Should I run the laptop without the battery if on ac power?
Or will doing such damage components inside the t400?

I agree. No bios flash needed. I think everything is working fine, so I am not taking the risk of creating a piece of post-modern art entitled "The Brick."

I have the bios 1.13 for the T400. I do not know if I should attempt to flash the bios and things to upgrade it to the current release. I am afraid of bricking the machine.

Any thoughts?

How safe is it to flash the bios?

I purchased a T400 a few weeks ago, and I have finally purchased the requisite hardware for my upgrades. I am installing a Momentus XT 750gb hd and 8gb of ram. I would like to know how much of an improvement in heat control I would get if I apply MX-4 for the thermal compound, because the computer g...

16GB (8GB x 2) DDR3 PC3-10600 Unbuffered NON-ECC DDR3-1333 1.35V

From KomputerBay??

The PC3 part is different, but the it is the same PC3 that crucial says is compatible. I read the other thread as well, even before I posted this.

Is it possible to install 16GB of ram into a T400? I know that you can install 8GB in a t61, which is only supposed to take 4gb.

well, I just went through crash heaven. I have no idea why? but it could have been the hard drives being swapped. Joy. The problem I am faced with is the COA is unreadable. I tried asking lenovo, but they were less than helpful. And, MS has been the same. MS said that the 32bit was OEM and married t...

Yes, my ideas may not work. I was thinking of actually switching the physical hard drive. I was hoping the lenovo partition on from the t400 hard drive would come on.

I just bought a T400 off ebay. It came with Windows 7 pro 32bit. I have Windows pro 64bit on my T61. Is it possible to use the T400 recovery disk on my T61, so that the 32 bit OS is on it, and then install the 64bit onto the T400.

It is crap. I have uninstalled it. Thanks for letting me know..

I am trying to disable the back and forward keys. And, I am an idiot. I downloaded the program, and I couldn't get it to work, so then I downloaded a whole bunch of crap trying to figure out how to use the thinkvantage things. I ended up with a toolbox and whole lot of other crap. I figured out what...

I have a t61, and I would like to use a program called (or about) key customiser. I downloaded the software, but I don't know how to access thinkvantage.

So, I paid too much?

I saw the links you provided. I appreciated them.

i paid 340. it is still under warranty. one owner machine, owners manual included, and some other oem things. It comes with everything I listed. I have the t61 (with fan trouble, I am running tpfancontrol) it does ok, but I wanted to get a machine that could have 8GB of ram. It is a little faster, a...
