Is there a way to tell if my Dell laptop battery charging feature works? I have two batteries; one is almost new and both are completely dead. I put them in the laptop and leave it "ON" for days and still 100% dead. The only way I can use this laptop is through the AC power cord.

On top of this, the voltage regulator in the AC power cord also shuts off at times therefor it shuts off the laptop.

Thanks

That's not good. Sounds like it's overheating

I'm having similar problems with an ASUS laptop. Turns out the pins in the AC adapter got bent and weren't making contact when I plugged it into the laptop. My laptop was still under warranty at the time, though, so I was able to get a new one shipped out to me. However, my laptop sat uncharged for a few months and now my battery doesn't charge. You may be experiencing a combination of these two problems. That would be my best guess.

You may want to see if Dell will send you a new adapter, if it's under warranty.

I see 2 possibilities here:
1) the batteries are fried and won't hold a charge.
2) the power from the AC Adapter isn't getting to the battery

I don't know of an easy way to tell if the battery will take a charge, nor an easy way to tell if the connection between the AC Adapter and the battery is faulty. I'd suggest taking it to a local PC shop that works inside laptops - they may have some testing equipment that can provide answers.
