Hello everybody,

I have a Lenovo B50 Laptop but I can’t use it because when I’m using it, it shuts down randomly. I thought it was a battery problem and I’ve changed it but it didn’t work.

I’ve tried to install Lubuntu on it thinking that it was a Windows problem, but nothing. While I’m using it (Internet, Libreoffice, etc.) it shuts down randomly.

What else can I do? There is any tool that I can use to search the problem?

Thanks in advance

    Randomly or after a set time of use or intense use? Could be processor is overheating past safety thresholds (new thermal paste could fix this IF that’s the issue).

    I’d try cleaning vents and fans before changing thermal paste though. Could be they’re clogged and not working right.

    Failing that it could be multiple things. But I’d try to address cooling being adequate first. Make sure vents are unobstructed during use. Use it on a flat hard surface, clean the vents with a vacuum and/or canned air duster.

      Thanks for your answer. It happens randomly: I use this laptop only for searching on Internet and write docs in LibreOffice. I’ll try to clean vents and fans and if that doesn’t work I’ll try with the thermal paste

        Well re-applying thermal paste is a big matter. I’d try stressing it and seeing if you can force it after cleaning the vents.

        So do things to stress the processor and see if you can force it to happen repeatedly. If it is a thermal issue you should be able to cause it by inducing high load. If you can’t it points more towards other issues. A fault in RAM or the motherboard for example, a loose module or connection, etc.

        And just FYI if you need more help in future this community isn’t intended for it. Try posting in a tech or computer help community for a better chance more people engage.

            Other than cleaning the vents, I would also see if any problem come up with a few passes of Memtest, and with a linux live system (I suggest Ventoy if you don’t have one ready, you install it once on a usb pen drive and from there on you only drag and drop the .iso files)

    Try running it with the battery removed to eliminate that as a potential issue. Running memtests, HDD tests etc will further help eliminate potential issues . This could be anything from somehow the system is grounding out, bad battery, bad ram, bad motherboard, blown capacitors etc

    Doesn’t shutdown or simply turn off? If it’s shutting down then look at the event logs to see what’s issuing the shutdown command.

    Lenovo has a bootable usb or a windows application that performs a number of hardware tests. Run it and see if any issues are uncovered.
