Mouse and keyboard on my computer won't work on start up. I tried ps2 adapter on usb mouse but nothing works. When turned on goes through microsoft repair and Restore option and I can't do anything

SOURCE: Mouse not recognized/ mouse port not working

I kept hold about 30 seconds the blue light button on the USB controller device and it worked!. I guess that's the way to sinchronize both the mouse and the USB controller of the mouse. Ramón.

SOURCE: Bios does not find PS2 keyboard/mouse

I have a computer that stops at.... Keyboard and mouse not found Checksum error. Defaults loaded. Press Del to enter setup. F1 to continue. With no keyboard, unless you know different I can not access the BIOS setup. Problem not fixed. Await suggestions, something better than fit a new motherboard please.

SOURCE: USB mouse not recognized

I have similar problem. 2 inland KVM's (both have PS2 inputs, one has USB outputs) do not light or recognize my usb mouse with a PS2 adapter. They do recognize a PS2 ball mouse on the KVM's however. One of the computers (Sony vaio 1.5 GHz) does recognize a usb mouse with adapter on 2 other KVM's (Old Belkin and a Trendnet) (the second computer I have not tried in those configurations). Next I will try an optical mouse with a PS2 fitting. That did work with a fifth KVM at an auto business last week.

CHECK BIOS TO MAKE SURE IT DID NOT TURN ITSELF OFF WHEN YOU PLUGGED IT INTO THE USB.BIOS MAY HAVE TURNED IT OFF TO PREVENT A CONFLICT.RICHARDM69

SOURCE: USB Keyboard and mouse wont work with PS2 KVM with adapter

Don't use USB-PS2 adapters if the keyboard/mouse doesn't support such adapters. They aren't universal, they work only with some "smart" (or chinese) keyboards that can detect the connection type and switch between USB and PS/2.
