It seems my IBM Thinkpad's CMOS battery has died, and it's know that
it won't boot wihtout it.
I don't have time to wait for a new one by mail, plus I have some
CR2032's in my fridge. The flat things that look like litttle
frisbees.
The current one has the wires connected to metal tabs stuck (welded?)
to the battery on both sides. Is there a way I can do this without
exploding or otherwise ruining the battery???????
I see that Radio Shack has a clip that holds such a battery but I
think it's too thick to fit. I just tore apart a 16 year old
computetr to get it's battery holder, but it was defintiely too thick
(Does anyone want a kit to make a 16 year-old computer?)

I didn't think solderign would work, but it occurs to me that
somewhere I have a mini torch, with one or two little tanks of gas, 2
or 3" tall, that is supposed to get very hot at a small place. Maybe
I could solder the wires to the battery with that???

Can you confirm that the Thinkpad manual nowhere says
whether and how to replace the battery?

I've done it (in a pinch) with the silver defroster grid repair, or
silver Printed circuit repair pen to make the contact, backed up with
a chunck of appropriately sized shrink tubing to give mechanical
strength.. It is NOT robust - but works in a pinch.

They use spot welds for a reason. A spot welder wouldn't
do nearly as much thermal damage to the CR2032 as soldering would.
It would probably ruin whatever functions as a separator between
the two halves of the battery.
None of the datasheets I've downloaded for CR2032, list short
term temperature as a parameter (like whether it could support
a solder profile). The max operating temp is listed as 60C or
70C, which isn't nearly enough for soldering, even with low
temp alloys. And the cell surface could be stainless, meaning
you'd need a solder that "sticks" to that stuff. If the solder
had a bit of silver added to it, that would probably push
the melt point too high.
You could think a bit more creatively than that. For example, how many
"holes or storage spaces" are currently available or unused on the unit.
Perhaps you can craft a 3V source, using a couple regular dry cells.
At Radio Shack, I could pick up a two cell holder, two dry cells
(1.5V each), then use the wire on the existing dead CR2032 assembly,
and solder that wire to the tabs on the plastic battery holder. It's
just a matter of routing the wire inside the laptop, using any
available holes. The battery pack would hold you over until the
new CR2032 assembly comes in the mail.
You could build a regulated circuit to run off the main battery,
but then, if left that way, you could dangerously discharge the
main battery. Some battery chargers will not charge a laptop
battery, if the battery ever heads below a certain threshold.
I think it's slightly safer, to just build a battery source
using dry cells.
Have you ever tried to find a 3.0V output three terminal regulator
in town ? That is probably a mail order item as well, and will
take just as long to get here, as the pigtailed CR2032 will.
The battery holder and dry cells, I can think of two stores in
town that can provide them for me.

The connection tabs on such cells is done with a specialized spot welding
machine which avoids excessive heating to the metal which will at the very
least shorten the life of the cell, will sometimes kill it entirely, or
sometimes yield a nice explosion (especially with lithium I suspect).
Hmm,
Look hard you can find a battery with soldering tab.

Hi,You can find a battery with soldering tabs. I am a LONG term TP user.

Except to maintain date and time. The machine will run with the wrong
date and time.
Lacking a battery, one can enter the date / time or hit the enter key
to skip it.
POST is coming from the EPROM - battery not needed.

Some machines will not boot with a dead battery in place, but will, with
the battery removed. Not familiar with Thinkpads, so not sure if that
applies in OP's case.

Perhaps you might cannibalize a suitable socket assembly from an old
discarded motherboard and attach wires to that.

(Googles, to look at a picture)
I'd order the proper battery, but to tide you over till it shows up,
just cut apart the shrink wrap on the old one, and cut the wires as
close as you can to the tabs, or actually cut the ears off the tabs. You
want bare metal showing on the end of each wire. As best you can, tape
them to the new cell from your fridge, making sure to keep polarity
correct. Gently put it all back together, and try not to bang things
around till the new battery shows up. This is not a high-current
application, so as long as it is good metal-to-metal contact, and
nothing shorts out, it should work.
Of course, all this only works if you have enough slack in the leads,
otherwise you would need to extend them.
I have done home-brew laptop CMOS batteries like that more than once.
Some ended up being permanent fixes, since the correct part was not
available, or cost more than entire laptop was worth.

