During GUADEC I decided that I need to buy new battery for my Dell D400 laptop. Current one is giving me 40-50 minutes of working only. According to ACPI informations it is really low charged:
11:44 hrw@maluch:BAT0$ cat info present: yes design capacity: 42000 mWh last full capacity: 11530 mWh battery technology: rechargeable
So it does not get even half of nominal charge. I wonder how much time I will be able to get from 4400mAh battery (current one is 3800mAh when most of available ones are 3600mAh).
And this time I really need to buy one.
UPDATE: bought one — will get it in few days.
