I have an old Dell Inspiron 8200 which is in good working condition except for the laptop's (inner) converter that is responsible for using the power supplied by the laptop's AC adapter, using it to both charge the battery and to power the computer while the battery is in. This is a known issue with this laptop model that has caused problems to a lot of people once these laptops start getting old.
Aside from the laptop's original AC adapter (with an output of DC20V 4.5A), I also happen to own another high quality AC adapter (from another laptop long gone), which happens to have the exact output as this laptop's battery, that is, DC15V 4.5A.
Now, what I would like to do is to bypass the faulty laptop's (inner) converter (that is, the problematic circuitry inside the laptop), get rid of the laptop's battery (which does not work anyway), and connect my quality DC15V 4.5 AC adapter (which as I said provides the exact same output as a fully charged battery for this laptop) directly to the battery jack inside the laptop.
Basically, this way, the laptop will "think" that a fully charged battery is in. I've tested it with another working battery from the repair shop, and the laptop works perfectly fine with the power supplied by a battery inserted in the battery jack.
However, I am not sure to which two out of the six or seven battery jack connectors (of the battery jack inside the laptop) I need to solder the + and - output wires from the DC15V 4.5A AC adapter (actually, I will not solder the output wires from the adapter directly to the battery jack, but will make it unpluggable, for convenience/safety reasons).
Could someone who exactly understands what I'm talking about here please provide some directions in this regard? All I need to know is which (two) battery jack wires I need to connect the DC15V 4.5A adapter output to. Thanks.
