    Leaving a notebook while it is charging for a long time


    Hello everyone!
    I got a question about leaving a notebook while it is charging.
    I have a software on my notebook called Lenovo Energy Management, and there's 2 battery mode available, the one is "Maximum Battery Life" and the other is "Optimized Battery Health" so I choose "Optimized Battery Health" mode, and leaving my notebook while it is charging for about 5 hours. When I am go back home, I saw that my battery is stay on 60% and it say "Plugged in, not charging". It won't charge the battery higher than 60%, so I guess the battery is limited to 60% from it's full capacity. The question is, is it safe for the battery if I leave the notebook while it is charging for more than 5 hours even the battery capacity is limited?
    Thanks in advance.

    There's enough circuitry inside to protect from overcharging, just don't leave it on a soft (like a bed) and flammable surface (like paper) in case of something going wrong. If you are worried about battery "memory", that is all but eliminated with new batteries but was bad with old NiCads.

    So it is safe enough to leave a notebook keep charging without risking the battery life, I do it to complete my download by the way anyway I place my notebook above cooling pad. The hard drive mostly getting hot quicker than the orher peripheral, without the cooling pad I think it'll be bad.
    Anyway thanks for taking time to answer my question

    When you said "Safe", I thought you meant like about physical damage or fire etc.
    Check your manual for recommendation about battery life. Some manufacturers do recommend to charge battery to almost full state, remove it and store in dark cool place when using computer for prolonged periods where external power is always available, like at home and not carrying it a lot. Keep in mind that every battery has a finite number of recharges after which it starts to deteriorate. Newer ones are much better with that aspect but not perfect.

    looks similar to how my dell works with this setting

    its to save the battery by not keeping it at 100% charge (if plugged into the mains for long periods)

    every so often it will automatically switch over to using the battery, then when it gets below 50% charge it will charge itself up a bit (for me it charges anywhere from 50 to 90%), then repeat

    it simulates you using it on battery then plugging it in for a couple of hours to charge

    Thanks you CountMike I'll read the manual again tonight, I haven't found any information about keeping the battery while charging for long periods at the current manual or might be I skipped it hehe..


    paulsalter, my notebook will not do that as far I know, except I change the battery mode to Battery Health, if I charge it for long time without the Battery Health mode, it'll stay on 100% for a long time until I unplug the AC Adapter, unlike when Battery Health mode enabled, it stop charging at certain level.

    Depends how often you use it on the battery

    If you mainly have it connected via mains (long periods, ie weeks) have battery health mode enabled, it will occasionally use the battery and not charge it upto 100% (you might not notice too much, mine has gone from 58% to 57% in the last 3 days)

    if you use it a lot with the battery, have this disabled so you always have a full charge when you are without power

    from what I have seen, having it always on 100% when using the mains is bad for the battery as it is not getting any use

    Just one little advice, when updating windows, make sure you have battery in and it's plugged in the adapter too, in case of power failure you would have much less to go wrong with system.

    paulsalter, well sometimes (maybe everytime) when I play a game I always forgotten to unplug the charger and it always fully charge to 100%. I think that was really bad.

    Thanks for your advice CountMike, I always have battery and AC adapter connected when updating windows. But at this time, I don't know what is wrong but Windows Update isn't working, it's look like a network failure but don't know exactly why. Sometimes it will only updating when connected to VPN, but sometimes it updating directly with my network, maybe the provider block the Windows Update or my anti-virus block it.

    AV most likely. You can also download those windows updates from MS site and try installing them off line.
