vostro 1720 battery not charging
Windows XP, I am using a Rayovac COM20077 19.5V 90W charger with a Royovac COM10403 14.4v 5200mAh Li-Ion battery. This has worked for at least a year and recently, the battery stopped charging. The laptop will work as long a I plug in the power chord. It will work with only the battery except the battery will discharge to "dead" because the it will not charge. Interestingly, the when I plug in the charger, the green battery light comes on for about 3 seconds then goes out. Likewise, the battery "power meter" shows battery charging for about 3 seconds and goes out as well. I have tried two "new" batteties and a dell charger; nothing will make the battery charge. Any ideas? Thanks, Harvey

Check the BIOS setup (F2 at powerup). Is the AC adapter recognized, or is it listed as "unknown"?

It says: AC Adapter Type, None.
Bios Version A04
Thanks for the reply. Someone spoke of using Fn-F2 and Fn-F3 to turn on/off the battery charger. At any rate, I tried this and nothing happens.

First try: a new OEM Dell adapter. If that too isn't recognized, replace the DC jack:

If that fails to solve the issue, replace the mainboard.

That's the next suspect. Replace the DC jack -- if that doesn't solve the issue, it's a bad charge circuit - meaning a mainboard replacement (which given the 8-year age of the system, likely isn't going to be a cost-effective repair to do).
