So you should try to update BIOS firmware, or if that doesnt work - try to rewrite it with older version of firmware.</p><p>3.2 if the screen perfectly blank - there may be problems with bios APM or ACPI settings ( S1/S2/S3 differs on providing with power internal hardware - read about it here <a href="http://msdn.microsoft.com/en-us/library/ms798270.aspx" rel="nofollow noopener" target="_blank" title="http://msdn.microsoft.com/en-us/library/ms798270.aspx">http://msdn.microsoft.com/e...</a> ) if there any and also - with some additional h/w driver installed in OS. the solution is to change Power Managment settings in bios ( or just reset them to default ), check power managment settings in windows ( what mode has been used - hybernate or suspend?), check in device managment - does PC ACPI mode supported, and try to disable additional hardware drivers installed in system - i.e. bluetooth dongle, tvtuners etc...</p><p>may be this issues could be usefull:<br><a href="http://support.microsoft.com/kb/242495/en/" rel="nofollow noopener" target="_blank" title="http://support.microsoft.com/kb/242495/en/">http://support.microsoft.co...</a><br><a href="http://support.microsoft.com/kb/907477/en/" rel="nofollow noopener" target="_blank" title="http://support.microsoft.com/kb/907477/en/">http://support.microsoft.co...</a><br><a href="http://support.microsoft.com/?kbid=923232" rel="nofollow noopener" target="_blank" title="http://support.microsoft.com/?kbid=923232">http://support.microsoft.co...</a></p><p>this patch fixes some problems too:<br><a href="http://www.microsoft.com/downloads/details.aspx?FamilyID=97a6d0a8-947b-43a9-b415-b551d7c9097a&amp;DisplayLang=en&amp;displaylang=en" rel="nofollow noopener" target="_blank" title="http://www.microsoft.com/downloads/details.aspx?FamilyID=97a6d0a8-947b-43a9-b415-b551d7c9097a&amp;DisplayLang=en&amp;displaylang=en">http://www.microsoft.com/do...</a></p><p>to disable additional hardware use win+r-&gt;devmgmt.msc, right click on device, properties, disable</p><p>to disable additional software, drivers and services use win+r-&gt;msconfig (sorry, my interface isnt in english) in common menu choose "diagnostic startup" or something like this (2nd from the top)</p><p>3.3 concerning video driver problem - yep, may be it must be updated, but sometimes hardware better works with older version of drivers than with updated one. This can solve the problem too.</p><p>3.4 at last - it could be system fault - to solve - use win+r-&gt; sfc.exe /scannow ( this tool will check windows system files, and if any of the are corrupted - will restore them form windows installation (or recovery) disk )</p><p>and afterall may be a good reason to check system event viewer, is there any errors or warnings.</p><p>that's it for question 3 :)</p>prizrakTue, 09 Sep 2008 11:57:54 -0000
