Hi ivydream, the T42900 has an Widespread Oscillation feature, while the 2554, this feature is optional, default configuration, does not have that feature. Thanks, PCrush

S-9888 fits my 0394M 4QT just fine. I believe (but I am not sure) that the difference is, 9899S had a soft plug (center) made of lead, which is no longer used. The S-9888 has metal body with a synthetic soft plug.

I have a different model of Samsung. So I don't know if the battery will work with the t259. Your owners manual should tell you the type of battery you need. If you don't have your manual, check on-line on Samsung's website. I hope this helps.

The difference is color. One is full black, gb35452 is gray-blue, gb35380 is black n blue.

I honestly don't know. We have T420 and T430 machines. They are compatible with those T4XX models. I hope this helps.

Sorry but I'm not know exactly the difference. I had this model and it works very well.

I have previously owned a T43, and the last one is a T61. The W530 did not have an SSD however I cloned the 500gb drive and installed aMicron ~900GB drive in it's place, W7 boots in seconds! run time on batteries is an easy 4 hours with little power saving turn on. The only thing I do not like: No caps lock led. I use it for engineering work and normally have it on a dock, However it still many times faster than the T61 while on batteries.

I don't know. I am very happy with the 837409 and didn't compare it with 837450.

According to Lenovo's web site, the 43 battery will fit the T420S. By the way, it's an awesome addition to the laptop, at least it has been for me. Nice traveling coast-to-coast and not worry about aircraft in-seat power.

My read of the customer reviews supports the notion that the 255W is a terrific unit. Thanks for your reply.

Hi, the U6439 is, about twice the price. So is the U6485900, only about $50 more, but doesn't look like its as much of a machine.

It looks to me that the only difference between 024us and 020us is 020us comes with 1)Bluetooth and 2) 802.11n, while 024us has no bluetooth and only 802.11b/g.Check this out:http://www.msimobile.com/nblist.aspx?series=U120

Ask them to look for either A0911 or H2511 stamped on the bottom of the packaging. A0911 is for the first version; H2511 indicated the second version. Hope this helps.

10164 is a newer version. There appears to be a slight color difference. *shrug* I bought the one that was cheaper and it does the job.

I am not sure why the discrepancy. The model number on my computer was BHI7N11.

I believe all of the models share the same parts. the best way to know for sure is to compare the one your trying to replace visually with the one you are looking at. Voltage and hardware in general will be the same(for this model) its the os or memory that change. Sorry I could not be more helpful.

Well judging by my last purchase from Datasales co. I bought a t40 and t41 refurbished with xp in January 2010. The T41 is still chugging along saddly the t40 finally gave up last month. Both have been survivors of at least a dozen falls. That is why i just purchased this t400.
