The keyboard can t connect to the host, post error occursWhat does it mean 5

There are generally several reasons why the keyboard cannot connect to the host and prompt post error occurs:

1. It may be that the keyboard is broken, or the performance of the motherboard interface is unstable;

2. If it is a PS2 keyboard, you must connect the keyboard first, and then turn it on to work;

3. Post error occurs is caused by the BIOS self-test but fails, you can enter the BIOS to clear the error message. If the self-test fails, it will definitely not enter the system;

4. In this case, be sure to turn off the computer, reinsert the keyboard, and then turn it on, maybe it can solve the problem.

This prompt means that the motherboard POST did not pass, it may be that there is a problem with your keyboard interface, or it may be caused by your BIOS setting error, you can clear the CMOS and try it?

I saw a round and shiny big thing on the motherboard, he is the button battery on the motherboard, unplug it and put it for a minute (try to be longer), go up, if it doesn't work, observe the jumper around the battery, generally three, wear a hat, such as a hat on , you take it off, get it, and then power it on, and then connect it back. That should do the trick.

It looks like the mouse interface of the motherboard is broken.

There is no ...... answer to this problem

Keyboard problems, change the keyboard.

Hardware failure alarm,Computer startup found an error in the process of power-on self-test,keyboard。。。 It is recommended that you change the keyboard and connect it to the computer and reboot it again. I hope my answer will help you.

Flash the motherboard and you should be fine.

This is caused by the motherboard self-test failing to pass, and the hardware or BIOS settings are incorrect. Try powering off first, remove the motherboard battery, wait 3 minutes and then turn it back on, if you still have problems, check your hardware.

You** can't shoot completely, and you can't see the previous tips.

Tip: It may be a keyboard error, try reconnecting the keyboard.

When you boot up, keep pressing F8 until the Select OS appears, and you select the last correct configuration

Try clearing the CMOS?

I saw a round one on the motherboard, a big bright thing, ok we are looking for him, button battery, unplug it and put it for a minute, go up, if it doesn't work, observe that the jumper around the battery is generally three, wear a hat, such as the hat is worn on , you take it off, get it, and then power it on, and then connect it back, and it's done!

Every time the COMS battery is replaced, the CMOS needs to be cleared, method: there is a three-pin jumper near the CMOS battery, and the two-pin jumper on one side is shorted by a jumper cap; Jump the jumper cap on the other side, just short it, jump back to the original position immediately, and try to power it on again.

In addition, if the battery is not properly installed, it may cause a similar phenomenon. If not, it is recommended to reinstall the battery once.

Are you sure the battery is right?

The motherboard uses CR2032, but there is a CR2025 on the market, which looks very similar, but the thickness is not enough, and it is useless to install it.

You take it down and take a look, if it doesn't work, just look at the upstairs method.

It is recommended to reinstall the battery once to try.
