Is there a way to callibrate an A22m battery?
Hello!
I bought my "new" (well, new for me) ThinkPad A22m with a working battery, if I uninstall the power management stuff it lasts 2 hours and a few minutes, but if I leave it installed it lasts 6 minutes and then it goes to standby and it won't woke up until I plug it in to AC power
I tried completely depleting the battery and charge it back up without turning it on 3 times so far and no change
Any ideas?
Greetings,
Ricardo

Re: Is there a way to callibrate an A22m battery?
I'm not really comfortable working on a laptop without a power gauge lol
The cells are fine, maybe the battery controller is messed up because it hasn't been used in over 15 years?
edit: I can get it out of the weird suspension mode again with the power management stuff if I press the power button and connect and disconnect the charger, which is obviously not ideal, but there's plenty of juice left! Tried with 98SE, 2000 and XP and it's the same :/

Welcome to the forum!
First and foremost, I love your user name...
1) You'll need a Power Management Driver appropriate for the system and OS used
2) My guess is that you'll also need IBM's "Battery Maximizer Wizard"
3) Hotkeys
4) Graphics card driver
You may or may not need another utility to get everything going. For that machine, I'd suggest W2K, but you can get away with XP.
Good luck and keep us posted.

You'll have to do some digging, use the "Drivers" link at the top of the page.AHardDaysNight wrote: ↑Thu Sep 27, 2018 10:21 amI'm not really comfortable working on a laptop without a power gauge lol

Re: Is there a way to callibrate an A22m battery?
I tried installing the Hotkey application and the computer hangs
All the other applications and drivers installed fine through, Battery Information says the battery capacity is 5.04 Wh, but I don't know if that's correct or not... meh, it detects a battery at least
I'm surprised at the screen of this thing, it looks great and it's really bright! (sadly it's the 800x600 screen)
edit: it's been three minutes since i unplugged it and it went into standby i'll try again with the "When the alarm goes off, the computer will:" setting off and see what happens!
edit2: It lasted a lot longer, but on the final 40 minutes it kept saying it had 0%

That's what happens to old Sanyo batteries. Their gauge accuracy is even worse than their actual degradation.

Re: Is there a way to callibrate an A22m battery?
If "Battery MaxiMiser" can't update it, I think nothing will be able to.
Edit: if you can live without being able to set battery tresholds, get a BatteryBar application and check what it says. Works for me in my non-tp systems.

I took some pictures of it: https://imgur.com/a/MT6TMYu

edit2: i installed BatteryBar and it's discharging right now, it will take a while

I'll try that on a couple of hours and i will edit this message with the results

I don't think A22m generation supports threshold anyways.

You might be able to reprogram the IC on the A22m battery to be full again and see what happens.
Thinkpad4by3's Law of the Universe.
The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

That's interesting, I have another A2* battery laying around that lasts 20 seconds, I can recell it and probably reprogram the IC...Thinkpad4by3 wrote: ↑Fri Sep 28, 2018 10:00 amYou might be able to reprogram the IC on the A22m battery to be full again and see what happens.
turn on the soldering iron!

Get the data from the chip for stuff like measured capacity so you can reverse engineer the chip code.AHardDaysNight wrote: ↑Fri Sep 28, 2018 11:14 amThat's interesting, I have another A2* battery laying around that lasts 20 seconds, I can recell it and probably reprogram the IC...Thinkpad4by3 wrote: ↑Fri Sep 28, 2018 10:00 amYou might be able to reprogram the IC on the A22m battery to be full again and see what happens.

Re: Is there a way to callibrate an A22m battery?
ehm, I opened it up and seems like M61040 is what we need, but I moved not so long ago to Merida and I can't find my SMD tinkering stuff
I guess I'll stick with the working battery for now, Battery Bar really helped! (it's way more accurate than Windows)
aaaah
