys are pressing themselves . when I choose to use the onscreen keyboard it goes on .

  13. My Lenovo keeps turning on and off without touch it or soon I open screen automatic turn on and off. What to do !

  14. My toshiba notebook laptop for sometime now has been acting funny. when i switch it on it boots and display and ones i press enter it responds and after some few secounds it goes off by itself

  15. My laptop (Toshiba dynabook), each time i put it on i observed that it display on on the screen and when i press enter it on for sometime and goes off by itself. What could be the reason

  16. My laptop goes off suddenly.
    When there is still enough battery of about 50% .

    When it goes off, I have to charge it for about an hour before I will be able to turn it on.

    1. Replace your battery. I feel like the system thinks that there is more battery capacity than there actually is, making your computer shut down randomly when the battery is actually 0%.

      Also, if you didn’t know, the capacity of batteries become smaller over time. For example, a 4,000mAh battery could really be a 2,000mAh one after using it for a long time.

  17. Biswanath Debnath

    My laptop turns off exactly 2 hours after I turn it on, every time, everyday for the past two months. I suspect this is a processor issue but am not sure. I do not understand why the exact 2 hours gap for self-turn off. If anybody is knowledgeable about the issue, please educate me. I will address the problem accordingly. Thanks in anticipation.

  21. Miriama Tamaivena

    My laptop usually just turns off but then in order to turn it back on, I have to connect my charger. Why does this happen? What should I do to fix the problem?

  22. Most commonly an overheating problem due to dust build up. Hence after a period of time the circuitry switches off to prevent damage. Get someone who knows what they are doing to clean out the dust carefully.

  23. Yesterday night I was working on my laptop for 4 hrs. And randomly it got shutdown, but it din’t get fully tuned off, there was a blue page in my lap, (there showed a notification as OVER HEATING AFTER THE DISPLAY OF BLUE PAGE) then I turned off my lap using power button, then again I restarted it, it happens to be the same thing, So again morning I did the same thing as restarting but it became well. I consulted about this with some one they said it is due to battery problem,but I changed my battery recently only. What may be the cause for this problem MAY BE BATTERY PROBLEM or OVER HEATING.
    Two days before I charged the laptop for more than usual hours.
    kindly notify the reason.

  24. Help! My laptop suddenly turns off after i updated the drivers using or when a device (mouse, keyboard,etc) was put or removed.

  25. Twilight Sparkle

    So if my laptop says “Locking” right before it shuts down, what is my problem? I don’t know, maybe it’s just because this laptop is old, but if anybody can help with my problem, please say something. Thank you.

  26. None of these problems are for my ACER Aspire E15, it just shutdown while I was watching a movie this morning and won’t boot again.
    Help!! I am so worried.

  27. my laptop shuts off randomly .After i can not start it even if i click the power button. But i can start the laptop by clicking power button only when it is charged .How do i fix this?

  28. My HP laptop turns off when I pick it up. I have never dropped it. It is under a yr old. Has plenty of battery.

  29. I have 2 older HP laptops that both started shutting down without warning within days of each other. Could a Windows update have caused this? Or, why would 2 laptops start doing this at the same time? Both ran great before this, both have been on cooling pads for a long time. Just seems odd to me that it would be a problem with the computers themselves when it is 2 computers at the same time, right?

  30. MY laptop (Dell Latitude e5420, 16 GB RAM, i7 2760qm) shuts down intermittently (not very often, but quite often) when on battery power. The battery indicator turns red and starts blinking, then it just switches off. The battery, charger and RAM are absolutely fine and the system does not overheat anytime. What could be the cause of the problem and the solution to it?

  31. I had my computer on the charger as I was trying to finish up an assignment. I walked away from the computer for approx 20 minutes and when I come back, it was off and I couldn’t get it to come back on I removed the charging cord and my computer is very hot to the touch. I’m trying to cool it down right now?
    What is happening?
