My laptop is dying out
When I tried to turn it on last week it gave me a memory error (beep -- beep³ -- beep³ -- beep) and then powered off.
After several painful attempts at executing memtest, which all resulted in a power off, I quickly selected the option to memtest in safe mode (whatever that would mean). After 1.5h, the test was completed on the first core. I then pressed ESC and tried to log again.
...And this time, I could proceed and log in! But I'm scared now.
Time to buy a new (second-hand) one, unfortunately :(
