Plugged in not charging - brand new battery

by Bunnie1978 / March 16, 2011 1:40 AM PDT

I have a Dell Inspiron 1720 which I upgraded to Windows 7. When I did that I began having battery charging problems, which is apparently common. I did not have issue on XP. I had this issue on original battery which continued for a long time until I noticed that the system no longer recognized the battery. I purchased a new battery and same issue. The new battery is recognized and is charged to 69% currently.

I have already uninstalled the battery through the device manager and restarted, but no change.

The computer runs on the battery if I unplug, and the computer runs on the AC adapter. I assume that the battery is capable of charging because it is brand new. Therefore, it seems that it is a Windows problem.

Please help. Is it possible that it is a hardware issue? Is there an after market power management program that can fix it? Is it a BIOS issue? Dell did not make Windows 7 Drivers for my system, but all the hardware works, just this battery issue.

Why yes it can be.

With those battery fires many changes happened to lock out third party batteries and chargers.

To see if it's WIndows 7 I have to install the OS the laptop came with.

I can do a format and install XP pretty easily - or Vista. The computer came with Vista, but it's never been run with Vista. Which would you prefer? Everything worked fine with the original battery and XP, but I want 7 on this computer for the networking abilities. To change, I will use a spare hard drive and just install the new OS on that instead of reformating the hard drive in the system.

There's even a simpler test.

Turn off the laptop. Now plug in the AC adapter and does the battery charge?

If not, it's not some OS issue.

is a confusing W7 expression. It means the battery is plugged in but not charging either because the battery is full or nearly full or the battery is dead or the charging circuitry is dysfunctional or ... I just don't know how many more situations can cause that expression!

Try using the laptop on battery power for an hour, then plug in AC and check if it is charging.

Well, I don't know what I did, but it's fixed now. It charged up the other battery too, the one I thought was dead, as well as the new one. I had the battery removed for a couple days to prevent it being drained like the original one was. I put it back in with the computer powered down, and then turned it back on about an hour later and it started charging. Then switched the batteries to the old one that was completely dead and it began charging immediately.
