Dear Salman and others, Sorry for the delay. Yesterday I was completely involved in testing process. So could not reply. I could find the source of the problem. Now we have to work out for the permanent solution. Following is the result. But I din’t understand your previous message. 2 days ago, you said that you bought your laptop only 3 days earlier. But in the last message you said that you restored your machine to November 15th. How is it possible? Is your system clock not correct?
To prateek aggarwal, Yes sir. It is due to Audio latency. I downloaded DPC Latency Checker from the following link: http://www.thesycon.de/deu/latency_check.shtml When I first ran it on the system, I got all the red bars on the graph even while there is no sound problem. The latency was varying for every 2-3 seconds from about 2500 micro seconds to 12500 or 13500 micro seconds. While the sound problem was present, the bars touched the sealing of the chart. The latency was recorded in the range of 150000 to 300000 micro seconds. Some times it even went up to 700000 micro seconds. Surprisingly, even when I disabled my realtek soundcard, I got the red bars of same height. Next I suspected network cards. The moment I disabled my wifi card, it dropped to very low in the green region (125 micro seconds). If I re-enable the wifi card, the next second again I got the same red bars. One more thing I like to tell you, if I enable wifi device and turn on it using the switch provided on the laptop, it substantially drops but not to green region. Then I get alternating 2-3 yellow bars (about 1200 micro seconds) and 1 or 2 red bars (about 6300 micro seconds). The earlier observations are when wifi is enabled but switch is off. I also ran my computer for long time to find whether the problem appears after disabling wifi and it ran without trouble for hours. So it is clear that my atheros Wi-Fi card is causing it. Now please tell me sir, what I have to do next for solving that wifi device problem. If you need, I will provide the screen shots of the graphs obtained using DPC latency checker. Salman, as you know this problem does not occur continuously but it comes and goes for some minutes. Hence I was testing it by running my system for long time. So I could not reply in time. I did not install SP3. But if you need it, its download page is http://www.microsoft.com/download/en/confirmation.aspx?id=1260 The following links may also be of some use. http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=24 http://support.microsoft.com/kb/936929 To shona man, Out of curiosity, I want to know. Can we uninstall BIOS with system restore? To Kiran Baug, Do we have difference between Indian and US sites in terms of downloads available for a model?
