Solved!

Is it bad for battery to leave it plugged in all the time?

I know this question has been around a long time, and I know there are plenty of answers out there, but I am finding a lot of different opinions out there, and many of them are old and perhaps not relevant to today's smart batteries, so I'm starting a new thread for this question:

 

Is it bad to leave the laptop plugged in all the time? I don't mean like weeks or even days, I usually unplug at night or when not using. What I mean is during my 8-hour work days, is it OK to just leave it plugged in the whole time? Or, should I let it discharge and then recharge, either a lot or occasionally? I'm most concerned with the long-term battery life here...thanks for your thoughts!

The "usual" advice still stands.

 

A battery that becomes "lazy" -- never fully discharges (and is fully recharged) -- loses its ability to deliver "full-cycle" service.

 

Computers are getting smarter -- slowing-down the CPU, and dimming the display -- when running on battery power, in order to extend the usage of the current charge.

 

The power-management software in some Lenovo computers even _refuses_ to fully-charge the battery, if the software detects that you typically run the laptop on AC power most of the time.  This extends the life of the battery.

Hi:

 

HP has a link for how to get the most life out of your notebook's battery.

 

http://support.hp.com/us-en/document/c00596784

 

And yes it is fine to leave it plugged in for not more than two weeks, according to the above link.

I already looked at that document but I do not see where this Q is answered.  It does not discuss if it is bad for battery to leave it plugged in all the time.

The document posted above clearly states>>

"If the computer is run primarily on AC power, allow the battery to discharge completely and recharge once per month."

Although I interpret discharge to 15-17% as optimal-not dead flat.

The last document posted above by @EddyK I couldn't get the document to open that you mentioned was invalid and then marked as Solution so don't know if it is same.

I did not see that in the document, do you know the "topic" it was listed under?
