Laptop power issues only affecting MindMaanger performance
So my 3 year old Dell Precision laptop continues to have some power issues ('input power not determined messages' or the battery not charging when plugged in) periodically that replacing the power brick and motherboard have not fixed :-(. However when it's acting up, this only seems to affect MindManager, making it run very, very slowly and/or crash repeatedly when doing particular operations, Other software does not seem to be affected.
I am wondering if there is something in the software architecture that makes it behave that way? For example it can take 3 minutes for it to add a single tag to a particular branch from the index pane when the laptop is plugged in, but only take half the time to do the same operation if it's unplugged. It's a large map with 1000's of tags in 20 or so groups so this possibly doesn't help, but doesn't explain the phenomena of the plug.
I am tearing my hair out over this one as it makes developing the map with new content almost impossible. However I don't want to replace the laptop if it's not going to solve the problem (especially as other software operations are not affected).
Again thanking you in advance.
PS - In the case of adding tags to branches I note tht the operation takes a lot longer if adding them from the open Index pane as opposed to via the top menu or right click menu. In fact most operations slow down if the index pane is visible
