Thanks, Krissy.
I mostly run the computer on AC all the time -- rarely use it on battery power alone.
I'll try to follow the steps you've listed, but I may have to check back to learn how to accomplish quite a few of them. I'm so un-knowledgeable in the true-tech areas.
I've gotten pretty facile with the graphics and layouts of book designing (which, along with writing, is what I spend most of my computer time on) (when I'm not working at my day job) and managing my own extremely simple websites.
But I should change my moniker to "Techie Neverbe"...
I'll be back!
