Thinkpads Forum

My google fu is weak when fighting against the forum search style, so I apologize if this has already been asked somewhere.

Back in 1997, during my first semester of college, I decided that I needed a laptop. I found a TP 755Cs for just under $500 which was a really good deal in my local market at the time. That machine never gave me any trouble (until it lost the ability to remember the time and date, but that's a problem for another time). In 2001, I upgraded to a 600E (never even considering a non-ThinkPad after my 755Cs experience), but I kept my old machine as a backup -- using it occasionally to take notes when the 600E was being configured to school specs, and to play old games on.

Sadly, the 755Cs has lain dormant since 2004; and when I examined it the other day I noticed a foul odor -- which I think is the battery that has finally died (it worked well, holding a 3 hour charge up until 2004). I need, therefore, to remove the battery.

Simple, right? Well, not exactly. I know it sounds silly, but I've only ever removed the battery once; and that was an accident many years ago, so I'm not really clear on where it is or how to remove it without damaging anything. I am reasonably sure (thanks to my foggy memory of doing so) that it slides out of the side, and I think I have located a panel that can be removed in the middle of one of the sides, but I cannot budge it with even moderate pressure. I need to find out if I am on the right track before continuing -- I don't want to damage it (if the battery hasn't already). Does anyone have any instructions?

Thanks in advance.

You have to open it up, as if you are going to turn it on (ie. lift the LCD). Then using the same sliders to release the LCD, you have to pull the sliders just a little further, and then the keyboard will lift up.

There should be a pull tab to lift and remove the battery.

Thanks... worked like a charm. Unfortunately (or actually fortunately), there is still nothing wrong with the main battery. It is dry, cool, and looks like new. Which leaves me with a new dilemma. There is a Ni-Cd battery under the floppy drive. If the sticky/burning substance is coming from anywhere, it's there (it corresponds with the spot it keeps appearing on the bottom). Any suggestions about how to remove it safely?

Again, all advice is deeply appreciated.

Glad that you got it open.

I guess we'll have to call on AlphaKilo470 to answer this one. These machines are almost identical to the 760 series that he adores.

Alpha?........

If I'm not mistaken, the battery is either under a flap of plastic or in a piece of plastic. The maintenance manual (listed in the FAQ) will give full instructions for removal but easentially, it just comes down to doing whatever gets it out without breaking anything. I'd reccomend gloves if you don't want the corroded material to get on your hands. If I'm wrong and/or not enough in-depth, Leoblob might be able to help since I know he has a 360 which is similar in layout to the 750 series.

Thanks, Alpha.

Please tell me you aren't referring to item 8 in the FAQ... because I have already searched those links and didn't find my computer's manual... but then, I am notorious for not being able to see things that are right in front of me.

There isn't a HMM perse for the 755CS. Go to the link in the sticky at the top of the legacy conference. Once the link is open, go down to "mobiles". Once mobiles is open, search for 755cdug.pdf. This will be a user manual. I didn't get to look all the way through it to see if the CMOS battery is covered, but there is a ton of information in there, since the CD and the CS are close to each other.

Thanks. The manual is very informative, and I appreciate it. Unfortunately, although I can see where the CMOS battery is in one of the diagrams, there doesn't seem to be any information on actually removing it. I may have to just try trial and error and hope I don't break anything.
