Tekram K7KX-A PS/2 keyboard will not work. Get Adapter

I powered off my system to swap hard drives.
When I restarted the system BIOS and the OS on the swapped drive had compatibility issues. My next step was to power down again, remove the battery and clear CMOS.

After reinstalling the battery and placing the CMOS jumper back to 'normal' when I powered up again the system would not detect my PS2 keyboard. DEL and F1 had no effect. Swapped out keyboard - no help.

Final solution: Get a USB-to-PS/2 Adapter. This allows the PS/2 keyboard and mouse to connect through a USB port. Belkin Part # F5U119vE1

The only thing I can suggest in this scenario, is to go through your BIOS again, and check for options to enable/disable your PS2 ports, and that's the best-case outcome.

worst case outcome is that when you were swapping your hard drives, an improper circuit was made, and static (ESD) killed a component on your motherboard. Did you use a grounding strap, or ground yourself when you had the case open? another thing to check for, is if the wires connecting the ports are whole, and not bent or loose.

if this doesn't help, i'd definatly go with the USB adapter, to see if that works. if not, there is a possibility you might have to buy a new motherboard, in itself.

GA- F2A85X-UP4, can't bring up initial bios, upon build

Gigabyte motherboards boot to BIOS setup by pressing 'del' at startup. if this doesn't work, it may mean that the boot-time usb support for keyboards isn't activated, which means your usb-keyboard only works when windows is loaded. if you have a usb-keyboard, you can get around this by attaching a PS-2 keyboard or putting a PS-2 adapter between your keyboard and the pc.

I have a ps/2 keyboard but my ps/2 keyboard com port not working. so i sold a USB keyboard but my CMOS settings are enabled only i canot entre CMOS setting by keyboard

Unfortunately BIOS reset will not help you, the default setting for USB keyboard support is set to OS and you need set it to BIOS. I would recommend you to go with your mainboard to a specialized service, sometimes the problem is only a defective capacitor. If you reset your CMOS, the first boot device will be set to Floppy. You could try updating your BIOS to the latest version (maybe in that version the USB keyboard is set to BIOS) but I don't know if you can create a batch file to update the BIOS automatically, without confirmation from keyboard... The reliable solution is the technician. You can also try to connect your PS2 keyboard to the mainboard using an USB adapter but as I know in that case the keyboard is treated as an USB device...

If this is the solution for your problem, please rate my post, otherwise give us more details.

Powers up no video and mouse stays lit when powers off

This is an old motherboard, with this in mind there are a couple things for you to try. Power off the system and unplug the power cable from the power supply. Remove the left side of you're case. Touch any metal surface to discharge possible static.
First clear the cmos jumper on the motherboard. See page 1-17 in you're manual for the location of the cmos battery and cmos jumper. Also see page 1-21 to clear / reset the cmos battery. (Don't forget to set the jumper back to normal after 30 seconds.
Doing this will reset the bios to its default setting.
If you added a graphics card to one of the PCI slots remove it.
(For now).
Re-connect the power cord for the power supply and power-on the system. If the motherboards built in VGA controller is working you should have display on your monitor and since we cleared the cmos the bios will want you to enter the bios to adjust all its settings.
If you do not have display than the onboard controller is defective. You can add a PCI video card into any one of the 3 (White in color PCI slots). It’s not uncommon for the mouse to stay lit. If you're mouse is plugged into a PS-2 port try un-plugging it when the system is off.
Then re-connect it with the system off. You can also buy a USB to PS-2 adapter. Most new mice and keyboards come with this type of adapter. See the link provided;
If you're mouse and keyboard are PS-2 and connects to the system by USB, try another opened USB port. The next link opends to Biostar and you're motherboard;

My bios speaker will beep on startup but nothing more. What avenue should I approach to get past this part of startup?

First you need to know which BIOS you have and how many beeps it is producing... these beeps are the POST - Power On Self Test. They tell us if there are problems such as missing keyboard, video card not working, memory faults etc...

Then you need to go to the appropriate BIOS site and see what the number of beeps mean.

If it is a single beep - it means all is well...
As you are not getting anything more you should check to see if the Hard Drive (HD) light flashes - if so - the HD is probably operating ok and loading your system but there is either a problem with your monitor or video card... borrow another monitor and see if that helps...

But it all depends on the number of beeps you get and what kind - long and short beeps (like morse code).

If this helped you at all please vote!

System wont boot

Disconnect all devices except keyboard and mouse and master cd or DVD. unplug then hit power button. Plug back in. Hit power and hopefully you get to BIOS. If you do make sure you save the BIOS before you leave to start OS. Keep me informed and I'll keep checking your listing to see if its working or not.

Keyboard/Mouse Plugged in NO VIDEO NO Keyboard/mouse plugged in VIDEO ???

Apparently there is something confilcting with something ot the ps2 ports are faulty! We'll need to find out! Try plugging up your system without the video card but the ps/2 devices plugged in! (we don't need to plug up hard drive, so plug them out if they are plugged in) When the system comes on(after your hear the POST beep, if the system speakers is plugged up to the motherboard). Try pressing NUM LOCK or CAPS LOCk to see if the light come on and off. If they do that means your machine is responding with the PS/2, if not then you need to find a PS/2 expansion adapter ot use a USB Keyboard and mouse! If you do get a response that means your ports are working and there is probably a confilct with your Video card! In that case, I assume you've already reset the cmos(if you haven't then do that). Also if you have an AGP port try an AGP Card, if you were using an AGP card try a PCI! Well the USB keyboard more than likely will work! try these out and get back to me! regards, babb
