oldie toughbook for random computer torture

Truth and honesty are some of my best virtues, and vices....

But, I don't care what God (if any) you believe in. Call it kharma, or reaping what you sew; it does come back to you, I promise you that.

 

i competely agree, once you start doing these things there is no going back. how is that saying? kharma is a b!tch ? and even if i didnt care about my soul or how i am as a human being. how the hell do i stay in business if i start scamming people....

 

Can I get a witness!?

 

what do you mean? i dont get it...

 

Unless you have been exposed to religion in the US, especially in the rural southern states, you probably would not understand. It is one way of getting affirmation from the rest of the congregation. The pastor of the church will often times say it when he is giving a sermon.

 

Hi
my CF-M34 has an almost dead battery, it lasts only half an hour. I've found out this article about replacing the cells:
http://toughbook.wikispaces.com/CF-M34+battery+re-cell
It seems to be possible, so I ordered these for replacing:
http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=220546785563&ssPageName=STRK:MEWNX:IT
The cells are already configured in the right series/parallel setup, so it's only a matter of desoldering/soldering the wires. A suggestion would be to solder the new cells without disconnecting the old pack ( obtaining a parallel dual battery pack) and only after the new connection is made, remove the old cells. In this way the battery managing circuit will be always powered, thus not losting its setting.
Will keep you updated

 

I forgot this was an intl forum.

very accurate and concise description SilverTrooper.

 

Silver Trooper does have a Silver Tongue...

Many of the Panny OEM batteries cannot be rebuilt of they are flashing RED as the chip inside that "tells" them that they are dead. Unless you have the software to reset them... You are TU when it comes to rebuilding...

Sounds like you were lucky! Maybe not totally gone before the rebuild.

 

Batteries have significant internal resistance. Even when they're dead.

A dead battery isn't a wire, it's a resistor.

 

The information was correct, you just misinterpreted it.

The L7500 is a "drop-in, pin compatible replacement for the L2400".

What this means is that the L2400 equipped motherboards don't need to be re-engineered to accept the L7500 i.e. the chips are electrically identical.

 

now that you point it out i have a heard about that. although i've never been in the us. although i'll probably travel to new york this summer, but we'll see. havent decided wich city yet.

very well then. i hereby stand corrected. i'm pretty much self thaugh so there's bound to be some mistakes

 

Ares93:

I'm from New Jersey (that makes me a "yankee", like New Yorkers) but have lived in North Carolina (southern) and now in Virginia (depends who you ask as to weather or not Va is northern or southern)
Long, pointless story, short, if you're up north, you're gonna need to go to a primarily African-american church if you want to get the full experience of that nature. White northerners, generally, aren't 'moved by the spirit' as most southerners (of any color)(or denomination). Although, those types of services are way more fun to attend.
I was raised Roman Catholic... mostly very boring, monotone ceremonies, unless you include the aerobics (stand, sit, kneel, stand, kneel, sit, sit, walk here, kneel, stand, walk there, it goes on like that for the whole mass)


And it doesn't matter if it's a resistor or a wire (0 ohm resistor?): you run enough juice through it, it'll release the magic blue smoke... or worse.

 

yeah i know the aerobics. i'm roman catholic too. well if i'm there i'll probably check it out. religion have always interested me. but i dunno if a white european would fit in so to speak . anyways me and a few friends are probably gonna try out the student exchange program next year. i'm thinking san fransisco or somewhere in the midwest. recommendations are greatly appreciated.

 

I wouldn't even know, i've lived on the east coast my whole life;
I do know that there are a great range of cultures here in America, and depending on where you go, depends on what you'll see. Go anywhere, it'll be interesting regardless.

 

I do not say this to re-debate the Civil War, I regard it as the blackest time in American history, when truly "Brother killed Brother." On the other hand I hate "Revisionism." Those that do not know history, are doomed to repeat it.

Anyone that does not know that know that Virgina fought on the side of the Confederacy is ignorant. West Virginia d id not. You can not change history by wishing really hard.

