Cannot load TPSMain.exe as CpuPerf.dll not found
Posted on 2008-10-04
My laptop shows an error during XP startup. "TPSMain.exe not able to start due to CpuPerf.dll not found".
I have tried the Toshiba web site and Google as well as EE but I can not find a comprehensive fix. From my research I believe that this dll and exe file role is in the power management utility. The system seems to work OK without it however if I am to squeeze reasonable life out of the battery then I guess this utility needs to function.
I don't have an XP disk with this laptop as the OS came installed and with a backup partition on the hard drive.
I have run PCTOOLs Registry Mechanic. Also run Spyware Doctor and Norton NIS 2008 without sign of any malware using these programs.
I would appreciate advice in regarding repair of this part of the OS.
