We replaced a laptop battery this week after it had become worn out to the point where it lasted only about 15 minutes. I was slightly distressed to receive a ticket about it this afternoon:
“The new battery went flat after 3 hours use this morning… It has now been on charge for 2 hours and is reading fully charged as the charging light has just gone out. Not sure if it’s a faulty battery or something wrong with the laptop.”
This was from someone who has been looking after a classroom set of laptops for over a year, and had the performance of the entire rest of the set to compare it to.
This person is nuts.
