ideapad Y460 battery issue

I have been noticing that my Y460 battery loses battery charge rather quickly even when turned off. I was gone travelling for 2 weeks and returned home with the laptop battery completely drained (it was charged to 100% before I left). I left it unplugged from the wall power outlet, and removed any plugged USB devices from its USB port. When I came home, the laptop coudn't even power on.

I also notice that even when I fully charge it to 100% capacity, and leave it just for 1 or 2 days, the battery capacity would be somewhere around 90% when I turn it back on.

My other computers including Sony TZ and a small sony netbook could hold most of its charge for a week.

Could some confirm this to their Lenovo Y460.

 

2 weeks is a bit of time, but it should have a well enough battery life to start it. As far as day today, yes that does seem a bit extreme. Where are you keeping the battery when it is out of the computer? Also, how is your battery life when doing normal tasks at 100%? You should be getting almost 5 hours out of it.


Bottom line, you should get a replacement if you can. The problem doesn't seem normal and it could cause more problems down the road, and a harder time getting a replacement battery.

 

I am interested to know as well, what your regular battery life is unplugged and on the power saving gpu. From what it sounds like, I agree with Threefifty that this does not seem normal.

 

I will be posting my test results tomorrow and see what I get. I'm charging the lenovo right now.

 

Battery Test #1

Scenario 1: WIFI ENABLED for 2h:42m (web browsing, youtube-320p & 480p videos, speakers enabled to 50%,) ; Windows Media Center (mp3 playback, photo playback, speakers enabled to 50%) for 15 mins, Microsoft Games (solitaire, Mahjjong) for 10 mins, Cyberlink Youcam Software for 10 mins, Lenovo Media Show for 10 mins, ATI Graphics DISABLED, Screen Brightness set to 1 Bar level.

Battery Life: 3h:40m

Note: The computer was NOT ON continously for 3h:40m. I had to do 3 shutdowns and 3 power-ons to reflect a normal usage of an average person that will use the computer on and off throughout the day. With that, I suggest subtracting -/+ 1% to 2% of battery power everytime the laptop had to power on (hardware and software load power consumption on startups).

 

Hmm. While on battery, the results seem descent. I was expecting poor times considering how much juice it looses when it's not on. I have no idea what to tell you. Where do you store your battery when it's not in the laptop? From what I've heard from just about every person on here is that a cooler place is the best place to store a battery when not in use over a long period of time. Some people ever pop it in the refrigerator. I would say it's up to. It seems to perform just fine when you're using it, but a lot of drain when you're not.

 

----
My next battery test is to wait for 24 hours and see how much juice is being drained from the battery when it is powered off. So far, the first battery test shows that I'm losing about 4-5% of battery power which is a lot. I'm not sure if the battery is defective or if the laptop is consuming battery power even when it is turned off. Something is not right.
To answer your question, I have not removed the battery ever since, esp. when I don't use it for a period of time (2 weeks or so). I live in SF bay area and humidity and weather is comfortable. Inside the house, it is around 68% and normal humidity.

 

Battery Test #2

Scenario 2: Charge the Lenovo Y460 battery to 100%, turn it OFF, leave it for 24 hours, and then turn it back ON. Temperature of room: 70 degrees Fahrenheit; Normal Humidity

Battery Life: 94%

Note: When powered ON after 24 hours, the computer started with screen brightness set to 1 Level, WIFI ENABLED, ATI Graphics DISABLED, and Super Energy Saver Mode . It gave a reading of 94% battery level.

I will buy a secondary battery ($79) from Lenovo to see if i get the same results. If the original battery is proven defective, then I will initiate a battery replacement from Lenovo.

 

That sounds like a good plan Felix. It should help nail down whether you truly have a defective unit or not.
