Charging ideapad 100s

Can I leave my ideapad 100s plugged in over night? Longer? Or do I need to stay with it and unplug it the moment it is at 100% to prevent damage to the battery?

Re: Charging ideapad 100s

Hi Zappp,




Nowadays, laptop batteries have a special chip on itself that prevents overcharging aside from the power management settings (power save mode as an example). While charging, battery charge consumption is turned over to DC and as it reaches set max charging, dc power is the ones that maintain needed power to the system.  It is ok to have the machine plugged in longer.


From the hardware manual on page 22:

"Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or
from having a shortened life." 


It has been a practice before to unplug any electronic device as it reaches 100 %. With the newer technologies we now have, we can have a peaceful mind having it stayed plugged in.


Just on a side note with any electrical machines, there are power surges and events that we do not expect so personally I would rather have it unplugged and fully turned off if not needed. Proper safety alternatives like surge protectors and having the machine safe from external risk (like pets/ kids/heat/wind/ non-heat resisting surfaces ) are things that can be considered.


An additional reference here .


Hope this help answer your query.