There are a LOT of sources for the lithium button cells with wires
attached - with the wrong plug ends on them - in most major centers.
Most electronics supply shops or pattery specialists will have one you
can cobble the correct wire end onto

Just got rid of 3 370s, two 700s and 3 or 4 600s (Es and Xs) within

On a TP it IS. If the CMOS is invalid, many TPs will NOT boot -

NOT true on many of the early TPs.. At least one of my old 600s (E
or X, cannot remember which) would not boot at all with a dead CMOS
battery, and IIRC the T43 would not either. Had to replace the CMOS
batteries on a few to get them to boot.

The ones that will not boot with a dead battery won't boot without
one either (we are talking CMOS battery - not main power). Some bad
main power batteries WILL prevent the system from booting - and
removing THEM will allow the system to boot. Common on Toshiba A100s,
among others.

But I don't buy stuff just anywhere :-)
I bought coin cells at the mall, from a "battery store",
and they were flat in a matter of days. I'm a little
more careful now, where I get stuff. I need to know a
shop has a good "turnover of stock", so I won't get
screwed again.
If some computer store here carried a pigtailed CR2032,
chances are it's been sitting in the shop window
for the last twenty years.
The same thing could happen with mail order, unless
the seller is big enough that their stock is fresh.
Hmmm. Too bad this is a "web only" item. I guess
it would hurt them, to have this in a retail store.

Hi,
eBay is a friend some times. I get all the button batteries from eBay.
I just make sure they are brand names.

You'll want to check if the IBM's lithium cell is rechargeable or not
because you definitely do not want to install a regular lithium cell
if the original is rechargeable.
Don't store those lithium cells in the refrigerator because it doesn't
help, and it's possible that dew will slowly drain them. The same
goes for alkaline cells.
I'd solder a flat strip of springy metal (brass, bronze, steel, but
not pure copper) to each wire lead and curve each strip slightly so it
will act as a leaf spring. Then attach them to the sides of the cell
and wrap the whole thing in heatshrink so those leaf springs will
maintain pressure against the cell.
If you decide to solder wires directly to the cell, and I wouldn't try
without practicing on something else, like 1" squares cut from a tin
can. First tin the wires and the sides of the cell separately. Sand
the sides of the cell, wipe with alcohol, apply flux (rosin), and then
quickly melt on some 60/40 or 63/37 tin/lead solder to it. Do all
this so the solder sticks really well and quickly. Use a 30-40W iron
because anything with less power may actually do more heat damage to
the cell by not melting the solder as quickly. Then quickly solder
the wires to those solder pads. Cover everything with heatshrink.

First VERIFY that the battery is bad.
Don't solder on it.
Rip the tabs of the existing battery.
place them against the new battery, being careful not
to short the two sides. Use tape to keep the - from
shorting to the plus.
Tape the tabs against the battery.
Wedge it into the laptop with some foam to keep pressure.
Order a proper replacement and install it when you get time.

We have two ThinkPads (T60 and a T61) and I gave an older T60 to my son, a few
years back. Of the three, only mine, the newest, has any battery life left.
Mine is just over three years old and my wife's is four. The kid's totally
died recently so has gone to the great bit bucket in the sky.
For work, I've had a TP A21 (the nicest of them all) and a T43. Each one has
gotten a little worse, particularly since IBM sold the business. There is a
very good possibility that my T61 is the last of the ThinkPads for me, even
though I get a rather decent discount on them. I have no idea what else to
buy though. All laptops seem to be junk.
Really, three years is about all you can realistically expect out of a LiIon
battery.

You don't have to. I bought all my ThinkPads and accessories online, using a
credit card.

