Hi, everyone. Welcome to the county A plus tips is zero dash Windsor's or one mother one.
Today's lesson is lesson one that a bios built in diagnostics, post air code and things the technician may encounter. I'm the instructor, Bill Price.
So today's lesson objectives review of the postcard in the postcard ares that we talked about in a previous lesson. And also we're gonna talk a little bit about Bill Gate Diagnostics tools in the motherboard. So let's begin.
So, as you remember from a previous lesson, we talked about the postcard, the postcard to be used to monitor systems, power and self test.
Oh, our diagnose problems with it.
Now, the post code is a two digit hexi decimal code generator down during the power on self test. So again you would use the postcard. Say, for instance, when your PC or your sister Eun is not booting up properly. You would put this card ian, and it would display a two digit hexi decimal cold,
and you would have to look into the course party vendors manual to determine what that code is actually trying to tell you
it could be a RAM issue. Ah, hardware issue or problem with the board itself.
So no the particular vendor on the motherboard that you're working with
and you could use this postcard plugging it. It kind of determined what's going on.
Now. Let's talk a little bit about the Bill De and Diagnostics test that each motherboard they have now
Mother board manufacturers approached is very differently. So the little varied opinion again on the motherboard manufactured that you're using
the text based versus the U F E F. I would be a little bit different and there's even see from its slide. This is just a screen shot of a a quick cell test from the U E F I type moment before, and you could see there was a system ram in a video ram Hardware fiddle here.
So let's look at a couple of more examples.
The screen shot on the right. You can see that this particular vendor has a full diagnostics menu that you can run tests against different hardware components. Where is on the right? This diagnostics is just a couple, depending on the hard drive and the memory test that you go run so again, just want to give you an example that
this was very depending on the manufacturer. So no Indian, the manufacturer, the motherboard that you're going into second troubleshooting.
Okay, so let's reviews. Today we talked about and had a review of the postcode postcode in the post courtiers.
We talked a little bit about the built in diagnostics tools that varying manufacturers may have in their systems. Know that these tools exist and help you troubleshoot and overcome problems that you have experience in the field. Okay,
a great lesson. I will see you in the next lesson.
