Resolved Leaving Laptop adapter ON and connected even after shutdown.

Hi;

I want to be confirmed that some people say that if you have shutdown the Laptop, you must unplug the AC Adapter otherwise battery can be damaged. I am not certain as system by-self control the charging. So if system has been slept, there would be no charging and so if adapter is still powered on, for me there is no problem. Am i correct?

 

Hi, I've left my Laptop connected to the charger when the laptop is shut down and had no adverse problems, even for several days before I noticed it.
Compaq Presario shuts down the charger when the battery level of charge is up.

Check with your manufacturer and follow their advice. Neil.

ps. I think if the battery is L-ion (lithium) there is no problem at all.

 

Battery "damage "? The typical controversy is over battery life and that is one of those things armies of experts takes different sides on.

I leave the charger in my 3 1/2 old Toshiba plugged in all the time. Some say that will shorten the battery life. I don't see it with today's Li-Ion batteries - or my Toshiba.

My advice is to read the manual that came with your specific notebook, and follow the advice provided there.
