I knew this wasn't the original Sony charger for my Vaio, but I assumed power is power. Well, upon using it for the first time, I noticed my touchpad's mouse would not properly respond to my movements. It was quite bizarre and frustrating considering this was a new laptop. I thought it was the computer. Until, I moved my comp back upstairs to the OEM charger where it works fine. But, the second I plug it into this charger - the mouse freezes and has a delay.<br /><br />Point is, yes, it charges the battery. But, if you want to USE the computer while it's charging, good luck. I just wonder if it is affecting anything else that I should be concerned about? Eek.
Affected my mouse function!?!
