Core i7-3630QM Multicore issue with V3-571G-73618G75Makk

Hello there,

 

I think something went wrong with the Bios version 1.13 of Acer Aspire V3-571G. In windows 7 x64, I went to Windows Task Manager ->  Performance, there was only 2 CPU Usage History bars in the report. I double checked with dxdiag command, at the line Processor, it showed: Intel Core i7(TM)-3630QM CPU @ 2.4Ghz (2CPUs) 2.4 GHz. I downloaded CPU-Z in order to check the real core of i7, CPU-Z just showed me: Cores: 1 Threads: 2.

 

I went to BIOS setting by pressing F2  during the booting, there is no place to enable all cores.

Does any has the same issue? If you do, please share me your experience on how to fix this issue.

 

My system:

_Win 7 x64

_BIOS: InsydeH2O version 03.71.48.V1.13

Thank you very much.
