It has nothing to do with Windows 7. This is a hardware issue. Either your charger is just barely putting out enough to run the machine but not enough to charge the battery or the charging circuit in the laptop is shot. It takes more voltage than the battery puts out to charge it but only about the same as the battery to run the laptop. It could be either so if you have someone with the same brand laptop, see if you can borrow their charger for long enough to see if it takes a charge.
The third possibility (though rare) is that the replacement battery you purchased is bad.
If the charger or even the charging circuit is bad then the original battery might still be good if charged well and soon.

Thanks for your help, and that seems to make sense, moreso than all of this other stuff I'm trying...
feel like I'm the victim of a bad practical joke so far...the "fixes" are falling just short of standing on one leg while plugging it in, or rubbing my tummy and patting my head while starting up, etc.

I would like to mention that it's the AC adapter that came with the system..I have a new Alienware 17 with a bigger, more heavy dutyish AC adapter, and Im going to give it a try. I would imagine it will be a mismatch though, would the adapters voltage, output etc need to be tailored to the unit that it's charging? Or are they pretty standard?

Don't be swapping in other chargers unless you've checked that the voltage and polarity are the same for both.

What battery did you install--a Dell OEM or some off-brand from China that are everywhere on ebay?

Well I tried to get what I thought would be a decent one, with good reviews and a warranty, and I wanted to avoid the 10-15$ batteries you see everywhere online. We paid $50-60 IIRC (that doesn't mean anything i know). But to answer your question it's an off brand "Made In China" type after all I guess.
LB1 High Performance Batteries is the name of the outfit I guess, or just the name of this battery maybe..but yea "Made In China"..

I hate to admit it but I'm actually doubting we even needed a new battery now. I should've known better but I just looked for and bought a battery when my wife told me the one in her laptop was dead and needed replacing. I thought she'd had it diagnosed or knew for sure somehow it needed one but I found out today that she "just figured" it was the battery since it will only run when plugged in.

Im wondering if the DC power jack needs replacing as it's quite a fragile situation when the adapter is plugged in. If she doesn't keep it supported with electrical tape it'll usually fall right out which shuts the computer down. Thanks for your help.

Probably most of the laptop batteries are made in China but there are different manufacturing standards and the real cheap ones on ebay can fail pretty quickly. It sounds like you got one of the better ones.

Dell will have different amperage chargers that will work with your laptop. You might check to see what you have now and get a more powerful one. (The voltage will be the same.) If so, and if you look on ebay as I usually do, I think you're better off with a used Dell OEM than one of the new replacement chargers from China.

As Fingers mentioned, it's usually the battery or charger. I guess another possibility is the charging circuitry inside the laptop but let's not go there for now.

Oh, also check that the battery is fitting tightly and the contacts are clean.

If the charging plug is falling out it could also be the plug or the charging jack. The new charger will have a new plug and I believe that Dell charging jacks should be replaceable with only a minor operation if you are handy. If needed see if Dell's site has details on replacing (HP I know have a service manual downloadable complete with part numbers) or Google it as there are probably tons of facebook videos on how-to repair nearly everything these days. If one is not clear then try another one until it is clear to you.
