Problem with Lenovo B50 (lemmy.ml)

submitted 9 months ago by [email protected] to c/[email protected]

10 comments fedilink hide all child comments

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

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)

I'll try also Memtest, thanks!
