Replacing 11.1v 4400mah Gateway battery with 11.1v 6600mah
I have 2 Gateway T-1620 laptop computers. When the original 11.1v 4400mah
batteries went soft I replaced them with 6600mah batteries to give longer
off-line use.
Both laptops will charge either 6600mah batteries for a few minutes and
quit. If you uplug and replug power they will charge a few more minutes. I
can charge the batteries with a power supply set for 12.6v and 2 amp limit
as per manufacturer specifications. After charging they work properly in
the laptops but will not recharge after any battery use. I see a lot of
complaints about the Gateway chargers.
Does anyone have a schematic for the Gateway charging circuit? I suspect
it is software controlled but perhaps there is something I could do to
make it charge the larger batteries.
