I want to add a PS2 keyboard to my laptop running Windows 7 64 bit using a PS2 to USB converter, but I couldn't get it to work and there are no related configuration options in the BIOS screens.

But when I connect the keyboard to laptop nothing happens. What should I do?

The obvious question, have you restarted your Laptop after doing this? – Joe Taylor Jul 12 '11 at 14:22
Yes U also restarted the laptop. – shaahin Jul 12 '11 at 14:28
Silly question, but are you sure the adapter even works? Try it on another machine. – Shinrai Jul 12 '11 at 14:28
I don't like an USB port as a KB-/ mouseport. Am I a dissident? – Aki Jul 13 '11 at 14:18
Please don't post your question multiple times. If you need to add more information to your question, use the edit link under your original post. – nhinkle Jul 13 '11 at 15:07

Are you sure you have a signal convertor rather than an adapter? explains the difference.

Ooh, good point. If it's an old enough keyboard it probably isn't putting out a compatible signal. – Shinrai Jul 12 '11 at 17:20


This is a very common adapter and when USB started to become widespread, pretty much all micr came with an adapter.

They are very cheap and your best bet is probably eBay unless you have a cheap computer shop near by.

Please bear in mind that the keyboard has to support this adapter for it to work. These adapters are just pass-through connectors that change the pin orientation, but the keyboard has to support auto-detection of the protocol it's using. If the keyboard originally came with one of these and you lost it, then it'll work. If it didn't... it might work. Maybe. – Darth Android Jul 13 '11 at 13:52
@Darth Android... Do you have any sources? I have never heard of this and have used cheap keyboards without problems... Interested to read up! – William Hilsum Jul 13 '11 at 14:10
Based upon your answer and other answers here. Unless you are talking about a different device than the ones mentioned in that question, I imagine the same information is still valid. If you are talking about a different device (one that has internal circuitry and actually converts the PS/2 signals into USB signals), then you should provide some way to identify this and clarify your answer. :) – Darth Android Jul 13 '11 at 15:56
@WilliamHilsum I can confirm that such an adapter did not work for me with an old brand-less keyboard included with an old PC (256MB RAM). Another report on – Lekensteyn Jun 2 '13 at 14:01

PS/2 to USB Adapter

This adapter on Amazon has a chip in it that will take even your old non-USB compatible keyboards and allow them to work over USB.
