This computer has a one year manufactures warranty. I would get in touch with them they should send a replacement part if needed.

I returned the Lenovo and went for an apple product. I m very satisfied about it and its super fast.

Must be defective in some way. I would send it back. I haven't had any problems charging mine. It charges fully and I am able to use it without it being plugged in for at least a few hours.

that's an issue with the battery. you are gonna have to contact customer service for warranty replacement.

Aren't *all chargers used in the US 110v? In other words, yes, I think it will. Particularly if it's a charger that *came with the Lenovo. If it isn't, even if the plug fits, you might have a problem not so much with voltage as with wattage. In my experience I've run into 90W and, I think, 70W chargers. If the BIOS expects 90, it won't work with some other number - or perhaps the charger (aka power supply) will *power, but not charge. I looked around quickly, and those Lenovo chargers can be bought for anywhere between $45 and $9. $45 is ridiculous when the whole laptop can be bought for $120 - in other words, don't buy from ridiculous people :).

I'd work to get my money back NOW! Don't make the mistake I did by working through the very long process of dealing with Anker's customer support (it took me 3 months until I demanded Amazon refund my money) as Amazon pushed me to do. Return the thing for a refund. I had the same problem with an Anker battery not charging in my Lenovo v570 laptop. Amazon told me that they did not work on customer support, so I went to Anker. They ran me through a bunch of things, with my making several contacts. Finally, they had me purchase a new adapter, the box in the electrical cord, and even after all of this time and expense, it still wouldn't charge. It took me 3 months to work through all of this til I finally sent it back. And the is what I suggest you do: don't work to repair the issue, ask Amazon to let you send it back and purchase a battery from the manufacturer of your machine. If it's a Lenovo, Amazon sells lenovo batteries. this is in no way a reflection on amazon and the great service they provide. It's just apparently that Anker sells a lot of batteries that don't work well in some computers.

After my first charge began to decrease to one or two bars and I had not used it for a couple of days, I turned it on to check the battery level and it went to a green screen and then to a blank screen. I put it on the charger and got no reaction. Left it on charger for a couple of hours, still just a bland screen. Unplugged it and pushed in the reset button under the battery. Did this a couple of times and finally got the regular power up screen. Have charged battery several times since and all has continued to work well. Hope this helps. Try the reset several times if it doesn't work the first time.

Hi, I am having the same problem with mine. I am sure these are defective items that are being resold. I have to shut it down, power cord in, turn it back on and then manipulate the cord just so. Sometimes it takes a few tries. When if starts to charge, I leave if alone, because it will stop even if lightly tapped. The charge doesn't last very long though. Very disappointed. I should have returned it when I got it.

Yes, I double checked and then triple checked.When I unplug the laptop and plug it back in. It will show it's charging then just stop. It just won't continue charging or stay fully charged. The other battery did the same thing then just stopped being useful.

The simple act of installing the battery in your laptop and plugging your laptop into your wall outlet should charge the battery. sounds like yours is defective.

Hello, I have a gamer type laptop, it requires high amperage. The charger gets very hot, and when my battery is low, during charging the screen flickers, not enough juice in the beginning. But it does work, hope this helps

I tried 3 larger batteries of different types, but only this one from Amazon worked with my Toshiba. Mine works very good with about twice the battery life compared to the original battery, but the computer does not sit flat anymore though. I ususally don't power off my laptop, just close it when Im done. The power charge lasts about a month or so, but I use the laptop infrequently.Did you:1. Make sure the battery is inserted fully and correctly?2. Charge overnight.3. Are your power cords working okay?4. Are your electric outlets okay?5. If you disconnect the power cord, does your computer stay on by battery power alone?Good luck with the batteries.

I found that mine won't charge at all when connected to my computer at work. It DOES charge on both of my home computers, and I did install the Creative software on those computers. I e-mailed Creative's support to inquire if the software was required on a computer for it to charge the player, but I've heard nothing back from them. Since then, I've bought a second battery (non-OEM Lenmar battery) until I can find a reliable and inexpensive A/C charger (this also means non-OEM since Creative's prices are nuts).

I guess I am the odd man out in this one. I love mine. Works good. Are you sure you got a good charge? When the unit is charging you get a visual indication on the screen that it is being charged. If you do not then maybe the connection to your power source is not seeded correctly. I plug mine into a usb port on my windows7 desktop, it recognizes it and starts charging right away.

Mine came with the 90 Watt power adapter and the power cord, although the same adapter and cord that I already had with the ThinkPad notebook would have also worked with the dock. These docks are no longer being made or sold by Lenovo, so they are either leftover old stock or refurbished, and are being provided by third-party sellers. Mine came from a different seller than the one Amazon is currently showing, so I think you need to contact the listed seller and ask them the question directly (if you click on the seller's name in Amazon's listing, it will take you to the seller's page where there is a "contact seller" link).

If this is an old battery replace it. If this is a new replacement battery, my guess is defective battery, because charging must be working. Laptop works until charger is unpluged.

I purchased as a gift for my son at Christmas, he's had zero issues. Once the battery is fully charged, disconnect. Removing the connection from the laptop when finished using would prove ideal. Keeping it connected kills the battery much more quickly. Contact Philips or Batteries Plus is a great place to look. Hope this helps and good luck.

Verify you are using the properly rated amperage adapter. Verify the battery isn't overheating. Another thing to try is to shut the laptop down then try to charge. I have purchased a number of anker batteries for client's laptops and have had excellent results!!The last thing to verify is that your laptop identifies the battery in the bios if your laptop supports it.

To really see if the battery is really "full", I'd unplug the AC charger, wait 30 seconds, then push the "battery test" button again. If it still reads "99%", the battery is really charged. If it goes to "65%" or such, then it needs more.I base that on having got one and when I first plugged it in, it instantly began flashing "FL". However when I unplugged it the display instantly went to 10% or such showing that the battery was resisting the charge and the "FL" reading was false (just coming from the chargers power only while it was plugged in). So don't be fooled into thinking it's full that fast, yet 5 hours is a lot more than under 5 minutes (where it may have taken in some power, but it may still need more).

I checked with my daughter, since I bought it for her laptop and she's the one who installed it. She did not get that message, but did mention that the battery needs to be charged before it will work. I don't imagine it would charge, though, if it's "not detected", but maybe you could leave it on for a while and see. You can probably tell I'm not very "techy". We didn't know until after we bought the battery that the laptop would work perfectly well just plugged in, with the battery uninstalled. If I'd known that, I probably wouldn't have bought the battery at all. Sorry I can't be more help. I checked with my daughter, since I bought it for her laptop and she's the one who installed it.
