Hello, My keyboard and mouse ps2 ports (round green and purple ones) on the back of my PC aren’t working. The keyboard works on another PC and the mouse works in the USB ports. I did some goggling on this and it seems the ports are likely part of the motherboard and that the mother board would have to be replaced. If that is correct, is this an indicator that my mother board is going to go next? Can those ports be replaced easily? Or would I be better off getting a PS/2 to USB adapter I have a 4 year old Compaq Presario SR2170NX, Windows Vita Home Basic. Thanks for any help you can provide. Denise

Hi Denise, Its unusual for ps2 ports to stop working.... make sure you have the keyboard and mouse plugged in correctly..... examine carefully the pins on the end of the plugs... are the pins all Ok.... none broken or bent...( this is the most common cause of problems that we see in the workshop..) Next make sure you have them in the correct ports.... most are colour coded these days.... green and purple..... Remember "a mouse likes green cheese! so mouse goes to the green and keyboard to purple!. However the "first aid" is as follows: 1 Try and use usb keyboard and usb mouse.... does this work? 2 Go to "Device Manager" and uninstall the ps2 keyboard.... close down your machine, and after 30 seconds with a blank black screreen restart... Windows should reinstall the drivers and this may do the trick for you. Let us know how you go Regards paws

Hi Paws, There isn’t a Ps2 keyboard listing in the device manager. I picked up a new keyboard with a usb connector and it works. Yeah! I tried a ps2 connector mouse and that also does not work and also is not listed in the device manger. But the usb one shows up in the list and works. Can I reinstall the Ps2 connectors? Thanks, Denise

Thats good news that you can continue to use your computer using USB keyboard and mouse..... Well done I would be inclined to leave it at that..... however the next step (if you want to pursue it) is to enter the BIOS of your computer and ensure that legacy support for PS2 Keyboard/mouse is enabled, if its not then enable it, save the settings and when your computer has started wait 5 minutes( by the clock) and then close it down. Wait 30 seconds with a blank black screen, then remove your USB keyboard and mouse and replace the Ps2 Keyboard and mouse..... boot the computer and see if it works OK with the Ps2's Let us know how things go Lots of other things you can try.... but let's do one at a time! Regards paws

Hi Paws, The easy answer would be to just use my front USB ports. But now I am curious. I don’t really know anything about BIOS. Is this a simple enough process you could walk me through? Thanks, Denise

Hi Denise,
Ok

The easy answer would be to just use my front USB ports.

or you could use the back ones, most mice will work OK via a hub ( USB hub non powered, will be OK) available for a pound or a dollar or so .
Here's a recent link to the sort of thing I have in mind
http://www.ebay.co.u...=item335dc0b093
The keyboard is best directly plugged into a USB port and not via a hub....( but some do work OK that way!)

Wwhen you start up your machine you may see on the screen a line of text....... something like:
press F12 to enter "Set Up"
or it may be F2 or Del, or Esc...( various computer manufacturers have different key strokes...) and you may need to check your computer or motherboard handbook/manual for the exact keystroke.... However all of them require you to start hitting the appropriate key stoke IMMEDIATELY you power on (dont wait for any part of Windows to start loading as the BIOS operates before Windows even starts to load....)

Once you are in the BIOS tread very carefullyDO NOT alter anything just to see what might happen!
only alter the setting to provide legacy support for PS2...... you will have to dig around to find it.....
If you mess up at all then exit the BIOS without saving the changes Repeat without saving...... this will enable you to try again later.....
You have to be accurate and precise in the BIOS... never guess only act on certainty...... putting in an incorrect setting could stop your machine from booting up!
Once you alter the correct setting then exit the BIOS with saving the changes, and your computer will/should reboot!
Good luck
Regards

Hi Paws, I think I'll stick to the usb port. The BIOS is sounding a bit scary. Thanks again for all your hep. Denise

Hello,

 

I have the same question.  If the keyboard isn't functioning I can't use the ways you suggested to start BIOS.  Is there a way to start BIOS without a keyboard?  Maybe I'm just missing something - not the first time.  Thanks.