Mine is almost always plugged in (docking station) but the battery still has
over 60% (ext.) capacity. My wife's is just about gone and I was thinking
about buying a replacement but the ThinkPad is four years old.

IBM hasn't made desktop or laptop PCs for at least five years (more like
seven).

I should have tried it with the battery out -- sort of too late now
(I should have read this post Saturrday instead of Sunday at
midnight)-- , but I found webpages describing the 161 and 163 error
numbers on a Thinkpad, at least some of them, and they all agreed it
was the CMOS battery.
In addition, I once had a MAC II, and though they are famous for being
better designed than PC's, the guy at the computer user group I used
to go to told me that they too will not boot without a good cmos
battery. And in the case of that computer, the battery was soldered
in, and almost everyone ended up taking it to repairman to be
serviced, JUST for this battrey. That's two levels worse than most
PCs. Oh, and apparently it was a secret back then that the battery
was the problem. So that's 3 levels worse. What he woudl do is
put in a battery holder for 2 AAA batteries iirc. so customers
wouldn't have to pay him a second time. Or maybe he was just talking
about his own computers and friends'.

Good to know. And it also means I didn't lose out by not reading the
previous post yesterday.

It tunrs out that mini torch I was talking about, Archer brand, from
when Radio Shack used the Archer brand, burned butane and micronox,
whatever that is.
And I had never read the manual all the way t through, and it was only
for brazing, it seemed, not soldering, and there were supposed to be
brazing rods, which my friend didn't give me. I have some for bigger
torches but I'm sure brazing the battery would ruin it.
So I tried soldering. When I was little, like 1`953,, I found in a
box in the basement, wiith electrical parts, two D-cells and a
lightbulb wired together. I think it had all been stuffed in a cake,
It might have been for my brother, because I surely don't remember it.
and my parents saved it all even though the batteries were long dead.
But the wires were soldered to the battery, and I thought that was
cool, so yesterday I tried to solder to the CR2032. Yes it seems to
be satainless steel and that certaiinly is harder than a D-cell 60
years ago.
So I used some separate flux to save time and heating, and a WEN
soldering gun, but it just didn't stick.
Also the battery was a lot hotter than I expected after I had tried 3
or 4 times, but it stilll read 3 volts and still says that today too.
So I bought a thinner coin batterry holder at Radio Shack today, for
1.19 but it's still not thin enough. (Maybe John McGraw's side
grabbing one will be thin enough, but i'm not buying anything else
until the rest of the computer works) So I used longer wires, and ran
them through the small crack where the CD drive slides into the bay in
the laptop, then applied heatshrink to the battery holder and battery.
And now it will start. It stil doesn't boot right from the hard
drive but it does start DOS from Hiren's boot CD
I'm learning a lot, and even though it's old equipment, it's as int
eresting as any computer stuff I've done in months.

LOL I did that. I destroyed a whole, probably working computer
yesterday must to get the battery holder. They sell them for 1.19 at
Radio Shack but it was 101 degrees yesterday, Saturday, and I didn't
want to go out. It was from 1995 and only ran at 200 MHz, and I got
it free and was never going to use it. I have an ISA card left over
and 3 of the next generation -- I forget their name. Plus some
other parts I'll probably never use. I don't think the case will fit
new mobos, so I made a little space.

f this would work it would have been a good idea too. Too late now
mayube, but this might have worked becaus ethere is some spring loaded
space between two pieces of metal where the battery goes.
I could have put a drop of sollder on each wire's end, so the wire was
thicker than the insulation.
This is the sort of answer I was looking for, among others, but there
weree so many answers, I didn't take time to read them all!!

Some would say that 9 dollars is more than the laptop is worht.
I spend 23 dollars on the 40 gig HDD, but I figure I can use that in
other laptops in the future.
That is, unless they insist on SATA or something.. I didn't think
of that when I bought it.
(Although just tonightt for the first time, someone on Freecycle is
giving away two laptops. And both are missiing harddrives. He
thinks they may also be broken. I don't know if he's going to give
tghem to me or someone else yet. I may not be the first to reply. )
