Bios Setup

Today i will tell you about a computer problem. When you start up your computer, have you ever found, dark screen that looks old fashioned DOS type with white text on a black background (as seen in left picture). Dark screen explain something about computer model Software, such as Pentium(R) 4 , Bios version, memory etc etc. but the simple message is
legacy keyboard - detected
legacy mouse - detected
USB Legacy - Enabled

It informs me to strike the "F4 Key" to continue and setup computer settings. When I do, it's take me to Bios Setup Page.
So lets back to the topic that How i found this problem.

1. When main power switch on for my room, Computer turn on automatically without press power button on CPU. ( Normally have to press power button on CPU)

2. Computer screen shows dark screen that looks old fashioned DOS type with white text on a black background. Dark screen explain something about computer model Software, such as Pentium(R) 4 , Bios version, memory etc etc. but the simple message is
legacy keyboard - detected
legacy mouse - detected
USB Legacy - Enabled

It informs me to strike the "F4 Key" to continue and setup computer settings.

3. When I do, it's take me to Bios Setup Page.

4. I tried to change some settings Bios setup page
then press F10 for save and exit from setup page. but it's worthless and problem occur many time or many days when i turn on main power switch in room. So every time i press F10 for save and exit. I thought it's some kind Virus and etc....

5. as i am not expert in computer so i search this problem in Internet. and i did found some question and answer about it. but most of them describe you computer and bios setup. which is i found quite difficult to understand because as i told you i am not an expert in computer. Only few answer are telling you what to do for the problem.

6. I recall few years ago one of my friend help me for change bios battery, so decide to change bios battery. So i went Powerbuy ( IT and electronic store in Thailand) and bought Lithium battery 3V ( model #2032) and change. Then problem is gone so fast...

7. Note: also notice your Computer time, if it's slower or give you wrong time even you set it everyday.

So if your computer also behave as i told you above or computer time and date is slower then local time. it might be the time for change New battery. I told this problem to my friend he don't believe me he ask me where do you put this Lithium battery. :) I hope you know where is the Lithium battery. battery is in Motherboard.

These are few advise from me if you ever get the same problem . try to think when you have change your Bios battery ? or never change?
