Not Start up, Key board and Mouse not WORKING

Question

I have Pavilion G7-2017us Notebook and it has Windows 7 operation system. Symptom: Start the computer, go through to the windowns log-in page, but Keyboard and mouse are frozen, not WORKING. Can't log in. 
force Poweroff computer and use ESC, F9 can go to system diagnose page, keyboard and mouse are WORKING now. Tried "Start-up test",
Processor Check,Memory Test, Hard Disk SMART Check are Passed. Only Hard Disk Short DST is failed. Failure ID : GLMP00-69B7NV-MFPX1G-60SJ03
So Start-up test is FAILED. Tried "System Tune-up", Processor Check,Hard Disk SMART Check are Passed. Only Hard Disk Short DST is failed.
Failure ID : GLMP00-69B7NV-MFPX1G-60SJ03.So System Tune-up Is FAILED. Tried "Hard Disk Test", Hard Disk SMART Check is Passed and Only Hard Disk Short DST is failed.Failure ID : GLMP00-69B7NV-MFPX1G-60SJ03.
So Hard Disk Test Is FAILED. When I performed above test, keyboard and mouse were WORKING properly. Tried Safe mode, but can not log-in because keyboard and mouse are not working at that time. I cared about documents and was able to copy some files to external harddisk under DOS command interface. But right now I can not adjust
this laptop back to normal DOS from safe mode log-in. When I started up it. it goes through to log-in page in Safe mode. Also F11 is not
working because I did not make system recovery point and it can not be recoveried. Please help me for this issue. Thank you very much.

Thank you, Visruth.    When you said the failure ID indicates failling or failed HDD, do you mean that the old HDD is bad and probably all the data on it will be lost ?    Yes, in order to salvage data from the old HDD,  I have tried to buy an external enclosure and take that harddrive out to make an external hard drive. Connect it through USB , but the new laptop can not recognize it and I can see this external hard drive shown in the device manager, but I can not see more detailed information of that drive. Click it and it asks that do you want to format that drive?      So I would like to salvage data from the old HDD. I have been able to enter into DOS command in the old laptop and copied all data on my desktop in C drive. But right now I have forced this old laptop to run into safe mode, which I think maybe I have a chance. But keyboard and mouse are still frozen at log-in page. I do not know how to get back to DOS command as I did before. If I can go back to DOS command, I may use DOS Xcopy to copy out all my data in the old HDD to new external drive. Would you please show me how to get back to DOS command from safe mode log in? I have tried F8, F9. no success.   Another way I am thinking is that to take the old HDD as an external drive, connect to a new laptop, change that new laptop's start up sequence, put the USB external drive start up as the first choice. I really do not know why my keyboard and mouse in the old laoptop do not work at some time (log-in page). Please let me know your advice. Thank you very much.
