I have HP pavilion 2200 series laptop with AMD processor, 1GB RAM, on board nvidia display card. It suddenly cause following problem:
When the adapter is unplugged, the touchpad works correctly and smoothly. But as soon as it is connected, the cursor response badly but when i use external usb mouse, It works fine.
I have check somewhat same question here, It tell me that it is somewhat regarding power supply issue, but it is little different then this one.
I have my original adapter but few days before i have given it to vendor for service due to slow speed Blue Screen issue with OS.
Does anyone know that how to troubleshoot this????
