I wired an old secondhand Dell charger (that was making a funny noise when charging), to the laptop 19v output of a RocketSocket charger. It works great, but there's one problem... it shows charging, the battery doesn't go down, but it doesn't actually charge the laptop battery, and when I start up the computer it gives that infamous adapter not recognized message.
Now, I suppose I could cut open the charger and wire the chip to the third wire, but I think that may be a bad idea because according the the instruction sheet, the RocketSocket outputs 12/16/19V - 2/3.5/3.5A output. The secondhand Dell charger shows output 19.5v 4.62A. Do I risk overheating or damaging the RocketSocket laptop charger or the Dell by faking a more powerful adapter's chip? Or can I reprogram the third wire's chip to set the correct expected amperage?
