Hello, I have an issue when trying to charge my battery. I have a third party battery that is honestly not very good but it is what it is. Anyway, the problem is that when I plug in my power supply to my battery, it says that it is plugged in but the battery is not charging. Now, I have gone through the protocol trying to resolve this problem. I have uninstalled the Microsoft ACPI-Compliant Control Battery Method multiple times. I have also ordered a new power supply as my OEM one was a bit frayed but was still working (temperamentally, however).

The specs of those power supplies are as follows:
OEM: Input: 100-240V ~ 2.5A 50-60 Hz
Output: 19.5V ~ 6.7A

Aftermarket one: Input: 100-240V ~ 2.0A 50-60 Hz
Output: 19.5V ~ 4.62A

Also, I do get an error every time I boot up the system saying that "WARNING: the battery is not recommended for this system, it will not charge, press F1 to continue or F2 to run setup."
My question is, why is my battery not charging and how can I go about combating this issue. Thanks again.

EDIT: The battery I have in right now is brand new. I have burned through 3 previous ones however. This is the battery I have. Battery Link
I understand that the warning message says that the battery will not charge but like I said, this is my fourth battery of that brand and they all charged fine even though that message would appear on start up for all of them.

I have a dell xps and get the same message after I bought a replacement (non-dell) battery.  Every time I login I get this message and have to hit the F1 key.  I think it's dell's way to force me to buy their battery which is overpriced of course.  I may end up returning the battery and buying the dell battery, but I'm not buying another laptop from them.  $120 for a single battery is a rip.  The 3rd party battery I bought was less than half that price which seems fair. 

 

NOTE: the battery does indeed charge, but the message at boot is too annoying.  If I could bypass the message without pressing the F1, I would be good with that.

I just picked up a 3rd party battery for my Dell XPS l502x and had the same issue.  Apparently, Dell has some chip in the battery that tells the computer it is a Dell battery and if not detected, the BIOS produces the warning.  You'll notice it says F1 to continue or F2 to setup.  If you hit F2, you'll get into the BIOS setup.  Right arrow to the Advanced menu, arrow down to Adapter Warnings, hit Enter, select Disabled, hit Enter, F10 to save and exit.  Problem solved! No more annoying warnings! 

 

Since the setting says Adapter Warning, I overlooked it at first, but today I tried it (knowing how sneaky Dell is).  One caveat; I am using a factory issue Dell Power Adapter, so I would not recommend doing this if you have a 3rd party power adapter since you are bypassing a level of protection.

Good fix Guitar-Zan - thank you.  And sensible warning about the 3rd Party Adaptor danger.
