A Acer notebook, just get into the system, is running slowly, the boot fan sound big, out of the wind blowing out, so the demolition machine found that the fan out of the wind, export to the blocked, and so cleaned up and then put back, when the boot will appear:
Platinumpas-preboot authenticalion Services Verify
Please insertvalid smartcard
Can't get into the system, even the BIOS is not going to go, depressed, online check to know that this machine to unplug the BIOS battery, and then the boot will be inserted into the smart card to decrypt the line, but this machine smart card lost, this more depressed, the fault also expanded, this should do, It turned out that there was a dip switch next to the CMOS battery, just like the desktop board. So, I try one by one, try to the first 3# switch, the boot will not be an error, the normal access to the system, and finally Panasonic breath. It seems that this dip switch can screen smartcard, I hope to encounter this problem friends help.
