The appeal of a laptop is its portability and convenience, which makes it ideal for working on the go and business trips. Laptops are only as good as their batteries, however, and proper care of your battery is essential to making sure it retains a long life and charge. Leaving your laptop plugged in constantly is not bad for your battery, but you will need to be careful of other factors, such as heat, to prevent your battery from damage. Show Laptop Batteries

So, i have this lenovo ideapad z400 laptop that have energy management software that allow me to make the laptop charge only to 60% and then not charging, i find it was good but after using a while (in windows 8.1), it just like my laptop can't recognized very well the battery capacity. 100%-30% is decreasing normally but after it reach less then 30% it suddenly jump to 7% and
warn me to do charge or sometimes sleep/shutdown my laptop. Luckily there is also calibrating option in that software that can calibrate the battery and make it right... but it is tiring task since it need to charge and discharge completely and i ever using other laptop before but never experience all this problem, i have conclusion maybe because of option to only charge to 60% and then i get another new question now, if i'm not using that software to limit only charge 60%, is it
safe for me to charge to 100% and leave it plugged in? (since i use my laptop all day and this laptop battery life only around 2-3 hours)

it safe for me to charge to 100% and leave it plugged in? (since i use my laptop all day and this laptop battery life only around 2-3 hours) It sounds like you simply use the laptop at home keeping plugged into the AC outlet all the time. Since you cannot remove the battery from the Z400 laptop, it is best to only allow it to charge up to 60% and leave it alone. The energy management software is purposely only allowing the battery to charge to 60% to help prolong the life of the
battery. The reason is because as the battery is charged near it's maximum capacity a chemical reaction start to occur. The high charge causes something referred to a lithium ion plating. Lithium ions is allows the battery to hold a charge however, when the charge is too high the lithium ions starts to clump together to form lithium ion plates. When this happens the battery capacity begins to drop because the lithium ions that have started to clump together will no longer hold a charge. The result is that the battery life will begin to drop and the more the battery is kept near a full charge, the faster the battery life will decrease. When you know you are going to be using the laptop away from the AC outlet, then at that point you manually override the energy management software to allow the battery to be charged to 100%. That way you can use the laptop for as long as possible. When you return home and plug the laptop to the AC outlet again for a long time, then allow the laptop to charge to only 60%. The "calibration issue" you are having seems to only be a side affect of the energy management itself. Yes, it sounds like it is annoying, but the flip side is that it prolongs the useful life of the battery so just allow the battery to charge to 60%. Simply consider it as a maintenance you must do one every couple of months. The IdeaPad Z400 is known to have poor battery life even when new so 2 - 3 hours of battery life on a full charge sounds about right; depending on what you are doing. Oct 31, 2003 708 0 20,410 241
It is not good for the battery to be at 100% charge all the time, as this can limit the long term life of the battery. http Jul 3, 2012 149 0 10,910 57

Is it OK to leave your laptop on and plugged in all the time?Leaving your laptop plugged in will not cause short-term damage, but if you only ever use it on AC power, you'll almost certainly find that after a year, the battery's capacity has been significantly reduced. Similarly, if you only ever use it on battery power, you'll get through the battery's discharge cycles quicker.
How can I make my Lenovo laptop battery last longer?Save big on battery life by turning the brightness level down to the lowest comfortable level. 2. Unplug unneeded devices. To save battery life, remove other devices like phones or headphones that are charging.