My apologies to the rest of the world that reads this board that most likely could care less either way.

 

Humbly, I present to you all that the 'truths' that are taught, and the truths that are learned, end up being completely different from one another.


And that's all I've got to say about that.

 

...and you can not tell which way the Train when by looking at the tracks.

But that does not change easily proven history either.

 

now i dont mean to be disrespectful or anything, i know the civil was is a sensitive topic with you americans but what the hell does it have to do with any of this?

i talked to Silver about this but still i cant get it out of my head. i saw this cf-27 hdd caddy for $0.99 and i'm thinking of buying it. i've got silvers CF-28 on the way and i though it'll make a splendid project to mess around with. i know it wont fit plug and play but i was thinking of modding it. someway its gotta work (the hammer is your friend ). if the connector itself (ribbon cable) fits i could reverse engineer the parts. ducttape and superglue can make anything work anyone tried this before me?

 

OK guys... it works! I've just charged the new assembled pack and everything seems to work the right way. After a few cycles the battery will reach its better performance. It is now 5000mAh against the previous 3400mAh, this should give a boost to the autonomy of the 34.

 

Build me one!

 

Nothing, it is like all communities, not matter what their original purpose, there will be digression from their founding purpose from time to time. Those boards that have ignored this, ignore human nature and ultimately go dark.

I just find it annoying that someone could be to ignorant as to claim that somehow that Virginia fought on the side of the Union when the capital of the Confederacy during the American Civil War was first Montgomery, Al, then Richmond, Virginia.

 

Well,
there were many northerners mad at southerners in va, and many southerners mad at the northerners in va (northerners were there because they were in the govt). I didn't come across as I had intended.

A)I don't think there is anyone that could dispute that the civil war happened, and that it was a bleak period, but one that ended up strengthening the country (ultimately)
B)There are many people who debate the loyalty of the people in va, not necessarily the state itself. It's kind of a running joke as to where the Mason/Dixon line is actually located.

Although, I have noticed that to northerners it's called the civil war, but to many southerners, it's "the war of northern aggression".

Back on subject;
ToughHog - congrats! your success has granted me hope. How dead was your battery before the swap?

to anyone else: is there a known signifigant difference in the components, logic, or "programming" of the cf-m34 and the cf-29 battery packs?

 

well i guess the american history classes in sweden arent as accurate as you'd think. i was thaught only montgomery was the capital.

i think you underestimate what you can debate. i know people who claim the holocaust was allied propaganda.

 

The battery was showing 1:30h, but in reality after about 30 minutes the nb was dead! As you know the discharging curve goes down steeply near the end of the discharge, so what we read is not the real value.
A strange behaviour anyway appeared after the cells swap: the internal circuit don't recalibrate itself. It tends to "remember" the old capacity, but the computer will not shut down even if the gauge shows zero capacity. In fact I managed to keep it alive for more than three hours after the battery meter told me there was no more juice!
I'm looking for a method to recalibrate the readings....

 

There must be a way to blank or reinitialize the circuit, or perhaps a way to eliminate it altogether? Does there look to be a Prom or a MicroP on the circuit where the data could be stored?

 

whats the achillies heel of circuts? like a harddrive and a strong magnet. there's gotta e something

 

A picture of the circuit in question would be most helpful...

 

i'd post one if i could but i don't have the battery yet. anyone have access to one?

 

Ok, good news Sometimes we discard the most obvious solution: I ran the battery calibration utility from the BIOS and... voilà, the meter shows between 4:30 to over 5:00 hours of autonomy depending on the CPU usage
It took a whole night to calibrate... just followed the BIOS instructions.
Hope this helps

 

actually i both does and doesnt. it works sometimes but way far from always. you got lucky, thats it.

 

We need to figure out what's on the board to figure out how to talk to it.

A great place to start would be some pics, and of course the bios. The bios will contain some of the info/code needed to at least help figure this out how to communicate with the battery, and possibly how to reset the circuit.

gotta find some pics.
