I am currently using Ubuntu 9.04 Juanty on my AA0 1.5gb 120gb netbook. I seem to be having problems with the performance of the machine. Using the netbook remix interface there is a long pause between clicking on an icon e.g Home and that window actually opening. I also noticed that during video and audio playbad the content stops/pauses every 30 seconds or so, this seems to coincide with the HDD making a clicking sound. I'm told this is due to a power/drive saving feature called Automatic Power Management (APM) - can anyone tell me how to disable this? I have also noticed that if i leave my netbook on for long periods 7+ hours, or close the lid and wake it back up, I lose wifi connection and cannot reconnect without restarting the computer. Any thougths would be appriciated.
