I recently received a fairly new sony vaio PCV-RS720G computer from a family member after it had been sent to the company to get the hard drive fixed. They had not turned it on since they got it back but when I did the keyboard and mouse will not function. They are PS-2 connected. I also tried to plug in a usb mouse and that will not work either. When they are pluged in and the computer is on they light up so they get power.
This may be obvious but please do check the connectors, sometimes they are loose or sometimes they are connected to each other inputs. Also check in the bios configuration if you have the "plug and play" option active so the PC will recognize any new peripheral when it is plugged in.

I HAVE A SONY PCV-RX651. THE MOUSE DOES NOT WORK. I BOUGHT A NEW ONE AND IT STILL DOES NOT WORK. SINCE I CAN'T USE THE MOUSE I CAN'T SELECT ANYTHING ON THE COMPUTER. THE CONNECTIONS ARE GOOD AND EVERYTHING HAS POWER.
