I have two batteries, both of which will charge in my inspiron 4000, but not in my inspiron 4150(in which i recently replaced the motherboard with one from a c640, they're identical). If i charge a battery in the 4000, I can use it in the 4150, and it will report the correct charge amount and everything, but when I plug in the AC adapter, it says "charging" but never actually charges the battery at all. The lights on the side of the computer for "on","battery",and "charge" don't function, i'm not sure if these ever functioned after my motherboard swap.
About a week ago the 4150 worked fine, i had bought a new battery off of ebay and when i put it in the 4150, it would charge but wouldn't read the percentage, it would flicker on and off between 'no battery' and 'charging'. I sent the battery back and he replaced it with one that works fine, but now my laptop isn't working.
HELP! i'm afraid that bad battery short circuit my charging system.
Thanks
