Hi,
I'm writing from a Gericom Webshox portable computer of 2001,
now the battery pack ( UN241S1 Rechargeable Li-Ion Battery Ratings:
14,4Vdc 3600mAh )
is broken son I decide to change the accumulators,
I choose 8 NiMH 3,6Ah 1,2V Accumulator.
After the substitution it still doesn't work, the charge seems to be
ok,
also is I do not understand why is used a 14 Volt supply to charge
battery pack to about 5,8V

The discharge phase is not ok, the 5,8v coming from the accumulators
seems to be blocked
in one of the two printed circuits comprised in the battery pack, so
my questions:
1) What is the job of these two circuits?
2) It is possible to connect directly the accumulators to the output
bypassing these circuits?
3) What the white, yellow and green wires are used for??
4) where I can found a scheme of a typical battery pack ??
5) why the supply is 14v to charge a 5,8v battery pack ??
Hoping in your help
many thanks ...

Can't tell exactly what you're trying to do.
I can say that you cannot replace lithium batteries with NiCd and
expect the charger to work. If there's a protection chip, you can't
expect the discharge to work either.

you cannot charge a NiMh pack from a Li-ion charger two totally different
things a Li-ion cell is either 3.6 or 3.7 volts a cell a NiMh is 1.2 volts a
cell so for the same number of cells you only have 1/3 of the voltage and a
NiMh charger is a current based device and a Li-Ion is a voltage charger
just lucky you tried it this way as charging a li-Ion pack from a NiMh
charger and your laptop would be toast?? have a look here and try again
