And watch carefully for anything unplugged along the way. As there are a few connections I can't tell you which it is.
I opened up my laptop to install new RAM, i had to take apart most of the components to get to where the RAM is at. I put everything back together and it wouldn't power up on the battery....So I plugged my power cable in and it powers up from it.
Any reason what may be causing this? I reopened everything back up and everything is plugged back in.
