-   Dell D510 won't charge via AC adapter--tried multiple adapters and all work on other Dell 505. However, D510 will charge battery when in port replicator? How do you correct AC adapter port?-   Guest Mar 21, 2009
-   My laptop doesn't charge. Whenever I plug it in, it says "on AC Power" but doesn't charge. Do I need a new cord? HELP!

-   Dell Latitude C500/600. CPU claims battery at 0% and charging. Never goes above 0%! Bought a brand new battery -- same problem. Updated BIOS A23 (no need; was already on anyway). Same problem. Pressed battery charge indicator buttons on battery and battery is fully charged. Tried to update BIOS A10 (because A10 claims to solve a dual battery/recognize problem) but when running, it asks to plug in batteries and AC adapter! Yet, everything is plugged in. This tells me that the CPU is no recognizing the batteries for some reason, though the batteries seem to charge and the CPU has no idea -- "0%, Critical, Charging." DELL SEEMS TO BE OBLIVIOUS TO THIS, EVEN THOUGH 100s IF NOT THOUSANDS ARE HAVING THE SAME OR A SIMULAR PROBLEM! Fun stuff. Don't think I'll buy a Dell again.

-   i have the same problem as the first post. i am an experienced electronics tech with 50 years experience, and am not often fooled by electronics items i work on but this one has me guessing so far. my battery computer a dell d600 were all working fine running 3 1/2 hrs plus on batt then one day it just told me to charge the battery as normal and it wouldnt change when plugged in. i checked the battery found only 3 v on two pins but not referenced to the power ground. after reading extensively about dell making the charger stop charging the battery after 500 charges, i opened up the battery housing just a plastic shell around the multiple battery cells and two circuit boards, and found as i expected a full 11.3v on the battery cells, but the circuit boards report 0v to the computer. someone said disconnect the 3 v that powers the kill circuit in the battery and it will reset and work. this didnt work. so i bought a battery no help. so i bought a charger, both originals of proper voltage wattage etc, no help, so i bought and replaced the charger connector, and the co,mp[uter seemed to try to turn on, so i cleaned the oxidation off the ram edge connector pins and the computer came up and ran for about an hour fine and i foolishly thought i was home free, well home for about $55, actually but you know what i mean. but iut only ran for an hour on the new battery that showed a full charge at the start, but id never charged, and the computer started flashing the warning to plug in to avoid loosing my work. i jumped up grabbed the new charger and plugged it in confident it would charge. you guessed it. it wouldnt, and shut down. so now i have two batteries the computer pretends are dead but refuses to allow the charger to charge and two chargers. so i recalled someone saying the computer would run off the charger so i tried first the new one without the battery then the second charger without the battery no dice. so the interim result is dell over $400, me zip. but i havnt given up yet. anyone whos more experienced on dell laptops than i have any ideas i havnt tried? im at a loss at this point. this is my first laptop i actually bought it for a grilfreidn for christmas and its beginning to look like ill be in the dog house christmas day cause i declined top buy her the $2000 one she wanted, and bought this one confident i could do the maintenance on it if ever needed. and its needed nothing but maintenance since i bought it. i replaced the cooling fan that quit and cleaned off the hard dry yellowed hard silicon heat transfer grease on the micro and other chips requiring cooling, and replaced it with new fresh soft white silicon heatsink compound before when it quit, and thought it was ok. ran for two months before thjs series of power related problems. dell is trying to whip me thats what keeps me from giving up, i must defeat this inanimate object, its no longer about breaking even on money or saving any. i almost feel like replacing the mother board on a computer that works fine just because i cannot get the 11.3 volts from the adapter connector to the battery due to dells engineering desigend to confound the tech. id bypass the shutdown circuit and run the positive voltage directly from the charger to the battery but there are, completely unnecessarily, 8 pins on the battery masked by the connector and no info on where the 11.3 volts should be applied. ok the voltage isnt 11.3 it can be from 11.1 to nearly 20v from the charger and be ok but the batt says it should be 11.1 and the cells inside measure 11.3v. ive searched till im blue in the face for a schematic and if i could find one id fix it, but there seems to be none available anywhere. if anyone has the information needed, that is where does the p[os voltage connect to the battery ill solve this problem, and try to help others but i cant locate the information. this is a seemingly very simple unknown, but its enough to thwart me. guess ill go back to the battery i opened and try to solve which pin it must go to but it isnt direct it goes through two circuit boards controlled by 3 volts picked out from some of the middle battery cells. however i also have the delima that my computer wont run off the charger with the batt disconnected. if it should maybe thats where i need to start, to try to get the charger voltage to reach some point where its needed in the computer. that may solve both problems. -   Guest
