Chat Disappointing

I do not believe in contact "Support" of any kind until I reach a point where I cannot resolve an issue myself.  I have had a couple of "minor" concerns with my XPS 17-9730 Laptop.  The battery will blink orange/red for a millisecond or so when I first turn on the laptop and then everything is fine.  Light changes to white and then goes out.  No problems.  But - reading about this millisecond orange / red blip says there could be a battery / hardware issue.  It is nice to know that this website has Diagnostics and Tools abilities and Drivers and Downloads capabilities.  The chat agent I worked with said I should shut down the computer, turn it back on and then press F12 repeatedly until it brought up the Diagnostics.  That does not work.  Thank goodness for this website, which he did not even mention.  The other problem was with the Support Assist App.  Dell really needs to get on this problem.  I do not enjoy having to "uninstall" Support Assist and then "reinstall" Support Assist to get it to work.  That should just not be happening.  Maybe there are some people out there who set up a "chat" with what should be easily resolvable problems.  Recently, I solved a problem revolving around my laptop not doing a complete shutdown which was wreaking havoc on apps, etc.  I did a lot of research and learned about the "event viewer" which shows if the laptop does a complete shutdown when you turn it off.  There is a method to insure that the computer does, in fact, totally do a clean shutdown when you turn it off - disable "fast start".  It takes longer for the laptop to boot up now, but there are no more "overload" issues (or whatever you want to call them).  You do not want the laptop to enter some kind of hibernation or sleep mode when you turn it off.  I feel like the chat agents harbor some kind of resentment because people are not sufficiently proactive in trying to resolve their own issues.  I may have to remove all the screws from the laptop bottom to check to see if the battery cable is tight, but honestly, right now I am not in the mood.  I would also have to watch some YouTube videos on what exactly to look for if there is a possible loose cable.  When I ran the hardware scan and diagnostics, it said everything was fine - including the battery.  So - if the battery performance seriously degrades, then perhaps I will bite the bullet and remove the laptop bottom.  Or - I could take it to Data Doctors and let them do the honors.  There is one item I am kind of experiencing tech phobia with - having to use "Command Prompt".  As far as I am concerned, if "Command Prompt" is going to be involved, chances are I am going to schedule a remote session with a tech support person and let them "have at it".  Seeing I am paying Dell a month fee for software support, I do not think that is an unreasonable expectation.  Long story short - I will spare Dell's tech people as much as I can, but when I do reach out to them, which is infrequently, I expect they will be pleasant, patient, helpful and understanding and provide "accurate" information on how to access things like "Diagnostics and Tools" on the support website rather than shutting down, booting up and pushing F12.  The learning process is unending. . . .
