That's done. My laptop is quite new (2 months old), Asus.

I used smartctl, short and long test. Both seems to be OK (the shell is at  
the end of this message), but one strange thing : both test are finished  
quite at the same I run them.

I will look for a driver that includes an administration GUI, I have no  
knowledge about.

Can this filesystem help me ?

Look this shell :

amel@laptopasus:~/fp/test.algoB$ perl -c algo-B1.pl
algo-B1.pl syntax OK
amel@laptopasus:~/fp/test.algoB$ ./algo-B1.pl
2020-01-01 - 2020-08-31
amel@laptopasus:~/fp/test.algoB$ ./algo-B1.pl
2020-01-01 - 2020-08-31
amel@laptopasus:~/fp/test.algoB$ ./algo-B1.pl
Undefined subroutine &main::lisblocage called at ./algo-B1.pl line 161.

I didn't change anything in algo-B1.pl between these shells. Some hours  
before that, I had the same problem : a function of algo-B1.pl vanished,  
I'm not sure, It is very possible it's the same.

This program access a postgresql database, impossible for me to say  
something, the main table has millions of records, the little tables are ok.

I will take a look of perl-testing.html ; bu there, I have only my laptop...
