So, why don't laptops completely bypass the battery when the battery is charged and the power is plugged in? If the laptop can work when the batteries are removed, it should be able to cut-off power to/from the battery when fully charged as well.
- rdtsc 17y agoWhen the laptop is at home, just charge the battery to 50% then remove it so it works only from the plug. I don't move my laptop as much as I did before and I noticed that I get much better battery lives than my friends who continuously keep their laptop plugged in and with the battery attached.
- mustpax 17y agoObviously this is the current solution. I was pointing out that laptop manufacturers could remove the need for fiddling with your power connection by automatically disconnecting the computer from the battery when it is not needed.
- eru 17y agoYes, but you need a way to tell it whether you don't want to use the battery in a long time (so 50% charge is good), or whether you want to get up and go on the road soon --- where 100% charging is nice.
- rdtsc 17y agoAllegedly Thinkpads have that. But I run Ubuntu on mine so I don't have access to the fancy bios setting utilities from Lenovo. I just snap the battery out. That seems to work for me.
