Question: what is the battery life without the adapter
Document: I love the long life battery. I forgot to take my cord on a trip and was amazed at how long my  charged battery lasted.
Long battery life. Easy to pack and go. Fast. Norton already installed. Can't go wrong with Lenovo products. Love it!
We bought two of these. It's a great laptop and we could get it in Windows 7 Pro instead of Windows 8 Pro. It is light, has a long battery life, great keyboard, quick and really easy to use. It's a very smooth performer and feels very solid. The bigger screen is well worth it as well.
Slightly on the higher end of my budget, but overall great computer. It's plenty fast and functional. Would recommend it for just about anything the everyday user would need. Graphics could be a little better, but plenty of processing speed, power and multitasking ability. Battery life is great, too. Very happy with the purchase.
I highly recommend Lenovo Thinkpads for any business student! The only thing I wish it had was a longer battery life. It only lasts about 5 hours for me after being fully charged, but other than that I think it's a great device for a great price.Honestly, you don't need to spend over $1,000 to find a great laptop.
1) SSD is super fast and they can last up to 25-30**(further research needs to be done but after 4-5 years i'm in the market for a new computer) years (of course the newer SSDs) 2) my god the battery life has drastically improved from 3.25 hours with the old HDD to a whopping 4.15hrs (and thats the battey that comes with not the 75+).Conclusion:Two thumbs up.
Comfortable keyboard, but did take me a while to figure out how to right-click for copy and paste, as there is no right-click button - you click on the lower right section of the touch pad. I usually use it with a mouse because I'm old school; just like the control of a mouse. The battery life when fully charged is not quite what it claimed. Usually 4 hours, not 5. But I didn't buy this to take everywhere, its just replacing an antique desktop.
I love the fact it came with Windows 7 Pro.......just what I needed to replace XP without much training for the new system. Good job Lenovo!!!!! !
Again, something annoying when I'm so used to tapping this button without having to look down. More times than not I'm closing this file pop-up window rather than being able to delete something I'm writing (even as I write this)- The location of the USB ports are on the side. Two on the left side and one on the right.
It appears to stop the charging at ~92% a majority of the time with this setting. I'm not sure why but the engineers who designed it know a lot better than I.For those who are interested in Linux compatibility. I installed Ubuntu 13.10 64-bit without a hitch all hardware except the fingerprint reader is properly detected and just works. I haven't fiddled getting the fingerprint reader to work yet. This is my first fully EFI enabled system.
Answer: HI Carol,You can adjust the performance of your battery.  High performance gives around 3:15 hours and low performance gives 4:40 hours on my computer.  I like this computer in general.  Hope that help!
