I'm using T530 and it worked well. I don't know if it is compatible with W540.

No it is not. If you search this- DW054 battery, you'll find four from 20-60.00 each that you are looking for.Larry.

I have a Lenovo laptop and, for me, it was a compatible battery, not an original replacement. Still, it works better than my original did!

I think the one for the T400 is here: http://www.amazon.com/Laptop-Battery-Lenovo-ThinkPad-4400mAh/dp/B0083XOZIE/ref=sr_1_1

The Lenovo battery I purchased worked fine. But this has been so long ago I really don't recall any other details.

I checked the compatibility list of computers provided with the battery in the detailed description. You might search for replacement battery for your particular model in the search box.

My laptop is a N5050. It has worked perfectly for me. Better than my original battery.

You don't need 170W for the T-series; they only require 90W. The dock listed for the T540p is 40A20090US on the Lenovo website (find it under accessories for the T540p). I'd get the one specifically listed for the T540p to be safe.

I bought it for Thinkpad T-Series and it worked well with it. I am not sure about W-Series.

I'm afraid not since AFAIK, the optical drive on the ThinkPad T540p is fixed, not user-removable like the older models that adopts the Ultrabay technology.

I don't know about the laptop you are referring to. The battery works really well in the Inspiron M5030 which is the laptop I ordered the battery for.

I can't say for sure, I bought mine for a Lenovo R400 -7439W1K and it worked fine.What I did before I I did some extensive research on the lenovo support site. There you will find all the info concerning which battery is compatible with which model laptop. There are some types that fit more than one but you have to double check.

It appears to be similar to what you have already, should work just fine. I bought 2 of these for my IBM thinkpad but they just weren't compatible even though all spec's matched. Worst case is you may have to return and purchase a brand name that is on manufacturer's approved list. It is worth the try for the affordable price.

Sorry, but I have no idea ;))) I have purchased it for my W510 and it is working properly with it. :)))

Look at your current battery. If the model number starts with NP-FV, it should work. That is the battery type. The number after that simply represents the battery capacity and size. For instance, 950 is bigger than the 550.
