Upgraded RAM on Macbook Pro, Battery Issues

Good afternoon Bright Ones!

So I have an Early 2011 MBP with the 2.3 Ghz i5 and running OS X 10.8.2

Yesterday, I thought it would be a great idea to upgrade the RAM on my little friend. I was super careful with anti-static procedures and workspace cleanliness. The memory replacement went off without a hitch in that the computer booted right up and the new memory is showing in the "About This Mac" screen, BUT now the MBP will not run on its internal battery at all. I am getting the 'X" over the battery icon and the green light is staying illuminated on the charger. In the System Report => Hardware => Power => Battery Information scree, it is showing as No Battery Installed.

Your Mac doesn't detect your battery. First, try to reset the SMC > http://support.apple.com/kb/HT3964

Also, reset the PRAM > http://support.apple.com/kb/HT1379 If it doesn't work, it looks like a hardware problem, so take the Mac to an Apple Store to get it diagnosed and repaired

Thanks for the reply -

When attempting to reset the SMC, what is supposed to happen? More-in, I followed all of the steps but nothing out of the normal start-up parameters happened.

Are there supposed to be additional prompts that I am to follow?

If it's a software problem, your battery must be detected again. It may happen if a SMC setting gets damaged, but it looks like it's a hardware issue. Take the Mac to an Apple Store or reseller

Are you sure you didn't accidentally disconnect any other wires or connections for the battery when you went to replace the memory. Upgrading memory doesn't cause this type of problem and it's as simple as unscrewing the bottom off the laptop, taking the cover off, removing the two old memory modules, installing the new ones and putting the cover back on. If you moved or had to move any cables to do any of the above, you did something wrong.

Well, I consulting quite a few websites regarding the procedure(s) and one in particular, Other World Computing (OWC) had a video in which they suggested to unplug the Battery Connector before removing/reinstalling the memory modules. I'm fairly sure that I got it re-connected as it was.

Could unplugging the Battery Connector cause some sort of reset or something?

That's your problem right there. You followed OWC's writeups. lol

As long as the laptop is turned off (OSX Shut down), there should be no issues, and while I agree that it would be a good idea to disconnect all power sources from the machine, sometimes (for novice users) this can cause problems because breaking a connector or some other bad luch issue could arise.

My suggestion, open the laptop back up and check that you didn't bend any pins or something on that battery connector. The machine isn't seeing the battery, that's your whole problem and that happened because you disconnected it. Figure out what's not right with that battery connection and your problem will be fixed.
