BIOS Beeps
Hey there Tom! Sorry for the slow response, but have had too many irons in the fire at the same time, as of late.
Sounds like you may have a case of , what I call "RIC" (Repair Induced Confusion).
Nothing to be ashamed of. We all experience it from time to time, whether novice or professional. I don't know if it is a fungus or bacteria, but I think that the manufactures' pour a little of it in many electronic devices. As soon as you open the cover to attempt a simple repair, you get the disease. Once you contract the disease, anything and everything you touch seems to turn to ****. From personal experience, I can say that it is reoccurring and once you get it, it will usually last the rest of the day, or until you get that item finally repaired ; which ever is longer.
It causes a person to not get things reseated correctly; or to plug things into the wrong place; or to unintentionally loosen a different connector; or to do things that make perfect sense at the time (but someone else would look at it and say "Boy,was that a dumb thing to do!")
Usually, the fix for this is to very slowly, methodically and carefully go through the entire device and reseat anything that is reseatable. Cables, connectors, hard drives, CD drives, memory, modules, batteries (excepting maybe, the CMOS battery) and so forth. While doing this, keep your eyes open and check for anything that shouldn't be there. I have had small pieces of wire, solder balls, used staples, extra screws and such creep from my work area into whatever I have been working on.
If this doesn't work the first time, take a break and try it again. Go get a cup of coffee, take a walk around the block, go out and mow the lawn. Then set down and try it again.
Hope this helps and best of luck!
