Ok thanks, I'll try it too

I'll try also Memtest, thanks!

It turns off suddenly. I'll check these tests with Lenovo, thanks

Thank you very much for your help!

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

By safe I mean about privacy, if there's possibility that someone can "intercept" the photos of the child. Sorry if I didn't explain it well

Thanks for tour answer :)

Wow! I'll try everything you've said! Thanks you very much!

Thanks!

Thanks, I'll check that.

Thank you very much!

I've checked Emma Congdon's books and they're perfect. Thank you so much!
