Symptoms
On a computer that is running Windows 7, you use the Chkdsk.exe program to schedule a disk check during the next system startup. However, the disk check does not start correctly. Specifically, you may experience one of the following issues the next time that you start the computer:
-
A countdown timer is displayed and you are prompted to press any key if you want to skip the disk check. However, after you press a key, the countdown timer continues. Eventually, the system may stop responding at the count of 1, or start without performing the disk check.
-
The countdown timer is not displayed and the disk check starts immediately.
-
The countdown timer is displayed. However, the disk check starts before the countdown timer reaches zero.
This problem is more likely to occur on computers that have infrared devices equipped.
Note Many portable computers may have built-in infrared devices.
