Resetting Li-Ion battery IC

[pietersegers]

Hello,

As some of you might know Li-Ion batteries have electronics in the battery pack in which the battery condition is stored. If you repair your old and bad Li-Ion battery for example by replacing the cells you have to reset the IC which remembers the 'condition data' as well. Otherwise your computer will still think your battery is bad.

I have that problem now, after 3 minutes of working my battery is down to 1% and 0 minutes remaining. But after that it still goes on for 1 hour (disabled all windows battery warnings).

Does anyone know how to reset the battery pack IC in general?

I have a fairly unknow Sky A320 notebook (Amd 1000Mhz).

thanks,

Pieter

Will resetting the bios do the trick, you can do that by removing the cmos battery, generally located, under the plastic cover containing the touchpad, on older laptop computers, do they have a website, if they do, see if there's a service manual available for download.

Hi and thanks for the input!

But resetting the bios won't help me there, since the 'battery condition data' is stored in the electronics in the battery pack itself.

Any other suggestions or help will be very appreciated!

During cell replacement, the circuit of the 'smart' battery may need to be kept alive with a supply voltage. Disconnecting the circuit, if only for a fraction of a second, can erase vital data and render the circuit unusable. To assure continued operation when changing the cells, connect a secondary voltage through a 100-Ohm resistor before disconnecting the cells. Remove the secondary supply only after the circuit is fed from the new cells.

Might be somewhat helpful.

Is it actually a lot cheaper to replace the individual batteries?, than buying a new battery, sorry about the bios thing, simply wasn't thinking. I've worked on enough laptops with these type of batteries, but never actually rebuilt any.
